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.
