The vehicle industry is challenged, because electric vehicles are no longer niche products today. A new era is also dawning for those responsible for renowned brands, as motorists are demanding more and more choice and performance. There is a lot of research and testing going on, because electromobility is not actually a core business of vehicle manufacturers, even though it is basically "cars". Topics such as charging performance, battery safety or new services are at the top of the checklists. Companies are transforming themselves from traditional automakers into systems providers for mobility, offering their customers tailored solutions, whether at home or on the road – and the competition never sleeps. Record-breaking reports are piling up: short loading times. Longer ranges are the trump card. Audi informed z.B. About his e-Tron, which can charge up to. Up to 150 kW in 30 minutes to tackle the next long haul. 400 km range in the WLTP driving cycle is no longer a rarity.
A scenario: dancing light flash and pulsating bruzzle above the car roof
The Faraday cage of the Siemens high-voltage test facility at Schaltwerk Berlin measures 42 by 32 by 25 m. In the world's largest production facility for switching technology, a team of electricians researches. Engineers a lightning impulse voltage of up to three million volts. The Parabelhalle, built in 1958, houses a house-high surge generator for this purpose. In the middle of it all: the Audi e-tron prototype. A flash of light dances over the roof of the car with a pulsating ripple and illuminates the 25 m high hall. The experts have directed a voltage surge specifically at the car. This experiment is emblematic of a millennia-old dream of mankind: capturing lightning and harnessing its energy. Although it is still not possible to charge an electric car with lightning, engineers have come one step closer to the vision of "lightning-fast charging. The production version of the Audi e-tron prototype will be the first car on the market to be able to charge at up to 150 kW. In addition, sophisticated systems in the car provide information about suitable routes with charging points. Consider thereby also equal the state of charge of the battery. Taking into account the current traffic situation, the arrival time will incl. The necessary charging time is calculated.
Charging at home: a joint effort
From very simple to ultra-technical: There are now a wide variety of solutions for charging at home. Today, different industry players need to work together to be successful: Car manufacturers, charging infrastructure providers, electric contractors, EVU, solar specialists, architects, etc. Care about their customers' preferences. This is also creating new cooperation among the industries. …And this is probably just the beginning. It will only be a matter of time before the offers are fully integrated into smart home solutions. Then the car will be according to the schedule of the owner; charging status or pre-air conditioned the car will be ready at the location. In a further step, also autonomously bring its passengers to their destination.
