Do new energy vehicles need to start batteries?

Pacific car network needs high and low voltage of power battery, so it cannot be used directly. Power supply is needed to start the substation equipment in the car, open the door and start the power battery relay. This power supply is a standard lead-acid power supply. The new energy vehicle can be started when charging, but it can't be driven in gear. An electric car has two batteries, one is the power battery and the other is the starting battery.

A few days ago, seven domestic automakers jointly established the Automotive Power Battery Research Institute with Beijing Nonferrous Metals Research Institute and Tianjin Li Shen Battery Co., Ltd., * * * launched an impact on the core technology of batteries to break the ice. The industry believes that if the core technology of battery can break the ice as expected, new energy vehicles will truly usher in market opportunities-the key technology for the automobile industry to break the ice together-Guojia Automobile Power Battery Research Institute was recently established. Seven vehicle companies, including FAW, Dongfeng, SAIC, Changan, BAIC, GAC and Brilliance, Beijing Nonferrous Metals Research Institute and Tianjin Li Shen Battery Co., Ltd. jointly initiated the establishment of Guojia Automobile Power Battery Research Institute in Beijing. The industry believes that the establishment of the institute is an important attempt by the automobile industry to jointly promote the core technology of new energy vehicles to break the ice.

It is understood that Guojia Automotive Power Battery Research Institute will mainly focus on lithium-ion power batteries, and at the same time carry out research on other types of power batteries such as fuel cells and nickel-hydrogen batteries. In addition to major car companies, Tianjin Li Shen, one of the sponsors, is the representative brand of lithium batteries in China, with the top five market share in the world.

According to Dong Yang, Secretary-General of China Automobile Association, the organization will recruit talents from all over the world, earn income by transferring research results, and improve operational efficiency and achievement transformation efficiency in a market-oriented way. The vision is to establish a world-class research institution for power battery technology. (Reporter Tong Na) Where is the "bottleneck" card of the battery? Our reporter Liu Jin According to the statistics of China Automobile Industry Association, in 20 13 years, China produced 17533 new energy vehicles, with a year-on-year increase of 39.7%. The output of less than 20,000 vehicles is very small compared with the scale of ordinary cars with a production and sales of more than 20 million vehicles in the same period. One of the difficulties in promoting new energy vehicles is the battery problem. Then, why is the battery problem of new energy vehicles not well solved?

The battery with insufficient endurance determines how far the new energy vehicle can run. In recent years, with the frequent introduction of various favorable policies, the new energy automobile industry has made great progress, but the development bottleneck has not been solved due to the limitations of batteries. Consumers are generally worried that the car's endurance is insufficient, the willingness to buy is not high, and the willingness to produce will also decline. Therefore, new energy vehicles have fallen into a vicious circle of marketing difficulties.

A survey conducted by a professional organization in several cities found that most consumers drive less than 50 kilometers a day. At present, the cruising range of new energy vehicles on the market can meet the daily needs of most consumers. The person in charge of a well-known domestic car company also publicly stated that according to the daily use situation, there is no need to worry too much about the battery life.

On the other hand, some professional organizations have calculated that only when the battery life reaches more than 300 kilometers can new energy vehicles be truly commercialized. Therefore, the batteries widely used in the market are far from the requirements of commercialization.
