  • Publication number: 20210129683
    Abstract: Controller determines an output limit value that defines an upper limit of a current or power recommended for suppressing cell deterioration based on a voltage, a current, and a temperature of each cell, and notifies host controller in electric vehicle of the determined output limit value. When electric vehicle climbs a hill, controller calculates a current value or power value to be discharged from power storage unit, the current value or power value being required for electric vehicle to climb the hill at a speed not less than a set minimum speed, while suppressing an amount of deterioration of cells within an allowable range, and when the calculated current value or power value is larger than the output limit value, replaces the output limit value with the calculated current value or power value.

  • Publication number: 20200303929
    Abstract: The power conditioner determines possible total power and working individual power to be in a range that possible individual power of each of the power supply units is not exceeded. The possible total power is determined from the possible individual power, of each of the power supply units, determined based on the battery information detected by each of the unit controllers, collected by a master controller from each of the unit controllers. The working individual power is determined based on a power deviation indicating a difference of charging and discharging power between the power supply units. The power conditioner causes charging and discharging of each of the power supply units within the calculated working individual power.
