Why It’s Important to Know the Battery Continuous and Instantaneous Discharge Current — and Their Duration

When selecting or designing a lithium battery, one of the most important technical factors to understand is the discharge current — both continuous and instantaneous (peak). These parameters directly affect how your battery performs, how long it lasts, and how safely it operates.

At Shenzhen Himax Electronics Co., Ltd., we often emphasize to our customers that understanding discharge current ratings is just as critical as knowing the voltage or capacity. It’s the key to ensuring that the battery truly matches your system’s real power demands.

1. What Continuous and Instantaneous Discharge Current Mean

Continuous discharge current refers to the maximum current a battery can safely deliver on an ongoing basis without overheating or causing damage to its internal structure.

Instantaneous (or peak) discharge current describes the maximum short-term current the battery can deliver, typically for a few seconds, to handle sudden surges such as motor start-ups or load spikes.

In simple terms:

Continuous = the normal, stable power output

Instantaneous = the short burst of extra power

Understanding both ensures your equipment performs smoothly and safely under all operating conditions.

2. Why Knowing These Values Matters

(1) Ensures Proper Performance

If a device demands more current than the battery can continuously provide, voltage will drop and the system may shut down or restart unexpectedly. This is especially common in high-load applications like robotics, electric tools, and e-bikes.
At Himax, our engineers always help customers match the discharge current rating precisely to their load requirements to ensure consistent performance.

(2) Protects Against Overheating and Safety Risks

When a battery is forced to deliver more than its rated continuous current, it generates excess heat. This can cause the cells to swell, degrade, or in extreme cases, lead to safety hazards.
By knowing both continuous and instantaneous limits, you can design protection systems and select appropriate Battery Management Systems (BMS) to prevent thermal damage and maintain long-term reliability.

(3) Extends Battery Lifespan

Running a battery too close to its maximum discharge limit accelerates aging. The internal chemistry deteriorates faster, leading to reduced capacity and shorter cycle life.
At Shenzhen Himax Electronics Co., Ltd., we use high-quality 18650 and 21700 cells to ensure that our lithium battery packs maintain stable discharge performance even under demanding conditions.

(4) Helps Optimize System Design

Understanding discharge behavior allows engineers to properly size cables, choose suitable connectors, and configure the BMS. It also supports better thermal design, ensuring the system remains cool and efficient during heavy load.
This data is particularly useful for integrators working on custom lithium battery packs for robotics, energy storage, or industrial automation — core areas where Himax specializes.

(5) Duration Time is Just as Important

The time that a battery can sustain its peak current matters. For example, a motor might draw 80A for just a few seconds when starting up, then stabilize at 20A during normal operation.
A high-quality lithium battery from Shenzhen Himax Electronics Co., Ltd. is designed to handle these short bursts of high current without triggering protection circuits or overheating — something that cheaper batteries often struggle with.

3.Summary Table

Parameter	Description	Why It Matters
Continuous Discharge Current	The steady current a battery can safely supply	Ensures reliable performance and safety
Instantaneous Discharge Current	The short-term maximum current for peak loads	Prevents voltage drops during surges
Duration Time	How long peak current can be maintained	Guarantees stability under dynamic conditions

4. Final Thoughts

Understanding the continuous and instantaneous discharge current — and their duration — is not just about technical precision; it’s about safety, reliability, and real-world performance. Whether you’re powering an industrial robot, a smart mobility device, or an energy storage system, choosing the right discharge capability ensures your project operates smoothly and efficiently.

At Shenzhen Himax Electronics Co., Ltd., we design and manufacture high-performance lithium-ion battery packs tailored to each customer’s power requirements.

Why the BMS Can Consume Battery Power and Cause Over-Discharge in a Battery Pack

In every modern lithium-ion battery pack, the Battery Management System (BMS) plays a vital role. It protects the cells, balances voltages, and ensures safe operation.
However, one common issue often overlooked is that the BMS itself can consume power from the battery, and if left unchecked for long periods, this can lead to over-discharge — even when the pack is not in use.

At Shenzhen Himax Electronics Co., Ltd., we often explain this phenomenon to customers who are surprised to find that their battery voltage drops over time despite no external load connected. Understanding why this happens helps prevent premature cell damage and extends battery life.

