EV traction battery pack repair and state-of-health testing in Zambia
Module-level diagnosis, rebalancing and repair of electric vehicle traction packs — instead of a replacement pack imported in dollars over 4–12 weeks.
What we do
Capacity and state-of-health (SoH) testing, cell and module voltage and temperature analysis, balancing, module replacement, bus-bar and interconnect repair, enclosure sealing and thermal-path inspection. Packs are tested under load, not just at rest.
Why a pack usually does not need replacing
A traction pack is modules and cells managed by a BMS. One weak module, a loose bus-bar, a failed temperature sensor or a BMS fault disables the whole pack while the remaining cells are healthy. Diagnosis at module level finds the fault; replacement throws away the other 95%.
Second-life storage
Packs no longer fit for traction often retain substantial capacity. We re-group matched modules behind a correctly configured BMS and build stationary storage for backup or solar — directly useful in a load-shedding market.
Terms
Written report per pack, 6-month workmanship warranty, standard 5–7 business day turnaround with 48–72 hour priority under a maintenance agreement, and a flat assessment fee with no repair fee if a pack proves beyond economical repair.
Questions we are asked
Can an EV battery be repaired in Zambia?
Yes, in most cases. We diagnose at cell and module level and repair the fault rather than importing a complete replacement pack.
How do you test battery state of health?
Capacity testing under load plus cell-level voltage and temperature analysis, reported as usable capacity against original capacity.
Can you fix lost range?
Often. Cell drift limits the pack to its weakest cell; balancing and replacing a genuinely failed module can restore a significant part of lost usable capacity.
Do you test packs before a used EV purchase?
Yes — state of health, BMS fault history and a written report before the money moves.
