Temperature and Humidity Effect on the Indication Error for AC Charging Point

Aiming at the problem of whether the indication error of the AC charging point for electric vehicle is influenced by the ambient temperature and humidity, an experimental method was used to measure the indication error of the AC charging point using the special AC charging point tester with the temperature and humidity as the experimental variables. The relationship between the changes of ambient temperature and humidity and the changes of the indication error of the AC charging point was given. Then the reason of the effect of the ambient temperature and humidity on the indication error of the AC charging point was analyzed briefly. Finally, the conclusion that the change of indication error of the AC charging point was rated to the changes of the ambient temperature ,instead of the changes of the ambient humidity ware obtained.
