Services

Our three service lines

From the first diagnosis to a unit that is ready to go back on the road — all under one roof.

Battery pack repair & remanufacturing

A full diagnosis first, then repair at component level — not just a unit swap.

  • Full pack diagnosis: insulation and air-tightness tests, internal resistance, capacity, and SOH determination
  • Module- and cell-level replacement and balancing, including BMS and sampling-harness repair
  • Repair of heater circuits and the thermal management loop
  • Handling of packs damaged by flooding, impact, overcharge, or over-discharge
  • Battery health report (SOH, internal resistance, cell-to-cell consistency)

Control system & traction motor repair

Fault tracing down to component level on high-voltage circuits.

  • Diagnosis and repair of MCU, VCU, OBC, and DCDC
  • Traction motors: bearings, resolvers, insulation, and cooling circuits
  • CAN bus diagnostics, fault-code reading, and data-stream analysis
  • High-voltage distribution, relays, fuses, and HV interlock circuits

Diagnosis, evaluation & technical reports

Data you can make decisions with, not just a verbal conclusion.

  • Two-way testing — on arrival and before hand-over — with traceable records
  • Dedicated 3E evaluation of accident vehicles, including technical opinions for insurance claims
  • Battery health assessment before a used-car transaction
  • Post-repair retesting to confirm the unit is genuinely ready

FAQ

Frequently asked questions

If your question is not here, just ask us on WhatsApp.

Which makes and models can you handle?

We handle battery packs, traction motors, and control units from a wide range of passenger and commercial EV brands. Send a photo of the unit label and the fault code on WhatsApp for an initial confirmation.

Can you repair at module and cell level?

Yes. We replace and balance at both module and cell level, including BMS, sampling-harness, and thermal-loop repair — without replacing the whole pack.

Do you take battery packs from accidents or flooding?

Yes, with a full evaluation first. After testing we give a clear recommendation — repair, remanufacture, or not economically repairable — together with the reasoning.

Can your report be used for an insurance claim?

Our reports cover SOH, internal resistance, cell-to-cell consistency, and a technical opinion for accident vehicles. They are used for used-car pricing and claim processes.

Do you sell the equipment without the repair service?

Of course. The battery diagnostics host PC, CAN cards, balancing equipment, and specialised tooling can all be bought separately, with usage training and technical support.

Do you serve workshops and dealers outside your city?

Yes. We ship equipment across Indonesia, and battery packs can be sent to our workshop. Contact us about a partner-workshop arrangement.
