How does a BMS protect a battery pack?
Monitoring battery pack current and cell or module voltages is the road to electrical protection. The electrical SOA of any battery cell is bound by current and voltage. Figure 1 illustrates a typical lithium-ion cell SOA, and a well-designed BMS will protect the pack by preventing operation outside the manufacturer’s cell ratings.
How does a battery management system (BMS) work?
A battery management system (BMS) monitors the cell voltage of each cell group. If any of them go lower than a certain threshold (usually around 2.6 volts), the BMS disconnects the cells to prevent damage. During charging, a high voltage is applied across many sets of lithium-ion cells in series.
What is a battery balancing system (BMS)?
By identifying and mitigating unsafe operating conditions, the BMS ensures the safe operation of the battery pack and the connected device. It prevents overcharging, over discharging, and thermal runaway. To maintain uniformity across individual cells, the BMS incorporates a cell balancing function.
Why do lithium batteries need a BMS?
Overcharging or discharging a lithium-ion battery can shorten its life and even cause safety hazards. A BMS prevents this by automatically disconnecting the battery from the charger or load when it reaches unsafe levels, safeguarding the battery and preventing potential damage.
What does BMS mean in a battery?
At its core, BMS stands for Battery Management System. It's an essential component for lithium-ion batteries, which are commonly used in electric vehicles (EVs), energy storage systems (ESS), and other devices that require rechargeable batteries.
What is a battery management system?
A battery management system is a high-voltage PCBA with various components mounted on it. It acts as the brain of the lithium-ion battery pack for EVs, solar energy systems, etc. If you want battery management systems for your custom battery packs, contact the one-stop BMS manufacturer PCBONLINE by email or from the online chat window.
