Abstract

The invention relates to the technical field of battery management, and discloses a distributed lithium battery control system. The distributed lithium battery control system comprises a hardware system, which is composed of a main control module, a total voltage acquisition module, a single battery voltage acquisition module, a high-voltage control module, a low-voltage control module, a total voltage sensor, a first CPLD control module, a first optical coupling relay, a sub-voltage sensor, a high-voltage equalizing module, a low-voltage adaptation module, a first CAN communication module anda second CAN communication module; the main control module is in communication connection with the total voltage acquisition module and the single battery voltage acquisition module through the firstCAN communication module; and the second CAN communication module is in communication connection with the high-voltage control module and the low-voltage control module. The invention further discloses a control method of the distributed lithium battery control system. By means of the distributed lithium battery control system and method in the invention, the problem that the lithium battery control system cannot effectively reduce the monitoring cost while effectively monitoring the working voltage of any single battery in a lithium battery module group can be solved.

Description

technical field [0001] The invention relates to the technical field of battery management, in particular to a distributed lithium battery control system and method. Background technique [0002] Because of its many good advantages, lithium batteries have gradually replaced traditional nickel-cadmium batteries and lead-acid batteries, and have become the current mainstream power batteries. Inside the lithium battery, due to its complex chemical reaction, while people are constantly improving the performance of the lithium battery itself, they are also conducting continuous research on the management technology and use of the lithium battery to increase the service life of the lithium battery and improve the efficiency of the lithium battery. Maximize the performance of lithium batteries. [0003] At present, lithium battery management systems mainly have two architectures: centralized and master-slave distributed. Among them, the high-voltage processing unit and data acquis...
