Intelligent charging is a blue ocean in the development of new energy automobile industry

"From the perspective of the new energy vehicle market, currently 55% of the market is pure electric passenger cars." Ouyang Minggao, academician of the Chinese Academy of Sciences and executive vice chairman of China Electric Vehicles 100, said that with the users of pure electric passenger cars As the demand for cruising range continues to increase, the requirements for high specific energy lithium-ion battery technology and the fitting of charging equipment are gradually increasing. Under this background, intelligent charging will open up another broad space for energy and intelligence. The future will be new energy automotive products with “electrical vehicle + intelligent driving + charging intelligence”, in which charging intelligence is new. A blue ocean of energy automotive industry development.

for the long-term development of power batteries.

In addition, the high specific energy single cell battery is inseparable from thermal runaway prevention and control technology, and it is very difficult to completely prevent thermal runaway, and it is necessary to prevent thermal runaway from the system perspective. This is also true for high specific energy lithium-ion batteries. At the same time, it needs to be emphasized that for the development of high specific energy lithium-ion battery technology, safety is always the first.

How is the current charging equipment configuration? What is the future development prospect of charging?

Ouyang Minggao: At present, the rate of privately-owned charging stations is increasing, and the goal is “one vehicle, one vehicle”. This is very important and should be dominated by vehicle manufacturers. In addition, the nation's public slow charge charging point utilization rate is less than 10%. In the future, the charging of pure electric passenger cars will be a combination of daily slow charging and common fast charging for private AC charging stations.

The private charging piles strive to become 1:1 for supporting and become the charging subject. Before 2020, from the fast charge of less than 60 kilowatts to the fast charge of less than 150 kilowatts, it is recommended to promote the use of self-contained piles while studying various types of charging technologies represented by high-power fast charge. From 2020 to 2025, passenger vehicles will use the public fast-charged power station to supplement the power station. It is recommended to demonstrate a new generation of charging technology and to demonstrate the application of V2G on a large scale. All of them will be applied after 2025.

We must look to the future for the construction of charging infrastructure, and we must not “turn the cake back and forth”. From the perspective of the next 5 to 10 years, the price of photovoltaic power generation in China is expected to be lower than the price of coal power, and distributed renewable energy will become an advantageous energy source. Therefore, the vision for the future development of charging will be the interaction between cars and electricity, and the use of distributed renewable energy and electric vehicle microgrids will help to balance the fast charging load.

In this context, the future-oriented electric vehicle will be a new energy intelligent electric vehicle, that is, "electric vehicle + intelligent driving + charging intelligent" products. At present, there is more talk about driving intelligence and it is relatively hot, and it is almost already the Red Sea market. However, smart charging is still a blue ocean, which will trigger an energy revolution and open up another space for energy intelligence

It should be noted that after the fast charge rate is increased, the peak value of the fast charge power of the electric vehicle is very large, and the renewable energy source is also an intermittent peak. How to coordinate and interact with the

two peaks and achieve a stable and stable power grid must be studied and implemented as soon as possible. The problem.

Next, how can the new energy automotive industry achieve high quality development
