Battery: Stellantis eCMP (Citroen, DS, Opel, Peugeot) - dalathegreat/Battery-Emulator GitHub Wiki
[!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.
Note on stationary storage :notebook: :zap:
To use the eCMP battery in stationary storage, the BMS needs to be isolated to keep contactors engaged. This requires opening the battery, exposing yourself to 400V. Only proceed with this battery if you are OK with High Voltage work. For the full procedure, see this section of the wiki
Supported Stellantis e-CMP batteries
The following eCMP ( Peugeot, Citroën, DS, Opel och Vauxhall ) batteries are currently supported
- Citroen ë-C4 (2020-)
- DS DS3 (2020-)
- Opel/Vauxhall Corsa-e/Mokka-e (2019-)
- Peugeot e-208/e-2008(2020-)
- Jumpy/Partner/Vivaro/Proace (2020-)
Supported 50kWh & 75kWh VAN? platform batteries
The same Stellantis eCMP platform integration can be used for some Toyota/Citroen/Fiat/Opel/Peugeot/Vauxhall van batteries. These batteries come in 50 and 75kWh sizes. It is still unclear what packs work, and which require more integration. It is also unclear what specific platform these batteries are.

Isolating the BMS
[!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.
The eCMP BMS performs real time insulation monitoring. When installing the battery to a stationary storage system, the solar inverter will start to perform insulation monitoring. This means the vehicle monitoring is no longer required, and unfortunately on the eCMP this monitoring will incorrectly detect leakage and open contactors after 1 minute when in use.
To get around this issue, we need to disable the insulation monitoring on the BMS. The only known way at this stage is to open up the battery, and insulate the BMS grounding points. This effectively disables the isolation monitoring from interfering with the contactors
To perform this, open up the battery and locate the BMS. Isolate the part circled in red.
Unlocking the battery
Under the "More Battery Info" page you can run collision unlock, contactor stuck unlock, and isolation error unlocking procedures. Remember to press the "Open contactors" button via the main page before running these requests, otherwise they wont work.