1. The BMS Always Draws a Small Standby Current

Even when a battery pack is “off,” the BMS remains partially active. It continuously monitors parameters such as:

Cell voltage and temperature

State of charge (SOC)

Balance circuit status

To perform these functions, the BMS consumes a small quiescent current, usually in the range of tens to hundreds of microamps for low-power systems, and sometimes several milliamps in smart BMS designs with Bluetooth, RS485, or UART communication.

Over days or weeks, this constant drain can slowly discharge the cells. If the pack is stored for several months without recharging, the self-consumption current from the BMS alone can push the battery below its safe voltage limit.

2. How BMS Power Consumption Leads to Over-Discharge

(1) Unbalanced Discharge Between Cells

In multi-cell packs, each cell’s voltage can drop slightly differently. The BMS monitors and balances them using small resistors or circuits that bleed current from higher-voltage cells.
During long storage, this balancing current can continue working, drawing more power from specific cells and leading to cell imbalance or deep discharge on some cells.

(2) Continuous Operation of Communication or Protection Circuits

Smart BMS modules — such as those used by Himax — often include communication interfaces (Bluetooth, CAN, UART, etc.). When these functions stay active, they require a small but constant current from the battery.
If the pack is not recharged for a long time, that continuous draw can discharge the pack below 2.5V per cell — a critical point that can permanently damage lithium cells.

(3) Storage Without Periodic Maintenance

If a battery pack is stored for months without being topped up, the combination of BMS self-consumption and natural self-discharge of the cells can cause total pack voltage to fall dangerously low.
Once over-discharged, the cells’ internal chemistry changes — copper dissolves, SEI layers break down — making the pack unstable and unsafe for reuse.

3. Real-World Example

For instance, consider a 14.8V (4S) 20Ah lithium-ion battery pack with a smart BMS that consumes around 1mA in standby mode.
1mA over 90 days equals:
1mA × 24h × 90 ≈ 2.16Ah

That’s roughly 10% of the pack’s capacity lost simply to BMS self-consumption — not counting cell self-discharge. If stored too long, the voltage can easily fall below 3.0V per cell, triggering over-discharge.

4. How to Prevent BMS-Related Over-Discharge

To ensure your battery pack remains healthy during storage or transport, Shenzhen Himax Electronics Co., Ltd. recommends the following practices:

Recharge before storage
Charge the pack to around 50–60% SOC before long-term storage.

Disconnect or switch off the BMS
Some Himax smart BMS models include a sleep or shipping mode that fully disconnects the cells from the control board.

Recharge every 3–6 months
Regular maintenance charging keeps cell voltage above the safe threshold.

Use low self-consumption BMS
Choose a BMS with low quiescent current (<50μA) for applications where long idle time is expected. Himax engineers can help customize such designs.

Monitor remotely (optional)
For smart systems, use remote voltage monitoring to detect early voltage drops before the pack reaches an unsafe level.

5.Summary

Cause	Effect	Solution
BMS standby current	Gradual voltage drop	Use low self-consumption BMS
Continuous balancing	Uneven discharge	Enable auto-sleep or cutoff
Smart features active	Faster drain	Disable communication during storage
Long-term storage	Deep over-discharge	Recharge every few months

Final Thoughts

A BMS is essential for safety, but it is not completely power-free. Without proper maintenance, even a small standby current can slowly drain the battery pack and cause over-discharge damage.

At Shenzhen Himax Electronics Co., Ltd., we design and manufacture lithium battery packs with intelligent, energy-efficient BMS solutions that minimize self-consumption and protect against deep discharge. Our engineering team can help you select the right configuration or customize a smart BMS that matches your application perfectly — from robotics and industrial systems to energy storage and portable equipment.

Why the RS485 Communication BMS Needs to Be Fully Charged to Get an Accurate SOC

In lithium battery systems equipped with RS485 communication BMS, users sometimes notice that the state of charge (SOC) reading is not accurate right after the battery is first assembled or partially charged. The most common question we hear at Shenzhen Himax Electronics Co., Ltd. is:

“Why do I need to fully charge the battery before the BMS can show the correct SOC?”

The answer lies in how the BMS measures and calibrates the SOC — and how the cells inside the battery behave during charging and balancing.

1. Understanding SOC (State of Charge)

The State of Charge (SOC) represents how much energy remains in a battery compared to its full capacity. It’s typically expressed as a percentage:

However, SOC is not directly measurable — it’s an estimated value calculated by the BMS based on voltage, current, and time (known as coulomb counting).

