<p><P>PROBLEM TO BE SOLVED: To provide a power controller that reduces the possibility of battery death. <P>SOLUTION: A power supply control ECU 1 includes a voltage decision unit 11, which evaluates the level (=voltage level) of electric energy accumulated in a battery 22, based on a signal that shows the value of a terminal voltage from a voltage sensor 23, a car velocity decision unit 12, which evaluates the level (=cancel decision value) of power generated by an alternator 21, based on a signal that shows the value of car velocity from a car velocity sensor 24, a priority setter 13, which sets one priority level from among three stages of priority levels, based on the voltage level decided by the voltage decision unit 11 and the cancel decision value decided by the car velocity decision unit 12, and a power supplier 14, which supplies power from a battery 22 (or an alternator 21) to an electric load to which priority level over the priority level set by the priority setter 13 is set. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
