Charge Connector Lock Actuator

Component Description

FUNCTIONS WITHIN THE SYSTEM

Charge connector lock actuator locks charge connector by lock pin, when charge connector is connected to normal charge port during normal charge. Refer to System Description.

INDIVIDUAL OPERATION

The charge connector is locked by inserting a lock pin of the charge connector lock actuator into the tip of normal charge connector.

Operation

Lock pin is operated to Lock/Unlock position by operation request signal from VCM.

PARTS LOCATION

Charge connector lock actuator is installed to top of charge port.

Refer to Specifications.

Charge Port

Component Description

FUNCTIONS WITHIN THE SYSTEM

The quick charge port is installed to the side of vehicle. At normal charge, it connects EVSE (charge cable) or mode 3 cable charge connector to send high voltage current to the on-board charger. At quick charge, it connects the connector of the quick charger and send high voltage current to the high voltage battery.

INDIVIDUAL OPERATION

The charge port is installed to the side of vehicle. At normal charge, it connects EVSE (charge cable) or mode 3 cable charge connector to send high voltage current to the on-board charger. At quick charge, it connects the connector of the quick charger and send high voltage current to the high voltage battery.

Refer to Specifications.

Charge Port Light

Component Description

FUNCTIONS WITHIN THE SYSTEM

The charge port light lights up inside in charge port lid to support the charge connector connection.

INDIVIDUAL OPERATION

Operation

Charge port light is turned ON/OFF based on signal from VCM

PARTS LOCATION

Charge port light is installed into charge port lid.

Refer to Specifications.

Charging Status Indicator

Component Description

FUNCTIONS WITHIN THE SYSTEM

Charging status indicator changing one indicator into 3 colors to display charge status of the Li-ion battery.

	: Charging status indicator
	: Nissan Ariya Vehicle front

INDIVIDUAL OPERATION

Charging station communication module turns ON/OFF/ BLINK according to control signal from VCM.

Operation

Charging status indicator is operated as follows;

PARTS LOCATION

Charge status indicator is installed to upper side of instrument panel.

Refer to Specifications.

Cplc

Component Description

FUNCTIONS WITHIN THE SYSTEM

CPLC converts signals of quick charge communication between charger and vehicle.

INDIVIDUAL OPERATION

CPLC is ECU that converts signals of quick charge communication between charger and vehicle during quick charge.

Operation

CPLC is ECU that converts signals of quick charge communication between charger and vehicle during quick charge via CAN communication.

PARTS LOCATION

CPLC is installed to under front floor spacer near passenger foot.

Dc/dc Converter

Component Description

FUNCTIONS WITHIN THE SYSTEM

• High DC voltage from Li-ion battery is stepped down to DC 14 V approximately to charge 12V battery.

• Output voltage is changed by the signal from VCM to supply the optimum voltage for Nissan Ariya vehicle condition.

INDIVIDUAL OPERATION

DC/DC converter steps down power from Li-ion battery to optimum voltage to supply power to vehicle.

Operation

High DC voltage of Li-ion battery is stteped down to DC 14 V approximately

PARTS LOCATION

DC/DC converter is installed under high voltage supply unit in motor room.

High Voltage Junction Box

Component Description

FUNCTIONS WITHIN THE SYSTEM

High voltage junction box distributes high voltage power supply to each component parts, and has a built-in temperature sensor to transmit signal to VCM

INDIVIDUAL OPERATION

High voltage junction box sends high voltage power supply from Li-ion batter to the connected high voltage component parts such as DC/DC converter, electric compressor, etc..

Operation

High voltage power supply from Li-ion battery is distributed.

PARTS LOCATION

High voltage junction box is installed to high voltage supply unit ASSY on the left side of vehicle in the motor room.

High Voltage Warning Label

Component Description

PARTS LOCATION

High voltage warning label is attached to upper front of high voltage junction box.

：Nissan Ariya Vehicle front

CAUTION:

When replacing high voltage junction box, attach the label to original position.

Immediate Charging Switch

Component Description

FUNCTIONS WITHIN THE SYSTEM

Charge can start immediately by operating immediate charging switch when timer charge is set.

INDIVIDUAL FUNCTIONS WITHIN THE SYSTEM

The switch inputs immediate charging switch status to VCM.

INDIVIDUAL OPERATION

Momentary switch is adopted, and voltage is changed to 0 V and 5 V by turning the switch ON and OFF.

VCM reads the switch status according to potential change.

NOTE:

Momentary switch: Turns ON only while switch is pressed, and returns to normal OFF state when switch is released.

PARTS LOCATION

Immediate charging switch is installed to instrument lower panel.

Refer to Specifications.

On-Board Charger

Component Description

FUNCTIONS WITHIN THE SYSTEM

On-board charger converts external AC power supply to DC power supply (300 V- 430 V) and charges Li-ion battery.

INDIVIDUAL OPERATION

PFC circuit is adopted for on-board charger to improve charge efficiency and amount of charge, and to extend life of Li-ion battery.

NOTE:

PFC (Power Factor Correction) circuit is power factor improvement circuit, which is a device that efficiently converts AC power input from an external power supply to DC power supply.

Operation

1. AC power input from external power supply is rectified to DC power supply by rectifier circuit 1.

2. Rectified DC power supply is boosted at the same time as the power factor is improved by PFC circuit.

3. Boosted DC power supply is converted to AC power supply again by inverter.

4. AC power supply from inverter is converted voltage by insulated transformer and rectified to high voltage DC power by rectifier circuit 2.

5. Rectified high voltage DC power is output from output circuit.

PARTS LOCATION

On-board charger is installed above the traction motor in the motor room as high voltage supply unit assembly.

Refer to Specifications.
