Embodiment 1
[0021] A method for quickly judging the operating mileage of the battery module in the faulty Ni-MH battery pack is carried out according to the following steps:
[0022] ⅠTake one or more normal Ni-MH battery packs of the same type from N kinds of Ni-MH battery packs with different operating mileages. The operating mileage of the Ni-MH battery packs can be selected from 0 to L, and L is the rated total operating mileage of the battery pack. N is a natural number above 4, and the sample selection of the running mileage of the Ni-MH battery pack includes 0 and L, and several normal battery modules are respectively taken from the Ni-MH battery pack with the same running mileage, and the running mileage of the same running mileage is respectively measured. The charging state DC internal resistance of several battery modules is taken as the standard value of the charging state DC internal resistance of the running mileage battery module, and the charging state DC internal resistanc...
