Our phones have powerbanks- yes. But the technology of Electric cars or e-Cars is fast-paced. Charging stations for electric cars are the ‘fuel’ stations of the future. But looking critically, it’s not exactly possible to simply place them on every street corner: they have to be connected to the respective power grid. Volkswagen is now announcing a solution that can theoretically be set up quickly and anywhere – Volkswagen Powerbanks for Electric cars.
Volkswagen is offering a glimpse of the company’s future mobile quick charging station ie Powerbanks for electric cars. 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, to be charged in stand-alone operation. Thanks to quick charging technology, the charging process
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 supply, the charging station furthermore allows the temporary storage of sustainably generated power, such as solar or wind energy – and therefore CO2-neutral mobility.
“Our mobile charging stations offer a further crucial advantage,” says Mark Möller, Head of Technical Development at Volkswagen Group Components. “It is only when an electric car is charged with sustainably generated power that it can claim CO2-neutral mobility. Our charging station is the first to offer the possibility of temporarily storing sustainably generated power.” For example, the charging station can be charged specifically with solar or wind energy, which is then transmitted to the electric vehicles during charging. Technically, the mobile charging column is based on the battery pack of the Volkswagen Group’s Modular Electric Toolkit (MEB). On the one hand, this offers the advantage of quick scalability and, on the other hand, the charging station allows batteries from electric vehicles to have a second life. This is because a battery loses charging capacity over time. If a vehicle battery has a defined, reduced residual capacity, it is exchanged. If this battery subsequently passes a thorough analysis, it can be reused in a mobile charging station.
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 of the Powerbanks for electric cars is planned for 2020.
