High-voltage battery repair & rebuild.
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, achieving 50–70% cost savings compared to full pack replacement while reducing claim severity for insurers and 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 use 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.
-
Thermal Management

From incident intake to return-to-service.
Diagnostics & Triage
Comprehensive Battery Management System (BMS) diagnostics, isolation testing, and thermal analysis to trace faults and assess pack capacity before any intervention.
Performance Validation & SoH Testing
Post-repair, batteries undergo strict performance validation and State-of-Health (SoH) testing to confirm restored capacity and safe return-to-service.
Insurer-Ready Compliance Reports
We generate insurer-ready compliance reports with full repair histories, supporting audit and claims processes.
Residual Value Certification
Residual value certification prepares repaired and reconditioned assets for remarketing.
EU Battery Passport Alignment
Assets are prepared for EU Battery Passport regulatory alignment, supporting transparent digital tracking of operational history, material composition and SoH.
Engineered for lifecycle extension.
