"Junfeng" also participated: allowing electric vehicles to transmit electricity in reverse
I remembered the demonstration hall of Qingdao Telecom Company in 2017. Chairman Yu Dexiang described to the outside world a scene of electric vehicle charging and discharging in the future, where electric vehicles can be used as energy storage devices to store electricity at night when electricity is abundant; electricity is used during the day During peak hours, it is also the idle time of vehicles, and the storage of vehicles is sent back to the grid through the charging network to supplement social power demand.
"The organic combination of the economy of valley power and the benefit of crest point will surely subvert the business model of the grid system; how to manage multi-point charging and discharging will definitely introduce blockchain technology to manage the transmission network system", this is Jun The opinion of wind company experts.
Whether electric vehicles can become battery energy storage devices, many years later, today, we see hope!
At the conference that opened on September 16, Xin Baoan, chairman of the State Grid, said that V2G technology is widely used, allowing electric vehicles to send electricity back to the grid, which has huge potential for dispatchable energy storage.
State Grid Xin Baoan: Carry out the wide application of V2G technology so that electric vehicles can reverse power to the grid Allow electric vehicles to send electricity back to the grid
Xin Baoan said that the State Grid has built 18 V2G demonstration stations and 600 V2G demonstration stations in 14 provinces, providing 170 million kWh of peak-shaving power for the grid, consuming 2.6 billion kWh of green power, and achieving technology traceability under the blockchain. All parties are working hard to achieve low-voltage electricity for new energy vehicles in residential areas by 2025, and the proportion of new energy electricity charged by the Internet of Vehicles platform will reach 80%.
Experts from Junfeng Company participated in the discussion and believed that to make electric vehicles an energy storage device and safely and economically return electricity to the grid, the core technology is the advancement of battery technology, including the energy density of the battery, the life cycle of repeated charging and discharging, and the battery The management support of the BMS system, the matching of battery life and the value of the return power generation, the gateway and security of the charging network. If these problems cannot be effectively solved, the idea of returning power will be a legend.
To create the future depends on technological progress and rich imagination. We look forward to the early arrival of the era of electric vehicles as energy storage equipment.
