Problems solved by technology

[0005] The inventors have found that there are at least the following problems in the prior art: due to the limitation of the internal space size of the battery module, and considering the influence of manufacturing and cost, the width and thickness of the connecting piece cannot be made very large
Under high-power working conditions, due to the limitation of the over-current area of ​​the connecting piece, the temperature of the connecting piece will rise sharply, while the temperature inside the battery will rise slowly. The temperature difference between the two is huge, which will cause the battery module to advance Limit power, which affects the discharge power of the battery module

Abstract

The invention discloses a battery module, relates to the technical field of batteries and is used for optimizing the structure of the battery module. The battery module includes batteries, connection sheets, wiring harness boards and heating components. The battery includes electrode terminals and a top cover. The connecting piece is fixed to the electrode terminal; the wire harness plate is arranged on the top outside of the top cover, and is provided with a mounting part and an elastic pressing part. The heating component is installed on the installation part and is located between the wiring harness plate and the top cover. Wherein, the elastic pressing part is in contact with the connecting piece, and the temperature collection component is in contact with the top cover. In the battery module provided by the above technical solution, the heating component is installed on the installation part of the wiring harness board, and the top cover of the heating component abuts, and the heating component directly abuts against the top cover of the battery. The temperature transfer path is short and the temperature response speed is fast.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a battery module. Background technique [0002] The normal working temperature of the battery module is between -30°C and 55°C. If the limit temperature is exceeded, the battery module will limit the discharge power to realize the safety protection of the battery module. [0003] In the related art, the temperature of the battery module is collected in the following way: the temperature on the connecting piece is collected through a thermistor arranged on the flexible circuit board, and the temperature of the connecting piece is used as the internal temperature of the battery. In actual situations, the temperature on the connection plate is high, while the temperature inside the battery is low. If the difference between the two is large, the battery module will limit the power in advance, which will affect the performance of the battery module. [0004] At present, all vehicle...
