Title:
VARIABLE VOLTAGE CHARGING SYSTEM AND METHOD FOR VEHICLE
Document Type and Number:
Japanese Patent JP2021100367
Kind Code:
A
Abstract:
To provide vehicle charging systems and methods configured to provide at least two different charge voltage outputs to charge different power storage devices on a vehicle.SOLUTION: A variable voltage charging system 100 for a vehicle includes an alternator 116 connected to an engine and configured to alternately output at least a low charge voltage to charge a low voltage power storage device and a high charge voltage to charge a high voltage power storage device. A switch is configured to switch between connecting the alternator to the low voltage power storage device 102 and connecting the alternator to the high voltage power storage device 108. An ECM 112 is configured to control operation of the alternator and switch between at least a low voltage mode and a high voltage mode. At low engine speeds and other low voltage mode conditions, the alternator operates in a low charge voltage output mode and the switch connects the alternator to the low voltage power storage device. At higher engine speeds above an engine speed threshold, the alternator operates in the high voltage mode to output a high charge voltage and the switch connects the alternator to the high voltage power storage device.SELECTED DRAWING: Figure 2
