Problems solved by technology

However, the fuse does not use any arc extinguishing measures. When the fuse is blown, an arc will be generated, and the arc may break down the battery, causing risks such as burning and explosion, which will cause the personal safety of passengers.
And the fuse is not supported by the shell, and the weakest part may break, thus reducing the safety and reliability of the battery module

Abstract

The invention discloses a battery connector, a battery module and an electric vehicle. The battery connector comprises a connecting sheet and a protecting assembly, wherein the connecting sheet is provided with a fuse part; the cross sectional area of the fuse part is smaller than that of the rest part; and the protecting assembly coats the outside of the fuse part. According to the battery connector of the electric vehicle disclosed by the embodiment of the invention, the fuse part of which the cross sectional area is smaller than that of the rest part is arranged on the connecting sheet; and the protecting assembly coats the outside of the fuse part, so that connection between batteries can be achieved; when a control circuit is abnormal, the connection between the batteries is timely cut off; the battery connector can play a protecting role in the batteries; an electric arc generated by fusing can be quickly extinguished; the risks of combustion, explosion and the like due to the fact that the electric arc breaks through the batteries are prevented; a potential safety hazard to a passenger can be avoided; and meanwhile, the protecting assembly can also support the housing ofthe fuse part to strengthen the connection reliability of the fuse part, so that the reliability of the connecting sheet is increased.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a battery connector, a battery module and an electric vehicle. Background technique [0002] Electric vehicles use battery modules as a power source for powered operation. In related technologies, a fuse device is used between the battery modules of an electric vehicle to prevent the connection between the battery modules from being disconnected in time when the control circuit fails, thereby cutting off the power supply and preventing accidents. However, the fuse does not use any arc-extinguishing measures. When the fuse is blown, an arc will be generated. The arc may penetrate the battery, causing risks such as combustion and explosion, thereby causing personal safety of passengers. Moreover, the fuse is not supported by a shell, and the weakest point may break, thereby reducing the safety and reliability of the battery module. Contents of the invention [0003] The pre...
