/* TODO: /* TODO:
This integration is still ongoing. Here is what still needs to be done in order to use this battery type This integration is still ongoing. The same integration can be used on multiple variants of the Stellantis platforms
- Disable the isolation resistance requirement that opens contactors after 30s under load. Factory mode? - eCMP: Disable the isolation resistance requirement that opens contactors after 30s under load. Factory mode?
- MysteryVan: Map more values from constantly transmitted instead of PID
- ADD CAN sending towards the battery (CAN-logs of full vehicle wanted!)
- Following CAN messages need to be sent towards it:
- VCU: 4C9 , 565 , 398, 448, 458, 4F1 , 342, 3E2 , 402 , 422 , 482 4D1
- CMM: 478 , 558, 1A8, 4B8 1F8 498 4E8
- OBC: 531 441 541 551 3C1
- BSIInfo_382
- VCU_BSI_Wakeup_27A
- V2_BSI_552
- CRASH_4C8
- EVSE plug in (optional): 108, 109, 119
- CRASH_4C8
- CRNT_SENS_095
- MCU 526
- JDD 55F NEW
- STLA medium: Everything missing
- ADD CAN sending towards the battery (CAN-logs of full vehicle wanted!)
