The function of a battery pack is to store the electrical energy emitted by the solar cell array when illuminated and to provide power to the load at any time. The basic requirements for the battery pack used in solar cell power generation systems are: ① low self discharge rate; ② Long service life; ③ Strong deep discharge ability; ④ High charging efficiency; ⑤ Less maintenance or no maintenance; ⑥ Wide working temperature range; ⑦ The price is low. At present, the batteries used in conjunction with solar cell power generation systems in China are mainly lead-acid batteries and cadmium nickel batteries. Equipped with lead-acid batteries of over 200Ah, fixed or industrial sealed maintenance-free lead-acid batteries are generally selected; For lead-acid batteries with a capacity of less than 200Ah, small sealed and maintenance free lead-acid batteries are generally selected
