<p><P>PROBLEM TO BE SOLVED: To provide a power supply system for vehicle which can utilize regenerative energy in a vehicle more effectively. <P>SOLUTION: In a power supply system for vehicle equipped with a generator 40 which is driven with regenerative energy in a vehicle, a second battery 20 for exclusively storing electrical power generated from the generator 40 is provided separately from a first battery 10 connected with the electric load 50 of the vehicle and principally supplying power to the electric load 50. Since the remaining amount of the second battery 20 does not have an impact on the drive characteristics of the electric load 50, the remaining amount of the second battery 20 may be decreased as much as possible, and the charging amount (amount of regenerative energy) of the second battery 20 can be increased by a corresponding amount. On the other hand, power of the second battery 20 is utilized for both driving of the electric load 50 and charging of the first battery 10 via a charging path 60, and thereby energy is utilized more effectively. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
