Description

Technical Field

[0001] This invention is mainly applied to the transportation industry and can be widely used in highways, waterways, aviation and other fields. Background Technology

[0002] People use various means of transportation in their daily work and life. The increasing maturity and progress of battery technology has enabled the widespread application of electric vehicles in production and daily life, such as electric cars, electric two-wheelers, yachts, and the drone industry.

[0003] Compared to gasoline-powered vehicles, electric vehicles have a significantly shorter driving range. While drivers want to reach their destination as quickly as possible while ensuring safety, charging electric vehicles during long journeys can be inconvenient and time-consuming. Building charging systems and charging stations requires substantial investment and does not solve the fundamental problem of charging time wastage. Summary of the Invention

[0004] In view of this, and in order to solve the problems existing in the technical background, an electric vehicle charging system was invented, the details of which are as follows:

[0005] The electric vehicle charging system includes main components such as a battery pack, a motor, a generator, an inverter, and a transformer. The motor is electrically connected to the battery pack via wires to supply power, and the motor and generator are mechanically driven to generate electricity while the vehicle is in motion. The generator output is connected to the inverter and transformer in sequence. The electrical energy is processed and then used to charge the battery pack, enabling the electric vehicle to charge itself while in motion without the need for external charging equipment.

[0006] Furthermore, the system includes two sets of power batteries. Battery pack 1 supplies power to the electric motor, and the electrical energy generated by the generator driven by the electric motor is regulated by a converter and transformer to charge battery pack 2. The two sets of batteries work alternately to achieve continuous power supply and charging during driving. One set of batteries is installed on each of the left and right sides of the car, which facilitates wiring.

[0007] Furthermore, the generator is a wind turbine generator, which is electrically connected to the converter. The auxiliary power generated is fed into the system and, after being processed by the converter and transformer, is used to charge the two battery packs, thereby improving the overall range and charging capability.

[0008] Furthermore, the automatic charging mode and wind power generation during vehicle operation are controlled by a manual switch.

[0009] Furthermore, the main circuit includes dual power supply lines and dual charging lines. When one power supply line and charging line are in operation, the other power supply line and charging line are in a de-energized state.

[0010] Furthermore, in order to make more rational use of the space in various parts of the car, enhance the function of each component, and give full play to its role, the generator can be designed at the wheel hub position.

[0011] Furthermore, transmission wheels are mounted at both ends of the motor rotor shaft, outputting power in two directions to drive the vehicle while simultaneously powering the generator. The motor outputs power to the generator via mechanical transmission, driving the generator to produce electricity.

[0012] The above technical solution has the following beneficial effects:

[0013] This invention combines alternating power supply and charging of two sets of batteries with mechanical transmission power generation and wind power generation, and circuit interlock control to ensure the safe and stable operation of the system. It allows electric vehicles to continuously generate electricity autonomously and replenish the battery during driving, without the need to stop and connect to an external charging station. This completely solves the problems of charging time and insufficient range in daily use or long-distance driving of electric vehicles, reduces infrastructure investment costs, saves people time and money, improves travel efficiency and convenience, and improves battery utilization efficiency.

[0022] Combined with the appendix in the embodiments of the present invention Figure 2 The charging system circuit control scheme in the embodiments of the present invention will be described simply and clearly.

[0023] When switch SA1 is closed, battery pack 1 supplies power to the motor via contactor KM1, controlled by intermediate relay KA1. Relay KA1 also controls contactor KM3 to charge battery pack 2. Once the batteries are fully charged, the charging control indicator HL1 sends a signal, and intermediate relay KA3 disconnects contactor KM3, stopping charging. The two power supply circuits for the motor are interlocked, controlling charging while supplying power, ensuring both power efficiency and circuit safety.

[0024] Using wind turbine G2, contactor KM6 is charged via manual button SB2. Alternatively, contactor KM5 is charged via manual button SB3.
