EV won’t charge
Work outward: the granny lead and socket, the cable, the home unit or public charger, then the car. Most "EV won’t charge" cases are the charger or cable, not the battery.
What you might be seeing
- Charging fails to start, or stops early
- Works on public chargers but not at home (or vice versa)
- Error light on the wallbox or dashboard charge fault
The likely causes, honestly ranked
- Tripped RCBO/breaker on the home circuit
- Faulty or dirty cable/connector pins
- Wallbox fault or configuration (schedules, load management)
- Car-side: charge port lock, 12V battery health, software
Do this now
- Try a different charger (a public unit is a good cross-check) and a different cable if you have one
- Check the fuse board and the wallbox indicator legend
- Check the small 12V battery — a weak 12V causes strange EV faults including refusing to charge
- If the car faults on every charger and cable, book an EV-experienced garage
What to avoid
- Extension leads and adapters not rated for EV charging
- Repeated forced retries against a charger showing a fault

Frequently asked questions
Why does my EV charge in public but not at home?
That isolates the home circuit or wallbox: tripped protection, a schedule set in an app, or a unit fault. An electrician or your installer checks the unit; the car is likely fine.
Can a regular garage work on my EV?
Routine items yes; high-voltage work needs EV-trained technicians. Escargo lists garages declaring EV work — say your model when requesting.
Does the 12V battery really stop an EV?
Completely — the 12V system boots the car. A flat 12V leaves a healthy main battery locked out; it can be jumped or replaced like any 12V battery.
