Volkswagen wants to speed up the sluggish Development of the infrastructure for E-cars with mobile fast-charging stations. Such stations can be placed in the group, according to public Parking lots or on company premises. They work according to the principle of power banks, with which Smartphones on the go without a power outlet can be loaded.

The VW column sums up to 360 kilowatt hours of electricity. With a load up to 15 E-cars can charge their batteries at the mobile charging station. At the same time up to four vehicles can load, two AC and DC power connections. Also, the DC-fast charging with up to 100 kW should be possible. The mobile charging point is technically based on the battery package, the VW group uses for its future electric cars.

intermediate storage for Wind and solar energy

these columns are suitable to Potentially relieve the pressure on the power grid and thus reduce the need of new lines. On the other hand, the System requires additional battery capacity, the production of which is energy-intensive and expensive. Volkswagen stresses that the planned pillars of the old E-car batteries can be used.

The first mobile charging stations to be set up Volkswagen in the first half of 2019 in Wolfsburg. By 2020, the columns are to be used in other cities.

With them, it is also possible, irregular electricity from Solar or wind power plants to cache. The case of charging the battery level is below 20 percent, can be replaced the column with charged. The locations of the columns via the App.

The System represents a “decisive step to a powerful network of charging points,” said Thomas Schmall, CEO of Volkswagen group division component. It was a new approach to electric car infrastructure. Their slow Expansion is considered to be a major obstacle in the Development of E-mobility – in addition to the high price of cars and have often used low range.

Other auto manufacturers rely on stationary energy storage

other automakers will allow the used batteries of their electric vehicles a second life. So, Daimler opened in the year 2016 in Lünen with a stationary 13-megawatt-hour storage in 1000 battery systems of the Smart Fortwo electric, the fluctuations in the power grid to compensate.

Used batteries from the Nissan Leaf, the Johan Cruijff Arena, Amsterdam supply with electricity. A memory with a capacity of three megawatts stores the energy of the solar modules on the roof of the stadium and relieved games the power grid in high-demand concerts or football. In addition, the stored energy would be sufficient to supply approximately 7,000 households in the city for an hour with current.
