EV Charging Repair & Service

Won't charge / no power

EV not charging at all? We trace the fault from the wall socket to the cell — supply, cable, port, on-board charger and BMS charge-enable.

AC · DC · OBC

Slow charging diagnosis

Charging far slower than rated? We measure real kW throughput and isolate the bottleneck — charger, cable, port contact, BMS throttle or thermal limit.

kW throughput test

On-board charger (OBC) repair

Internal AC→DC charger module failures — no output, mid-charge tripping, burnt smell, water ingress. Board-level repair or replacement.

OBC · rectifier

Charging port / inlet repair

Loose, melted, corroded or cracked charging inlet — pin resistance test, contact clean, or full port replacement to OEM spec.

Type 2 · CCS2 · GB/T

Home charger & wallbox

AC home charger install, no-output faults, RCBO / earth-leakage trips, and app / Wi-Fi pairing for 3.3 kW and 7.4 kW units.

DC fast charger service

Public, fleet and society DC charger faults — OCPP backend errors, connector damage, power-module and contactor repair.

CCS2 · OCPP · B2B

Charging cable & gun

Damaged Type-2 cables, portable travel chargers, control-pilot (CP/PP) faults, and burnt or arcing connector pins.

Charging error codes

Blinking LEDs, dashboard charge faults, charge-interrupt and handshake errors — decoded over CAN / the charger UI and fixed.

Earth leakage & safety

Ground-fault and leakage trips, insulation resistance test, and wiring / earthing checks so you can charge safely at home.
