Abstract:
PROBLEM TO BE SOLVED: To provide a vehicular power supply apparatus capable of reducing an energy loss due to circuit resistance and alleviating the load on a battery (e.g., deterioration of a cell) when a motor is supplied with electric energy, and improving the sustainability of a regenerative brake.SOLUTION: A vehicular power supply apparatus 1 includes: a first battery 21; a second battery 22 capable of discharging and charging more quickly than the first battery 21; a voltage variation device 3 for controlling step-up and step-down of a voltage of the second battery 22; and a motor 4 for functioning by receiving electric energy from at least either of the first battery 21 and second battery 22. The second battery 22 has a positive side parallel connected to the first battery 21 and a negative side serially connected to the voltage variation device 3.SELECTED DRAWING: Figure 1
