Embodiment 1
[0017] Such as figure 1 as shown, one A fast charging device for a lead-acid battery, comprising an electrolyte input acid tank 1, an electrolyte output acid tank 2, and a high-density electrolyte acid tank 3, and the high-density electrolyte acid tank 3 passes through the set first and second pipelines The electrolyte input acid tank 1 and the electrolyte output acid tank 2 are respectively connected, and the electrolyte input acid tank 1 and the electrolyte output acid tank 2 are respectively connected to the battery 9 through the set input and output pipelines; the first and second pipelines , and the input and output pipelines are respectively provided with control valves (namely: input and output pipeline control 5, 6, first and second pipeline control valves 4, 7); electrolyte input acid tank 1, high-density electrolyte acid tank 3 are respectively provided with water injection pipelines 10, wherein the high-density electrolyte acid tank is also provided with acid i...
Embodiment 2
[0026] A fast charging method, comprising the steps of:
[0027] (1) The input and output pipes for inputting the electrolyte into the acid tank 1 and outputting the electrolyte into the acid tank 2 are inserted into the casing of the battery 9 as described above. Under the control of the controller 8, the first pipeline control valve 4 is opened, and the high Density electrolyte acid tank 3 quantitative output density is 1.4 g / cm 3 electrolyte solution to the electrolyte input acid tank 1, after the delivery is completed, the first pipeline control valve 4 is closed, and the electrolyte solution is input into the acid tank 1 to adjust the electrolyte solution to a density of 1.1 g / cm 3 , and then the input pipeline control valve 5 is opened, and the electrolyte solution is delivered to the battery 9 quantitatively, and then left to stand for 2 hours;
[0028] (2) Charge with a current of 0.20C / n ampere / piece for 3 hours, then charge with a current of 0.30C / n ampere / piece for...
Embodiment 3
[0032] A fast charging method, comprising the steps of:
