Post-Installation Charger Recovery
Supercharge
EVGridCoop supports charging station owners, charging point operators, fleets, utilities, and commercial sites with field repair services for high-output DC fast chargers. Our technicians perform structured diagnostics across power conversion, communication, cooling, user interface, payment, safety, cabling, and connector systems.
Common Systems We Diagnose
• AC input power, disconnects, breakers, fuses, grounding, surge protection, and switchgear.
• Power modules, rectifiers, IGBT systems, DC bus, capacitors, contactors, insulation monitoring, and output relays.
• Cooling fans, liquid-cooled cable systems, filters, airflow restrictions, pumps, temperature sensors, and thermal derating conditions.
• CCS/NACS cables, connectors, latch systems, pilot communication, pins, handles, and cable retractors.
• OCPP network communication, modem/router status, firmware errors, payment terminal failures, display issues, and app status mismatches.
EVGridCoop should strongly highlight a laboratory repair center because it separates the cooperative from basic field service providers. Many failures are caused by sub-components that can be diagnosed, tested, repaired, or rebuilt rather than immediately replacing high-cost assemblies.
Laboratory Capabilities to Present
• Power module diagnostics and failure analysis.
• PCB and communication board troubleshooting.
• Capacitor, fan, relay, sensor, and connector testing.
• Cable and connector evaluation, including liquid-cooling issues where applicable.
• Bench testing, thermal testing, load simulation support, and documentation.
• Repair recommendations that compare cost, downtime, and OEM replacement options