Because of this, the SOC accuracy depends on precise calibration between the battery’s actual capacity and the BMS’s internal calculation.

2. How the RS485 BMS Calculates SOC

A BMS with RS485 communication is designed to collect real-time data from the battery pack — such as:

Total voltage

Current flow (charge/discharge)

Cell voltages and temperatures

Remaining capacity (Ah)

It then communicates these values to the host system, inverter, or display screen.

But when the BMS is first installed or after deep discharge, its internal SOC counter may not match the real battery capacity. The only way for the BMS to “learn” the true full capacity is through a complete charge calibration cycle.

3. Why Full Charging Is Necessary for Accurate SOC

There are three key reasons why full charging allows the BMS to correct and stabilize the SOC reading:

(1) Cell Voltage Balancing

During charging, the BMS equalizes the voltage of each cell through its balancing circuit.
If the cells are not balanced, some may reach their maximum voltage earlier than others, causing the pack voltage to rise unevenly.
A full charge ensures that all cells reach their upper voltage limit (e.g., 4.20V per cell), which provides a clear reference point for the BMS to mark “100% SOC.”

(2) Calibration of Coulomb Counting

The BMS tracks how much current enters or leaves the battery to estimate capacity. Over time, this method accumulates small measurement errors.
A full charge helps the BMS reset or recalibrate the coulomb counter, aligning the calculated capacity with the actual stored energy.

(3) Accurate SOC Synchronization with RS485 Data

When using RS485 communication, the SOC data sent to other devices — such as an inverter, controller, or monitoring system — must match the real battery condition.
A full charge establishes a reliable reference point for 100% SOC, ensuring that the system displays consistent and accurate information across all devices.

4. What Happens If the Battery Is Not Fully Charged

If a lithium battery with an RS485 BMS is not fully charged:

The SOC may drift over time because the BMS cannot confirm its upper voltage reference.

The system may show incorrect SOC readings, such as 85% when the battery is already full or 0% when capacity remains.

In energy storage systems, the inverter may misinterpret SOC, leading to early cutoffs or incomplete charging cycles.

At Shenzhen Himax Electronics Co., Ltd., we’ve seen cases where customers believed their battery capacity was lower than expected — but after a full charge and balance cycle, the SOC corrected itself automatically.

5. How to Perform the Initial Calibration

To ensure accurate SOC readings for RS485 communication BMS packs, follow these steps:

Fully charge the battery until it reaches the rated voltage (e.g., 16.8V for a 4S pack, 29.4V for a 7S pack).

Keep charging for an additional 30–60 minutes to allow cell balancing to complete.

Once the pack is balanced and current drops near zero, the BMS sets that point as 100% SOC.

Afterward, perform a full discharge to the cut-off voltage to help the BMS calibrate the lower limit (0% SOC).

This process ensures the RS485 BMS communicates an accurate and reliable SOC to your monitoring equipment.

6. Final Thoughts

A full charge is not just about topping up energy — it’s about calibration and synchronization. For RS485 communication BMS systems, this step allows the controller to correctly recognize the real capacity of the battery and prevent misleading readings.

At Shenzhen Himax Electronics Co., Ltd., we design our smart lithium battery packs and RS485 BMS systems with advanced balancing and high-accuracy SOC algorithms to minimize drift and improve precision. Still, performing a full charge during the initial setup or after long storage remains an essential step to ensure the most accurate performance data.

Proper calibration guarantees that your system always knows the true energy status of the battery — delivering reliability, safety, and efficiency for every application.

Understanding State of Charge (SOC) in Lithium-Ion Batteries: The Key to Efficient Energy Management

At HIMAX Electronics, we know that effective battery management is essential for ensuring the optimal performance and longevity of lithium-ion batteries. One critical aspect of this management is understanding the State of Charge (SOC), which plays a crucial role in maximizing efficiency and safety across various applications—from electric vehicles (EVs) to energy storage systems and robotics.

In this article, we’ll explain what SOC is, why it matters, and how it impacts the performance of lithium-ion batteries. Whether you’re an engineer, project manager, or consumer, understanding SOC can help you make informed decisions about battery usage, charging, and overall system management.

What is State of Charge (SOC)?

State of Charge (SOC) refers to the current charge level of a lithium-ion battery, expressed as a percentage of the battery’s total capacity. Essentially, SOC tells you how much energy is left in the battery compared to its full capacity:

100% SOC: Battery is fully charged, and it holds its maximum amount of energy.

