The invention discloses a master-slave battery control system. The system comprises at least two battery packs. Each battery pack comprises a signal access module, a master control module, a battery core, a communication module and an information acquisition module, wherein the signal access module is used for acquiring a starting signal and sending the starting signal to the master control module; the master control module is used for receiving the starting signal, determining the current pack as a master pack, and sending master pack confirmation information to other battery packs through the communication module, so that other battery packs are determined as slave packs after receiving the master pack confirmation information; the information acquisition module is used for taking an acquired voltage of the battery core as a voltage of the current pack and sending the voltage to the master control module of the current pack; and the master control module of the master pack obtains avoltage of each slave pack, and when a difference value between the voltage of each slave pack and the voltage of the current battery pack is judged to be in a preset range, each slave pack is allowedto run. By applying the scheme, the use flexibility of the battery with the battery packs is improved. The invention further discloses a master-slave battery control method applied to the master packand the slave packs, which has the corresponding effects.
Description
technical field [0001] The invention relates to the technical field of batteries, in particular to a master-slave battery control system and method. Background technique [0002] In recent years, users have become more and more recognized for wireless products, and wireless devices such as home appliances and garden tools are more and more widely used. [0003] Batteries are an important link in wireless products. Considering that in some occasions, due to the increasingly high requirements of the product on power and the use time of the whole machine, some batteries adopt the design of parallel multi-battery packs. Parallel connection of multiple battery packs can improve the power supply. Current upper limit, prolong the use time. In addition, when designing in parallel, it is necessary to avoid the internal circulation caused by the excessive voltage difference between the battery packs. However, this parallel battery design is relatively simple in form, and generally o...
