Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and examples.

Referring to fig. 1 and 2, an embodiment of a modular charging pile 10 of the present invention is suitable for charging an electric vehicle (not shown). This fill electric pile 10 contains a shell 1, a support 2, six modules of charging 3, an output module 4, a control module 5, a switching module 6 and a drive module 7.

The housing 1 is substantially rectangular, and can provide protection and waterproof functions for the charging module 3, the output module 4, the control module 5, the switching module 6 and the driving module 7 disposed in the housing 1. The housing 1 has a detachable front wall 11, a detachable rear wall 12 and two side walls 13 connecting the front wall 11 and the rear wall 12.

Referring to fig. 2 to 5, the bracket 2 is disposed in the housing 1 and has a plurality of accommodating grooves 21 arranged up and down, and the accommodating grooves 21 are used for the charging module 3, the control module 5, the switching module 6 and the driving module 7 to be disposed and positioned. The charging modules 3 are connected in parallel, each charging module 3 includes a charging housing 31 disposed in one of the accommodating grooves 21 of the bracket 2 and a charging unit 32 disposed in the charging housing 31, the charging housing 31 is detachably disposed in the accommodating groove 21 near the lower portion, and the charging unit 32 provides voltage and current required for charging. The number of the charging modules 3 may be configured and adjusted according to the output power preset in the charging pile 10, and is not limited to six in the embodiment, so long as at least one charging module is provided.

Referring to fig. 2, 3 and 5, the control module 5 includes a control housing 51 detachably disposed in one of the accommodating grooves 21 of the bracket 2 and a control unit 52 electrically connected to the charging unit 32 and the output module 4. The control unit 52 is a mechanism for managing and controlling all functions of the charging pile 10, and includes functions of monitoring the insulation at the start, interacting with the real-time charging status data of the vehicle-side BMS, communicating with the charging operation management background, controlling the start and stop of the charging, and the like, and is mainly used for controlling whether the output terminal 41 of the output module 4 can charge the electric vehicle.

The output module 4 is disposed on the housing 1 and electrically connected to the charging unit 32, and includes two output terminals 41, the output terminal 41 can be, for example, a charging gun, and is hung on the sidewall 13 of the housing 1, the output terminal 41 is electrically connected to the output of the switching module 6, and can be connected to the electric vehicle to charge the electric vehicle.
