Electric Vehicle (EV) Services

High-voltage specialists. Battery packs, isolation faults, charging systems, in the field.

Overview

Electric fleets can't wait weeks for a dealer slot. Our high-voltage specialists diagnose and repair battery-electric buses and trucks where they sit: safely, to OEM procedure, with the right PPE and tooling.

Why Mobile Matters

Most dealers have limited EV bays and long backlogs. A mobile high-voltage team restores your electric units to service without towing a bricked bus across the state. Battery and charging downtime is the new availability killer for electric fleets, and it's exactly what this team clears where the vehicle sits.

  • EV Battery Pack ReplacementHigh-voltage pack R&R performed to OEM procedure by qualified technicians: isolation, discharge, swap, commissioning. Done at your facility, no flatbed to the dealer.
  • High-Voltage DiagnosticsOEM-level HV diagnostics with insulation testing and live-data analysis on buses and trucks. We find the fault, not just the code.
  • High-Voltage Safety InspectionsDocumented HV safety inspections covering isolation integrity, interlocks, cabling and lockout compliance. Audit-ready records for your safety file.
  • EV Compressor ReplacementElectric compressor replacement with proper refrigerant handling and HV recommissioning, done on-site.
  • Charging System DiagnosticsCharge faults isolated across vehicle, cable and station. You find out whether it's the bus or the charger before you call the infrastructure vendor.
  • DC Fast Charger TroubleshootingOn-site DC fast charger fault isolation: communication, contactor and power-stage checks run to the charger manufacturer's own procedures.
  • Battery Cooling System RepairsThermal-management repairs: pumps, valves, coolant loops, with bleed and verification procedures that keep pack temperatures in spec.
  • High-Voltage Cable RepairsHV cable and connector repair or replacement under orange-cable handling protocol, with post-repair isolation testing before energizing.
