Battery: Jaguar I‐PACE
Caution
Working with high voltage is dangerous. Always follow local laws and regulations regarding high voltage work. If you are unsure about the rules in your country, consult a licensed electrician for more information.
This battery is currently being reverse engineered by @obbardc and Cory Mac - ØY Electrical (along with lots of help from @dalathegreat and other community members).
The battery has the internal contactor coils forceably controlled by the Battery-Emulator, using the CONTACTOR_CONTROL setting. This is because the
We need to verify if the cells are being properly balanced by the iPace BMS with the contactors forcibly engaged.
We made two videos about the reverse engineering:

- Part 2: Hacking a Scrapped £90,000 EV Battery to get FREE Electricity - DIY Vehicle to Grid - Part 2

- Engage battery contactors by sending the right CAN messages. See Issue: Jaguar iPace Battery Contactors do not yet close for more information.
- Confirm that cells are balanced during operation.
- Poll for all cellvoltages. There does not seem to be a UDS register/CANBUS register for this.
- Different keepalive/other CAN messages for >2021 models.
- LG's pouch cells in I-PACE have a habit of tabs becoming disconnected. This leads to modules becoming 3P rather than 4P. The I-PACE BMS wasn't flagging this in earlier firmware revisions leading to the module becoming overcharged and fires. Determine which models are used.
- BECM CAN ID is 0x7e4, returns data on 0x7ec.
- Appears to be in UDS format.
- Spreadsheet containing UDS PIDs and UDS Error codes
- For now see connector pinout spreadsheet
- 3x HV connectors with interlocks. TODO: Add diagram.
