Description
technical field [0001] The invention relates to a nickel hydrogen battery charging circuit, in particular to a backup battery charging circuit. Background technique [0002] When charging the Ni-MH battery, the characteristics of the battery itself should be considered, and the charging and discharging should be carried out according to the characteristics of the rechargeable battery; in the past, when charging the rechargeable (Ni-MH) battery, the characteristics of the battery itself were not analyzed, which would cause The overcharging and overdischarging of the battery greatly reduces the life of the battery; so a backup battery charging circuit is urgently needed to solve the above problems. Contents of the invention [0003] The purpose of the present invention is to provide a spare battery charging circuit to address the shortcomings of the prior art. The spare battery charging circuit can well prevent the battery from being overcharged and overdischarged, and avoid...
