Basic Control

When VCM judges that the system is in a charge mode, VCM activates the F/S relay and M/C relay to allow charging operation.

Then, VCM determine the charge power based on the Li-ion battery chargeable power signal received from the Li-ion battery controller and the on-board charger chargeable power signal received from the on-board charger, and then VCM sends the maximum charge power signal to the on-board charger.

The on-board charger determines a charge power based on the maximum charge power signal and the maximum input current signal sent by the EVSE control box.

Concurrently, the on-board charger activates the normal charge relay and VCM activates the system main relay 1 and system main relay 2. Consequently Li-ion battery charge starts.
