Powerbanks for electric cars: Volkswagen announces mobile charging station

At the turn of the year, VW released a small teaser video, including a press release, which could make one or two lines of concern disappear from the minds of future electric auto drivers.

The firm has revealed details of a new mobile charging station with the capacity to charge up to 15 EVs when operating separately from mains electricity systems. The total battery storage capacity of up to 360 kWh is enough to supply juice for up to 15 electric vehicles, with an average charge time of 17 minutes thanks to quick charging tech.

The station is built around the principle of a power bank, which most people are familiar with, as a way of getting a little more charge on the go when our phones won't make it through the day. They could either be swapped out for another one when they reach 20 percent of their capacity, or be plugged in at a maximum power of 30 kilowatts, to charge themselves at a slower, steadier rate that could help reduce the strain of peak electrical-demand periods-and if used in the USA, the chances of costly demand charges.

Each charging station enables DC quick charging with up to 100 kW. How this exchange takes place, or whether the whole charging station is simply exchanged for a new one, is unfortunately still unknown.

The IOC lifted its ban on Russian Federation at the end of the Pyeongchang Winter Olympics. But Wada said on 21 December it had been unable to "complete its mission".

VW notes that these stations could also be used as smaller-scale buffers for storing solar or wind energy from nearby sources.

Company chief of technical development, Mark Möller said "our mobile charging stations offer a further crucial advantage - it is only when an electric vehicle is charged with sustainably generated power that it can claim CO2-neutral mobility". As of 2020, the charging station will also be implemented in other cities and communities, possibly in large-scale events as well. This offers quick scalability, and the charging station allows batteries from EVs to have a second life. Particularly in cities, these charging stations with integrated rechargeable batteries can ensure that the power grid does not collapse as the number of e-cars increases.

The first boxes will be produced this year as part of a pilot scheme in Volkswagen's home town of Wolfsburg, where they will support the city's infrastructure expansion. Let us know in the comments.
