Basic knowledge of purchasing new energy vehicles

New energy vehicles include four major types: hybrid electric vehicles, pure electric vehicles, battery electric vehicles fuel-powered and other new energy sources (such as supercapacitors, flywheels and other high-efficiency energy storage devices) automobiles, etc. The latter two vehicles as well as solar vehicles are currently very rare on the market, so common new energy vehicles refer to hybrid vehicles and pure electric vehicles.

Among them, hybrid models are divided into plug-in hybrid models and pure electric hybrid models, but both have motor + motor + battery combination. They can save fuel or improve performance using their respective power. -efficiency ranges. It existsCurrently in the market are mature brands that sell hybrid vehicles, such as Toyota, Honda, BYD, etc. However, at this stage, independent brands like Geely, Great Wall and Chery also have their own hybrid models. , compared to fuel, vehicles of the same level can save about 50% fuel for the same mileage.

There will be more brands and choices in the pure electric vehicle segment, and there are many emerging brands. Currently, pure electric vehicle brands are divided into the following categories. The first category includes domestic and foreign traditional automobile manufacturers, such as BBA, Volkswagen, Toyota and Honda, as well as domestic manufacturers BYD, Great Wall, Geely, etc., which have launched at least 1-3 pure electric models, including high-end models, mid-range and low-end models. BYD is currently the manufacturertraditional automotive company offering the widest range of new energy products. BYD released its production and sales report for June 2022. The company sold 134,036 new energy vehicles in June; its cumulative sales this year were 641,350 vehicles, a year-on-year increase of 314.90%.

The other category is new car manufacturing forces, similar to America's Tesla, China's NIO, Xpeng and other car companies. Their common characteristics are: they have been established for a short period of time and have unique brand concepts or business models. Tesla achieved 321,000 sales in China last year, and China's major new car manufacturing forces, such as Xiaopeng, currently have it. almost 10 sales. Annual sales volume of 10,000 units. Production and sales of domestic automakers emrgents increased significantly in the first half. From January to June 2022, NIO delivered 50,827 new cars, a year-on-year increase of 21.1%. A total of 217,897 NIO vehicles have been delivered. From January to June this year, Xpeng Motors delivered a total of 68,983 units, representing 2.2 times the cumulative delivery volume during the same period last year. Since its delivery, the cumulative delivery volume of Lideal ONE has reached 184,491 units.

Can the 2017 Dongfeng Honda Jade be converted into a sleeper truck and equipped with solar panels?

Do you all have a question from the pure electric? model If charging is slow, there may be no charging stations. Why not develop solar charging to recharge cars? You can then charge it on the go and no longer have to worry about range anxiety. Or maybe someone thought that a single solar panelre wasn't enough to power the vehicle, so how about adding a few more?

Recently, foreign media exposed a set of composite images of solar panel charging based on the modified Tesla Model 3 model. In the photo, not only is a solar panel installed on the roof of the car, and a piece is also installed on the hood, possibly to increase greater charging power.

At the same time, the appearance of the vehicle has also been changed, with front and rear bumpers made of raw steel tubes, roof racks, off-road tires and paint matte black bodywork, making it ready to go. In preparation for a long trip, the carrier is fully stocked with supplies such as buckets and spare tires.

But do you think you can drive this purely electric car for long distances without any qualms? This is notIf so, it’s just wishful thinking on the part of the designer. According to current solar technology, even if the car is equipped with two solar panels, it cannot achieve the purpose of charging the vehicle on the go, at most it can only serve as an auxiliary power supply for the car's entertainment system. vehicle.

Of course the designer is aware of this problem, that's why he also stated that a diesel generator is equipped in the trunk of the vehicle and the bucket on the roof does not contain any drinking water but diesel. The vehicle is powered off, it is charged via this generator Yes, it is similar to Honda's i-VTEC hybrid technology.

In fact, Tesla CEO Musk also said that he would consider installing a solar roof for his models, and that it would be a deployable solar panel installed on the roof . The solar panel would be used during charging. necessary. When unfolded, the size is equivalent to a plaand parking. According to calculations by Tesla engineers, the electrical energy thus converted can provide the vehicle with a range of 30 to 50 kilometers.

With such a huge effort to add 50 kilometers, this project will naturally be abandoned. In addition, the solar roof and the installation of additional solar panels will bring hidden dangers to the safety performance of the vehicle. the vehicle is involved in an accident, it can be easily broken when used, so this design has not yet passed the safety regulations in the United States.

But despite this, no one can say how technology will evolve in the future with such rapid development. Maybe in the early years, no one would have thought of driving an electric car on the streets like today. ago The idea of ​​using solar energy could actually come to fruition in the future. But for now, let this design exist in renderings for everyone to enjoy.

What types of new energy vehicles are there?

No. According to the Pacific Automotive Network's query, the 2017 Dongfeng Honda Jade model cannot be converted into a sleeper truck or installed with solar panels. The interior height of the car is not good, and the space in the back row and trunk is not good. big. There is a height difference of 8 cm between the compartments. Therefore, the Dongfeng Honda Jade 2017 model cannot be converted into a sleeper truck and installed with solar panels.

It is divided into three types: hybrid electric vehicles (HEV), pure electric vehicles (BEV, including solar vehicles) and fuel cell electric vehicles (FCEV).

1. The vehiclesCompound electric vehicles (also called hybrid electric vehicles) refer to vehicles equipped with more than two energy sources, including motor drives, and comply with the For automobiles subject to traffic and road safety regulations, there are many on-board energy sources: batteries, fuel cells, solar cells and generator sets for internal combustion locomotives. Currently, hybrid electric vehicles generally refer to electric vehicles equipped with internal combustion locomotive generators. and batteries.

2. Pure electric vehicles

Pure electric vehicles refer to vehicles powered by on-board energy and using motors to drive the wheels, and complying with road traffic requirements and safety regulations. As its impact on the environment is less than that of traditional cars, its prospectsves are largely optimistic, but the current technology is not yet mature.

Battery electric vehicle (BEV), which is a car powered entirely by rechargeable batteries (such as lead-acid batteries, nickel-cadmium batteries, nickel-metal hydride batteries, or lithium-ion batteries ion). Although it has a long history of 134 years, it is limited to certain specific application ranges and the market is small.

3. Fuel Cell Electric Vehicles

Fuel cell electric vehicles use fuels such as hydrogen and oxygen in the air to generate electrical energy through electrochemical reactions in a fuel cell under the action of a catalyst and serve as the main source of energy for driving cars.
