Description:FIELD OF THE INVENTION

[0001] The present invention relates to a hybrid electric vehicle charging system that is capable of charging the hybrid electric vehicle by utilizing the energy from the renewable sources while maintaining the sustainable and eco- friendly energy supply.

BACKGROUND OF THE INVENTION

[0002] The transportation sector is one of the largest contributors to greenhouse gas (GHG) emissions, primarily due to the widespread use of fossil fuel-powered vehicles. In response to growing environmental concerns, the automotive industry has been transitioning towards cleaner and more sustainable alternatives, such as electric vehicles (EVs) and hybrid vehicles. A hybrid electric vehicle (HEV) combines a traditional internal combustion engine with an electric motor and battery. This design allows the vehicle to switch between or simultaneously use both power sources, enhancing fuel efficiency and reducing emissions. HEVs operate in electric mode during low-speed driving and switch to the combustion engine for higher speeds or longer distances. The electric motor assists during acceleration and recovers energy during braking through regenerative braking. Hybrid vehicles are a practical solution for reducing reliance on fossil fuels while maintaining the convenience of conventional cars. They serve as a bridge toward fully electric transportation.

[0003] Traditionally, hybrid electric vehicles (HEVs) do not require external charging, as their batteries are recharged through regenerative braking and the internal combustion engine. This convenience reduces the need for charging stations but limits electric-only driving range. However, this approach has drawbacks: the reliance on the engine for recharging can lead to higher fuel consumption and emissions compared to plug-in hybrids or fully electric vehicles. Additionally, the battery capacity in traditional HEVs is smaller, restricting their electric-only operation. This limits environmental benefits and energy efficiency. As technology advances, plug-in hybrids with external charging are becoming more popular, offering longer electric ranges and better emissions reduction.

[0004] EP1883552B1 This invention relates to plug-in hybrid propulsion systems where the energy storage element of the hybrid drive train may be charged with externally supplied electricity as well as energy from the engine or regenerative braking. The invention is a plug-in hybrid system with a fast energy storage and delivery system. In a preferred embodiment the invention comprises a fuel powered engine, a battery, a fast energy storage system, power converters, controllers, drive motors, an electrical distribution system, and a drive train. Additionally, the invention relates to plug-in hybrids that provide services to the electrical utility when the vehicle is connected to the utility grid.

[0005] KR101853803B1 The independent power source for each vehicle can be fused or separated and supplied to the battery. The power can be supplied to the in-wheel motor without using a separate power transmission device (e.g., a transmission, a drive motor) The present invention relates to an extended travel type electric vehicle system that maximizes drive efficiency by directly applying a hybrid electric energy source to a hybrid electric energy source. Energy storage means for storing and converting energy generated through the composite energy source; And an energy storage unit that stores energy and converted power, generates power using the stored energy, and directly applies the converted power or the generated power to the in-wheel motor to minimize power transmission loss And a power train system for realizing a mileage-extended electric vehicle system.

[0006] Conventionally, many systems have been developed to charge the electric vehicle device but these devices combine both an internal combustion engine and an electric motor, leading to increased complexity in design and higher maintenance costs. Similarly, the hybrid-flex vehicles often rely on biofuels like ethanol, which might not be readily available or economically viable in some regions.

[0007] In order to overcome the aforementioned drawbacks, there exists a need in the art to develop a system that is capable of leveraging natural resources like sunlight and wind that ensures a more sustainable and eco-friendly energy supply. Additionally, these systems are chargeable while the vehicle is stationary or in motion night increasing driving range and reducing the need for frequent charging stops.

[0025] The plurality of flexible solar photovoltaic (PV) panels 102 operate by utilizing photovoltaic cells, made of silicon semiconductor materials, which absorb sunlight and generate direct current (DC) electrical energy through the photovoltaic effect. The flexible nature of the panels 102 allows them to bend and adapt to complex surfaces without compromising their structural integrity or efficiency. As sunlight strikes the PV cells, photons excite electrons within the semiconductor material, creating electron-hole pairs that generate a flow of electrical current. This electrical energy then harnessed directly to power vehicle systems, stored in batteries, or fed into the vehicle’s electrical network. By conforming to the vehicle’s exterior, these panels 102 increase the effective sunlight-absorbing surface area, thereby optimizing the amount of solar energy captured and enhancing overall energy generation efficiency.

[0026] A plurality of vertical wind turbine 103 encased in a protective cage, integrated onto the vehicle’s structure 101 that is configured to generate electrical energy from wind during motion or when stationary. The protective cage is constructed from a lightweight, durable mesh, reducing drag while ensuring turbine 103 safety and efficiency. The vertical-axis wind turbine 103 includes aerodynamic blades optimized for low wind speeds and variable wind directions.

[0027] The plurality of vertical-axis wind turbines 103, operate efficiently at low wind speeds and from wind coming from any direction, to their vertical-axis configuration. As the vehicle moves or when ambient wind flows around it, air passes through the cage and interacts with the blades, causing them to spin and convert kinetic energy into rotational mechanical energy. This rotation drives an integrated generator, producing electrical power for the vehicle’s storage. The mesh cage minimizes aerodynamic drag, improving overall efficiency while protecting the turbine 103 blades from debris and damage, ensuring safe, continuous energy harvesting regardless of the vehicle’s speed or wind direction.

[0028] To store the electrical energy there is a battery storage system 104 of the vehicle that is electrically connected to the solar PV panels 102 and the vertical wind turbine 103. It includes lithium-ion cells with a capacity sufficient to store energy for extended vehicle operation in low-sunlight or low-wind conditions.

[0029] When the solar panels 102 and wind turbine 103 generate electrical energy, this power is directed through a charge controller that regulates voltage and current to prevent overcharging, then safely charges the lithium-ion battery pack. The lithium-ion cells, chosen for their high energy density and long cycle life, store the electrical energy for later use, ensuring extended vehicle operation even during periods of low sunlight or wind. The system includes inverters and converters to manage the flow of electricity, converting DC from the sources into usable power for the vehicle’s electrical loads or to recharge the batteries. This setup allows continuous energy storage and supply, balancing generation and consumption, and maintaining reliable power availability under varying environmental conditions.

[0031] The Energy Management System (EMS) functions as the central control unit that communicatively interfaces with the solar PV panels 102, vertical wind turbines 103, and battery storage system 104 via digital communication protocols (such as CAN bus or Ethernet). It continuously monitors real-time data on energy generation, storage levels, and vehicle operational conditions. The EMS uses programmed control protocols to prioritize renewable sources: during daylight hours, it maximizes solar energy harvesting by directing generated power primarily to charge the batteries and supply the vehicle’s electrical loads; during motion or in high-wind conditions, it shifts focus to wind turbines 103, harnessing kinetic energy to supplement or replace solar input.

[0032] The EMS manages the distribution of electrical energy by controlling switches, converters, and chargers to optimize efficiency, prevent overcharging, and ensure reliable power supply. It also dynamically adjusts priorities based on environmental factors and energy demands, effectively balancing renewable energy utilization and battery health, thereby maximizing sustainable operation of the vehicle.
