US Classification:

307 64, 307 43, 307 72, 295921

Abstract:

A multi-energy storage device system is provided that includes a first energy storage device (ESD) coupled to a direct current (DC) link. A bi-directional buck/boost converter includes an output channel coupled to the DC link and an input channel. A second ESD coupled to the input channel has a usable energy storage range defining an entire amount of usable energy storable therein. A database includes stored information related to a known acceleration event. A system controller is configured to acquire the stored information related to the known acceleration event and, during the known acceleration event, cause the buck/boost converter to boost the voltage of the second ESD and to supply the boosted voltage to the DC link such that after the known acceleration event, the state of charge of the second ESD is less than or substantially equal to a minimum usable energy storage state of charge.

Abstract:

A multi-energy storage device system includes an electric drive coupled to a load, a DC link coupled to the electric drive, and a bi-directional voltage converter having an output channel coupled to the DC link and an input channel. A first energy storage device (ESD) is coupled to the input channel, and a switch is coupled to the DC link and to a second ESD. A system controller causes the switch to couple the second ESD to the DC link for delivering energy stored in the second ESD to the electric drive. The system controller also causes the voltage converter to convert a voltage of the first ESD to a higher voltage and to deliver the higher voltage to the DC link, wherein the higher voltage is greater than the voltage of the second ESD and causes the switch to decouple the second ESD from the DC link.

International Classification:

G06F 7/00

US Classification:

701 22

Abstract:

A vehicular energy management system (EMS) determines a net total power from a traction drive load, an auxiliary device load, and a regenerative power. If the net total power is a net supply power, the EMS causes regenerative power to be provided to a power source and energy source in a controlled manner to initially charge the power source to a desired state-of-charge (SOC) and then subsequently charge the energy source. If the net total power comprises a net power load, the EMS causes power to be drawn from the power source and the energy source, with a split of the power being drawn from the power source and the energy source being based on a magnitude of the net power load. The EMS adjusts/maintains the SOC set-point of the power source and the DC link voltage based on vehicle speed and relative altitude of travel of the vehicle.

International Classification:

H02J 1/00

US Classification:

307 77

Abstract:

A propulsion system includes an electric drive, a first energy storage system electrically coupled to the electric drive through a DC link, and a second energy storage system electrically coupled to the first energy storage system in a series connection. The first energy storage system comprises a high specific-energy storage device; the second energy storage system comprises a high specific-power storage device. The propulsion system also includes a bi-directional boost converter electrically coupled to the first and second energy storage systems such that a terminal of the first energy storage system is electrically coupled to a low voltage side of the bi-directional boost converter and a first terminal of the second energy storage system is coupled to a high voltage side of the bi-directional boost converter. The series connection bypasses the bi-directional boost converter.

Abstract:

A system includes a control unit having one or more processors and a communication interface. The communication interface is configured to communicate with one or more charging stations that are electrically coupled to receive electrical power from a power distribution grid and that are configured to selectively charge one or more energy storage devices connected to the charging stations. The one or more processors are configured to generate first control signals for communication by the communication interface to the one or more charging stations to control transfer of reactive and/or active power from the charging stations to the power distribution grid. The control signals are generated based at least in part on a load cycle profile of one or more electric machines electrically coupled to the power distribution grid.
