Abstract

The invention provides a slave control module, a battery management system and a battery management method. The slave control module comprises a power supply circuit, a single chip microcomputer circuit, a communication circuit, a voltage acquisition circuit and a temperature acquisition circuit, wherein the single chip microcomputer circuit is respectively connected with the communication circuit, the voltage acquisition circuit and the temperature acquisition circuit; the power supply circuit is used for supplying power; the voltage acquisition circuit is connected with power batteries of apower battery pack through a voltage sensor and transmits the acquired voltage data to the single chip microcomputer circuit; the voltage acquisition circuit comprises 50 voltage monitoring points; the temperature acquisition circuit acquires the temperature of the power batteries through a temperature sensor and transmits the temperature data to the single chip microcomputer circuit; and the single chip microcomputer circuit transmits the voltage data and the temperature data to a main module through the communication circuit. By arranging the voltage monitoring points and the temperature monitoring points, the working states of all single batteries connected in series in the battery pack are monitored, thereby improving the working stability of the battery pack.

Description

Technical field [0001] The invention relates to the field of battery management, in particular to a slave control module, a battery management system and a battery management method. Background technique [0002] With the advancement of science and technology and the increasing demand for environmental protection, electric vehicles are becoming more and more popular in social life. An electric vehicle refers to a vehicle that uses an on-board power supply as a power source and uses motors to drive the wheels, so its impact on the environment is relatively small compared to traditional vehicles. The vehicle-mounted power battery pack is composed of hundreds of single cells combined in series and parallel, with a total voltage of several hundred volts and a charging current of several hundred amperes. The voltage and temperature of the battery during charging and discharging must be kept within a reasonable range. Due to the close connection between the single cells, the working s...
