Problems solved by technology

Therefore, if the method of discharging and charging at the same time is adopted, it will cause some batteries in the battery pack to start charging when they are not fully discharged, which reduces the service life of the battery pack, and also brings a lot of trouble to the user when charging. Inconvenience

Abstract

The invention relates to a power supply technology of terminal equipment and discloses a charge-discharge method of a battery pack and a system thereof, which can prolong the service life of battery units in the battery pack. In the invention, when in discharge, the battery units in the battery pack are discharged one by one instead of being discharged together; and when in charge, the used-up battery units are charged one by one, i.e. the next battery unit is charged after the charge of the current battery unit is completed.

Description

technical field [0001] The invention relates to the power supply technology of terminal equipment, in particular to the charging and discharging technology of battery packs. Background technique [0002] Conventional battery refers to a cup, tank or other container or part of a composite container that contains an electrolytic solution and metal electrodes to generate an electric current. As technology advances, batteries generally refer to small devices that can generate electricity. Today, there are more and more types of batteries, and the types are becoming more and more extensive, such as zinc-manganese batteries (containing zinc and manganese dioxide), zinc-mercury batteries (containing zinc and mercury oxide), lithium batteries, cadmium-nickel, Iron-nickel, zinc-silver, zinc-air and lithium-iron sulfide and lead-acid batteries, etc. And, in order to improve the service life of the battery and provide more energy, the concept of a battery pack is further proposed. ...
