Modular detachable SMC composite molded battery pack for new energy automobile

Abstract

The invention provides a modular detachable SMC composite molded battery pack for a new energy automobile. The battery pack comprises a battery pack shell and a cover plate, two mounting baffles are mounted in the battery pack shell in a sliding manner; a battery accommodating cavity is formed between each mounting baffle and an inner wall of the battery pack shell; a battery module is mounted ineach battery accommodating cavity in a sliding manner; a locking mechanism is arranged at one end of each battery module; an insulating film is arranged above each battery module; each insulating filmis fixed between the mounting baffle and the inner wall of the battery pack shell through an adjusting mechanism; a plurality of conductive films are arranged at the bottom of each insulating film side by side; and two pressure mechanisms are set on the cover plate. According to the battery pack disclosed by the invention, the pull-out installation of the battery module is realized, the disassembly and assembly steps of the battery module are simplified, the time for installing the battery module by an operator is shortened, and the size of the battery accommodating cavity can be adjusted according to the size of the battery module such that the battery pack can be adapted to the battery modules with different capacity specifications.

Description

technical field [0001] The invention relates to the technical field of power batteries for new energy vehicles, in particular to a modular detachable SMC composite molded battery pack for new energy vehicles. Background technique [0002] New energy vehicles refer to the use of unconventional vehicle fuels as power sources (or the use of conventional vehicle fuels, the use of new vehicle power devices), the integration of advanced technologies in vehicle power control and driving, and the formation of advanced technical principles and new features. Currently, electric vehicles using lithium-ion batteries are the most widely promoted. Lithium-ion battery is a secondary battery (rechargeable battery), with high energy density, high average output voltage, small self-discharge, excellent cycle performance, fast charge and discharge, charging efficiency up to 100%, high output power, and long service life , does not contain toxic and harmful substances, and is called a green ba...

Problems solved by technology

[0003] An adjustable battery pack is proposed in the Chinese invention patent with the patent application number 201620711507.2. The main problem in this patent is: when the battery pack needs to be replaced in this patent, the battery pack cover, the battery pack bracket and the battery pack need to be replaced. The battery pack in the battery pack housing can only be taken out for replacement after the contact plates are removed in sequence, and the disassembly operation is very troublesome; and after the battery contact plate, battery pack bracket, and battery pack cover are reinstalled and fixed, it is easy to cause the battery contact plate to be damaged. The contacts on the battery pack are not aligned with the battery cells in the battery pack, which affects the normal use of the battery pack
