A battery pack internal short circuit detection method applicable to an electric vehicle includes checking a voltage change of a target battery based on voltages of a reference battery in two charging processes, and determining whether the target battery has an internal short circuit based on the voltage change of the target battery; or checking a voltage change of a reference battery based on voltages of a target battery in two charging processes, and determining whether the target battery has an internal short circuit based on the voltage change of the reference battery.
