Description

technical field [0001] The invention relates to a storage battery system, in particular to an airborne lithium ion storage battery system. Background technique [0002] The emergency backup power supplies used in the aviation field are mainly lead-acid batteries and nickel-cadmium battery packs. With the continuous improvement of aircraft tactical technical indicators, it is difficult for the weight, volume and discharge rate of the active battery packs to meet the requirements, which seriously restricts various The tactical and technical indicators of various aerospace vehicles have been further improved. In addition, due to the memory effect of nickel-cadmium batteries, the maintenance process is complicated and the service life is short, which has a great impact on the maintenance efficiency and cost of aircraft. [0003] Lithium-ion batteries are increasingly used in drones, aerospace vehicles and other aerospace fields. However, if the capacity, state of charge, se...
