At the turn of the year, Volkswagen is offering a glimpse of the company’s future mobile quick charging station. It can be set up flexibly and independent of the power supply wherever it is needed: for example, in public parking lots in the city, on company premises, or as a temporary charging point at large-scale events.
The mobile charging station works according to the principle of a power bank – which is familiar to many people with smartphones – but for electric vehicles instead. The charging capacity of up to 360 kWh enables up to 15 e-vehicles, including members of Volkswagen’s new ID. family,1 to be charged in stand-alone operation. Thanks to quick charging technology, the charging process2 only takes 17 minutes on average. If the energy content of the integrated battery set is less than 20 percent, the depleted charging station is simply exchanged for a charged one. If, however, it is permanently attached to the power supply with up to 30 kW via alternating current, the battery pack perpetually recharges itself. In case the charging process is based on renewable Power bank for electric cars – the mobile quick charging station by Volkswagen Group Components power supply, the charging station furthermore allows the temporary storage of sustainably generated power, such as solar or wind energy – and therefore CO2-neutral mobility.
The first mobile quick charging stations will be set up as early as the first half of 2019 in Volkswagen’s hometown as part of a pilot project, and will support the expansion of a charging infrastructure in the urban area. As of 2020, the charging station will also be implemented in other cities and communities.
The mobile charging stations can be set up at defined points, for example, spread out across a city. The flexible locations can be easily found via the Internet or apps. Each charging station enables DC quick charging with up to 100 kW. In addition to electric cars, e-bikes can also be charged. Up to four vehicles can be charged simultaneously: two with DC and two with AC connections. The total battery storage capacity of up to 360 kWh is sufficient for up to 15 e- vehicles. There is also the possibility of connecting to the power supply directly, allowing the station to be charged with up to 30 kW via alternating current by means of a permanent standard grid connection. This enables charging points for electric vehicles to be set up quickly and simply, without any structural changes or major financial outlay. The battery pack in the charging station can be recharged around the clock thanks to the direct power connection. This time-independent recharging, and therefore buffering of power, also considerably reduces the strain on the power supply at peak periods.
An efficient network of charging points is regarded as one of the basic infrastructural prerequisites for convincing customers to buy electric vehicles such as the Volkswagen brand’s future I.D. family.1 Accomplishing this is one of the major challenges Volkswagen Group Components and others must tackle to ensure the breakthrough of e-mobility. As of January 1, 2019, the Components division is an independent business unit within the Volkswagen Group. The mobile charging station is an in-house development with the goal of developing a closed life cycle for the battery. The start of production is planned for 2020.
