Abstract
Systems and methods for supplying electrical power between two electric energy storage devices are disclosed. In one example, an electric isolation switch is held open after engine starting until a voltage of a first electric energy storage device and a voltage of a second electric energy storage device are within a threshold voltage of at least one predetermined voltage level.
Claims19
A power delivery method for a vehicle, comprising:
- reducing a voltage of a primary electric energy storage device via a controller after starting an engine via power supplied by the primary electric energy storage device and before closing an electric isolation switch that selectively couples the primary electric energy storage device to an accessory electric energy storage device.
A power delivery method for a vehicle, comprising:
- increasing a voltage supplied to an accessory electric energy storage device via a DC/DC converter via a controller after starting an engine via power supplied by a primary electric energy storage device and before closing an electric isolation switch that selectively couples the primary electric energy storage device to the accessory electric energy storage device.
