Cheng Tu.As shown in Fig. 2 the present invention the same off-board DC charging motor of use in different charging modules charging method include with
Lower step：
First, the control method of each different charging module from same producer or different manufacturers is all imported into charging pile control
In the method base of device processed.
Wherein, the control method for it is being provided by charging module producer, for control charging module switching on and shutting down, work shape
State gathers and set the communications protocol and control flow of output voltage and electric current.The manufacturer of charging module is providing charging
While module, its corresponding control method can be provided.In the present invention, it is only necessary to which the control method for providing producer is imported
Into the method base of charging pile controller.
In the present invention, it is preferred to, the control method of the charging module of all models of current all producers is all imported
Into the method base of charging pile controller.So, no matter which type of charging module is used in charger, can be using this
The method of invention is charged.
Secondly, multiple different charging modules are connected with the charging pile controller by CAN.
In the present invention, the multiple different charging modules are multiple charging moulds in same off-board DC charging motor
Block, it is, the charging module 1, charging module 2, charging module 3 in Fig. 1 are until charging module N.These charging modules its can
To be same producer or different manufacturers.Certainly, according to the difference of charger, its model is probably different.
Again, when the charging pile controller starts first, coupled each institute is directed in methods described storehouse
The charging module 1 in charging module, that is, Fig. 1, charging module 2, charging module 3 are stated until charging module N looks for energy respectively
Enough control its control method.Because the control method of the charging module of various models is all imported into charging pile control first
Method is taken a fancy to, therefore, and for each charging module, can find can control its control method.
