JAECOO 7 PHEV: Charging does not start after connecting the portable AC charger
Symptoms
- Charging is unavailable after the portable AC charging equipment is connected. [1]
Possible causes
- The manual checks grounding, supply voltage and connection status; the control box indicators also distinguish communication, leakage current, overcurrent and other states. [1]
Checks
- Record the control box indications and identify the state using the source table; check grounding, power supply and the vehicle connection. Do not open the control box; electrical testing must be left to a qualified technician with the relevant expertise. [1]
What to do
- Rectify identified power supply or connection problems; if the equipment is abnormal or charging remains unavailable, have it checked at a service centre. Do not conclude that the onboard charger is damaged from the symptom alone. [1]
