Why “Overcharged-Low Discharge” and “Undercharged-High Discharge” Happen in Lithium Battery Packs

high-quality-18650-battery-holder-materials

In the real-world application of lithium-ion battery packs, performance issues like overcharged-low discharge and undercharged-high discharge are common causes of customer complaints. These phenomena can severely impact the performance evaluation, safety, and overall user experience of battery systems.

This article aims to break down these two issues in simple, professional terms — explaining their symptoms, root causes, potential risks, and possible solutions. Whether you’re a battery designer, manufacturer, or end-user, this guide can help you better understand and manage these challenges.

1. The Overcharged-Low Discharge Issue: Hidden Capacity Loss and Safety Risks

What Is Overcharged-Low Discharge?

The term overcharged-low discharge refers to a mismatch between the battery pack’s charging and discharging capacity. For example, a pack rated at 100Ah may appear to charge up to 105Ah, but during discharge, it only delivers 95Ah. This leads to confusion about the battery’s actual capacity and performance.

What Causes It?

There are several technical reasons behind this issue:

Inconsistent Cell Aging: In a multi-cell battery pack, not all cells age at the same rate. Some cells degrade faster due to manufacturing differences or usage conditions. During charging, weaker cells reach their maximum voltage sooner, causing the Battery Management System (BMS) to halt charging to prevent overcharging — even though other cells are not fully charged. During discharge, these weaker cells also drop voltage faster, again prompting the BMS to stop discharging early.

Internal Resistance Differences: Cells with higher internal resistance show a faster voltage rise during charging and a quicker drop during discharging. This leads to misleading voltage readings that cause early cutoffs by the BMS.

Uneven Temperature Distribution: Cells operating in cooler areas of the pack show reduced electrochemical activity, which limits their ability to charge or discharge fully. These cells become bottlenecks, reducing the usable capacity of the entire pack.

What Are the Risks?

Misleading Capacity Indications: Users may believe the battery has more capacity than it can safely deliver.

Accelerated Aging: Cells that are frequently undercharged or prematurely stopped during charge/discharge cycles age more quickly.

Safety Hazards: In extreme cases, deep discharge of weak cells can lead to lithium plating or thermal runaway — a dangerous safety concern.

2. The Undercharged-High Discharge Issue: Algorithm Errors and Temperature Effects

What Is Undercharged-High Discharge?

This is a phenomenon where a battery appears to charge less than its rated capacity but releases more during discharge. For instance, it might charge to 95Ah but discharge 98Ah. This seems counterintuitive but is observed in many battery pack applications.

What Causes It?

BMS Calibration Errors: The BMS may inaccurately estimate the battery’s state of charge (SOC), leading to an early stop during charging or extended discharging.

Low-Temperature Charging: In cold environments, lithium-ion mobility is reduced, decreasing charge acceptance. However, when the temperature rises during discharging, the cells can perform normally, appearing to release more energy than they received.

Balancing Circuit Interference: During charging, passive balancing circuits may drain energy from higher-voltage cells to equalize the pack, lowering the total reported charge.

What Are the Risks?

Unnecessary Service Complaints: Users may believe the battery did not charge properly and request service or replacement.

Over-Discharge Risk: The battery may discharge below safe limits due to inaccurate SOC readings.

Structural Damage to Electrodes: Repeated over-discharge or undercharge can degrade the internal structure of the battery cells, shortening lifespan.

3. The Root Cause: Inconsistency Among Cells

At the core of both problems is one major factor: cell inconsistency. Variations between individual cells lead to imbalances during both charging and discharging. These inconsistencies stem from three main areas:

Manufacturing Variability: Even small differences in electrode coating thickness or electrolyte saturation can result in performance variation between cells.

Uneven Usage Conditions: Non-uniform heat distribution, differing current paths, and environmental conditions cause individual cells to age at different rates.

Diverging Aging Speeds: Some cells may deteriorate faster due to localized overheating, repeated overcharge/discharge cycles, or physical stress.

4. Effective Solutions: From Design to Intelligent Management

Addressing these problems requires a multi-pronged strategy from the initial cell selection to long-term system management.

Cell Grading and Grouping

Before assembling the pack, cells should be sorted based on their capacity, internal resistance, and self-discharge rate. Grouping closely matched cells reduces imbalance and improves the performance of the entire pack.

Advanced Balancing Technologies

Active Balancing: Transfers energy from higher-voltage cells to lower-voltage ones using inductors or capacitors. This improves pack efficiency but increases system complexity and cost.

Passive Balancing: Uses resistors to bleed excess energy from stronger cells. While simpler and cheaper, it wastes energy and is less efficient.

Smarter BMS Algorithms

Combine Coulomb Counting (Ah integration) with Open Circuit Voltage (OCV) methods for more accurate SOC estimations.

Monitor individual cell voltages and temperatures in real time, and trigger balancing actions if the voltage gap exceeds set thresholds (e.g., >0.3V).

Better Thermal Management

Use liquid cooling or forced air systems to maintain a uniform temperature across all cells.

Avoid localized hotspots or cold zones that can accelerate aging or reduce performance.

