Diagnostic tips
1
Verify charger output voltage and current before connecting to the battery.
2
Confirm CAN compatibility with the vehicle BMS before enabling CAN charging.
3
Verify CAN baud rate and CAN message configuration.
4
Monitor battery SOC, temperature and charging limits through CAN.
5
Check charger cooling and ventilation.
6
Inspect AC input and DC output connectors for heating or damage.
7
Use appropriate over-voltage, over-current and short-circuit protection.
