South China's first megawatt-class EV charging station opens in Shenzhen's Longhua

Overview

On August 28, 2026, South China's first megawatt-class electric vehicle charging station, the Longyou Flash-Charging Flagship Demonstration Station, was completed near Meilin Checkpoint in Shenzhen's Longhua District. It was jointly built by Longhua Investment Holding Group, a district-owned enterprise, and BYD, the Shenzhen-based automaker. The station is a flagship project of Shenzhen's "Supercharging City 2.0" initiative and marked the completion of BYD's 10,000th flash-charging station in China.

Background

Shenzhen electrified its public transport early and is regarded as one of China's leading cities in EV adoption and charging infrastructure. The city has set out to become a "Supercharging City" and has been expanding high-power charging. BYD announced its new flash-charging network on March 5, 2026. According to CarNewsChina, it reached 10,000 stations in less than six months, an average of about 55 stations a day. By August 28, the network had delivered about 210 million kWh in total. High-power charging shortens charging times but can place heavy loads on local grids, so integrating it with energy storage and grid management has become a key issue for the industry. The Longhua station was designed as a demonstration of exactly this kind of integration.

Key Points

Item	Details
Equipment	10 flash-charging piles (20 connectors) and 15 supercharging piles (30 connectors)
Peak output	Fully liquid-cooled system, up to 1,500 kW through a single connector
Charging time	For compatible vehicles with BYD's second-generation Blade Battery, 10% to 70% in about five minutes and to 97% in about nine minutes (according to BYD)
Grid support	An integrated energy-storage system stores power at off-peak times and discharges it at peak times

• In 2026, Longhua was selected for the National Energy Administration's first group of pilot projects for a new-type power system and is developing a virtual power plant platform. Longhua Investment Holding Group operates new energy projects in the district, including 5.56 MWp of solar capacity, 7.68 MWh of energy storage and nine charging stations.
• According to CarNewsChina, BYD's flash-charging network covers 325 cities in mainland China and has more than 1.83 million registered users, nearly one-third of whom drive other brands.
• BYD aims to build 20,000 stations in China by the end of 2026 and plans 6,000 stations overseas, including 3,000 in Europe.

Implications for Japan-Shenzhen Exchange

A peak output of 1,500 kW per connector is far above the level of public fast chargers commonly found in Japan, and the technology is likely to draw interest in Japan, where charging time is often cited as an obstacle to EV adoption. However, this performance depends on compatible vehicles and batteries, and no announcement has been made on whether a similar service could be offered under Japan's charging standards and grid conditions. Meanwhile, the combination of storage and charging to reduce grid strain, and the model of a district-owned company partnering with a private firm, may serve as reference cases for Japanese local governments and energy companies. Developments in high-power charging in Shenzhen are also a topic of interest for Japanese makers of battery materials, power semiconductors and electrical equipment. In addition, the fact that nearly one-third of the network's users drive other brands suggests that charging infrastructure is shifting from a service tied to a single automaker toward a more open public service, a trend that may inform discussions on charging networks in Japan.

Outlook

BYD is targeting 20,000 domestic stations by year-end, but reports note that meeting the goal would require about 80 new stations a day over the remaining period. Apart from Europe, the specific regions and schedule for overseas construction have not been disclosed, and no plan for Japan has been announced.

From the Association

The Association will continue to follow developments in new energy fields such as EVs and charging infrastructure in Shenzhen. We will keep working to provide opportunities for companies and organizations from Japan and Shenzhen to exchange information in these areas.
