Claim 4:
5. The method according to claim 1, 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 determining a reference battery parameter value of the virtual reference battery at the specified moment based on the target battery parameter value and the reference initial battery parameter value comprises:
determining 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 determining 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
determining 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; and
wherein calculating a difference between the target battery parameter value and the reference battery parameter value, and determining, based on the difference, that the target battery is micro-short-circuited comprises:
calculating a voltage difference between the target terminal voltage value and the reference terminal voltage value, and determining, based on the voltage difference, that the target battery is micro-short-circuited.
