The equipment to be charged refers to equipment with a charging requirement. In the present embodiment, the device to be charged includes, but is not limited to, vehicles that require electric power as a power source, such as a pure electric vehicle, a hybrid electric vehicle, and an electric bicycle. The charging request refers to a request transmitted when the device to be charged needs to be charged. In this embodiment, the charging request may be sent by a user through a mobile terminal, for example, a device such as a mobile phone; or the charging pile may detect a request sent when the device to be charged is connected to the charging pile. Specifically, the charging request is used to instruct the charging control device to acquire charging demand information of the charging equipment. The charging demand information refers to demand information for charging of the device to be charged. In this embodiment, the charging demand information may be a rated charging parameter such as a rated charging voltage and a rated charging current of the device to be charged.

In this embodiment, the charging demand information is preferably a rated charging parameter. It can be understood that, under some conditions, a user may select a charging pile inconsistent with the rated charging parameter of the device to be charged for charging, and at this time, the rated charging parameter is used as the charging requirement information, so that the service life of the device to be charged can be prolonged.

In addition, because green electricity generation module has green energy attribute, when green electricity generation module can satisfy the demand of charging, can supply power to filling the electric pile through green electricity generation module, can reduce the loss of non renewable energy.
