On November 12, 2023, Shenzhen distributed charge and discharge world's number one brand, outstanding supplier of new charge and discharge solutions, electric vehicle charge and discharge industry disrupter, innovator, standard setter and market leader, Shenzhen Energy efficiency Electrical Technology Co., Ltd. released the world's first C-end "commercial" two-way charging pile D2222kW double gun-wheel charge-discharge two-way charging pile.

A two-way charging pile, as its name implies, can work in both directions, both charging and discharging. When charging, the alternating current of the power grid is converted into the direct current that the electric vehicle power battery or energy storage battery can accept; when discharging, the direct current of the electric vehicle power battery or energy storage battery is converted into the alternating current of the power grid. Two-way charging pile is not only a charging and discharge device, but also an energy router, which can realize energy transmission between vehicle batteries, energy storage batteries, photovoltaic, power grids, electrical equipment and other energy nodes in home and community environment. In the system of two-way interaction between vehicle and network, the two-way charging pile is the core of power regulation and energy flow, which is called energy router. Around "photovoltaic + energy storage battery + electric vehicle", will form trillions of emerging markets, application scenarios and solutions will have endless imagination.

The ultimate scene of the two-way charging pile depends on the support of the government policy, which is that the power grid liberalizes the acquisition of electricity from individual owner electric vehicles, which is the so-called "vehicle-network interaction": the distributed electric vehicle batteries are used as "power sources" to reduce the load of power generation and deployment of the power grid, so as to achieve the sustainable and healthy development of the power grid. Before this final policy is released, D22 will be the world's first two-way charging pile with enlightening and truly commercial value, that is, the value it creates can run well with the business model, and consumers are willing to pay for it.

D22 is a two-way charging pile which can charge two guns in turn.

D22 is a two-way charging pile which can charge two guns alternately. The maximum power of charging is 22kW. The range of charging voltage is 200V-1000V, and the range of constant power voltage is 300V-1000V.

22kW double-gun wheel charging, compared with 22kW single-gun, can save the purchase cost of charging pile, save installation power, save site, and better cope with the internal charging needs of manufacturing enterprises. For example, an electric light truck, 60 kilowatt-hours of electricity, uses D22 to charge two electric light trucks, starting with SOC 20%, and filling a car in two hours. It takes only four hours to fill two cars a day.

The cost of nearly a charging pile has been saved, but what benefits can it bring?

D22 is a two-way charging pile which can discharge alternately with two guns.

D22 is a bi-directional charging post which can discharge alternately with two guns. The maximum power of the discharge is 22kW, and the voltage range of the battery that accepts the discharge is 200V-920V.

What is the electricity consumption model of a typical family of three?

In the morning, during the valley, the husband / wife gets up, cooks breakfast for their children, goes out to work, and takes the children to school on their way. It takes about 1.5 hours, which is equivalent to the loss of electric lamp, and the comprehensive power consumption is about 1.3 kilowatt-hours.

At dusk, at rush hour, the children come home from class, and the adults come home from work and begin to cook dinner. It takes about 2 hours, and the comprehensive electricity is about 2 kilowatt-hours.

At night, usually, after dinner, turn on the electric water heater to bring warm hot water to the family. After the bath, the washing machine takes over the electric baton. The comprehensive electricity consumption is about 3.91 kilowatt-hours.

After the trivial routine, the family spent a wonderful evening in the cool company of the air conditioner. In the valley, the comprehensive electricity consumption is about 11 kilowatt-hours.

Taken together, a family of three consumes about 18.2 kilowatt-hours of electricity a day and 546 kilowatt-hours a month.

* the above power consumption is extracted from large online shopping platforms.

According to the Shenzhen resident electricity Price list, which has been implemented since February 1, 2022, if the family of three chooses to implement the ladder electricity price and calculate the electricity price according to the summer standard, the electricity charge of the first ladder is 172.35 yuan and that of the second ladder is 203.88 yuan, totaling 376.23 yuan.

If this family of three independently chooses to implement the peak-valley electricity price, according to the principle of first time-sharing and then ladder, in this 546 kilowatt-hour, the valley electricity is about 369 kilowatt-hours, and the electricity charge is 94.93 yuan; the peak electricity is about 60 kilowatt-hours, and the electricity tariff is 67.25 yuan; the usual electricity consumption is about 117 kilowatt-hours, and the electricity charge is 77.56 yuan. The second incremental electricity charge is 14.3 yuan, and the comprehensive electricity charge is 254.04 yuan.

Suppose this family of three, after choosing to implement the peak-valley electricity price, buys a two-way charging pile and has a pure electric car at home. We can imagine a scenario: after the daily trip home, the vehicle still has part of the remaining electricity to meet the electricity needs of the family until the valley time comes, and the two-way charging piles automatically fill up the electricity for the vehicle after the arrival of the valley time. then the family saves about 99.39 yuan a month on electricity!

D22 is a two-way charging pile that can charge and / or discharge alternately with two guns.

D22 is a two-way charging pile that can charge and / or discharge alternately with two guns. Taking turns charging and / or taking turns discharging means that the combination can be very flexible. The above-mentioned alternating charging and alternating discharge are two combinations. There is also a combination of A gun charging, B gun discharge, or A gun discharge, B gun charging. There are four combinations in total.

A gun charge, B gun charge.

A gun discharge, B gun discharge.

A gun charges, B gun discharges.

A gun discharges, B gun charges.

D22 can support the access of energy storage battery, which can be connected to any charging gun.

D22 can support the access of energy storage battery, which can be connected to any charging gun. The energy storage battery is an option, and the charging agreement of the energy storage battery conforms to the 27930 national standard.

According to the design logic that the two guns can take turns charging and / or discharging, you will smile when you realize that the D22 can also be connected to the energy storage battery. This will enrich the application scenario, which will be a product definition that will detonate the market.

This product is mainly for industrial and commercial customers. We imagine that electric vehicles used by enterprises and personal electric vehicles working in the park will discharge to the factory during working hours. With this self-sufficient discharge, companies can give car owners a price difference, which is slightly lower than the government's peak-to-valley price difference. The electric vehicles used by enterprises are regularly delivered once or twice a day, how much can they discharge every day without affecting the delivery? Depends on the distance and time of delivery, as well as the battery capacity of the vehicle. For example, enterprises in Dongguan deliver goods to customers in Shenzhen twice a day, with a distance of 120 kilometers, and twice a day is 240 kilometers, which takes six hours. The remaining 18 hours, 3 hours can be charged in the second half of the night, 15 hours can be discharged to the factory. For example, in the Dongguan-Shenzhen delivery scene, two 22kW guns can handle two cars. If the electricity price difference between industry and commerce where the business owner is located is high enough, you can plug another gun into the energy storage battery.

Suppose that business owners buy 30% more charging piles than one-way charging piles, which is a small investment, but it will bring long-term benefits. Cost recovery is much faster than energy storage.
