Embodiment 1
[0043] see Figure 4Embodiment 1 provided for the present invention. The aluminum-air battery stack 401 is composed of 12 pieces of aluminum-air battery cells superimposed and assembled. The platform voltage is 13.2 volts. The initial storage capacity of each single aluminum-air battery is 2.2Kwh, and the total storage capacity of 12 pieces reaches 26Kwh.
[0044] When the electrolyte in the aluminum-air battery stack 401 is in operation, the electrolyte controller 403 is used for regular circulation. There are various sensors and solenoid valves in the electrolyte controller 403. At the same time, according to the operating state, the electric pump is instructed to control the liquid level, liquid temperature, start-up liquid injection, shutdown liquid return, etc., so that the aluminum-air battery stack 401 can be stable for a long time under the control of the electrolyte controller 403 run.
[0045] The aluminum-air battery stack 401 is sealed with a sealing cover, and t...

Description
technical field [0001] The invention relates to the technical field of batteries, in particular to a composite aluminum-air battery system. Background technique [0002] With the vigorous development of the automobile industry, the energy consumption of automobiles is increasing year by year. Therefore, environmentally friendly and energy-saving electric vehicles will gradually become popular. However, as the energy storage system of electric vehicles, traditional batteries, especially lithium-ion batteries, have disadvantages such as high price, low specific energy, and difficulty in recycling, which have become the biggest bottleneck restricting the development of electric vehicles. Electric vehicle power batteries require high power output, high current charging and discharging, large storage capacity, safe and reliable use, good environmental protection, and high cost performance. The current mainstream battery systems include lithium-ion batteries, hydrogen fuel cells,...
