In a recent test of V2G (vehicle-to-grid) technology in Shenzhen, the charging station located in the parking lot of Maluan Mountain Country Park in Pingshan District was recognized as a demonstration station.

V2G technology facilitates the transfer of unused power from electric vehicles (EVs) to the grid. Also known as vehicle-grid integration (VGI), this technology can strengthen the energy grid during peak hours and serve as an alternative power source when weather-dependent renewable energy sources are unavailable. In this way, EVs function as mobile energy storage devices, helping to meet peak load demands.

After upgrading the software of the charging piles in the parking lot of the Maluan Mountain Country Park, the station enables not only ordinary passenger EVs to send excess electricity to the grid, but also pure electric heavy-duty dump trucks. Each of these trucks can continuously discharge up to 300 kWh, equivalent to the daily electricity consumption of more than 30 households or the charging needs of 15,000 mobile phones. EV owners can earn incentives of up to 500 yuan per day for doing so.

Also in Pingshan, Yudian Technologies' supercharging station features a roof covered with perovskite modules, achieving a photoelectric conversion efficiency of 22% — 30% higher than traditional crystalline silicon — significantly enhancing power generation stability in low-light environments.

Its mobile energy storage batteries extend the cycle life of charging and discharging, adapting to photovoltaic fluctuations and achieving 24-hour stable power supply.

Its 600 kW liquid cooling supercharging piles support vehicles to gain a 400-kilometer range with just 10 minutes of charging, specifically designed for taxis, logistics vehicles, and passenger cars.

Shenzhen has become the first city in China where the number of ultra-fast charging stations and plugs has surpassed that of gas stations and fueling nozzles. The city has established a "1-kilometer charging circle" in urban areas, making charging highly convenient.

Pingshan constructed 52 supercharging stations and six integrated stations for photovoltaic energy storage, ultra-fast charging, and V2G interaction in 2024.
