Abstract

This invention provides a control device for an electromotor charge system including a connection plug, a supply and an output end of a control signal, in which, said connection plug includes two parts interplugged to each other, the output of the control signal is connected with the positive of the supply, the first part of the plug includes a magnet, the second part includes a magnetic induction switch to compose a loop with the supply when it is closed.

Description

Technical field [0001] The invention relates to a control device for an electric vehicle charging system. Background technique [0002] The electric vehicle charging system uses a high-voltage charger to charge the power battery pack of the electric vehicle. When charging, the charger and the power battery pack are connected through a connecting plug, and when the connecting plug is connected, a control signal is sent to start the charging system. The control signal in the existing electric vehicle charging system is provided by the following control device. The main part of this control device is the connecting plug. The connecting plug includes two parts: one part is a metal sensor installed near the end of the connecting plug. , The other part is the metal sheet installed on the charger end of the connecting plug, so that when the two parts of the connecting plug are plugged in, the metal sheet is close to the metal sensor, and the switch circuit in the metal sensor is turned ...
