POWER MANAGEMENT DEVICE
Document Type and Number:
Japanese Patent JP2022139460
Kind Code:
A
Abstract:
To charge a battery while suppressing performance deterioration of a fuel cell.SOLUTION: A power management device 100 of a fuel-cell vehicle V includes: a charging power acquisition unit 11 that acquires chargeable power that can be received by a battery 2; a generated power acquisition unit 12 that acquires minimum generated power of a fuel cell 1; a power generation control unit 13 that controls output power of the fuel cell 1; and a charging control unit 14 that charges the battery 2. In a case that the minimum generated power is greater than the chargeable power when the battery 2 is charged, the power generation control unit 13 controls the fuel cell 1 such that the output power becomes equal to or higher than the minimum generated power, and the charging control unit 14 supplies the output power of the fuel cell 1 to the battery 2 and a brake resistor 4 to charge the battery 2.SELECTED DRAWING: Figure 1
