Charging stations and service stations is similar to a "power up" devices.

Is a highly efficient charger, you can quickly give mobile electric vehicles, electric vehicle charging.
  Have to the Hong electric vehicle charging stations　　The electric car is currently the most widely popular, green travel, transport of energy saving and environmental protection . Electric car charger, a charge often need 7-8 hours, once driving on the way there is no electricity, will allow traffic embarrassing situation. According to the survey of 10 electric vehicle users have at least five owners had suffered electric car "broke down", even if the electric car pedal, but the electric car design and bike do not step up is very natural, and the weight of the electric car is generally about 50 kg, the pedal is very difficult. Electric vehicle fast charging stations as automobile service stations, storage shed next to the street shops, neighborhoods and communities, newsagents, etc. set of lottery points.
With the popularity of the charging station, electric vehicle users are no longer due to the halfway no power to get off the implementation to worry about, no longer dare not travel due to lack of electricity. Mobile phone users do not worry because the battery died and can not call! The charging station effectively bring convenience.

The structure and principle of description:

(1), the basic structure of the charging stations:
Box-type electric vehicle fast charging stations, junior primary charger (charge) for renewable energy storage battery, storage battery, secondary secondary side fast charger (to charge electric cars), renewable battery maintenance machine, billing control system 6, the cable distribution system, the engine room composition.
The engine room seals and thermostat design, engine room are equipped with the duty office, convenience storm and (2), the working principle:
Usually (night first) grid electricity through the junior primary charger to renewable battery energy storage charge, storage charge there is no time requirement, which can be used current slow charging, the charging current arrangements for charging according to battery power automatically, the largest extent the use of off-peak electricity at night. Need to charge electric cars, electric vehicles, the maximum allowable charge current and voltage through the secondary secondary side fast charger for fast charging electric vehicles, due to the charging process from the storage battery to the electric car "down power" rather than taken directly from the grid, and therefore without any interference on the grid (if to take power directly from the grid power, it would seriously interfere with the grid, not only negatively affects other users, and the threat to power grid equipment).  Get Kang electric vehicle fast charging stationsCharge the cost of the actual amount of charge is very convenient.
Inside the device uses a modular design, with a renewable battery maintenance equipment.
Charging stations using the first time on-site assembly, after the same as the container needed for the overall mobile.
Remote roads and electricity can be used to protect geographical solar and wind power and other forms, the same principle.
