    • The vehicle-use power supply apparatus includes an alternator driven by an engine mounted on a vehicle to generate electric power in accordance with a command value, a battery electrically connected to the alternator to be charged by the alternator, and connected to electrical loads mounted on the vehicle to apply a power supply voltage to the electrical loads. The vehicle-use power supply apparatus further includes a first function of determining, as a power generation cost, an increase amount of fuel which the engine consumes for the alternator to generate electric power, and a second function of transmitting the command value to the alternator, the second function being configured to determine the command value on the basis of the power generation cost determined by the first function such that a change rate of the power supply voltage does not exceed a predetermined limit value.
    • 车用电源装置包括由安装在车辆上的发动机驱动的交流发电机,以根据指令值产生电力;电连接到交流发电机的电池,由交流发电机充电,并连接到安装在 车辆向电力负载施加电源电压。 车辆用电力供给装置还具备作为发电成本确定发动机为交流发电机消耗发电的燃料的增加量的第一功能,以及向发电机发送指令值的第二功能 所述第二功能被配置为基于由所述第一功能确定的发电成本来确定所述指令值,使得所述电源电压的变化率不超过预定限制值。
