Getting a BMS_A174 error.

Home Charger was working good for the first week (installed Nov. 29th) but now seems to be cutting off in the middle of charges.

On a 24 Amp installation from the electrician with it inside our garage, while parking the car outside of the garage.


Seems to charge for 2-3 hours, then cuts and I have to disconnect then reconnect the car port plug. Charging starts up again but can sometimes fail again. Gets me up to a 45% to 55% charge only.

As it happens from night charging, (typically kicking off between midnight and 2am) I don't notice until work the next day, typically 6am when it starts to warm up.

Any insight is appreciated, the apps and manuals didn't seem to explain anything.
