Embodiment Construction

[0018] A battery control device according to an embodiment includes a current detection unit, a storage unit, and a state determination unit. The current detection unit detects the current flowing in the second battery among the first battery and the second battery connected in parallel and charged with a constant current. The storage unit stores an initial value of a current flowing through the second battery when the second battery is charged with the constant current at an early stage of use. The state determination unit determines the state of the first battery based on the current value detected by the current detection unit and the initial value stored in the storage unit.

[0019] Next, a battery control device, a battery system, and a mobile body according to an embodiment will be described with reference to the drawings.

Abstract

The present invention provides a battery control device, a battery system, and a moving body capable of judging the degree of deterioration of a plurality of storage batteries at low cost. The battery control device of the embodiment includes a current detection unit, a storage unit, and a state determination unit. The said current detection part detects the current which flows in the said 2nd battery among the 1st battery and the 2nd battery which are connected in parallel and are charged with a constant current. The storage unit stores an initial value of the current flowing in the second battery when the second battery is charged with the constant current in the initial stage of use. The state determination unit determines the state of the first battery based on the current value detected by the current detection unit and the initial value stored in the storage unit.

Description

[0001] This application claims priority to Japanese Patent Application No. 2015-235925 for which it applied on December 2, 2015, and uses the content for this application. technical field [0002] Embodiments of the present invention relate to a battery control device, a battery system, and a mobile body. Background technique [0003] Conventionally, battery systems mounted on mobile bodies such as vehicles, ships, and aircrafts sometimes use a plurality of storage batteries such as lead storage batteries and lithium-ion storage batteries in combination. If these storage batteries deteriorate due to long-term use, the electromotive force decreases and the output decreases. Therefore, it is necessary to determine the degree of deterioration of these storage batteries and to replace them with batteries that have reached their end of life (assumed service life). [0004] Although we know the technology of detecting the characteristics (voltage, current, impedance, etc.) The c...
