ℹ️ The pack is separated in two packs, be sure to get both pieces!

Communication wiring

ℹ️ Note, the P-CAN and H-CAN networks need to be joined together. The Battery-Emulator needs to send messages towards both CAN buses for the battery to be able to close contactors.

Connect the following:

• P/H-CAN High -To LilyGo CAN-H
• P/H-CAN Low - To LilyGo CAN-L
• Pin 1 & 2 - To 12V supply
• Pin 3 & 14 - Short together by installing the Service Plug
• Pin 33 & 32 - To GND for 12V supply
• Pin 12 - To 12V Supply (this is the wakeup signal)

Compiling the software for this battery

In the USER_SETTINGS.h file, enable the line that contains #define SANTA_FE_PHEV_BATTERY. Enabling is done by removing the two // before the line. Then select the inverter protocol you want to use and upload to the board!
