High-Voltage Battery Repair & Rebuild Solutions
EV batteries are high-cost, structural vehicle components. A minor underbody impact or a single faulty module often forces a full pack replacement, a cost that runs into five figures. YES-EU avoids that cost with targeted, component-level battery repair. By isolating and repairing the actual fault, we save 50-70% compared to a full pack replacement. Repairing saves you the purchase of a new battery pack, cutting claim costs for insurance companies and keeping maintenance predictable for fleet operators.
Component-Level Intervention vs. Full Pack Replacement
- Five figures Cost of a full pack replacement
- 50-70% Savings through targeted repair

Warranty-aligned repair, original parts.
Operating as an official European aftermarket NING Service partner, YES-EU carries out strictly warranty-aligned repairs. Our European network is staffed by certified high-voltage specialists who use direct OEM diagnostic support and original spare parts and modules. Every repair takes place in battery service workshops in compliance with European regulations, equipped for both minor defect corrections and major high-voltage system overhauls. Where the situation allows, our mobile technicians can also carry out repairs at the client's premises.

What does "insurance-grade repair" mean?
An insurance-grade repair is one carried out to a standard that an insurer can accept and sign off. In practice this means the work uses original OEM parts and certified high-voltage specialists, the battery is tested after repair to confirm it is safe and performing correctly, and every step is documented in an audit-ready report the insurer can rely on for the claim.
Diagnostics & Checks
We run full Battery Management System (BMS) diagnostics, isolation testing, and thermal analysis to trace faults and measure remaining pack capacity.
Performance Validation & SoH Testing
Post-repair, batteries undergo strict performance validation and State-of-Health (SoH) testing.
Insurer-Ready Compliance Reports
We generate insurer-ready compliance reports, provide State-of-Health (SoH) certification for remarketing, and prepare assets for EU Battery Passport regulatory alignment.
Residual Value Extension
We generate official, audit-ready SoH reports that help extend and protect residual value, ensuring full compliance with EU Battery Passport mandates.
EU Battery Passport Alignment
Central to new European legislation is the EU Battery Passport, which requires transparent digital tracking of a battery's operational history, material composition, and State-of-Health (SoH).
For aging fleets, we rebuild battery packs to extend their working life.
