We recommend that a car owner follows these steps when feeling that EV Charging Power is insufficient.
Step One: Confirm the power allowed by the grid and the rated power of the AC charging pile.
In general, the power allowed by the grid is usually at least 7 kW. Changan AC chargers offer 7 kW and 3.5 kW power options for vehicles.
Step Two: Check the situation on the vehicle side, including the power of the onboard charger (OBC) and charging settings.
The rated power of the OBC is generally 6.6 kW or 3.3 kW (mostly for hybrid models and small electric vehicles). Regarding charging settings on the vehicle’s system, it usually involves charging current limitations. For example, selecting 8A corresponds to a charging power of about 1.7 kW, 10A corresponds to about 2.2 kW, 16A corresponds to about 3.3 kW, and 32A corresponds to about 6.6 kW.
Step Three: Preliminary assessment of the actual charging power.
Expect charging at around 6.6 kW if the power confirmed in Step One is 7 kW and in Step Two it’s 6.6 kW. If one is 3.5 kW or 3.3 kW, anticipate a maximum of 3.3 kW.
Observe over time to determine consistency if the actual charging power doesn’t match.
For example, when the battery is almost fully charged, the charging power may decrease. High or low temperatures can also reduce power, and there are various other factors that may lower power.
Step Four: Problem resolution.(EV Charging Power)
If the expected charging power isn’t reached for a while, the car owner should drive to a public charging station for testing. If the issue is fixed there, the home charging pile or its installation may be the problem. Contact the service provider.If the problem continues at the public charging station, have the vehicle inspected at the 4S dealership.
Up to now, we have clarified the origin and resolution of the insufficient EV charging power issue.
This matter inherently possesses a degree of complexity and technicality. I have endeavored to explain it in layman’s terms as much as possible, and hopefully, it is understandable upon careful reading. If there are still difficulties in understanding or resolving the issue, please feel free to contact our team at any time.
