We diagnose and repair EV batteries, hybrid systems and high-voltage components.
Electric and hybrid vehicles need more than a basic fault-code scan. We use specialist diagnostic methods, safe high-voltage procedures and real repair knowledge to find the cause of battery, charging and electrical faults.
Specialist EV Repair Process
From warning lights to no-charge faults, we investigate the system properly before recommending a repair.
EV and hybrid faults need specialist knowledge, not guesswork.
We work through the battery, charging, control and high-voltage systems to locate the real fault and recommend the right repair route.
EV & hybrid battery faults
Diagnosis of battery warning lights, weak modules, isolation faults, imbalance issues, range loss and battery communication faults.
Charging problems
Investigation of vehicles that will not charge, charge slowly, stop charging, fail to communicate with chargers or show charging errors.
High-voltage components
Checks for inverters, DC-DC converters, onboard chargers, high-voltage junction boxes, contactors, relays and control modules.
Warning lights & reduced power
Fault finding for EV system warnings, hybrid system warnings, turtle mode, drivetrain errors, reduced power and no-ready conditions.
Cooling and thermal faults
Battery and power electronics cooling checks, including pump faults, temperature sensor issues and overheating-related warning messages.
Electrical fault finding
Structured diagnosis of wiring faults, communication faults, module errors, sensor issues and system failures affecting EV and hybrid operation.
How we repair EV batteries and high-voltage systems
We do not simply clear fault codes and hope the problem disappears. We follow a controlled process to understand the fault, confirm the cause and protect the vehicle from unnecessary parts replacement.
1. Specialist diagnostic scan
We scan the battery management system, hybrid/EV control modules, charger, inverter, DC-DC converter and related systems to collect fault codes and live data.
2. Live data and system testing
We review voltage readings, temperature data, module behaviour, charging communication, contactor activity and system status to understand what is really happening.
3. Safe high-voltage inspection
Where required, we follow high-voltage safety procedures before inspecting cables, connectors, battery components, power electronics and insulation-related concerns.
4. Repair, retest and report
Once the fault route is confirmed, we advise the repair options, complete suitable work and retest the system so the customer understands what was found and repaired.
Book a repair inspection if your vehicle has any of these problems.
| Symptom | Possible Area | What We Check |
|---|---|---|
| EV or hybrid battery warning light | Battery / BMS | Fault codes, module data, SOC/SOH, voltage balance and system communication |
| Vehicle will not charge | Charging system | Charge port, onboard charger, control modules, cables, charger communication and safety locks |
| Reduced power or turtle mode | High-voltage drivetrain | Battery output, inverter data, temperature readings, isolation faults and control-module status |
| Hybrid system fault | Hybrid battery / inverter | Battery condition, inverter operation, DC-DC converter, cooling system and related wiring |
| Range has dropped | Battery health | Battery health, usable capacity, charging behaviour, cell/module imbalance and diagnostic history |
We understand EV systems from the battery pack to the wheels.
EV and hybrid faults can be expensive when diagnosed incorrectly. Our aim is to identify the fault properly, explain it clearly and recommend a practical repair path.
Safety-led work
High-voltage systems are treated carefully with a controlled diagnostic and repair approach.
Data-led diagnosis
We use diagnostic data, live readings and system tests instead of relying on guesswork.
Clear explanation
You receive a clear explanation of the fault, likely cause and recommended repair route.
Repair focused
Our goal is to repair intelligently and avoid unnecessary replacement where possible.
Choose the right level of EV or hybrid repair support.
Start with the level that matches your fault. If deeper work is needed, we will explain the next step clearly.
