JAECOO 7 PHEV: Power supply trips immediately when portable AC charging is energised

Symptoms

  • The power supply trips when portable AC charging equipment is used. [1]

Possible causes

  • The source manual calls for checks of grounding, equipment short circuits and the combined load of all electrical equipment; it does not establish onboard charger damage from this. [1]

Checks

  • Stop repeatedly energising the equipment; have a qualified technician check grounding, equipment short circuits and the total load. Compare the control box light states; dismantling or repairing the control box is prohibited. [1]

What to do

  • Address the identified power supply or equipment problem; refer persistent faults to a service centre. Do not bypass grounding/leakage-current protection. [1]

Applicability and limits

  • Only applies to the JAECOO 7 PHEV configuration in the source; model year unconfirmed. Covers the portable AC equipment supplied with the vehicle; do not generalise to all public charging stations; the vehicle model database is empty and no model is linked. Do not extend to other models. Scope: unknown [1]
