Description

A low-speed solar energy electric vehicle

technical field

The utility model relates to the technical field of electric vehicles, in particular to a low-speed solar energy electric vehicle.

Background technique

Low-speed electric vehicles generally operate at a speed of less than 70 kilometers per hour, and consume less energy than traditional vehicles. The power consumption per 100 kilometers can be controlled below 15kWh, and the cost of electricity per kilometer is extremely low. Low-speed electric vehicles are easy to drive and manipulate, and are suitable for special groups such as retired elderly and housewives; they have a simple structure and are easy to maintain; they do not require high charging infrastructure, and are more convenient to park and charge. Low-speed electric vehicles meet the needs of most low- and middle-income groups, and are ideal miniature means of transportation. The huge upgrade needs of users such as electric bicycles, motorcycles, and low-speed vehicles constitute a huge potential market.

Existing low-speed electric vehicles are powered by batteries. Due to the limited power supply and fast consumption of batteries, current low-speed electric vehicles have shorter travel distances. The current low-speed electric vehicles are generally charged before use and driven by electric energy, but it is inevitable that the electric energy will run out and break down halfway during driving; and driven by electric energy, although there is no environmental pollution, but More power consumption, not energy saving.

Utility model content

The technical problem to be solved by the utility model is to provide a low-speed wind-solar energy electric vehicle capable of being fully environmentally friendly and energy-saving.

The technical scheme that the utility model adopts is:

A low-speed solar energy electric vehicle, including a car body and a chassis, rear wheels, rear wheel axles and rear drive axle assemblies are installed at the rear of the chassis, the rear wheels are connected to the rear wheel axle, the low-speed wind energy electric vehicle The solar silicon crystal panel is installed on the roof of the car, and a DC motor, a solar conversion charging circuit, a battery and an AC charging device are installed in the chassis. The solar silicon crystal panel is connected to the battery through the solar conversion charging circuit and the microcontroller, and the battery is connected to the DC motor; The charging device is connected to the storage battery through the microcontroller; the motor shaft of the DC motor is connected to the rear drive axle assembly, and the rear drive axle assembly is connected to the rear wheel axle; the front end of the chassis is also equipped with a wind generator, and the wind power generator The machine is connected with the storage battery through the wind energy conversion charging circuit, the rectifier and the microcontroller.

Further, the wind power generator is a horizontal axis wind power generator.

Further, the horizontal axis wind power alternator is a transition type synchronous generator.

The beneficial effects of the utility model are:

The solar silicon crystal plate is installed on the roof of the car body, and a DC motor, a solar conversion charging circuit, a battery and an AC charging device are installed in the chassis. The solar silicon crystal plate absorbs solar energy and charges the battery through the solar conversion charging circuit, and the battery is also connected to the AC. Charging device, when the solar energy cannot fully charge the battery, the AC charging device is connected to an external AC power supply to charge the battery. The battery is electrically connected to the DC motor, and the motor shaft of the DC motor is connected to the rear drive axle assembly. The battery provides electric energy to rotate the DC motor and drive the rear drive axle. The assembly rotates the axle of the wheel, and finally drives the electric sightseeing car to travel.

Due to the small size of low-speed wind energy electric vehicles, the space for installing solar panels on the car body is limited, so for most electric vehicles, the energy provided by solar panels is only a supplement. The use of the new model is further equipped with wind power generators. The wind turbine adopts a horizontal axis wind turbine, and the cost is relatively low; it is installed at the front end of the vehicle, and the center of gravity of the whole device is low, so it is not easy to cause the vehicle body to swing when the wind speed is high; no tail fin and yaw system are required to drive the paddles Ye, the design of the wind turbine frame is simple; it solves the problem that when the horizontal axis wind turbine is located on the upper part of the car body, there is a large mast, which causes the overall height of the car body to increase, and the maintenance is inconvenient, especially the problem of visual impact. Due to the small size of the wind turbine, it can be started in the first and second winds, can generate electricity well in the third and fourth winds, and can reach full load in the fifth winds. It is suitable for popularization and use in most parts of the country and has good stability. , the cost is significantly reduced. The utility model can make full use of the potential energy or wind energy when going downhill, and convert it into electric energy when it is downhill, and it can also play the role of braking by slowing down the speed of the vehicle, so that the low-speed wind energy Electric vehicles run more smoothly and are safer. Wind energy is one of the main power sources, and light energy is used as a supplement, which can charge the battery at any time, which solves the problem that the battery is easy to overheat and affect the service life of the battery when the electric vehicle is fast charging. Due to the small body size of small low-speed electric vehicles, they are only used for carrying people or traveling, and the weight of the body is small, so the energy consumption is low. Taking a small low-speed electric vehicle with a power of 1 kilowatt as an example, the energy generated by wind energy can reach 40-60% of the energy required for the operation of the entire system, and the energy absorbed by solar panels can reach 10-20% of the energy required for the operation of the entire system. Completed by charging. It can be seen that the comprehensive utilization of wind energy has a very significant effect on small low-speed electric vehicles, which can greatly reduce the consumption of electric energy and extend its travel. The device can be charged when it is running, and it can also be charged when it is still, and the charging is slow charging, and the charging is very stable. The utility model has a novel structure and can be charged not only by external alternating current but also by solar energy and wind energy, and the utility model intelligently selects AC charging, solar energy, and wind energy charging for the storage battery through a microcontroller, so as to achieve the purpose of fully utilizing solar energy and wind energy.
