The development of new energy vehicles and renewable energy has become a trend

"We should vigorously promote the development of integrated charging facilities for 'optical storage, charge and discharge' as one of the important means to reduce carbon emissions, and do a good job of standardization."

Recently, the People's Government of Hefei, Anhui Province issued the "Implementation Opinions on Accelerating the Development of New Energy Automobile Industry" to encourage the construction of "optical storage, charging and discharging" (distributed photovoltaic - energy storage system - charge and discharge) multi-functional integrated station. According to relevant statistics, at present, there have been six provinces and cities in the country to explicitly encourage the development of "optical storage, charge and discharge" integrated charging facilities.

The "optical storage, charging and discharge" integrated facility integrates photovoltaic power generation, energy storage, microgrid control, electric vehicle charging, and user rest experience, and combines photovoltaic power generation, intelligent charging pile and power station building to provide users with intelligent, efficient, economical and convenient services. So, what changes will the construction of "optical storage, charging and discharging" multi-functional integrated station bring to the development of the new energy automobile industry? In the future, how should "optical storage, charge and discharge" integrated charging facilities be developed?

Electric vehicles "transform" energy storage system

At present, the layout of charging facilities is difficult to support the development of new energy vehicles, which has become an important factor restricting the development of the new energy vehicle industry. "Difficult to charge" has become a major obstacle for people to buy new energy vehicles.

Many industry insiders agree that "optical storage, charging and discharging" is an important development direction of the energy industry, which is of great significance to crack the bottleneck of the development of the new energy automobile industry.

At present, most charging stations are built separately in the open space, and the construction of photovoltaic panels in the roof of charging stations cannot fully meet the needs of charging stations. Cui Dongshu, secretary general of the National Passenger Car Federation, said in an interview with reporters that encouraging the construction of "optical storage, charging and discharging" multi-functional integrated station is conducive to optimizing the source of electricity for electric vehicle charging.

Cui Dongshu pointed out: "People first use photovoltaic power generation, then use energy storage equipment to effectively store and use these electricity, and realize the effective use of electricity in a small cycle, which can solve the problems of photovoltaic electricity difficult to access the Internet, electricity waste and so on." It's a good boost for energy development."

Research results have shown that through IT technology and policy promotion, the integration of all electric vehicles into an energy storage system can enhance the resilience of the power grid and expand the new energy consumption space. In theory, this is also an idea to vigorously develop the electric vehicle industry.

Wang Binggang, leader of the National new energy vehicle innovation project team, told reporters that the "optical storage, charging and discharging" multi-functional integrated station takes electric vehicles as an energy storage system, and charges them when the grid is low, which can optimize the entire system. "Using electric vehicles as an energy storage system can greatly reduce the grid's investment in energy storage."

Ease the impact of electric vehicle charging on the grid

The reporter learned that the integrated solution of "optical storage, charging and discharging" can solve the problem of limited land resources supporting the power grid, as well as the problem of insufficient distribution capacity of charging stations. By discharging energy storage units, the impact on the power grid can be reduced.

The relevant person in charge of BAIC new energy has said that while the scale of new energy vehicles continues to grow, the fast charging capacity of electric vehicles has increased year by year, "super fast charging" has also been put on the agenda, and "high-power fast charging" has a certain negative impact on the grid. Therefore, the more grid-friendly "optical storage, charge and discharge" integrated station has considerable development prospects.

Cui Dongshu believes that the collaboration between new energy vehicles and renewable energy will bring a wider scope of application to new energy vehicles. "In some areas where power facilities are not perfect, 'optical storage and discharge' can solve the problem of power supply." The efficient collaboration between the new energy automobile industry and renewable energy will promote the further popularization of photovoltaic, the clean and low-carbon transformation of energy and the promotion of new energy vehicles."

How to solve the problem of photovoltaic power generation affected by the weather? "Adjusting charge and discharge is relatively easy to do in the charging process. Charge and discharge can be flexibly adjusted through the charging APP to encourage consumers to charge when the power supply is high, and do not charge when the power supply is low. This helps the safe operation of the grid and maximizes the efficiency of power generation." Cui Dongshu further pointed out.

Standardization of facilities should be kept up

However, the construction of "optical storage, charging and discharging" multi-functional integrated station is not easy.

Wang Binggang believes that the construction cost of "optical storage, charging and discharging" multifunctional integrated station should be reduced, a more efficient and cheaper "optical storage, charging and discharging" system should be established, and a more standard and mass-produced "optical storage, charging and discharging" multifunctional integrated station should be built. "The 'Optical storage, charge and discharge' multifunctional integrated station must also increase its intelligence level to ensure that its energy efficiency is maximized."

"We should vigorously promote the development of integrated charging facilities for 'optical storage, charge and discharge' as one of the important means to reduce carbon emissions, and do a good job of standardization." Wang Binggang further said.

How to develop synergistically between new energy vehicles and charging facilities and promote the construction of multi-functional integrated stations of "optical storage, charging and discharging" through the price system is particularly noteworthy.

In this regard, Cui Dongshu suggested that the construction of the information system should be strengthened, as well as the coordination between electric vehicle charging and the energy system, to mobilize the enthusiasm of consumers for charging, and to ensure the effective allocation of electric energy.
