BATTERY RESISTANCE MEASUREMENT DEVICE, VEHICLE AND BATTERY RESISTANCE MEASUREMENT METHOD

A battery resistance measurement system measures an electrical resistance of a battery and comprises a determination unit and a measurement unit. The determination unit determines, based on whether a predetermined condition is satisfied, whether a target battery has switched from a charged state to a discharged state in which while the target battery receives supplied electric power the target battery outputs electric power larger than the supplied electric power. The measurement unit starts measuring the electrical resistance of the target battery at a time when the determination unit determines that the target battery is switched from the charged state to the discharged state.
