Document Type and Number:
Japanese Patent JP7119728
Kind Code:
B2
Abstract:
To provide a power supply device of a vehicle capable of switching a regenerative-charged battery with a simple configuration and high efficiency.SOLUTION: A power supply device of a vehicle includes an electric motor (14) which generates power for driving wheels (11) by receiving power supply from a battery (20) and can regenerate and charge the battery by converting rotation energy of the wheels into the power. The power supply device includes a first battery (21) and a second battery (22) which has larger internal resistance than that of the first battery, as the battery, and includes a charging branch section (24) which branches a charging destination of regenerative charging into the first battery and the second battery. When the first battery reaches a first charging amount (CM1) when the first battery is charged with a first voltage (V1), a power generation amount of the electric motor is changed and a charging voltage is gradually changed up to a second voltage (V2) lower than the first voltage. When the first battery reaches a second charging amount (CM2), the second battery is charged with the second voltage through the charging branch section.SELECTED DRAWING: Figure 2
