Title:
BATTERY MODULE AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/259171
Kind Code:
A1
Abstract:
The present application provides a battery module and device, said battery module comprising a battery unit, comprising a battery top cover; a temperature measurement unit, comprising a temperature collection element which collects the temperature of the top cover of the battery top cover; a wiring harness panel, arranged on the battery top cover and comprising a wiring harness panel main board and a position-limiting structure arranged on the wiring harness panel main board, the position-limiting structure fitting with a temperature measurement unit so as to limit the position of the temperature measurement unit; a circuit board, arranged on the wiring harness panel and comprising a circuit board main board and an extension strip arranged on the circuit board main board, the temperature collection element being connected to the extension strip so as to transmit the collected temperature signal to the circuit board main board by means of the extension strip; an electrical connection tab, which connects different battery cells and which is arranged on the wiring harness panel, the temperature measurement unit being located between the electrical connection tab and the battery top cover, the electrical connection tab applying pressure to the temperature measurement unit so as to keep the temperature measurement unit joined to the battery top cover. The temperature collected by the temperature collection element in the battery module can more accurately reflect the true temperature inside the battery cell, helping to ensure the discharge power of the battery module.