5. Conclusion: Focus on Consistency, Intelligence, and Control

The overcharged-low discharge scenario often indicates the presence of weak cells that limit the overall capacity and raise safety concerns. The undercharged-high discharge issue is usually linked to BMS miscalibration or environmental factors like low temperature.

Ultimately, both issues can be traced back to inconsistencies between individual cells. The best long-term solution lies in:

Careful matching of cells at the factory,

Applying dynamic balancing methods, and

Employing smart BMS algorithms with real-time monitoring.

As lithium-ion battery packs technologies evolve, advanced sorting equipment, AI-powered BMS systems, and efficient thermal designs will become key tools in minimizing these customer complaints and maximizing battery performance.

By implementing these strategies, manufacturers can build safer, longer-lasting, and more reliable lithium-ion battery packs — delivering real value to customers in today’s increasingly electrified world.

Can a Lithium Ion Battery Cell Be Reused After an Internal Short Circuit If It Passes Retesting?

high energy density lithium ion battery pack

During lithium ion battery manufacturing, internal short circuits in cells are a critical and potentially hazardous issue. In some cases, a shorted cell may later appear “normal” during retesting—for example, the voltage may recover, and no abnormal heat is detected. This leads many engineers to ask: Can a li-ion battery cell that once experienced an internal short circuit be reused if it passes retesting?

This article provides a detailed technical analysis and gives a clear conclusion:
Reusing such cells is strongly discouraged. Even if retesting results appear normal, the cell must be scrapped.

1. Hidden and Recurrent Risks of Internal Short Circuits

Internal short circuits are typically caused by:

Metallic contaminants such as copper or aluminum particles;
Burrs on electrode edges piercing the separator;
Minor damage or thermal shrinkage of the separator.

These types of defects can be difficult to detect and may recur unpredictably. For example:

Metal particlesmay initially cause a short and then melt due to localized heat, seemingly “resolving” the problem. However, they can remain in the cell and trigger a short again later.
Copper debrismay lead to a cycle of melting and re-connection, resulting in intermittent short circuits.
Burr-induced shortsmay not be detected under low current testing but can reappear during high-rate charge/discharge cycles.

2. Irreversible Material Damage From Short Circuits

Even if the cell voltage returns to normal, the internal structure may already be compromised:

High temperatures at the short circuit site may melt the separator, enlarging pores or causing internal leakage;
Decomposition of active materials or conductive additivesmay occur;
These conditions accelerate side reactions, reducing capacity and increasing risk of failure.

Studies show that even after retesting, such cells may have near-normal capacity but significantly reduced coulombic efficiency (e.g., 99.3% vs. 99.9% in normal cells), indicating that side reactions are still active. This leads to faster degradation and higher thermal risk over time.

3. Limitations of Standard Li-ion Battery Cell Testing Methods

Common testing methods used in lithium battery production have clear limitations when detecting micro short circuits:

Hi-Pot (high-voltage insulation) testsare not sensitive enough to detect tiny conductive particles;
OCV (Open Circuit Voltage) monitoringand self-discharge (K value) tests cannot identify very low leakage currents;
Temperature rise monitoringmay fail to detect localized heating or increased internal resistance during short test durations.

Therefore, even if a cell passes all routine tests, its safety cannot be guaranteed.

4. Recommendations and Preventive Measures

1. All Cells With Any Short Circuit History Must Be Scrapped

Regardless of retest results, any cell that has experienced an internal short circuit must be classified as a non-conforming product and scrapped immediately. Continuing to use such cells may result in sudden failures in the field or act as a “weak link” in a battery pack, triggering systemic risks.

2. Process Optimization to Prevent Internal Short Circuits

Strengthen material cleanliness control to prevent contamination;
Optimize slitting, winding, or stacking processes to minimize burrs;
Use high-strength, thermally stable separator materials;
Introduce advanced detection technologies, such as X-ray inspection or micro-current leakage detection.

5. Conclusion: Prioritize Safety, Eliminate Risk at the Source

Lithium batteries are high-energy devices. Any potential defect poses a serious safety hazard. Even if a cell appears normal after an internal short circuit, the underlying risk remains. Eliminating such cells from the production line is the only responsible action.

True product safety and reliability come not from relying on retests, but from improving production processes and early-stage quality control.

Understanding the 14.8V Lithium Battery: Technology and Robotics Applications

How Does a 14.8V Lithium Battery Work?

A 14.8V lithium battery is a rechargeable power source based on lithium-ion technology. Its core mechanism involves the movement of lithium ions between the positive and negative electrodes to store and release energy. Typically, these batteries are made up of multiple single cells connected in series. Each cell has a nominal voltage of 3.7V, so a 14.8V battery consists of four cells (known as a 4S configuration). This voltage level is perfectly suited for the power and endurance needs of robots, providing a steady energy output.

The positive electrode in lithium batteries is often made of materials like lithium iron phosphate or ternary compounds, while the negative electrode is usually graphite. An electrolyte facilitates the movement of lithium ions. During discharge, lithium ions travel from the negative to the positive electrode, generating a current; during charging, the ions move in the opposite direction.
