Power battery full-life-cycle tracking system capable of directly taking electricity from battery pack

Abstract

The invention discloses a power battery full-life-cycle tracking system capable of directly taking electricity from a battery pack. The power battery full-life-cycle tracking system is installed in a power battery box body, and comprises a power conversion module used for converting high-voltage electricity of a power battery into a conventional low-voltage power supply used by the device, a power management module used for supplying a continuous power source for all modules of the system, a power battery voltage acquisition module, a battery temperature acquisition module, a locating module, a controller area network (CAN) acquisition module, a communication module and a central processing unit (CPU) module, wherein the CPU module is connected with all the acquisition modules and the communication module, and is used for obtaining various information and sending all or part of the information to a cloud platform monitoring center by means of the communication module. The system provided by the invention can monitor the service condition of the power battery within a full life cycle, can obtain the voltage, electric quantity and temperature data of the power battery so as to judge the service life and the safety situation of the power battery, and is capable of accurately positioning so as to enable the waste power battery to be accurately recovered.

Description

technical field [0001] The invention belongs to the fields of environment, new energy, and communication, and in particular relates to a power battery life cycle tracking system and a use method that directly obtain power from a battery pack. Background technique [0002] The power battery is the power source that provides the power source for the tool, and mostly refers to the battery that provides power for electric vehicles, electric trains, electric bicycles, and golf carts. New energy vehicles are mainly composed of battery drive system, motor system, electronic control system and assembly. Among them, the motor, electronic control and assembly are basically the same as those of traditional cars, and the reason for the price difference lies in the battery drive system. From the perspective of the cost structure of new energy vehicles, the battery drive system accounts for 30-45% of the cost of new energy vehicles, and the power lithium battery accounts for about 75-85%...
