Abstract

The invention discloses a wireless communication-based distributed type automobile battery power supply control system and method. The wireless communication-based distributed type automobile batterypower supply control system comprises a vehicle-mounted ECU (electronic control unit) which is connected in a wireless mode with an enterprise monitoring server, and the enterprise monitoring server is connected with a wireless mode with a national monitoring server and connected with a database; the vehicle-mounted ECU is connected with a BMS (battery management system) master controller; the BMSmaster controller is used for establishing wireless connection with a quick-change battery pack according to the frequency point data of the database and acquiring the battery pack data of the quick-change battery pack, and the battery pack data is transmitted to the national monitoring server through the vehicle-mounted ECU and the enterprise monitoring serer. The wireless communication-based distributed type automobile battery power supply control system achieves real-time uploading of the battery pack data to the enterprise monitoring server and the national monitoring server and further achieves battery pack data monitoring. The quick-change battery pack is high in power storage capacity, good in portability and reliable and safe in electric connection, and through random frequency divided connection, achieves communication independence and small interference.

Description

technical field [0001] The invention relates to the technical field of new energy vehicle power batteries, in particular, a wireless communication-based distributed battery power supply control system and method for vehicles. Background technique [0002] New energy vehicles, especially pure electric vehicles, have become a hot spot in the development of the automotive industry. Existing pure electric vehicles use power batteries as power sources. Existing pure electric vehicles are mainly divided into plug-in type and quick-change type based on different charging methods. Among them, due to the limited number of power batteries of plug-in pure electric vehicles, the driving range of pure electric vehicles is limited. When pure electric vehicles need to travel for a long distance, they must be charged multiple times along the way. However, the existing plug-in pure electric vehicles generally take more than one hour to fully charge once, and the problem of low charging effi...
