Abstract

The invention discloses a lithium battery pack management system of a smart balance car. The system includes a first stage battery protection unit, a second stage battery protection unit, a third stage battery protection unit, a fourth stage battery protection unit, a charging unit, and a discharging unit which are successively connected. A lithium battery pack includes 20 lithium batteries which are in successive series connection. The charging unit and the discharging unit are in series connection, and are connected to a circuit where the lithium battery pack is at. The system manages and protects the lithium battery pack of the smart balance car through a multi-stage battery protection unit, reduces the chances of unbalanced charging and discharging or occurrence of abnormities caused by too many single lithium batteries in a lithium battery pack, and increases service life of the lithium battery pack.

Description

technical field [0001] The invention relates to the technical field of lithium battery management, in particular to a lithium battery pack management system for an intelligent balance vehicle. Background technique [0002] The smart balance car is also called the somatosensory car, the thinking car, and the camera car. Its operating principle is mainly based on a basic principle called "Dynamic Stabilization", using the gyroscope and acceleration sensor inside the car body to detect changes in the body attitude, and using the servo control system, The precise drive motors are adjusted accordingly to keep the system balanced. It is a new type of green and environmentally friendly product that modern people use as a means of transportation, leisure and entertainment. [0003] The lithium battery pack is an essential source of energy to drive the smart balance car. The endurance of the lithium battery pack is an important indicator for evaluating the performance of the smart...
