Volkswagen will soon be showing the public its new mobile quick-charging station, the first charging station with the ability to store power, meaning it can be set up independently of the power grid to charge electric cars in temporary public spots.
Working on the same premise as Volkswagen’s new line of EVs (meaning it needs to be recharged as well), the mobile charging station is ideal for public parking lots, temporary charging at large events, on company property, or wherever electric vehicles need a charge, which in the near future may be in a lot of spots. One of its benefits is that a community can judge the effectiveness of a charging station location before committing to a permanent station.
Its charging capacity is 360 kWh, which is good to charge up to 15 EVs, though only as many as four vehicles can be charged at a time, two on DC (direct current) and two on AC (alternating current). DC charging is performed at up to 100 kW, which means a charging time of about 17 minutes.
When the station’s battery falls below 20%, the station is replaced with a fully charged one, since it can be set up quickly and simply. It can, however, also be hooked up to a natural resource generator (such as solar or wind) or plugged into the power grid, and it will keep topping itself up.
Volkswagen is setting up a pilot project in Wolfsburg in the first half of 2019 to test the viability of the mobile stations. The stations will be shipped to other cities and communities in 2020.
“The mobile charging stations are a decisive step toward an efficient network of charging points. The flexibility enables a completely new approach for the rapid expansion of the charging infrastructure,” said Thomas Schmall, Chairman of the Board of Management of Volkswagen Group Components. Cities can, for example, find out the most suitable places for a permanent charging point before making major investments in developing the network. In addition, it will be possible to set up a large number of charging stations temporarily – exactly when and where they are needed.”
The other benefit is that the mobile charging station offers EV batteries a second life — when a spent EV battery is exchanged in a vehicle, it can be inspected and refurbished for use in the mobile charger.
