Abstract

The invention discloses a state monitoring module for a mobile type power bank battery management system. The state monitoring module is formed by connecting multiple measuring units in series through a CAN bus; each measuring unit comprises a CPU, a voltage detection unit and a temperature detection unit. The state monitoring module for the mobile type power bank battery management system can be used for monitoring state parameters of a battery pack at the charging stage, the discharging stage, the storage stage and the transportation state, such as charging current, discharging current, voltage, temperatures, pressure and leakage current parameters.

Description

technical field [0001] The invention relates to a state monitoring module of a mobile power bank battery management system. Background technique [0002] The existing infrastructure established for electric vehicles is mainly fixed and cannot be flexibly moved. In the actual use of electric vehicles, due to human negligence or equipment failure, sometimes the electric vehicles on the way cannot continue to drive to the charging and swapping point due to the exhaustion of power. In view of the above unexpected situation, it is very necessary to develop a freely movable charging unit to supplement energy for electric vehicles, so the concept of a mobile charging treasure specially for electric vehicles is proposed. [0003] The mobile power bank is an emergency power supply device for a freely movable electric vehicle, and the battery energy storage unit is an important part of the mobile power bank. Due to the influence of manufacturing process, working temperature, aging, ...
