A battery state detection device detects a battery state and includes: a first permissible current calculating unit configured to calculate a first permissible current of a battery based on a voltage of the battery detected by a voltage detecting unit; a second permissible current calculating unit configured to calculate a second permissible current of the battery without using the voltage of the battery; and a correction unit configured to compare the first permissible current and the second permissible current and to perform a predetermined correction process on the basis of the comparison result.
