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, wiring harness boards, circuit boards, pressing parts and heating components. The battery includes the top cover. The wiring harness plate is provided on the top outer side of the top cover. The circuit board is arranged on the side of the harness board away from the battery. The compression piece is mounted on the harness plate. The temperature collecting component includes a thermistor, and the thermistor is electrically connected with the circuit board. The pressing part presses the thermistor of the temperature collection component, so that the thermistor is pressed against the top cover. In the battery module provided by the above technical solution, the temperature collection component collects the temperature of the battery top cover, the temperature transmission path is short, the temperature transmission response is fast, the temperature loss is small, and the measurement is accurate.

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...
