Two divisions, one team. EV Parts rebuilds the high-voltage units that keep electric and hybrid vehicles running. EV Doctor finds the fault and fits them. Buy just the part, or let us do the whole job.
For workshops, fleets and owners who need the unit. We rebuild your failed part or supply a remanufactured exchange unit from stock.
For owners and fleets who want it fixed. Bring the vehicle in and our EV technicians diagnose it, fit the right part and hand it back road-tested.
Remanufacturing process, the same for every unit we rebuild
Of units bench-tested under load before they leave the workshop
Of high-voltage EV and hybrid parts, plus others on request
Recondition your unit, take a rebuilt exchange unit, or have EV Doctor supply and fit it
We remanufacture the high-voltage units that dealers usually only replace: traction batteries, e-motors, inverters, OBCs, e-compressors, PTC heaters and EPS racks. Each one is stripped to component level, rebuilt with new wear parts and validated on the bench before it goes back in a vehicle.
Every unit leaves with an end-of-line test report and a warranty, so the workshop fitting it knows exactly what it's getting.
| Test | Condition | Result |
|---|---|---|
| Insulation resistance | 1 000 V DC | >500 MΩ |
| Hipot | 2.5 kV · 60 s | Pass |
| Coolant leak | 2.0 bar · 10 min | No drop |
| Load run | Rated current · 20 min | Pass |
| CAN communication | Vehicle protocol | Pass |
Send us the failed unit. We diagnose it on the bench, quote you, then rebuild it with new wear parts and put it through a full end-of-line test before it goes back.
When the vehicle can't stand, fit a remanufactured unit from our stock and send your failed unit back to us as the core.
Bring the vehicle to EV Doctor. We diagnose the fault, supply the remanufactured part and fit it, so one team owns the job from start to finish.
EV Doctor is the hands-on side of EV Parts. Bring the vehicle in and our EV-trained technicians find the fault, swap the unit for a rebuilt one and hand it back tested, so you deal with one team from diagnosis to drive-away.
Most high-voltage failures come down to one component inside the unit: a DC-link capacitor, a bearing, a resolver, a weak cell module. Replace that, along with everything else that has aged, and the unit is good for another life. Pick a part to see the common failure modes and how we fix them.
A repair fixes the one thing that failed. Remanufacturing strips the unit to component level, replaces every wear and age-related part, and validates it on an end-of-line test bench. That's the difference between a comeback in six months and a unit you fit and forget.
Every unit goes through the same seven stages, whatever the part.
We log the unit against the vehicle, part number and the fault you reported, and record the core's condition before anything is opened.
The unit is tested before teardown, so we confirm the real fault instead of guessing. Fault codes from the vehicle are compared with what we see on the bench.
Complete disassembly. Housings, heat sinks and coolant passages are cleaned of old oil, coolant residue, corrosion and dirt.
Every part is measured and checked against spec. Anything worn, aged or out of tolerance is marked for replacement, not just the part that failed.
Seals, gaskets, bearings and known failure items are always replaced. Electronics are repaired at board level, and power stages are reassembled with fresh thermal interface material.
The finished unit is tested under realistic load, and has to pass before it can be signed off. Results are recorded against the unit.
Sealed, labelled and packed to protect connectors and coolant ports, and sent with its test record and warranty.
| Compare | Quick repair | EV Parts recon | New OEM part |
|---|---|---|---|
| What's done | The failed component only | Stripped to component level, all wear and aged parts replaced | Brand-new unit |
| Testing | Often just a quick function check | Bench diagnosis, then full end-of-line test with a written report | Factory tested |
| Cost | Lowest | A fraction of new | Highest |
| Availability | Varies | Rebuild your unit, or take an exchange unit | Often weeks on back-order |
| Warranty | Limited or none | Warranty on every unit | Manufacturer warranty |
OEM high-voltage parts are expensive and often on back-order for weeks. A remanufactured unit gets the vehicle back on the road sooner, at a fraction of the price.
You do the R&R, we rebuild the unit. It comes back tested to OEM spec with an end-of-line report, so you fit it once and don't see the car back as a comeback.
Cut vehicle-off-road (VOR) time. Fit an exchange unit from our stock, send back the core, and the vehicle is back earning.
A damaged inverter or battery pack can make a claim uneconomical to repair. A remanufactured unit costs far less than new OEM, which keeps more vehicles out of the total-loss column.
Out of warranty and quoted for a new OEM part? Get a recon price from us first, and let EV Doctor fit it. Same unit, rebuilt and bench-tested, for a fraction of the cost.
Takes about two minutes. Include the OEM part number, VIN and any fault codes (DTCs) and we can quote faster.
