Abstract: A power supply device of a hybrid car includes a driving battery 1 and a battery management system 2. The driving battery 1 can supply electric power to an electric motor 13 for driving the car. The battery management system 2 detects SOC of the driving battery 1, and transmits the detected SOC to the car. The battery management system 2 stores maximum SOC and minimum SOC relating to transmission of SOC to the car. When the detected SOC of the battery falls within a range between the maximum SOC and the minimum SOC, the detected SOC of the battery is transmitted to the car. When the detected SOC is not lower than the maximum SOC, the maximum SOC is transmitted to the car. When the detected SOC of the battery is not higher than the minimum SOC, the minimum SOC is transmitted to the car.

Abstract: A method of detecting a state-of-charge of a battery detects a current of a battery and a voltage of the battery, calculating a state-of-charge of the battery as a first state-of-charge based on an integration of the current of the battery thus detected, while calculating the state-of-charge of the battery as a second state-of-charge based on the voltage of the battery and calculating a synthetic state-of-charge obtained by taking a weighted mean of the first state-of-charge and the second state-of-charge as the state-of-charge of the battery, and weighting the weighted mean in order to increase weighting of the second state-of-charge in a region in which a capacity of the battery is increased and a region in which the capacity of the battery is reduced and to increase weighting of the first state-of-charge in other regions.
