Battery module data acquisition structure and battery module with same

Abstract

The invention discloses a battery module data acquisition structure. The structure mainly comprises a left cover plate, a left protective cover, a right protective cover, a wire harness protective plate, a sampling wire harness, a module package cover and a right cover plate, the structure is characterized in that the sampling wire harness is installed in a groove in the upper end face of the module bag cover and fixed and protected through the wire harness protection plate, the left end of the sampling wire harness is connected with the left cover plate, the right end of the sampling wire harness is connected with the right cover plate, the left protection cover is connected with the left cover plate to protect the left end bent position of the sampling wire harness, and the right protection cover is connected with the right cover plate to protect the right end bent position of the sampling wire harness. The invention also discloses a battery module with the structure. According to the battery module data acquisition structure, the arrangement of the sampling wire harnesses is standard, tidy, concise and attractive; wiring harness connection is stable, connection loosening can beeffectively prevented, and battery operation safety is guaranteed; the wire harness is convenient to assemble and disassemble and easy to maintain; the battery module with the structure is simple in structure, reliable in performance and easy to maintain.

Description

technical field [0001] The invention relates to the technical field of automobile power batteries, in particular to a battery module data acquisition structure and a battery module with the structure. Background technique [0002] Lithium-ion batteries have many advantages that traditional batteries cannot match, such as high specific energy, high specific power, long life cycle, low self-discharge rate, energy saving and environmental protection, and have been widely used. In order to monitor the working status of the battery in the lithium battery pack, it is necessary to collect data such as voltage, current and temperature of the battery in real time, so as to provide a basis for the safety monitoring and life optimization of the battery system. The traditional method of doing this kind of data collection is to use multiple sampling lines to connect to the two poles of the battery and other related parts. Although this structure meets the requirements of collection, it h...

The traditional method of doing this kind of data collection is to use multiple sampling lines to connect to the two poles of the battery and other related parts. Although this structure meets the requirements of collection, it has the following disadvantages: 1. There are many and messy wiring harnesses, and there is no fool-proof Measures increase the risk of external short circuit and wrong connection. Once the above short circuit and wrong connection occur, it...
