Abstract
Description
[Technical field]
[0001] This technology belongs to the field of electric vehicles that run on electricity generated by wind power.
[0002] EVs can be broadly categorized into four types depending on the drive system. A) BEVs are electric vehicles that run on battery power alone to drive the motor. B) HEVs are electric vehicles that run on both an engine and a motor. C) PHEVs are plug-in hybrid electric vehicles that can be charged at home or at a charging station. D) FCEVs are fuel cell electric vehicles that generate electricity using hydrogen and oxygen and run on a motor. [Prior art documents]
[0003] There is no prior art available on this proposed wind generation WGEV bus. Summary of the Invention The problem that the invention is trying to solve
[0004] The objectives of this proposal are: 1. To increase the operating distance of EV buses. 2. To reduce the operating and running costs of buses. We aim to reduce the operating and running costs to zero. 3. To achieve zero CO2 emissions when the bus is operating. Means to solve the objectives
[0005] The issues are resolved by equipping the bus with a wind turbine and using the generated electricity to operate the EV bus. Regarding issue 1, increasing the driving distance of the bus, the WGEV bus of this invention can operate for a long distance without running out of power when driving because the rated power output of the wind turbine equipped on the bus and the battery can replenish power when the generated power is insufficient. Regarding issue 2, reducing the operating costs, the wind generated power and the stored power in the battery, inverter devices, converter devices, and control devices will all function perfectly to operate and drive properly, reducing the operating costs. Issue 3, achieving zero CO2 exhaust gas emissions, will be achieved by operating on 100% electricity. Effects of the idea
[0006] The effect of the idea is that the wind-generated electricity from a wind energy vertical axis wind turbine generator drives the bus motor to operate the bus. In addition, the surplus generated electricity is charged into the battery during operation, eliminating the need to charge the battery. Since all operation of this WGEV bus is performed using the mechanisms installed in the bus itself, the cost of operation is reduced. Furthermore, since it is operated using the EV mechanism, no CO2 exhaust gas is emitted. [Brief description of the drawings]

[0008] The WGEV in this proposal is an abbreviation for Wind Generation Electric vehicle. The EV bus in this project will be referred to as the WGEV bus. Energy management for EV bus operation involves various factors such as power consumption and remaining battery charge. It is believed that the use of wind-generated power is an essential condition for the WGEV bus system to overcome these challenges and operate. The current situation is that the equipment is not used as expected due to a lack of power supply infrastructure for EV vehicle operation, and the charging time for the battery can be long depending on the battery's power capacity, making power energy management time-consuming. It is necessary to promote EV formation, design a system for managing power usage from generation to storage and charging, and carry out a wide-area infrastructure implementation project. Considering the state of energy supply infrastructure, the use of wind-generated power by installing a wind turbine is the optimal solution for EV bus operation that supports medium- to long-distance operation. In order to operate a vehicle as an EV, it is necessary to install various EV-related devices such as inverters, converters, control system devices, etc. and manage and operate them safely and accurately using control technology. Looking to the future, there will be a need for wide-area wireless power supply services and EV operation and energy management.
[0009] For operational driving of WGEV buses, they are equipped with inverters, converters, and control equipment that are energy management devices based on EV transformation. They are equipped with power generation equipment and operate with EV transformation in operation. WGEV buses equipped with vertical axis wind turbine generators and operated rationally achieve the following: 1. Lower business operating costs. 2. No CO2 exhaust gas emissions. 3. Realize the creation of profits through the rational operation of WGEV bus vehicles.
[0010] The braking mechanism of the WGEV bus is a regenerative brake system, and when the WGEV bus brakes, the regenerative brake and friction brake control the vehicle's movement. When the bus decelerates while traveling, the motor generates electricity and charges the battery with the surplus electricity.
[0011] As the bus is equipped with a generator, it is also being considered for the production of WGEV buses to equip the battery with a range extender function to charge it. As a WGEV bus that runs on renewable energy, it is a bus vehicle that takes into consideration both the environment and business operations.
[0012] The function of the controller device in a WGEV bus vehicle is to convert the form of power when it is sent from the battery to the motor. The battery is DC power and the voltage output is also fixed, the converter operates the voltage adjustment function, and the inverter adjusts the power and controls the vehicle's speed adjustment function to run the vehicle. The inverter converts the power from AC to DC and adjusts the current, passes DC current to charge the battery while driving, passes AC current to the driving motor, and the converter adjusts the voltage, and adjusts the power and speed of the bus according to the driver's instructions via the control device to run the vehicle. With these device operations, the WGEV bus is operated and driven. [Explanation of symbols]
