Classification: CPC G  H  Y | IPC G  H

Claim 10:
11. The detection apparatus according to claim 9, wherein the specified moment comprises a first moment and a second moment;
the battery capacity difference comprises a first battery capacity difference corresponding to the first moment and a second battery capacity difference corresponding to the second moment;
wherein the calculation module is configured to:
calculate a target difference between the second battery capacity difference and the first battery capacity difference, and determine a ratio of the target difference to duration between the second moment and the first moment (ΔT1) as a leakage current value of the target battery; and
calculate an average voltage value of the target battery within the duration, and determine a micro-short circuit resistance of the target battery with reference to the leakage current value; and
wherein the determining module is configured to:
if a value of the micro-short circuit resistance obtained by the calculation module is less than a preset resistance threshold, determine that the target battery is micro-short-circuited.
