Battery BMS

BMS (Battery Management System) is designed to handle superior abuse tolerance. Smart Battery Lithium Batteries are dual purpose for starting or deep cycle applications and can be connected in series or in parallel. The BMS maximizes the performance of the battery by automatically balancing the cells and protecting them from being over-charged or over-discharged. Our integrated BMS design is what allows our batteries to be used as a drop-in replacement for any application requiring high quality, dependable, and lightweight Lithium Batteries.

FAQs about BMS

HIMAX professional battery manufacturer, reminds us that the battery management system (BMS) is designed to protect battery safety. Battery management systems usually include control ICs, MOS switches, resistors, capacitors and some auxiliary devices. The control IC controls the MOS switch to connect the battery core to the external circuit when everything is normal. When the battery core voltage or loop current exceeds the specified value, it immediately controls the MOS switch to turn off to protect the battery core safety.
Battery management systems (BMS) are widely used in electric vehicles, new energy power stations, solar photovoltaics, and aerospace. In addition, battery management systems are also widely used in power systems, communication equipment, medical equipment, power tools, and electric power supplies. Bicycles, electric vacuum cleaners, lawn mowers, small household appliances and many other fields.

HIMAX professional battery manufacturer, reminds us that the battery management system plays a vital role in battery applications. The BMS has four major functions: overcharge, over-discharge, over-current, and reverse connection protection (short circuit protection).

  1. Overcharge protection function: When a certain voltage is reached, the charger is prohibited from continuing to charge. The MOS tube that controls overcharge enters a shutdown state and stops charging.
  2. Over-discharge protection function: When the battery output voltage becomes low, it stops discharging the load. The MOS tube that controls over-discharge enters a shutdown state and prohibits discharge. This process is exactly the opposite of the action during overcharge detection.
  3. Overcurrent protection function: Stop discharging the load when a large current is detected, effectively protecting the battery and MOS tube and ensuring the safety of the battery in the discharge state. After over-current detection, the battery will return to normal after being separated from the load and can be charged or discharged.
  4. Short circuit protection function: When the maximum allowed output current is exceeded, the MOS tube that controls over-discharge enters shutdown and cuts off the discharge circuit of the battery core to ensure the safety of the battery and electrical appliances.
  5. In addition, HINAX BMS also supports thermal management and communication functions.
Common battery management system faults mainly include communication faults, data acquisition faults, battery parameter abnormalities, battery balancing faults, thermal management faults, relay faults, system power supply faults, etc. Different faults correspond to different solutions; at the same time, regular maintenance and upkeep of The BMS system is also an important measure to prevent failures.
HIMAX is Asia’s leading battery manufacturer. It provides a series of battery pack charger solutions, including lithium-ion battery pack BMS, lithium polymer battery pack BMS, lithium iron phosphate battery pack BMS, etc. Not all batteries currently on the market come with protective plates;
Therefore, when purchasing batteries, it is best to choose a professional battery manufacturer (such as HIMAX), which can help you extend the service life of the battery and effectively avoid risks.
The future of battery management systems looks quite broad and positive. With the rapid development of new energy vehicles and power battery industries, technological innovation promoting battery management system functional diversification, intelligence and adaptive control as a development trend, and the application of big data analysis in BMS, the battery management system industry will usher in a new era. many development opportunities and challenges. At the same time, policy support will also provide a strong guarantee for the development of the battery management system industry.
When purchasing a battery management system, you need to pay attention to the following aspects to ensure that you choose a system that suits your needs, such as battery type, number of batteries in series, whether the battery pack charging port is the same port or separate ports, and the location of the protective board. Required current value, brand and after-sales service, legal and compliance, etc. As a professional battery manufacturer, HIMAX provides customized battery management system solutions.
