FAQs about BMS

As a professional battery manufacturer, Himax Electronics emphasizes that the Battery Management System (BMS) is fundamentally designed to safeguard battery safety and optimize performance. A typical BMS circuit integrates control ICs, MOS switches, resistors, capacitors, and various auxiliary components. This sophisticated system continuously monitors the battery, ensuring that its cells operate within safe parameters. When cell voltage or current deviates from specified values, the BMS intelligently controls the MOS switch to disconnect the battery core from the external circuit, providing immediate and effective battery protection.
  • Electric Vehicles (EVs) & E-mobility: Essential for safe and efficient operation of EV battery packs, optimizing range and lifespan.
  • New Energy Power Stations & Renewable Energy Storage: Vital for the stability and longevity of large-scale battery energy storage systems in solar, wind, and microgrid applications.
  • Solar Photovoltaic Systems: Ensuring efficient charging, discharging, and protection of solar battery banks.
  • Aerospace & Defense: Providing robust and reliable battery protection for high-stakes applications.
  • Power Systems & Communication Equipment: Guaranteeing uninterrupted power supply and protecting critical infrastructure.
  • Medical Equipment & Portable Medical Devices: Delivering precision battery management for sensitive applications where reliability is non-negotiable.
  • Power Tools & Industrial Equipment: Extending the life and enhancing the safety of high-power battery packs.
  • Electric Bicycles, Electric Vacuum Cleaners, Lawn Mowers, Small Household Appliances: Enabling safer, more efficient, and longer-lasting operation of consumer and commercial products.

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.
