The wake-on-charge module manages the vehicle controller power mode for wake and sleep. It has a charger status indication when the vehicle is plugged in (on-charge). It features a CAN 2.0B port.

It performs the following functions.

• Module Wake/Sleep
• VCU Wake/Sleep
• Delayed Module Sleep/VCU Re-wake
• Control of power mode
• LED Control (separately)
• Status Feedback over CAN of all inputs and outputs

The primary function of the module is to wake the Vehicle Control Unit (VCU) and control status LEDs for the charger when the vehicle is plugged in to charge. The on-vehicle charger shares the Control Pilot signal input with the Wake-on-charge module. This input wakes up the Wake-on-charge module which in turn enables an output to wake the VCU. Control of the LED output drivers is in response to CAN messages from the VCU. When the VCU is ready to shut down the following can occur. The LEDs are controlled by the last received settings from the VCU command and the Wake-on-charge module will either sleep or re-wake the VCU after a controlled timer delay or if the 12 VDC battery input voltage goes below a controlled threshold. Removal of the Control Pilot input signal after the VCU goes to sleep also sends the Wake-on-charge module to sleep. The unit ships with factory defaults. The end user must configure the unit for their application.
