High-voltage box
High-voltage box is the unit of energy distribution, control and communication exchange of the battery system, realizing the functions of energy distribution, switching control, overload protection and signal exchange between the power battery and the whole vehicle and charging equipment.
BMS
Battery Safety Management
Over-charging/over-discharging protection, over-current/ over-temperature/ low-temperature protection, multi-level troubleshooting protection, double fault monitoring.
SOC/SOH Detection
Remaining capacity estimation, battery health estimation, high precision capacity integration.
Balanced Management
Equalization based on voltage mode, time mode, cell SOC, active/passive equalization optional.
High Voltage Safety Management
High voltage interlock, high voltage insulation monitoring, high voltage switch diagnosis.
Battery Parameter Detection
Battery voltage detection and analysis, battery current detection and analysis, battery temperature detection and analysis.
Other Features
Low cost, low power consumption, historical data recording, cascading flexible expansion, CRC data verification.
Thermal Management
For different ambient temperature regions, thermal management strategies are as follows:
≤5℃，start heating
<30℃ ，dormant state
≥30℃ ，self-circulation (start the pump, shut down the cooling)
≥35℃ ，running cooling
