Automated system for managing and transferring energy from electric vehicles, with selectable voltage level outputs, to electrical infrastructures.

Description

1 / 2 Automated system for managing and transferring energy from electric vehicles, with selectable voltage level outputs, to electrical infrastructures.

[001] The energy from electric vehicle batteries can be injected into the electrical grid, enabling bidirectional power flow and mobile storage. The V2X (vehicle to X) concept encompasses all these applications. Classifications vary accordingly: V2G (vehicle to grid) refers to charging or discharging on the electrical grid, V2B (vehicle to build) to discharging in buildings or condominiums, and V2H (vehicle to house) to injection into residences. V2L (vehicle to load) serves specific loads, such as in campsites. In Brazil, ANEEL Normative Resolution No. 1000 prohibits V2G, but allows V2H and V2B restricted to the same consumer unit.

[002] In the field of technology, the present invention adapts and improves a V2H to be used automatically or manually, which was not originally possible, in the transfer of energy that allows electric vehicles to safely and supervisedly supply energy to external devices or systems, where it manages among the available sources, always selecting the one that offers energy quality within the parameters and protects against: islanding; voltage surges; short circuits; both the electric vehicle and the utility grid, as well as the delivery of energy to the load. Meeting current technical standards and offering simple, intuitive operation and integrability with domestic, commercial and industrial electrical infrastructures, it can be implemented in any electric vehicle, from small vehicles to buses and trucks.

[003] In FIGURE 1 we can identify in (1) the electric vehicle, which will function as a mobile energy platform. In (2) we have the utility grid or another energy source such as a diesel / gasoline / gas generator with or without grid generation. In (3) the house is identified, in this case the system load. The POWERBOXSISTEMAS is identified in the callout (4), where the electrical connections from (1) and (2) arrive and go to (3). The system (4) installed in the residence will supervise and act, when necessary (automatic mode) or on user demand (manual mode), between the energy sources to supply the residence.

[004] In Figure 2A we can identify the elements external to the POWERBOXSISTEMAS, where the installer will connect the equipment and the user will have access to the equipment interface. Thus, in this figure we can identify: (7) Indicator light for supply via utility company; (8) Indicator light for supply via mobile energy platform (electric vehicle); (9) Indicator light for supply to the load (residential / commercial / industrial); (5) Numerical voltage indicator; (6) Currents consumed by the load; (1) refers to the equipment box; (4) the connectors for the cables from the utility company; (3) the connectors for the cables for integration with the electrical installation of the load (residential / commercial / industrial); (2) the connectors for the cables for integration with the mobile energy platform (e.g., electric vehicle).

[005] In Figure 2B, the internal view of the equipment shows: (10) the surge, overcurrent and short-circuit protection unit; (11) the connectors for the power utility cables; (12) the connectors for the cables for integration with the electrical installation of the load (residential / commercial / industrial); (13) the microprocessor-based load transfer unit; (14) the cables, sized according to current standards, that connect (11) to (14); (15) the cables, sized according to current standards, that connect (12) to (14); (16) the cable connectors for integration with the mobile energy platform (electric vehicle for example); (17) is the box that houses the equipment, and may be made of some polymeric compound or metal to contain the electrified elements of the POWERBOXSISTEMAS from direct contact of the energized parts with the customer, in accordance with current technical standards;(18) the cables, sized according to current standards, that connect (16) to (14) and; (19) the internal view of the front cover of the POWERBOXSISTEMAS, where the human-machine interface of the described equipment is located. The innovation of this POWERBOXSISTEMAS can be identified in the introduction of an isolated type transformer (20), whose primary is connected directly to the vehicle's power output, after the protections, and the secondary is connected to (13) the microprocessor-controlled load transfer unit, thus providing single-phase voltages at 110V or 220V, or 220V two-phase, as determined by the user.
