Battery: Stellantis CMP Smart Car platform - 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.
Supported CMP Smart Car batteries
The Smart Car platform comes with:
- 29kWh LFP battery
- 44kWh LFP battery, 140Ah, 100S, 150x115x30cm dimensions, 350kg
[!CAUTION] If the battery is crashed hard, or detects a massive isolation leak, it will lock itself and display Battery Fault Level 5. Currently we have no way to reset this!

Connectors
From left to right, liquid cooling ports, HV connector, LV connector
HV connector
The main HV connector is an APTIV 35561611 RCS1200 SW F0T7-144-23 connector
There is also another HV connector on the back used for the DC fast charging port. It has a separate HVIL loop.
Low voltage connector
LFP low voltage connector - in stock on Mouser, in case you are not able to get the harness with the connector when you buy the battery. The connector has the pin numbering stamped on it.

Note on WUP
WakeUpPin (WUP) can be used to make the battery survive a reset/reboot in the software. If you connect all 4x 12V pins to the WUP pin via a relay/SSR, you can perform graceful reboots without needing to cycle 12V to the battery to get it to work after a reboot/OTA.
Software configuration
To use this battery, select the "Stellantis CMP Smart Car Battery" battery option
Troubleshooting
