The condition for solving a series of issues and making EVs universal is to achieve high-performance batteries that surpass existing lithium-ion batteries. At present, various countries, research institutions and enterprises are promoting related research and development, and practical application is highly anticipated.

　　Vehicle-mounted secondary battery-related technologies have become popular. The background is that countries all over the world are strengthening carbon dioxide emission regulations. For example, the ZEV (Zero Emission Vehicle) Act in California, the Carbon Dioxide Act in Europe, and China's environmental regulations will all be stricter in the future.

　　As an effective measure to respond to emission regulations, large automakers have high expectations for hybrid electric vehicles (HEV) and pure electric vehicles (EV), and various companies are desperately advancing their development. Large automakers that have not been active in the past will not be able to avoid this problem in the future. Not only that, if this series of environmental laws are not dealt with in a timely manner, it may even be related to the survival of the company.

　　For example, before the US ZEV Act, the target automakers were General Motors (GM), Ford Motor, and Chrysler (now Fiat Chrysler Automobiles) in the US, as well as Toyota, Honda, and Nissan in Japan. But starting in 2018, Volkswagen, BMW, Daimler, Mazda, and Hyundai Group will also become applicable objects. The target companies that will be added later will naturally accelerate the development of electric vehicles in the future.

　　Various electric vehicles

　　Electric vehicles can be divided into several categories according to the technology adopted. Everyone should be familiar with HEV (plug-in hybrid electric vehicle) and EV (pure electric vehicle). More than 15 years have passed since Toyota launched the Prius in 1997, and it has now entered a period of popularization. Toyota is definitely the leader in this field, and Honda is also quite competitive. Among American manufacturers, Ford is vigorously advancing the development of HEV, but it is still far away from Japanese manufacturers. The market penetration rate of HEV is also very high in electric vehicles, and European manufacturers will also actively develop HEV in the future.

　　Let’s review the market trends of EVs. EVs had a low market evaluation before 2012. Nissan’s LEAF (Leaf) and Mitsubishi’s i-MiEV have been struggling to support them. The reason is that it cannot solve the problems of short battery life, long charging time, and high price.

　　The company with even better performance is Tesla Motors, a venture company in the Silicon Valley of the United States. The company’s official EVModelS has an official endurance distance of more than twice that of the Japanese manufacturer’s 483km. The car uses the body design of a sports car, which can provide consumers with the value of sitting once and wanting to sit again. The car has achieved rapid growth, with current sales of 200 vehicles per week and sales of approximately 120 million yuan.

　　Readers may not be familiar with it. In the United States, the popularization of plug-in hybrid electric vehicles (PHEVs) that can be charged at home is GM's Volt. The cumulative sales of Volt have reached 66,000, and the total driving distance of all car owners has exceeded. 600 million miles (about 960 million kilometers). Approximately 23,000 units of the car were sold in 2013 alone, and further growth is expected in 2014.

　　In addition, Japanese manufacturers plan to launch fuel cell vehicles (FCV) in 2015. Honda has been studying the fuel cell as the core of this technology since 1986, and finally saw the hope of mass production after 29 years.
