VEHICULAR HIGH POWER ELECTRICAL SYSTEM

摘要

A vehicle electrical system can include a high-power electrical bus that is controlled independently of an electrical bus connected to the vehicle battery. The high-power electrical bus may be supplied at least partially by a power converter (e.g., a DC/DC converter) that draws power from the vehicle battery, and which can at least partially decouple the high-power electrical bus from the vehicle battery. High-power electrical loads, such as an active suspension system, for example, may be powered by the high-power electrical bus.

主权项

1. An electrical system for a vehicle, comprising:
a power converter configured to convert a vehicle battery voltage at a first electrical bus into a second voltage at a second electrical bus, the second voltage being at least as high as the vehicle battery voltage; and an energy storage apparatus coupled to the second electrical bus; wherein at least one load is coupled to the second electrical bus, and wherein the power converter is configured to provide power from the first electrical bus to the at least one load and to limit a power drawn from the first electrical bus to no higher than a maximum power, and wherein, when the at least one load draws more power than the maximum power, the at least one load at least partially draws power from the energy storage apparatus.
