  • Charging control device
    Patent number: 11539228
    Abstract: A CPU, when determining that the predicted minimum value of a limit value of charging power is not smaller than the minimum power of a charger, controls charging such that charging is performed in a normal mode, the normal mode being a mode in which a lower limit of a command value of supply power is the minimum power, when determining that the predicted minimum value is smaller than the minimum power, controls charging such that charging is performed in an estimation mode, that is a mode in which the lower limit of the command value is an estimated value of the minimum power of the charger, the estimated value being smaller than the minimum power, and controls charging such that charging is performed in the estimation mode by using, as the command value, power between a current limit value of the charging power and the estimated value.
