Classification: CPC G  H  Y | IPC G  H

Claim 11:
12. The detection apparatus according to claim 8, wherein the target battery parameter value comprises a target terminal voltage value of the target battery, a current value of the target battery, and a temperature parameter value of the target battery;
wherein the determining module is configured to:
determine a state-of-charge change value of the virtual reference battery within duration between the specified moment and the initial moment (ΔT0) based on the current value of the target battery and the temperature parameter value of the target battery, and determine a reference remaining battery capacity of the virtual reference battery based on an initial state-of-charge value of the reference initial battery parameter value of the virtual reference battery; and
determine a reference terminal voltage value of the virtual reference battery at the specified moment based on the reference remaining battery capacity and the current value;
wherein the calculation module is configured to:
calculate a voltage difference between the target terminal voltage value and the reference terminal voltage value; and
wherein the determining module is further configured to determine, based on the voltage difference obtained by the calculation module, that the target battery is micro-short-circuited.
