Driving an electric car, like using a mobile phone, can encounter "battery anxiety" from time to time.But a new technology launched in tianjin is doing just the opposite: instead of charging electric cars, let them charge the electricity grid.

    This technology is a new type of charging pile, not only can charge, but also reverse "receive power", so that your car into a large charging treasure.At peak times, car owners can charge into the grid and earn a premium.The new charging piles are located in the sino-singapore tianjin eco-city, which was jointly built by China and Singapore.

    Earning price differentials may sound good, but how much is it?Tianjin electricity price table shows that industrial electricity peak/peak and trough price difference is generally between 0.5 yuan and 0.7 yuan/degree.In terms of battery capacity of electric cars, tesla's Model 3 rear drive long endurance version is 75 degrees, which is the industry's top level.Ideally, if you drive a Model 3 every day to make money, you could make 38-53 yuan a day.

    However, this is only an ideal state, considering the battery capacity, electricity price changes, actual electricity consumption, a day to earn a dozen pieces of estimation is not bad.And since reverse charging can be inconvenient for cars, the technology seems a bit lame.

    From a personal point of view, reverse charging is a bonus.If the timing is right, you can earn a few drinks.But for countries, it means something completely different.

    We know that the grid doesn't store electricity, it USES as much as it generates, and that's why prices have peaks and troughs.Wind, solar power, such as the unstable current, a lot of time can only be wasted.To solve these problems, energy storage is the key.In march, tesla deployed the world's largest battery system to a small island.But for cities with millions of people, that is obviously impossible.

    Electric cars have become a viable option.Through the interaction of the car network, each car becomes a small mobile battery.If there are hundreds of thousands of electric vehicles in the city, the total is considerable.Nissan worked on a similar project with Britain's national grid in 2016.This technology has important implications for grid regulation and national energy strategies.

    Car owners make small money, the country makes big money.Although the current electric vehicle is not so convenient, but the development of new technology, will let us understand the significance of the development of electric vehicles.
