(1) High vehicle efficiency of
Used Car. The vehicle efficiency of
Used Electric Car is much higher than that of
fuel vehicles. The actual efficiency of ordinary fuel vehicles (Tank to Wheel) is only 16%, and the vehicle efficiency reaches 30% after adopting hybrid power. The vehicle efficiency and FCV (fuel cell vehicle) of Used
Electric Car are 81% and 50% respectively. Used Electric Car replace the energy conversion method of "chemical energy-thermal energy-mechanical energy" with "chemical energy-electrical energy-mechanical energy". The conversion efficiency of "electrical energy" as the medium will be as high as 90%, while the conversion method of "thermal energy" as the medium The highest is 40%.
The overall efficiency of Used Car is also higher than that of ordinary fuel vehicles, and improvements in fuel preparation efficiency will further widen the gap with fuel vehicles. The overall efficiency of Used Electric Car is 15% and 14% higher than that of ordinary fuel vehicles respectively. The current efficiency of using fossil fuels to produce electricity and hydrogen is low. However, as the application efficiency of nuclear power, green energy, and hydrogen production technology further improve, the overall efficiency of Used Car is expected to be further improved.
The electrification of automobiles makes vehicles more efficient, brings high energy utilization, and reduces the "money bags" of the common people. As for the high-level arguments such as air pollution, energy crisis, carbon dioxide emissions, etc., they are nothing more than issues of comprehensive energy utilization rate.
(2) The structure is simple, and Used Car will reduce parts by 1/3. The number of parts for an ordinary fuel vehicle is generally considered to be 30,000, of which the engine accounts for about 22%, the drive control accounts for 19%, the body accounts for 15%, the suspension and brakes account for 15%, and lighting and wiring harness account for 15%. 12%, other electronic equipment 10%. Regarding Used Electric Car, 22% of the engine, 7% of the electronic products, and 7% of the drive transmission system are removed. The battery, motor, DC/DC converter, electric brake, etc. will add at most 100-200 parts. Taken together, Used Car will reduce the number of parts by 11,000.
The simplified structure will bring about cost reduction, convenient operation and larger space for interior and exterior beautification. Used Car have significantly reduced parts and components, which means that companies can use less manpower, space, equipment, and management to conduct mass production faster and more efficiently, saving costs. Reducing prices to consumers means lower-priced cars. Moreover, the electric mode brings simpler and more responsive control. The use of wheel hub/wheel motors, high-energy miniaturization of batteries, and lightweight materials provides more room for improvement in vehicle design, which can improve the aesthetics and comfort of the vehicle body.
(3) The requirements for the development of electronics and intelligent networking, as well as the requirements for vehicle performance, have greatly increased the deployment rate of electronic information equipment in the vehicle. The increase in electronic equipment can improve vehicle efficiency and enhance safety, comfort, and convenience. According to estimates, in 1980, the cost of automotive electronic equipment accounted for approximately 3%; in 2000, the proportion of electronic equipment reached 20%; in 2015, the proportion of vehicle electronic equipment costs rose to 30%. According to Used Car, new battery management systems, battery motor control systems, etc. will be added, and the proportion of electronic equipment expenses will exceed 65%.
The intelligent networking of vehicles further increases the amount of information processed. The vehicle electronic system has been extended to the two-dimensional information processing of "people-vehicle-environment". It processes information on road conditions, surrounding pedestrians and vehicles to improve driving safety, and processes information on surrounding charging piles, parking lots, shops, and movie theaters. , improve the convenience of use. This not only requires a huge number of sensors, controllers, chips, etc., but also requires continuous information processing and calculation.
Huge vehicle information processing requires sufficient power support. It can be known from the second law of thermodynamics that the process of processing dissipated information requires energy, and the more chaotic information is converted into more regular usable information, the greater the energy consumption. The increase in the configuration of electronic products and the objective requirements for intelligent networking will force future cars to be equipped with energy storage batteries with sufficient capacity.
(4) Energy structure adjustment, Used Car using "electricity" as the medium realize the output and input of energy without fixed areas and modes. The essence of Used Car is to use electrical energy to drive machinery. When the energy storage system directly communicates chemical energy with the outside through electric current, our energy choices are not limited to certain substances like gasoline. That is, electricity can be produced anywhere and through any channel, and electricity can also be produced in Any central acquisition. This means that energy sources can be adjusted and selected at will according to needs, ultimately optimizing the energy structure. For example, the solar energy stored at home can be used to charge cars or be sold to power companies, and waste oil can be burnt and turned into electricity to drive cars, etc.
