High-Voltage (HV) Battery Repair & Rebuild Solutions
EV batteries are high-cost, structural vehicle components. Minor underbody impacts or localized module faults frequently force full pack replacements, with costs ranging from €10,000 to over €35,000. YES-EU eliminates this inefficiency through targeted, component-level battery repair. By isolating faults and repairing specific damage, we achieve 50–70% cost savings compared to full pack replacements. This methodology significantly reduces claim severity for insurance companies and predictable maintenance costs for fleet operators.
Component-Level Intervention vs. Full Pack Replacement
- €10k–35k+ Cost of a full pack replacement
- 50–70% Savings through targeted repair
- L1 & L2 CATL-certified HV technicians
Warranty-aligned repair, original parts.
Operating as an official European aftermarket service partner for CATL and in strategic cooperation with Geely Group's VREMT brand, YES-EU executes strictly warranty-aligned repairs. Our European network is staffed by CATL-certified high-voltage technicians who utilize direct OEM diagnostic support and original spare parts and modules. Our facilities are engineered to handle both minor defect corrections and major high-voltage system overhauls.
Major overhauls and minor corrections.
-
Module Replacement
Targeted extraction and replacement of degraded or damaged battery modules using original OEM components.
-
Enclosure & Harness Servicing
Precision enclosure resealing and high-voltage harness repair, resolving issues caused by underbody impacts.
-
System Component Replacement
Replacement of high-voltage contactors and repair of HV interlock systems.

YES-EU manages the entire chain from incident intake to return-to-service.
Diagnostics & Triage
We execute comprehensive Battery Management System (BMS) diagnostics, isolation testing, and thermal analysis to trace faults and assess 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 residual value certification for remarketing, and prepare assets for EU Battery Passport regulatory alignment.
Residual Value Certification
We generate official, audit-ready SoH reports and residual value certifications, ensuring full compliance with EU Battery Passport mandates.
EU Battery Passport Alignment
Central to emerging European legislation is the EU Battery Passport, mandating transparent digital tracking of a battery's operational history, material composition, and State-of-Health (SoH).
For aging fleet assets, we offer comprehensive rebuild services engineered for lifecycle extension.
