Inter-backup type lithium battery management system

Abstract

The invention discloses an inter-backup type lithium battery management system. An electric quantity real-time detection module is used for monitoring the electric quantity information of a first power supply lithium battery and a second power supply lithium battery in real time and inputting the collected electric quantity information of the first power supply lithium battery and the second power supply lithium battery into an electric energy supply switching module and a lithium battery charging management module; the electric energy supply switching module is used for selecting a lithium battery which is used for supplying power to a power utilization device, and simultaneously the lithium battery charging management module is used for charging the under-current lithium battery; a solar energy conversion unit, a wind energy conversion unit and a mechanical shock conversion unit in a power generation module are used for converting solar energy, wind energy and mechanical energy into electric energy, thus the purposes of energy conversation and environmental protection are realized; simultaneously, display screens are arranged on the electric quantity real-time detection module and the lithium battery charging management module so that the work state of the lithium battery is known timely; display interfaces of the display screens are simple and clear; and the inter-backup type lithium battery management system has the advantages of increasing the sustainability of power supply, being simple in structure and strong in practicability and having higher popularization and application value.

Description

Technical field [0001] The invention belongs to the technical field of power electronics, and in particular relates to a mutual backup type lithium battery management system. Background technique [0002] Generally, smart devices and data acquisition devices in the wild environment need lithium batteries to supply power.
