The overwhelming superiority of new energy vehicles Ⅱ

In order to achieve mass production and reduce costs, some specifications may be changed in order to comply with local regulations and special conditions, otherwise each model is usually a common type. This means that a car must be able to adapt to various local conditions in various countries in the world, such as terrain, road conditions and climate, etc., which are the most basic conditions, in order to meet the convenience of consumers to drive as they wish. Taking the largest market, the United States as an example, it has a vast territory and frequent commercial activities. It is common to travel across states by car. It may pass through various terrains such as plains, deserts and mountains, and experience different climates such as sunshine, heavy rain and snow. Therefore, it must endure from high temperature to low temperature dynamic range which is the most basic requirement. At present, the components of automobiles need to undergo strict temperature tests and have standard verification procedures, which have long been the most frequently discussed basic specifications in the automotive supply chain.

Endurance is another extremely important indicator. You can go straight to your destination without having to find a gas station or a charging station halfway through a refill of fuel or even a full charge. Especially in remote areas, the distribution density of gas stations is sparse, and cars with high endurance are even more important. Due to the pressure of the energy crisis and carbon emission issues, in the past two decades, the world's major automakers have invested a lot of development resources in the internal combustion engine of fuel vehicles, so they have made great progress in fuel saving, which is relatively reflected in the increase of endurance. New energy vehicles need to maintain or even surpass the level of fuel vehicles in terms of endurance, then they have the meaning of generation exchange. The power of the car does not only provide driving, but also needs to meet the power consumption of audio and video, communication, anti-theft, monitoring and air conditioning, and even advanced driver assistance systems. In order to provide more functions, these electronic devices consume more and more power, which will directly affect the performance of battery life. Therefore, the energy supply of new energy vehicles must be stable and sufficient, and have capacity expansion to meet more new application needs in the future, to ensure that the battery life is not sacrificed, and even to retain room for growth.