0% SOC: Battery is fully discharged, and no usable energy remains.

Intermediate SOC values: For example, a 50% SOC indicates the battery is half-charged.

SOC is an essential metric because it helps users understand the remaining capacity of the battery, much like a fuel gauge in a car. This knowledge allows for efficient energy management and prevents overcharging or over-discharging, both of which can damage the battery and reduce its lifespan.

Why is SOC Important for Lithium-Ion Batteries?

SOC plays a crucial role in various aspects of battery performance:

Battery Protection and Safety

The lithium-ion battery chemistry is sensitive to both overcharging and over-discharging. If a battery is charged beyond its rated voltage or discharged too deeply, it could lead to capacity degradation, reduced lifespan, or even dangerous situations like thermal runaway. A precise SOC monitoring system, typically integrated in a Battery Management System (BMS), ensures that the battery operates within safe voltage and charge limits.

Performance Optimization

Lithium-ion batteries tend to perform best when they are not charged to their maximum or fully drained. By monitoring SOC, users can prevent deep discharge and avoid unnecessary charging cycles, which ultimately extends battery life. For example, keeping the SOC between 20% and 80% can help prolong the health of your battery.

Predicting Battery Runtime

In applications like electric vehicles (EVs), solar energy storage systems, or consumer electronics, knowing the SOC helps predict how much time or distance is remaining before recharging is necessary. In EVs, for instance, a fully charged battery means the car can drive its maximum range, while a lower SOC means less range remains before a recharge is needed.

Energy Efficiency

SOC monitoring allows for more efficient charging by ensuring that the battery is neither overcharged nor left too long without a charge. This leads to a better overall energy use and reduces unnecessary wear and tear on the cells, improving the long-term performance of the system.

How is SOC Measured?

Accurately measuring SOC is essential for battery management, and there are several methods used to do so:

Voltage-Based Estimation

SOC is often estimated using the voltage of the battery. Each lithium-ion battery has a predictable voltage range, and by measuring this voltage, the SOC can be approximated. However, this method can be less accurate because voltage is affected by factors such as temperature and the discharge rate.

Coulomb Counting

Coulomb counting is a more accurate method for measuring SOC. It involves tracking the charge and discharge current over time. By integrating the current flow, the BMS can calculate how much energy has been added or removed from the battery. This method is widely used in high-precision applications like electric vehicles.

Impedance Spectroscopy

A more advanced method, impedance spectroscopy, measures the internal resistance (impedance) of the battery to determine SOC. This approach considers various factors such as battery chemistry, temperature, and age, providing a more accurate estimate of SOC.

Hybrid Approaches

Modern Battery Management Systems (BMS) often combine voltage, current, and impedance measurements to give a more precise and reliable SOC reading. These hybrid approaches improve accuracy and account for factors like aging or temperature changes that can affect battery performance.

SOC and Battery Health

While SOC is essential for real-time monitoring, it’s also closely linked to battery health. Keeping the battery’s SOC within a safe range—typically between 20% and 80%—can significantly extend its useful life. Overcharging (charging beyond 100%) or over-discharging (below 0%) can degrade the battery’s capacity and shorten its lifespan.

HIMAX Electronics incorporates advanced SOC monitoring in our Battery Management Systems (BMS), ensuring that your batteries not only perform optimally but also last longer.

SOC in Different Applications

SOC is crucial across various industries where lithium-ion batteries are used:

Electric Vehicles (EVs)

SOC is the most important indicator of the remaining driving range. Accurate SOC readings ensure that drivers can plan trips and charge their vehicles with confidence.

Energy Storage Systems (ESS)

In solar or wind power storage systems, SOC tells you how much stored energy is available for use. It allows users to know when the system needs recharging and when energy is available for consumption.

Consumer Electronics

From smartphones to laptops, knowing the SOC helps users manage device power effectively, ensuring devices last longer and are ready for use when needed.

Robotics and Industrial Applications

SOC monitoring in robotics or power tools ensures consistent power delivery, preventing unexpected shutdowns due to battery depletion.

Conclusion: SOC and Efficient Battery Management

A well-maintained State of Charge (SOC) system is crucial for the optimal performance, safety, and longevity of lithium-ion batteries. By accurately tracking SOC, you can ensure your batteries deliver reliable, efficient power while preventing damage and extending their lifespan.

✅ Advantages:

High energy density → longer run time for given size/weight.

