Battery Management System
What is a Battery Management System?
The battery management system (BMS) monitors and controls battery performance, ensuring that the battery operates within safe limits.
It monitors numerous parameters of each cell, preventing damage to the battery pack.
The BMS ensures a balanced charge, significantly extending battery life.
Its scalability and reliability make it an essential component of any energy storage architecture.
Features
The BMS monitors and controls various battery types in different applications to ensure a constant power supply and optimal battery health.
- Measurement:
Voltage, current, and temperature of each cell - Protection against:
Short circuit, overcharging, deep discharge, overheating - Monitoring:
State of charge (SOC), state of health (SOH) - Charging mode: Cell balancing
- Communication: CAN FD, LIN, I²C, or UART
Applications
- Combustion engine vehicles: Control of 12V or 24V lithium batteries
- Battery electric vehicles and Plug-in hybrids (BEVs/PHEVs): Control of low-voltage auxiliary batteries and high-voltage traction batteries (400V/800V)
- Renewable energy storage systems
- Aviation applications such as eVTOLs and air taxis
