Cadmium-nickel battery management system

Abstract

The invention discloses a cadmium-nickel battery management system which comprises a signal acquisition unit, a communication unit, a data storage unit and a management control unit; the signal acquisition unit is used for acquiring and storing the total voltage, monomer voltage, current and battery temperature of a cadmium-nickel battery; the communication unit is connected with a train network to upload battery data, download data during maintenance of the battery management system, and update programs; the data storage unit is used for storing key operation data of the battery management system and historical operation data of the battery management system; and the management control unit is used for carrying out abnormity detection and early warning on the storage battery pack, realizing charging and discharging control and SOC calculation, sending corresponding instructions to the signal acquisition unit, the communication unit and the data storage unit, and receiving informationfed back by each unit at the same time. The cadmium-nickel battery management system can solve the problems that a traditional cadmium-nickel battery has no data processing capacity and cannot be managed due to the fact that the traditional cadmium-nickel battery is directly in butt joint with a subway system.

Description

technical field [0001] The invention relates to the technical field of nickel-cadmium battery management, in particular to a nickel-cadmium battery management system. Background technique [0002] With the increasing demand for fast and safe rail transit travel methods and the continuous evolution of intelligent driving technology, the technology of intelligent unmanned subway rail trains has gradually received attention. The premise of intelligentization is the real-time collection and transmission of data, and as a The nickel-cadmium battery pack, which is an important supporting component in the rail train power system, needs a corresponding battery management system to realize accurate collection and monitoring of battery data and provide basic data for transmission to the train central control system. How to design the battery management system corresponding to the nickel-cadmium battery pack that meets the requirements of rail transit has become a bottleneck that restr...
