　　Key technologies such as 6LR61 batteryrestrict the quality of electric vehicles

　　Judging from the current situation of electric vehicles in China, including electric bicycles, the annual sales volume is 30 million units, and the number of vehicles in stock is nearly 150 million units, ranking first in the world. There is a huge gap in the quality and technical level of electric passenger cars currently on the market in China. Sun Muzi, assistant secretary-general of the National Passenger Car Market Information Joint Association, pointed out at the 2013 International Forum on Electric Vehicle Technology Innovation. This forum showcased my country's electric vehicle research and development results, announced the technology development strategy of the electric vehicle industry, and focused on exploring the applications of pure electric vehicles, hybrid vehicles, and fuel cell vehicles.

　　However, many people believe that once low-speed electric vehicles are allowed on major highways, it will cause more serious congestion due to low speeds; low-speed electric vehicles do not undergo comprehensive and in-depth safety crash tests like ordinary cars. If they collide with ordinary cars, the driver will be The safety of the passengers cannot be guaranteed. Therefore, in a certain sense, it has adapted to the current market demand, but it may gradually shrink like the agricultural vehicle market in a few years.

　　At present, the actual cruising range of electric vehicles produced by some enterprises is less than 100 kilometers, and the technical quality and cost gap between lithium 6LR61 batteryand motors are also huge. Some pure electric vehicles are extremely expensive. The A0-class electric sedan is priced at 245,000 yuan and has a short cruising range. For an additional 100 kilometers, the price increases by more than 70,000 yuan, and the weight increases by 200 kilograms. As for the reason why electric passenger cars generally have poor power performance, experts at the meeting believed that the main reason is that there is no gearbox, and good motor characteristics cannot replace the current traditional gearbox.

　　When electric vehicles drive in winter, if they use electricity for heating, especially in the north, north of the Yellow River in China, the electricity consumption will be greater than 10 kilowatts per hour. Generally, the battery storage capacity of small electric vehicles is about 20 degrees Celsius. If electricity is used for heating in winter, the battery life will be very low. The mileage may be reduced by more than 60%, which will greatly reduce the applicability of electric vehicles to a certain extent. Therefore, driving electric vehicles in winter means freezing for most people, and may even affect sales.

　　For consumers who want to buy electric vehicles, the biggest impact on sales is probably that the current domestic charging facilities are too crude and the construction is seriously lagging behind. Extended-range electric vehicles solve the problem of short cruising range and freezing in winter, and the fuel-saving effect can be as high as 40%; for the plug-in hybrid vehicle market, the current power and battery capacity of plug-in motors are on average higher than those of hybrid vehicles. The car is more than twice as big, the motor is powerful, and the braking energy is recovered. During rapid acceleration, the engine and motor work at the same time, resulting in excellent acceleration performance, which solves the problem of preventing passengers from freezing in winter.

　　Judging from the access conditions for new energy vehicles, the relevant person in charge of the National Passenger Car Market Information Joint Conference believes that currently only a very small number of manufacturers truly meet the access conditions. Some companies claim to have mastered battery technology, but they only use the purchased products. 6LR61 batteryform battery packs; some companies say they have mastered electronic control technology, but they do not produce electronic control devices, but purchase them instead of producing key parts. The costs are high, they are not competitive, and they will not really engage in research and development of new energy vehicles. It is necessary to stipulate the minimum types of self-produced key components and improve the performance indicators of new energy vehicles. New policies should be formulated and announced as soon as possible so that the technology of new energy vehicles does not fall behind.

　　Some international automobile manufacturers have also put forward constructive suggestions on how to improve some key technologies of my country's new energy vehicles, combined with the research and development status of their own companies.
