Revision as of 21:49, 9 January 2023
In addition to the BMW 5 Series (G30) 530e the same battery pack can be found in the 7 Series (G12) 740e as well as the X Series (F15) X5. These battery packs consist of six battery modules yielding 351 volts. The same battery modules can be found in the 3 Series (F30) 330e but in a smaller form factor made up of only five modules and 293 volts.
First Gen (-2018)
The Electrical Energy Storage System in the 530e as well as the 740e has a code name of SP06 and a capacity of 26 Ah.
Second Gen (2019-present)
The newer SP41 high-voltage battery was installed in the G30 as well as the G12 Plug-in Hybrid Electric Vehicles starting in July of 2019. It has the same basic design as the SP06. The most significant change is the cell capacity increase from 26 Ah to 34 Ah.

Battery Management System, BMS
There is a SimpBMS version available on GitHub called BMWPhevBMS https://github.com/Tom-evnut/BMWPhevBMS created by Tome de Bree.
Wiring/pinouts
When using SimpBMS, the original BMW BMS master module should be unplugged (blue plug). This plug should instead be used to power the BMS slave modules and for the CAN connection to slave modules. See pinout below.
It's important to note that each plug in the wiring harness has an 'in' and an 'out' pin. I.e., the 5V, GND, and CAN connections are chained from one slave module to the next. So, if for some reason you have one of the slave modules unplugged, you may need to jumper the pins in that plug or else the modules further down the chain may not work.