Relatively long cycle life (500–1000+ cycles).

Low self-discharge (~1–2% per month).

Widely available and mature technology.

Stable form factor (especially cylindrical 18650/21700 cells).

❌ Disadvantages:

Thermal runaway risk if punctured or overcharged.

Needs precise BMS protection to ensure safety.

Capacity drops in high temperature or over time.

2. LiPo (Lithium Polymer)

A subset of Li-ion using a gel-like electrolyte, typically found in soft pouch cells.

✅ Advantages:

Very lightweight and thin, excellent for drones, RC, and custom-fit designs.

High discharge rates (C-rate) – great for burst power.

Flexible shapes/sizes available.

❌ Disadvantages:

Less mechanically stable – more prone to swelling and damage.

Shorter cycle life (300–500 cycles) compared to cylindrical Li-ion.

High risk of fire if punctured or improperly charged.

Requires very careful charging (must use a LiPo charger with balance).

3. LiFePO₄ (Lithium Iron Phosphate)

Known for high safety and longevity, commonly used in solar, UPS, and EV applications.

✅ Advantages:

Extremely long cycle life (2000–5000+ cycles).

Very safe – no thermal runaway or fire under normal conditions.

Wide temperature tolerance.

Flat voltage curve → consistent power output.

Environmentally friendlier than cobalt-based cells.

❌ Disadvantages:

Lower energy density (~90–120 Wh/kg) → larger and heavier for same capacity.

More expensive per Wh in some cases (though decreasing).

Lower voltage per cell (3.2 V nominal vs 3.7 V for Li-ion) → may require more cells in series.

Why Proper Handling of LiPo Batteries Can Prevent Dangerous Short Circuits

Lithium Polymer (LiPo) batteries are widely used in consumer electronics, drones, RC vehicles, and portable devices due to their high energy density and lightweight properties. However, improper handling can lead to short circuits, which may cause overheating, fires, or even explosions. As a leading battery manufacturer, Shenzhen Himax Electronics Co., Ltd. emphasizes the importance of safe LiPo battery usage to prevent accidents. This article explores the causes of short circuits and provides practical guidelines to mitigate risks.

What Causes a LiPo Battery Short Circuit?

A short circuit occurs when the positive and negative terminals of a battery are directly connected with little to no resistance, causing excessive current flow. Key causes include:

Damaged Battery Wrapping – Physical damage to the outer insulation can expose internal electrodes, leading to accidental contact with conductive materials.

Improper Storage – Storing LiPo batteries near metal objects (e.g., keys, coins) increases the risk of terminal contact.

Faulty Wiring or Charging – Using damaged cables or incorrect chargers may create unintended electrical paths.

Punctures or Crushing – Mechanical stress can breach the battery’s internal layers, causing a direct short.

How to Prevent LiPo Battery Short Circuits

1. Inspect Batteries Regularly

Before use, check for:

Swelling or leaks – A bloated LiPo battery indicates internal damage and should be disposed of properly.

Torn Wrapping – Replace damaged insulation immediately with high-quality heat-shrink tubing.

2. Store Batteries Safely

Use non-conductive storage bags or fireproof containers.

Keep terminals protected with insulating caps or tape.

Avoid extreme temperatures and humid environments.

3. Handle with Care During Charging

Always use a LiPo-compatible charger with balance charging functionality.

Never leave charging batteries unattended.

Place batteries on a non-flammable surface (e.g., ceramic tile).

4. Avoid Physical Damage

Do not puncture, bend, or crush LiPo batteries.

Transport batteries in cushioned cases to prevent impacts.

5. Proper Disposal

Discharge depleted LiPo batteries fully before recycling.

Follow local regulations for hazardous waste disposal.

Industry Standards and Himax’s Commitment

At Shenzhen Himax Electronics Co., Ltd., we adhere to international safety standards (UN38.3) to ensure our LiPo batteries meet rigorous testing for short-circuit prevention. Our products feature:

Multi-layered separators to reduce internal short risks.

Robust PVC wrapping for enhanced puncture resistance.

Built-in protection circuits (for select models) to mitigate overcurrent.

Conclusion

Short circuits in LiPo batteries are preventable with proper handling, storage, and charging practices. By following these guidelines, users can maximize both safety and battery performance. Shenzhen Himax Electronics Co., Ltd. remains dedicated to advancing LiPo battery technology while promoting responsible usage worldwide.
