Charging BMW models at home

[-Cappo-]

Friend of mine has some fairly new-build rentals (completed 3-4 years ago) and he had car chargers installed when the houses were built. A new tenant in one has reported that he can’t charge his BMW (don’t know model, sorry) and that he called BMW techs out to investigate.

BMW Techs said:

Need to check:

Earth Loop Impedance (Ze) & Earthing Quality (apparently BMWs are more sensitive to this than any other car brand) and a Firmware update.

The charger (Rolec) has been tested against a PHEV Range Rover and charges that no problem.

A small further fly is that the previous tenant also had an electric BMW of some sort, and my mate checked back with him and he said it wouldn’t charge his car either, but he didn’t flag that during his tenancy.

There are no known issues with the rest of the electrics at the house, there’s a current certificate signing everything off (for the tenancies).

Anybody know anything about this? Is it only BMWs? And what would the remedial work need/cost? Does it “just” need an extra earth rod sunk for the charger?

"A small further fly is that the previous tenant also had an electric BMW of some sort, and my mate checked back with him and he said it wouldn t charge his car either, but he didn t flag that during his tenancy."

Surely the tenancy would obliged him to flag that?
