Normal Charge Control

System Description

System Diagram

BASIC CONTROL

When EVSE is connected at power switch OFF status, EVSE connection signal is transmitted to VCM. VCM that receives the signal determines as charging mode. VCM also determines the maximum charge power based on the Li-ion battery chargeable power signal received from LBC, the chargeable power signal received from on-board charger, and the maximum current request signal received from EVSE, and transmits the charge current command value to on-board charger determines the charge power based on charge current command value. VCM starts charge by turning ON the system main relays 1 and 2.

NOTE:

When shift position is except P range during READY status and charge connector is connected to charge port, READY is turned OFF and power switch is turned ON and then shift position is N range.

NORMAL CHARGE MODE

This mode performs charging by connecting EVSE (charge cable). Normal charge includes immediate charge mode, timer charge mode, and remote charge mode.

IMMEDIATE CHARGE MODE

This mode performs immediate charge as soon as EVSE is connected. If timer charge is not set, enter charge mode as soon as EVSE is connected. If timer charge is set, immediate charge mode is selected by pressing immediate charge switch.

• When EVSE connection signal is transmitted to VCM, VCM judges that EVSE is connected and turns on-board charger ON to start charge immediately.

• If timer is set, even when EVSE connection signal is transmitted to VCM, charge is not started immediately. If VCM detects immediate charge switch ON signal in this state, VCM judges as immediate charge mode and starts charge.

• When the charge reaches specified amount and VCM receives Li-ion battery charge completion signal from LBC, VCM stops charge.

• When pressing immediate charge switch, immediate charge is performed for 15 minutes. this mode does not reset even if charge connector is unplugged. To return to timer charge after pressing immediate charge switch, press immediate charge switch again during connecting charged connector.

TIMER MODE

BCM starts up automatically and starts charging at the set time.

NOTE:

Timer can be changed by "Timer charge" and "Timer charge at home/Timer charge 1/Timer charge 2/Timer charge 3"of navigation system.

REMOTE CHARGE MODE

This mode starts the charge by remote control with mobile tool.

NOTE:

For operation, Refer to System Description.

• When BCM transmits EV system activation request signal to VCM via CAN communication, VCM judges that remote charge mode is selected and starts charge.

• When VCM receives Li-ion battery charge completion signal from LBC, VCM stops charge.

CANCEL CONDITIONS

VCM stops normal charge control when VCM detects that EVSE is disconnected.

In addition, when the following conditions are satisfied, VCM pauses normal charge and enters standby status.

• When communication from EVSE and AC voltage are interrupted.

• When EVSE connector release switch is ON.

BASIC CONTROL

When quick charge connector is connected to quick charge port and start switch of quick charger is pressed, VCM detects start switch ON by quick charger start/stop signal 1. And then VCM activates F/S CHG relay, system main relay 1, system main relay 2 and quick charge relay to be ready for the quick charge.

—Next, VCM determines charge current request value based on Li-ion battery chargeable power signal received from LBC and quick charger output possible current signal received from quick charger.

Quick charger controls output power according to charge current request signal received from VCM.

When the charge amount reaches the specified amount and VCM receives Li-ion battery charge completion signal from LBC, VCM stops charge.

NOTE:

• Even if Li-ion battery charge level does not reach target level, VCM may stop charge after a certain period of time.

• When Li-ion battery temperature reaches specified temperature or higher, VCM pauses quick charge and enters standby status.

• Charge does not start at power switch ON. If charge is required while power switch is ON, turn power switch OFF and charge starts and then power switch is ON.

QUICK CHARGE MODE

This mode performs charging with quick charger. Even if charge is not completed, when the charge time set on the quick charger or the time-out (maximum 255 minutes) set on Nissan Ariya vehicle passes, charge is stopped.

NOTE:

• When the battery temperature is low or high, charge is stopped after 255 minutes maximum.

• If charge stopped before charge is completed, additional charge by quick charge can be performed again.
