Abstract

The invention discloses a battery heating system of an electric automobile, and aims to provide a battery heating system which is uniform in heat distribution, high in heating efficiency and good in heating consistency for each battery module. The battery heating system comprises a plurality of mounting plates and a plurality of groups of battery modules, wherein a plurality of single batteries are arranged in each battery module; the battery modules are arranged in the corresponding mounting plates respectively, and are fixed in a battery box through the mounting plates; a plurality of electric heating plates are arranged in each battery module, and each electric heating plate is arranged between every two adjacent single batteries respectively; a heat transfer heat-conducting fin is arranged between each mounting plate and each battery module, the upper surface of the heat transfer heat-conducting fin is jointed with the bottom surface of each single battery in each battery module, and the lower surface of the heat transfer heat-conducting fin is jointed with the inner bottom surface of each mounting plate; and a soaking heat-conducting fin is arranged below each mounting plate, and the outer bottom surface of each mounting plate is jointed with the upper surface of each soaking heat-conducting fin.

Description

technical field [0001] The invention relates to a battery of an electric vehicle, in particular to a battery heating system of the electric vehicle. Background technique [0002] Due to the characteristics of the battery itself, when the temperature of the battery is below zero, it is forbidden to charge the battery from a safety point of view; this has limited the use of electric vehicles using batteries as power sources in low temperature areas. In order to solve the above problems, current battery manufacturers often use heating devices outside the battery module to heat the entire battery module. The battery module is usually composed of several battery cells; therefore, the heating device heats the battery cells inside the battery module unevenly, and the battery cells on the side close to the heating device are heated first, and then the heat can be dissipated It is gradually conducted to the battery cells located inside; this leads to the problem of low heating effic...
