Battery pack information collecting system

Abstract

The invention relates to the technical field of electric vehicle batteries, and provides a battery pack information collecting system. The system comprises a battery pack, and two ends of positive andnegative electrodes of a battery pack are respectively connected with positive and negative interfaces. The battery pack includes a plurality of battery groups. The battery groups are arranged in rows. The battery group is composed of a plurality of battery cells connected in series, and the battery cells in the adjacent rows are arranged in an aligned manner. The battery groups in the same row are sequentially connected in series, and the battery cells adjacent up and down in the same battery group are connected in parallel synchronously. The system also includes a BMS, a host computer and aplurality of acquisition strips. The BMS is separately electrically connected to the acquisition strip, the positive and negative interfaces, and the host computer. The acquisition strip is arrangedon the battery pack to collect status information of the battery pack. The BMS monitors and manages a battery under the jurisdiction in a concentrated manner, and transfers data to the host computer for real-time monitoring. A simpler cable arrangement method is designed, and a simple information collection and management method is designed, so as to facilitate real-time monitoring of battery packworking states.

Description

technical field [0001] The invention relates to the technical field of electric vehicle batteries, and more specifically, to a battery pack information collection system. Background technique [0002] Traditional automobiles mainly consume oil resources, and oil resources are limited. It is imminent to improve energy utilization efficiency and develop new alternative energy sources. Faced with the increasingly prominent energy pressure and air pollution problems brought about by the development of the automobile industry, the development of electric vehicles has become a major trend in the development of the automobile industry. Pure electric vehicles have the advantages of environmental protection, energy saving and no air pollution, and have gradually become a new trend in the development of automobiles. [0003] At this stage, the mileage of electric vehicles still cannot meet the requirements of the mainstream public. The quality of vehicle power battery packs is the ma...

[0003] At this stage, the mileage of electric vehicles still cannot meet the requirements of the mainstream public. The quality of vehicle power battery packs is the main factor affecting the development of electric vehicles. and safety is paramount

Currently commonly used battery packs are difficult to achieve flexible series-parallel connection of batteries. The information collection method is to use the battery management system to realize the collection of battery pack charge and discharge status information. Flexible series-parallel combination of battery packs lacks effective information collection methods and systems
