Charging control method, charging control system

Abstract

The invention relates to a charging control method, which is used to control the charging of an electric vehicle after upgrading firmware or software. The method includes: receiving an upgrade completion signal sent by the electric vehicle; determining the identification information of the charging pile connected to the electric vehicle; instructing charging The pile outputs a PWM signal to the EV to start the charging process. The method automatically realizes the continuation of the charging process after the firmware or software upgrade is completed, which not only improves the overall working efficiency of the charging station, but also brings good user experience to the charging user.

Description

Charging control method and charging control system technical field The present invention relates to the technical field of electric vehicles, more particularly, to a kind of control electric vehicle in firmware or software How to charge after upgrade. Background technique In the AC charging process of the electric vehicle, if the firmware (or software) needs to be upgraded, the general way is For the sake of safety, stop charging first, that is, stop charging by opening the switch S2 inside the vehicle. However, the firmware (software The time required for the upgrade is much longer than the time the charging pile waits for the car to be recharged again, which makes the charging pile mistakenly believe that the car is fully charged. The electricity is completed, thereby stopping the output of the PWM signal. After the firmware upgrade is completed, if the car needs to continue to be charged, the charging pile will need at least one trigger signal, so that the cha...

AI Technical Summary

Problems solved by technology

However, the firmware (software) upgrade takes far longer than the charging pile waits for the car to charge again, so that the charging pile will mistakenly think that the car is fully charged and stop outputting the PWM signal.

[0003] After the firmware upgrade is completed, if the car needs to continue charging, the charging pile will need at least one trigger signal to make the charging pile continue charging after the car firmware upgrade is completed, otherwise the charging pile will not output PWM signals, which will cause the car to continue to charge. Failure

In addition, there are relatively complex interface circuits and control signal flows between the electric vehicle and the charging pile, and a single trigger signal may affect other circuits when the vehicle can continue to charge

[0004] On the other hand, the continuous charging of electric vehicles through manual means will take up extra labor, which will reduce the overall work efficiency of the charging station.
