Abstract

The application provides a battery module, including: a battery unit, including a battery top cover; a temperature measurement unit, including a temperature-collecting element for collecting the temperature of the battery top cover; a wiring harness board, arranged on the battery top cover, including a wiring harness board main board And the limit structure arranged on the main board of the wiring harness board, the limit structure cooperates with the temperature measuring unit to limit the position of the temperature measuring unit; the circuit board is arranged on the wiring harness board, including the main board of the circuit board and the extension set on the main board of the circuit board The temperature collection element is connected to the extension strip to transmit the collected temperature signal to the main board of the circuit board through the extension strip; the electrical connection piece is connected to different battery units, and is arranged on the wiring harness board, and the temperature measurement unit is located between the electrical connection piece and the battery top cover. Between them, the electrical connecting piece exerts pressure on the temperature measuring unit to keep the temperature measuring unit and the battery top cover in close contact. The temperature collected by the temperature-collecting element in the battery module can more accurately reflect the real temperature inside the battery unit, which is beneficial to ensure the discharge power of the battery module.

Description

technical field [0001] The present application 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 temperature exceeds this range, the battery module will limit the power to realize the safety protection of the battery module. [0003] In the temperature collection structure of the battery module known by the applicant, the temperature on the electrical connection sheet is collected through the metal sheet, and transmitted to the temperature sensor as the temperature collection element, and the temperature of the electrical connection sheet is regarded as the temperature inside the battery unit. [0004] In the process of realizing this application, the inventor found that the conventional temperature collection structure of the battery module has the following disadvantages: [0005] The size of the space inside the battery module...
