  • Publication number: 20220185116
    Abstract: A power supply system includes power circuit which connects first and second batteries with a drive motor, and a management ECU which controls transfer of power between the batteries and the drive motor. The management ECU limits the output power of the second battery to no more than a second output upper limit, during combined output travel which drives the drive motor by way of the combined output of the first and second batteries. In addition, the management ECU sets the second output upper limit to a second maximum output of the second battery in the case of the first SOC of the first batter being greater than a remaining amount warning threshold, and sets the second output upper limit to a range extending upper limit which is smaller than the second maximum output, in the case of the first SOC being less than the remaining amount warning threshold.

  • Publication number: 20210243874
    Abstract: The object of the present invention is to suitably control a charging state of a human body all the time. A charging amount detection device 13 is worn by a human body and measures the surface potential of the human body. A static electricity control device 12 is worn by a human body and generates and discharges ions to the human body and thereby controls the static electricity on the human body. A mobile terminal 11 sets a control pattern of the static electricity on the human body that is suitable for a condition such as temperature and humidity for the static electricity control device 12 via short-range wireless communication. The static electricity control device 12 uses the set control pattern to perform feedback control of the static electricity on the human body by using the surface potential of the human body measured by the charging amount detection device 13.
