Problems solved by technology

However, the temperature signal and voltage signal in the existing battery module structure are all connected to the processing unit by wires from the corresponding collection points. When there are too many wiring harnesses in the module structure, it is difficult to identify the corresponding functions of each wire, and it is easy to be confused during installation and maintenance, resulting in assembly errors and even burning out the corresponding components

Abstract

The invention provides a battery module structure, which comprises a plurality of battery packs, a confluence board and a collecting board, wherein each battery pack consists of a plurality of single batteries in parallel distribution; the confluence board comprises an upper surface and a lower surface opposite to the upper surface; the battery packs are arranged on the upper surface of the confluence board and are electrically connected with the confluence board; the collecting board is arranged on the lower surface of the confluence board; a voltage collecting terminal and a temperature sensor are arranged on the collecting board; the voltage collecting terminal is in an insertion pin shape; the confluence board is provided with a voltage collecting hole; the voltage collecting terminal passes through the voltage collecting hole; the temperature sensor is in a patch shape; the confluence board is provided with a temperature collecting hole; the temperature sensor is accommodated in the temperature collecting hole; the voltage collecting terminal collects voltage signals of the single batteries connected to the confluence board; the temperature sensor senses the temperature signals of the corresponding single batteries and converts the temperature signals into temperature electric signals.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of batteries, in particular to a battery module structure. [0003] 【Background technique】 [0004] In the application of lithium-ion batteries, multiple single cells are usually connected in parallel to form a battery pack, and then adjacent battery packs are connected in series to form a battery module. A battery management system is installed in the battery module. Voltage signal and temperature signal, and control the discharge circuit and equalization circuit, so as to effectively protect the battery module. However, the temperature signal and voltage signal in the existing battery module structure are all connected to the processing unit by wires from the corresponding collection points. When there are too many wiring harnesses in the module structure, it is difficult to identify the corresponding function of each wire, and it is easy to be confused during installation and maintenance, resulti...
