Charging System Service

EV Charging System Diagnosis & Repair

Charging problems stop your EV cold. From onboard charger faults to charge port issues and Level 2 charging problems — we diagnose and fix them all.

When Your EV Won't Charge

Charging system failures range from a simple charge port latch fault to a failed onboard charger or BMS communication error. Whatever the cause, we have the diagnostic tools and training to identify the specific fault and advise you on the repair options.

Common Charging Issues We Diagnose:

  • EV won't accept charge from Level 1 or Level 2
  • Charging stops before reaching target SOC
  • Reduced charging speed (slower than expected)
  • Charge port won't open or latch properly
  • Charging fault warning lights
  • DC fast charging (CCS / CHAdeMO) issues
  • Onboard charger (OBC) fault codes
  • Battery management system communication faults
  • PHEV charge system errors

Onboard Charger (OBC)

The onboard AC charger converts your home or public Level 2 supply to DC for the battery. OBC failures show as slow or no charging. We diagnose fault codes and test OBC performance.

Charge Port & Latch

Charge port actuators, latch mechanisms, and proximity pilot circuits are common failure points — especially in cold climates. We diagnose and repair port assembly faults.

BMS Communication

The Battery Management System controls when and how fast charging occurs. BMS faults can prevent charging entirely or cause premature cutoff. We read all BMS modules and fault histories.

DC Fast Charge Issues

Problems with CCS, CHAdeMO, or Tesla Supercharger compatibility can have multiple causes. We diagnose the vehicle side of DC fast-charge issues — inlet ports, control modules, and communication faults.

Charging Standards We Support

We service vehicles with all major North American charging standards.

J1772 / Level 2 AC

The standard Level 2 connector used by all non-Tesla EVs in North America. Powers all home EVSE and most public AC charging stations.

CCS1 (DC Fast)

Combined Charging System — the dominant DC fast-charge standard in North America, used by most non-Tesla EVs built after 2013.

CHAdeMO

DC fast-charge standard used by Nissan Leaf and some Mitsubishi models. Less common now but still active in older EV fleets.

NACS (Tesla)

Tesla's Native AC/DC port — also now being adopted by GM, Ford, and other OEMs. We service all NACS-equipped vehicles including adapter compatibility.
