Abstract

The invention discloses a battery core fixing structure for an electric automobile. The fixing structure comprises an automobile chassis, a heat dissipation plate and a plurality of battery cores, wherein the heat dissipation plate is fixedly connected to the automobile chassis; the battery cores are arranged on the heat dissipation plate through a fixing material; each of the battery cores is a soft-packed battery core or a steel-shell battery core; and when each of the battery cores is the soft-packed battery core, a gap with 1-10 mm is reserved between the soft-packed battery cores. According to the battery core fixing structure for the electric automobile and the electric automobile provided by the invention, the heat dissipation efficiency is high; more battery cores can be arranged on the automobile chassis, and the energy density is high.

Description

technical field

[0001] The invention relates to the technical field of batteries, in particular to a cell fixing structure of an electric vehicle and the electric vehicle. Background technique

[0002] A cell refers to a single electrochemical cell containing positive and negative electrodes, including soft pack cells and steel shell cells. Battery PACK generally refers to a single battery component. For example, two batteries are connected in series to form a specific shape according to customer requirements. We call it battery PACK, which generally refers to a combined battery. A battery module is a multiple battery PACK composed of several to hundreds of battery cells connected in parallel and in series. In addition to the mechanical design part, a battery management system and a thermal management system can be added to form a relatively complete battery pack system. .

[0003] With the gradual popularization of electric vehicles, people pay more and more attention to ...
