Advantages of pure electric vehicles

(1) Pure electric vehicles have the following advantages: ① Zero emission. Pure electric vehicles use electric energy, and there is no waste gas and no pollution to the environment during driving. ② The energy utilization rate of electric vehicles is higher than that of gasoline vehicles. (3) Because a single electric energy source is used, an engine, a transmission, an oil tank, a cooling and exhaust system are omitted, and the structure is simple. ④ Low noise. ⑤ When the power consumption is low, the car can be charged, which can stabilize the peak-valley difference of the power grid and make full use of the power generation equipment. (2) Pure electric vehicles have the following disadvantages: (1) Short driving range; (2) Using storage battery and motor controller makes the cost higher; (3) Long charging time; (4) There is no authorized service station at present, and the maintenance cost is high; (5) The battery life is short, and it will have to be replaced in a few years.

Problems in the development of pure electric vehicles (1) In terms of technical ability, although domestic automobile manufacturers have expressed their intention to participate in the research and development and production of new energy vehicles, the technical ability of electric vehicles with independent intellectual property rights in China is directly affected due to the limited high-tech content and the number of mass-produced vehicles, and with the intensification of competition in electric vehicles, due to low research and development funds and insufficient innovation motivation;

2) The "power supply" of batteries is the "technical bottleneck" for the development of new energy vehicles. At present, there are two main problems: first, the battery cost is high, the energy density of the battery is low, and the subsequent charging mileage is short; Second, will there be a real battery recycling, leasing and secondary manufacturing industry chain in the electric vehicle market in the future? Third, the battery interface is different, just like the charging ports of different brands of mobile phones are different. The uncertainty of "standard" will have a great impact on the development of electric vehicles.

(3) In terms of energy, the investment of pure electric vehicles is more expensive than that of fuel vehicles, and power plants, transmission and distribution facilities, charging stations and battery factories need to be built to use electricity. (4) In terms of supporting facilities, the important factors for consumers not to choose new energy vehicles are imperfect supporting services, few supporting facilities, backward construction of supporting facilities and inconvenient maintenance. Charging stations are rare and difficult to find in China.
