Charge Connector Lock/Unlock Control

Control Outline

The VCM judges the lock operation conditions according to the mode signal from the charge connector lock switch, and the EVSE connection signal received from the PDM (Power Delivery Module) via CAN communication. If the conditions are met, VCM turns ON the charge connector lock actuator relay and operates the charge connector lock actuator in the close direction to lock the normal charge connector.

When the charge port lid opener switch signal from the charge port lid opener switch is received, or when the charge port lid open request signal for the charge port lid opener button is received from the BCM via CAN communication. If normal charging is stopped and other unlock conditions are met, the VCM turns ON the charge connector lock actuator relay and operates the charge connector lock actuator in the open direction to unlock the normal charge connector.

The lock modes are as per the following.

Lock mode	FUNCTION DESCRIPTION
LOCK mode	Automatically locks when the normal charge connector is connected.
AUTO mode	Locks only during normal charging. (Unlocks automatically when charging is completed.)
UNLOCK mode	Charging connector is not locked.

NOTE: For details of the functions in each mode and the actuator operations, refer to "CHARGE PORT CONTROL: SYSTEM DESCRIPTION ".
