電源システムの制御装置
Document Type and Number:
Japanese Patent JP7204399
Kind Code:
B2
Abstract:
To make it possible to appropriately secure a cruising distance when a voltage converter fails in a power supply system including two or more power storage devices.SOLUTION: A power supply system includes: a first power storage device 10 connected to a driving motor 50; and a second power storage device 20 connected to the first power storage device 10 via a voltage converter 30. When the voltage converter 30 fails, the first power storage device 10 and the second power storage device 20 are electrically connected via the voltage converter 30. When the voltage converter 30 fails and when a difference between a voltage V1 of the first power storage device 10 and a voltage V2 of the second power storage device 20 is larger than a reference difference, a control device of the power supply system controls a current flowing from the power storage device connected to a load to the load connected to the first power storage device 10 or the second power storage device 20 so that a rate of decrease in the difference between the voltage of the first power storage device 10 and the voltage V2 of the second power storage device 20 increases.SELECTED DRAWING: Figure 4
