INPUT/OUTPUT SIGNAL TABLE







BASIC CONTROL

When EVSE is connected under the power switch OFF condition, VCM judges that the system is in a charge mode and activates the F/S relay and M/C relay to allow charging operation.
Then, VCM determines 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. VCM then 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.
NOTE:
Li-ion battery charge does not start when the power switch is ON. When it is required to charge with the power switch ON, start charging before turning ON the power switch.

IMMEDIATE CHARGE MODE

When EVSE is connected to the normal charge port, the on-board charger transmits an EV system activation signal to VCM. Li-ion battery charge then starts immediately.
When the timer charge is set, Li-ion battery charge does not start just after the on-board charger transmits an
EV system activation signal to VCM. When VCM detects an ON signal from the immediate charging switch in that state, VCM judges that the immediate charge mode is selected and starts charging.
When the charge is finished and VCM receives a Li-ion battery charge completion signal from Li-ion battery controller, VCM stops the charge control.

TIMER CHARGE MODE

VCM starts up automatically and starts charging at the set time.
When VCM receives a Li-ion battery charge completion signal from Li-ion battery controller or at a set timer charge finish time, VCM stops the charge control.
NOTE:
When timer charge and the timer air conditioner operate simultaneously, VCM distributes power to the air conditioner system and the charge system according to the priority set on the navigation screen.

REMOTE CHARGE MODE

When TCU transmits an EV system activation signal to VCM, VCM judges that the remote charge mode is selected and starts charge control.
When VCM receives a Li-ion battery charge completion signal from Li-ion battery controller, VCM stops the charge control.

CANCEL CONDITIONS

VCM stops the normal charging when VCM detects the EVSE is disconnected.
In addition, under the following conditions, VCM temporarily stops the normal charging and enters standby status.
- When the AC voltage and PWM communication from the EVSE are interrupted.
- When the EVSE connector release switch is pressed.
- When the Li-ion battery temperature reaches 60�C (140�F) or higher.
