New energy vehicle charging "on-demand distribution" Shenzhen sample: 2018 will enter the "big outbreak" first year?
The nationwide construction of charging stations is moving forward rapidly, but challenges such as inefficient layouts and mismatched designs with market needs are becoming increasingly apparent. Yu Dexiang, Chairman of Special Call New Energy Co., Ltd., recently stated that 70% of current charging piles may be phased out in the future. One key reason is the rapid evolution of vehicle charging technology, which will require upgrades to existing infrastructure. This transformation could be as complex as rebuilding entire buildings.
In December 2017, Shenzhen launched its "Technical Requirements for Flexible Charge Reactors for Electric Vehicles," marking China's first local standard for flexible charging technology. The concept of flexible charging allows dynamic allocation of power based on the specific needs of each vehicle, improving efficiency and reducing waste.
On January 7, 2018, Chengdu introduced its smart flexible charging bow, capable of delivering up to 450 kW of power, enabling a bus to charge in just 8 minutes. Liu Yongdong from the China Electricity Council’s Standardization Center noted that as the electric vehicle industry expands, there's a growing demand for centralized, high-power charging solutions.
In 2018, finding a more efficient and reasonable charging solution became a major challenge for local governments. Flexible charging technology offers a promising alternative, addressing concerns about long charging times and varying power requirements.
Shenzhen has taken the lead in implementing this approach. According to the technical requirements, a flexible charging system can dynamically allocate power from multiple charging modules, allowing simultaneous charging of various vehicles. Li Zhigang, an engineer at Aoxun, explained that this system acts like a shared power tank, ensuring each vehicle gets the exact power it needs.
At Aoxun’s Power Building in Shenzhen, reporters saw a large-scale flexible charging reactor that occupies around 20 parking spaces. It can support 16 different power levels simultaneously, significantly increasing equipment utilization. Unlike traditional fixed-power chargers, which either underutilize resources or fail to meet higher power demands, flexible systems adapt to user needs.
Li Zhigang emphasized that future advancements in charging power will not require replacing the entire charger, only the terminal. This makes the system scalable and cost-effective.
With over 70 charging reactors already in operation, Shenzhen continues to refine its model. The best-performing station in Shajing District serves approximately 900 vehicles monthly, operating with a small team of four staff members.
Despite these successes, challenges remain. Yuan Gang, ADT’s deputy general manager, pointed out that current policies focus on the number of charging piles rather than service quality. He believes that shifting the evaluation metric to the number of vehicles served would greatly boost the adoption of new technologies.
As electric vehicle sales surged in 2017—reaching 774,000 units produced and 777,000 sold—charging infrastructure still lags behind. With over 1.5 million electric vehicles on the road, the need for better charging solutions is urgent.
Plans are underway in cities like Nanjing, Guangdong, Zhejiang, and Shanghai to expand charging networks significantly by 2020. However, the challenge lies in planning and allocating space efficiently.
Volkswagen’s CEO highlighted that many existing fast-charging stations have limited power (around 40 kW), leading to long charging times. High-power charging, which aims to reduce charging time to 15 minutes for a 500 km range, is expected to be a key trend in 2018.
Experts suggest that increasing voltage to 1,000V could improve efficiency, but compatibility with existing systems remains important. Liu Yongdong noted that high-power and traditional charging systems will coexist, as different regions and users have varying needs.
Looking ahead, the goal is to make charging as quick and convenient as refueling, turning charging stations into gas station-like hubs. As technology advances, the future of electric vehicles depends on smarter, more flexible charging solutions.
