Embodiment Construction

[0029] Figures 1a-4b are schematic diagrams of three embodiments of the present invention (external outlet type, tail outlet type, and upper hand-clasp type) respectively. In each embodiment, the charging interface system of the charging gun includes five structural units: a CAN line, a plug-and-plug interface, a wrench, an external (or tail) outlet system, and a plug-and-plug sensing system for the charging gun.

[0030] The CAN line structural unit includes a CAN line, a charging port CAN line interface (ie, a vehicle CAN line interface) 1 and a charging gun CAN line interface (ie, a gun-mounted CAN line interface) 15 . The function of the CAN line is for the communication between the charging cabinet and the whole vehicle. Through it, the state of the battery can be monitored at any time to avoid overcharging, overheating and other states, and ensure charging safety.

[0031] The plug-in interface structural unit includes a plug 4 , a plug core 12 , a socket body 2 , a sock...

Abstract

The invention discloses a charging socket and a charging gun of an electric automobile. The charging socket comprises a socket body and a socket core, wherein, the socket body is arranged on an automobile; the socket core is arranged in the socket body. The charging socket also comprises a localizer arranged on the socket body, and the localizer is used for carrying out the location of the charging gun. The invention also comprises a magnet at one side and a convertor, wherein, the magnet is arranged on the localizer and matched with the charging gun; the convertor is arranged at a place near the magnet. The convertor is used for transforming the change of a magnetic field into an electrical signal. A CAN line and a charging line on the charging gun are mutually arranged separately. The structure of the charging gun is matched with the charging gun. The invention has simple operation, safe operation, easy installation and easy maintenance.

Description

【Technical field】 [0001] The invention belongs to the field of battery pack charging, and relates to a charging device for an electric vehicle battery pack, in particular to a charging device for an electric vehicle. 【Background technique】 [0002] With the increase in oil consumption and the popularization of fuel vehicles, the energy crisis is slowly emerging, and the importance of new energy alternative technologies is becoming increasingly apparent. At present, the research on electric vehicles is becoming more and more mature. In the design of electric vehicles, power batteries are used to provide driving energy, which involves charging the power batteries. For example, in electric vehicle charging stations, high current and high voltage charging methods are usually used. So pay attention to high voltage protection. [0003] Electric vehicles need to be protected by CAN lines when charging, and the operation of the charging gun requires high voltage resistance, light...
