Basic Control
When the quick charge connector is connected to the quick charge port and the start switch of quick charger is pressed, the PDM (Power Delivery Module) transmits an EV system activation request signal to VCM. VCM then activates the F/S CHG relay.
Next, VCM determines the target charge power based on the Li-ion battery chargeable power signal received from the Li-ion battery controller and the chargeable power signal received from the PDM (Power Delivery Module). VCM then sends the maximum charge power signal to the PDM (Power Delivery Module).
The PDM (Power Delivery Module) converts the Maximum charge power signal to a charge current request signal and transmits it to the quick charger.
Simultaneously, the PDM (Power Delivery Module) activates the quick charge relay, and VCM activates system main relay 1 and system main relay 2. Consequently, the quick charge starts.
When the charge amount reaches the prescribed amount and VCM receives the Li-ion battery charge completion signal from the Li-ion battery controller, VCM stops the charging.
- Even if the Li-ion battery remaining energy does not reach the predetermined level, VCM may stop the charge control after a certain period of time.
- When the Li-ion battery temperature reaches 60°C (140°F) or higher, VCM temporarily stops quick charging and enters standby status.
