NRGkick EV Home Chargers Error Codes

E01

Charging session does not start; app or LEDs indicate general fault E01 shortly after plugging into the vehicle.

General Internal Fault / Self-Test Failure

E02

Charging stops or will not start; display/app shows E02 indicating overtemperature or thermal protection.

Overtemperature Protection Triggered

E03

Charger refuses to start; app or LEDs indicate E03 related to ground/earth fault or missing protective earth.

Protective Earth (PE) Fault / Ground Monitoring Error

E04

Charging does not start; charger shows E04 indicating residual current device (RCD) or leakage current fault.

Residual Current / Leakage Fault Detection

E05

Charger displays E05 and refuses to charge, indicating overvoltage on the supply line.

Input Overvoltage Protection

E06

Charging stops or will not start; E06 indicates undervoltage or brownout condition on the supply.

Input Undervoltage / Brownout Detection

E07

Charger shows E07 and does not start charging; often associated with phase loss or phase imbalance on three-phase supply.

Phase Loss / Phase Imbalance Detection

E08

Charging fails to start; E08 indicates pilot signal or control pilot (CP) communication error with the vehicle.

Control Pilot Signal Fault

E09

Charger shows E09; charging stops abruptly or will not start, often related to proximity (PP) or plug detection fault.

Proximity Pilot / Plug Detection Fault

E10

Charger indicates E10; internal relay or contactor test fails and charging is blocked.

Main Contactor / Relay Stuck or Open

E11

Charger shows E11; internal self-test reports current measurement or calibration error.

Current Sensor / Measurement Fault

E12

Charger displays E12; internal communication error between control PCB and power module or communication bus fault.

Internal Communication Bus Failure

E13

Charger shows E13; often associated with Wi-Fi/Bluetooth module fault or communication error with connectivity module.

Wireless Communication Module Failure

E14

Charger indicates E14; internal memory or configuration error detected during startup.

Non-Volatile Memory / Configuration Corruption

E15

Charger shows E15; internal clock or metering synchronization error, often affecting energy logging and scheduled charging.

Real-Time Clock / Meter Synchronization Fault

E16

Charger displays E16; internal temperature sensor mismatch or sensor open/short detected.

Temperature Sensor Circuit Fault

E17

Charger shows E17; indicates internal power supply fault or low auxiliary voltage.

Auxiliary Power Supply Failure

E18

Charger indicates E18; often associated with load management or external control signal error (e.g., smart home or grid control input).

External Control / Load Management Interface Fault

E19

Charger shows E19; internal self-test detects insulation monitoring or isolation fault within the charger.

Internal Insulation / Isolation Fault

E20

Charger displays E20; indicates overcurrent or short-circuit event detected on output to vehicle.

Output Overcurrent / Short-Circuit Protection

Symptom

Charger body or cable makes unusual buzzing, humming, or clicking noises during operation.

Mechanical Vibration / Electrical Noise from Relays or Coils

Symptom

Charger cable insulation is cracked, cut, or heavily abraded, though the charger may still function.

Mechanical Cable Damage / Insulation Compromise

Symptom

Charger cannot be found or paired via Bluetooth, even at close range, though it charges normally.

Bluetooth Connectivity Failure

Symptom

Charger cannot connect to Wi-Fi network or frequently drops Wi-Fi connection, but Bluetooth works.

Wi-Fi Connectivity / RF Performance Issue

Symptom

Charger does not start at all (no LEDs, no display, no app connection) when plugged into a known-good outlet.

Complete Power Loss / No Power-Up

Symptom

Charger enclosure shows cracks, loose end caps, or compromised seals, especially after impact or drop.

Mechanical Enclosure Damage / IP Rating Compromise

Symptom

Charger gets very hot to the touch during normal charging, even at moderate current, but no error code is displayed.

Excessive Thermal Load / Poor Heat Dissipation

Symptom

Charger housing or plug emits a burning smell or shows discoloration after or during charging.

Overheating / Localized Thermal Damage

Symptom

Charger LEDs or display flicker or dim randomly while charging, but charging may continue.

Low-Voltage Supply Instability / Display Power Issue

Symptom

Charger powers up and connects to app, but vehicle does not charge and no error code is shown; vehicle may show 'charging station error'.

Handshake / Pilot Signal Level Mismatch

Symptom

Charger trips the household RCD or circuit breaker immediately when plugged in, even before connecting to a vehicle.

Input Short or Leakage to Earth

Symptom

Charger trips the RCD or breaker only after charging has been running for some time.

Thermal Leakage Increase / Load-Dependent Fault

Symptom

Charging stops intermittently; charger restarts or pauses frequently without clear error codes.

Intermittent Connection / Supply Instability

Symptom

Integrated cable strain relief at the charger body or plug is loose or damaged, allowing the cable to move excessively.

Strain Relief Failure

Symptom

Integrated energy meter readings are clearly inaccurate (e.g., much higher or lower than vehicle-reported energy).

Energy Meter Calibration Drift / Measurement Error

Symptom

Scheduled charging or time-based features do not start at the programmed time, though manual charging works.

Scheduling / Timekeeping Malfunction

Symptom

Type 2 vehicle connector does not latch securely into the vehicle inlet or is difficult to insert/remove.

Mechanical Wear or Deformation of Vehicle Plug

Symptom

Visible arcing or sparking when plugging the NRGkick into the mains outlet or when connecting to the vehicle.

Contact Wear / Poor Connection Causing Arcing
