Upgrade kit to replace the electronics (EVSE, ESP32) of a WARP3 Charger with the electronics of a WARP4 Charger. After the upgrade, many features of the WARP4 Charger are available, in particular ISO 15118 communication with the vehicle (e.g. for SoC display and Autocharge).

The kit contains a preassembled electronics stack consisting of:

• WARP ESP32 Ethernet Brick 2.3
• EVSE Bricklet 4.4
• WARP PLC 1.1
• WARP4 PCB mechanical set

Also included are two WARP4 stickers with the new WLAN access data.

Swapping the electronics is easy: The electronics of WARP3 and WARP4 are mechanically compatible and all connections have remained identical, so the complete stack can simply be exchanged on the DIN rail and all existing cables can be reused. A detailed step-by-step guide with photos can be found in our documentation: Upgrade from WARP3 to WARP4.
