yangzi evening news reported on september 26 (correspondent wang songzhu, reporter gao feng) recently, suqian’s first “optical storage, super charging and discharging” integrated demonstration station was completed and put into operation. it will upgrade the city’s charging service network and further improve charging convenience. positive promotion effect.
the demonstration station is located on the south side of the intersection of weishanhu road and pingan avenue in suqian city. it is jointly constructed by state grid suqian power supply company and state grid jiangsu electric vehicle company. the station is equipped with two 480-kilowatt liquid-cooled supercharging piles, 14 160-kilowatt dc fast charging piles and two 60-kilowatt v2g charging and discharging piles, which can quickly charge 34 new energy vehicles at the same time. at the same time, a 131.4-kilowatt carport rooftop photovoltaic and a 232-kilowatt-hour energy storage system are built.
based on the integrated technology of "photovoltaic storage, super charging and discharging", the site is equipped with a vehicle-network interactive system that aggregates and optimizes load resources such as photovoltaic, energy storage, charging, and discharging in the site to achieve platform-based management. according to real-time weather, electricity prices, new energy vehicles charging status and other information are used to intelligently dispatch photovoltaic, energy storage and vehicle charging and discharging in an orderly manner to form a local microgrid.
during the day, the electric energy generated by photovoltaics will be given priority to charge vehicles, and the remaining electric energy will be stored in the energy storage system and discharged during peak charging periods to help support the electric load. through advanced sponge power technology, the system will prioritize the use of charging piles and energy storage systems to consume the electric energy generated by photovoltaics, and through reasonable charging and discharging algorithms, achieve a photovoltaic consumption rate of 100%, which is equivalent to saving approximately 39 tons of standard coal per year. .
zhu hongji, general and marketing director of the suqian branch of state grid jiangsu electric vehicle service co., ltd., introduced that the maximum output power of the liquid-cooled supercharging pile in the station is 480 kilowatts, which can achieve a charging range of 200 kilometers in 5 minutes at the fastest. it adopts flexible power distribution technology and is suitable for it is compatible with different models on the market, and has a light cord and low noise, allowing car owners to charge and use it with confidence, and easily enjoy the ultra-fast charging experience of "a cup of coffee and a full charge".
based on v2g two-way charging and discharging technology, electric vehicles have also become a mobile "power bank" to realize the recycling of green energy. according to calculations, two 60-kilowatt v2g charging piles can reversely discharge 240 kilowatt-hours of electricity to the power grid for 2 hours, which can meet the electricity needs of 30 households for a day.
in addition, in order to provide car owners with a more convenient and comfortable charging service experience, a charging service station has been built in the station. the station is equipped with air conditioning, tables and chairs, water dispensers, tvs, mobile phone charging, toilets and other service facilities to facilitate new energy car owners while charging. taking a break during this period also provides a warm harbor for new business types and new employment groups.
