  • Patent number: 10821832
    Abstract: A battery control device includes a positional information acquiring unit, a deposition-risk-geographic-point storing unit, a determination unit, and a deposition-deterring-mode executing unit. The positional information acquiring unit is a processing unit that acquires positional information of a vehicle. The deposition-risk-geographic-point storing unit stores deposition risk geographic points. The determination unit determines whether or not the vehicle passes at least one of the deposition risk geographic points stored in the deposition-risk-geographic-point storing unit based on the positional information of the vehicle that is acquired by the positional information acquiring unit. The deposition-deterring-mode executing unit controls a battery based on a predetermined deposition-deterring mode, if the determination unit determines that the vehicle passes the at least one of the deposition risk geographic points.

  • Patent number: 10826101
    Abstract: A flow battery apparatus is provided with shunted currents repressed. The apparatus has a positive electrode device, a negative electrode device and a plurality of gas-gap devices. Gas-gap devices are separately set between branching channels and inlet and outlet manifolds of positive and negative electrodes. Each of the branching channels separately has an inserting tube to be inserted into one of the gas-gap devices. The diameter of the inserted vessel of gas-gap devices is bigger than the diameter of the inserting tube connected to a corresponding one of the branching channels. Thus, working liquids transferred to the positive and negative electrodes are segregated with coordination of the gas-gap devices. Only air spaces and discrete liquid drops are left between separated parts of the working liquids. Thus, shunted currents are repressed by preventing conductive paths from being formed between the positive and negative electrodes.
