Title:
An electric power regeneration system for vehicles, and a voltage conversion device
Document Type and Number:
Japanese Patent JP6007869
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a power regeneration system for a vehicle, with which it is possible to efficiently use electric power based on a regeneration brake.SOLUTION: A power regeneration system for a vehicle includes: a power generator 11; a voltage conversion device 13 including a first power storage device 12 connected to the power generator 11 and a DC/DC converter 16 on whose input side the power generator 11 and the first power storage device 12 are connected; and a second power storage device 14 connected to an output side of the DC/DC converter 16, wherein an output voltage from at least one of the DC/DC converter 16 and the second power storage device 14 is supplied to a load 15, and the voltage conversion device 13 includes a control unit 17 that performs control so that when a charging rate of the first power storage device is higher than a first set value, an output voltage of the voltage conversion device becomes higher than a reference voltage, which is an output voltage of the second power storage device, and a potential difference increases and when the charging rate of the first power storage device is equal to or lower than the first set value, the output voltage of the voltage conversion device becomes equal to or higher than the reference voltage and the potential difference decreases.
