Critical
The Alpitronic Hypercharger failed during the precharge phase. Before DC charging starts, the charger must match its output voltage to the vehicle's battery voltage. If this fails, charging cannot begin.
What to do
- Unplug, wait 30 seconds, and try again
- Make sure the connector is fully seated in the charge port
- If using CCS, try the other CCS connector on the unit if available
- This can be caused by a vehicle-side issue. Try a different charger brand to confirm
Who's responsible?
- This is likely a charger hardware issue
- This may be a vehicle issue
