Home About Us EVENTS & NEWS Top 10 Battery Management System Companies in China: Choosing the Right BMS Supplier for You
Every contemporary rechargeable battery pack is built around a Battery Management System (BMS), which makes sure the battery runs safely and effectively. A BMS serves as the “brain” of the battery in applications such robots, drones, energy storage systems (ESS), electric vehicles (EVs), medical equipment, and golf carts.
Its primary functions include:
Monitoring: Tracks voltage, current, temperature, and state of charge (SOC).
Protection: Prevents overcharge, over-discharge, short circuits, and thermal runaway.
Balancing: Ensures each cell within a pack is equalized to maximize performance and lifespan.
Communication: Provides real-time data to controllers or external systems via CAN-Bus, SMBus, or Bluetooth.
Thermal Management: Regulates battery temperature to avoid overheating or degradation.
