Lithium battery charge and discharge management system and method

Abstract

The invention provides a lithium battery charge and discharge management system. Lithium battery is a single-section lithium battery. The lithium battery charge and discharge management system comprises a lithium battery charge and discharge management module, a lithium battery voltage over-discharge protection module, a lithium battery discharge overcurrent protection module and a boosting module. Correspondingly, the invention further provides a lithium battery charge and discharge management method. The lithium battery charge and discharge management system and the lithium battery charge and discharge management method, which are provided by the invention, realize the application management of the single-section lithium battery, overcome the difference among the lithium batteries caused by series connection of the lithium batteries in the prior art, and greatly prolong the service life of the lithium batteries. Meanwhile, the lithium battery charge and discharge management system can be protected by the lithium battery voltage over-discharge protection module and the lithium battery discharge overcurrent protection module, so that a lithium battery protection panel is not required to be additionally provided in the lithium battery charge and discharge management system. Therefore, the lithium battery charge and discharge management system and the lithium battery charge and discharge management method have the advantages of safety, reliability, simplicity in realization, low cost, and easiness in lithium battery charge and discharge management system and the lithium battery charge and discharge management method.

Description

technical field [0001] The invention relates to the application field of lithium batteries, in particular to a charging and discharging management system and method for lithium batteries. Background technique [0002] Lithium batteries are widely used in mobile communication equipment, such as repeaters, network signal monitors and other equipment monitoring systems. The power supply voltage of these equipment monitoring systems is usually 9V or above, while the voltage of a single lithium battery is usually 4.2V. The minimum power supply voltage is about 3.6V, which cannot meet the power supply requirements of the equipment monitoring system. For this reason, the usual practice is to use multiple lithium batteries in series to meet the power supply voltage requirements of the equipment monitoring system. As the number of discharges increases, the difference between each lithium battery in series will become larger and larger, resulting in inconsistent charging time of each...
