Title:
FUEL CELL SYSTEM AND INDUSTRIAL VEHICLE ON WHICH FUEL CELL SYSTEM IS MOUNTED
Document Type and Number:
Japanese Patent JP2020123555
Kind Code:
A
Abstract:
To provide a fuel cell system capable of reducing a frequency of actuation of the fuel cell system in order to charge a low-voltage power storage device.SOLUTION: A fuel cell system comprises a fuel cell stack, a high-voltage power storage device, a low-voltage power storage device, a low-voltage side voltage measurement tool, a high-voltage side voltage measurement tool, and a control unit. The control unit makes the low-voltage power storage device be charged by making the high-voltage power storage device supply power to the low-voltage power storage device, when a second voltage value V2 is equal to or higher than a specified value Vth in the case that a first voltage value V1 is within a specified range Vr; and, when the second voltage value V2 is lower than the specified value Vth in the case that the first voltage value V1 is within the specified range Vr, makes the high-voltage power storage device be charged until the second voltage value V2 is equal to or higher than the specified value Vth and makes the low-voltage power storage device be charged by actuating the fuel cell stack by actuating an auxiliary machine.SELECTED DRAWING: Figure 3
