⚡ Charger Shows an Error but Your EV Shows No Faults? Mobile EV Charging‑Fault Specialist in London
Vehicle‑Side Diagnostics • Charging Communication Repairs • On‑Site Support Across Greater London
If a public charger or home charger displays an error, but your EV shows no dashboard warnings, the issue is almost always a vehicle‑side communication or handshake fault. These problems can prevent charging even when the car appears healthy.
