  • Electric power source control apparatus, electric power source control method, and vehicle including electric power source control apparatus
    Patent number: 8247123
    Abstract: An electric power source control apparatus (50) includes a required electric power decision portion that receives an operation input signal from an outside of an electric power source (20), and decides an amount of electric power required of the electric power source (20), in accordance with the operation input signal; and an electric power source operation portion that operates the electric power source (20) in accordance with the amount of the required electric power. The electric power source operation portion limits an amount of electric power used for heating when the amount of the required electric power is larger than an amount of electric power that can be supplied by the electric power source, during heating.
