6 FAQs about [BMS protects the battery]

Why do you need a battery management system (BMS)?

With a well-designed BMS, your battery is equipped with comprehensive protection against various risks. The BMS’s ability to prevent overcharging, detect short circuits, manage temperature, protect against over-discharge, and balance cells ensures that the battery operates safely and efficiently.

What is a battery monitoring system (BMS)?

Battery Monitoring: One of the primary functions of a BMS is to monitor the voltage and current of each individual cell within a battery pack. By continuously monitoring these parameters, the BMS can determine the state of charge and state of health of the battery and provide accurate information to the user or the control system.

Why is BMS important in electric vehicles?

Electric Vehicles: BMS plays a critical role in electric vehicles by ensuring the safe and efficient operation of the battery packs. It monitors the state of charge, temperature, and performance of the battery to maximize the driving range and lifespan of the battery.

What is an electric vehicle battery management system (BMS)?

An electric vehicle battery management system (BMS) is a system that monitors, manages, and regulates the charging and discharging of a lithium-ion battery pack in an electric vehicle.

What types of current protection does a BMS offer?

The BMS offers two connected types of current protection: overcurrent and short-circuit protection. Immediate current monitoring helps the system detect problems before they become dangerous situations. The system’s overcurrent protection watches current flow and triggers protective measures when it exceeds thresholds.

How can a BMS prevent a lithium ion battery failure?

The BMS must cut off the battery instantly to prevent catastrophic failures. The number of MOSFETs needs proper sizing based on potential short-circuit current. One pair of FETs might fail, but four pairs can effectively stop dangerous current flow. Thermal runaway is one of the most dangerous ways lithium-ion systems can fail.
