Revision as of 09:27, 16 June 2021

The BMW LIM module is a CCS, CHAdeMO and AC charging controller. It is used to communicate between the vehicle and the public charging infrastructure, to allow fast charging to occur.

As these can be found affordably on eBay and from auto wreckers, they have been pursued as an open-source charger project.

LIM versions

Only AC_DCO versions work for CCS. (Check if you have a MAC adres on the sticker!)

The following SN are confirmed to work.

The LIM's are available new from BMW spare parts suppliers for € 240 but there is probably some programming necessary. ???

Power Limits

The limits for pre 2017/26 (Week 26 of 2017) are 0V-500V 0A-250A, post 2017/27 (Week 27 of 2017) 0V-1000V -500A-+500A.

Observations

VIN Numbers is not required for AC or DC fast charging to function

Functional LEMs have come from vehicles where the Air Bags have deployed, indicating that the module still works after a "Safety" event has occured
