Embodiment Construction

[0036] Reference below Figure 1 to Figure 1 1 Embodiments of the present invention are described by way of example only.

[0037] figure 1 A photograph of an exemplary EV pickup truck 100 that may incorporate the power hub disclosed herein is shown. EV pickup truck 100 may operate using only electric power, and may, for example, contain a 450V lithium-ion battery pack. Although a pickup truck is shown, it will be appreciated that the power hub may be used in any other type of electric vehicle.

[0038] figure 2 A schematic diagram showing different modes of operation according to which the power hub disclosed herein is configured to operate. As will be described further herein, the power hub may operate in vehicle-to-grid (V2G), grid-to-vehicle (G2V), vehicle-to-home (V2H), and vehicle-to-vehicle (V2V) modes of operation. Such as figure 2 As shown, in the V2G mode of operation, power from electrified vehicles 202 may be delivered to grid 210 . A charged vehicle 202 m...

Abstract

A power-hub for an electric vehicle and operating modes thereof are disclosed herein. The disclosed power-hub is designed to operate in the Vehicle-to Grid (V2G), Grid-to-Vehicle (G2V), Vehicle-to-Home (V2H), and Vehicle-to-Vehicle (V2V) operating modes. When operating in the V2V mode, the power-hub is configured to allow for sending DC power through a conventional AC power port, with all the associated ratings and constraints from the AC design, in order to achieve higher power transfer and efficiency for V2V operation. A digital Hysteretic Current Mode Control (HCMC) scheme is disclosed andthe efficiency and loss distribution of four operating modes are disclosed for the power-hub: 1 ) DC-AC Boundary Conduction Mode (BCM), 2) DC-AC Continuous Conduction Mode (CCM) / BCM hybrid, 3) DC-DC BCM, and 4) DC-DC CCM. A low-frequency commutation scheme is also disclosed that allows for reducing the peak junction temperature.

Description

technical field [0001] The present disclosure relates to a power hub for an electric vehicle, and particularly to a control method and an operation mode of the power hub. Background technique [0002] Range anxiety and slow charging times remain significant barriers to widespread adoption of electric vehicles (EVs), and plug-in electric vehicles (PEVs) in particular. Current EV owners face the possibility of getting stranded with a fully discharged battery en route, or alternatively, if left unattended in a parking lot and left unplugged at a low state of charge (SOC), the EV May be completely discharged. In such cases, existing solutions for EV owners typically require towing the vehicle to the nearest charging station. [0003] Accordingly, additional, alternative, and / or improved power hubs for electric vehicles remain highly desirable. Description of drawings [0004] Other features and advantages of the present disclosure will become apparent from the following det...
