batteries and consequently normal electric vehicles would be a lot lower For instance at the current rate of 190 euros for one kilowatt hour kWh of electrical energy storage a traction battery optimized for daily short dis tance travel costs only 2 470 euros That compares real ly well with the 10 000 euros consumers have to pay for the high energy storage systems of current models But and this is a big but Consumers expect battery elec tric mobility to deliver the same advantages that IC engines do spontaneously available and unlimited mo bility Even an empty fuel tank as a limiting element is refilled in practically no time at one of the countless fuel pumps spread across the country and once filled you re on your way again No electric vehicle provides this type of flexibility at the moment not yet Charging infrastructure as the greatest challenge At least progress in battery cell development has by now made it possible for vehicle developers to put me dium sized automobiles with a range far beyond 300 ki lometers 186 miles on the market A prominent case in point is the Opel Ampera e that thanks to a 60 kWh lith ium ion battery plus sophisticated range management covers about 400 kilometers 248 miles The Hyundai Kona achieves similar distances and other automakers are upgrading their vehicles too knowing full well that many consumers expect higher range as a prerequisite for choosing an electric vehicle German energy utility E ON in a quest for precise information surveyed automotive customers across the country to find out what an electric vehicle would have to deliver in order to be purchased According to the results concern about range appears to be the big gest obstacle For 71 percent of the respondents higher range is crucial for switching to an electric vehicle In ad dition the survey revealed charging times were much too long and the number of charging stations was insuf ficient Some 65 percent of the respondents criticized the current charging infrastructure Dr Jochen Schröder President of Schaeffler s E Mobility Division views the inadequate charging infrastructure as one of the great est impediments to electric vehicle acceptance as well In the case of plug in hybrids this question is not quite as crucial but the drivers of fully electric vehicles de pend on a viable infrastructure Many potential buyers of electric vehicles continue to be deprived of opportu nities to charge their vehicles close to where they live particularly in urban areas where electric cars offer the greatest advantages However Schaeffler s electric mobility expert is not only concerned about the quantity and footprint of charging stations Charging times are currently too long as well I feel that even 15 minutes for recharging will not be permanently accepted by all long distance drivers because they ve become accustomed to filling up on energy for a 500 kilometer 310 mile distance in five minutes Achieving such tank refueling equivalencies for electric mobility poses a huge challenge One possible key to success doubling the current standard voltage of a traction battery from 400 to 800 volts Using this technology Porsche together with Schaeffler clinched overall victory in the 24 Hours of Le Mans on three oc casions The findings gained with the 919 hybrid sports cars have been fed into the development of the future all electric Taycan production model The new peak current offers the major advantage that at a respec tive 800 volt DC charging column up to 350 kW can flow into the high voltage battery For comparison Tesla s superchargers currently achieve a maximum of 135 kW However even with 800 V turbocharging a Taycan has to be plugged in for about 20 minutes to draw electric ity for 500 kilometers 310 miles provided the driver finds a vacant charging column To solve this problem Porsche together with Audi BMW Daimler and Ford has joined the IONITY venture that pursues the aim of es tablishing 400 high speed charging stations with up to 350 kW per charging point across Europe That s a sol id plan for starters Like Schaeffler s expert Schröder the EU sees a need for action as well and is funding the expansion of charging stations with 800 million euros With that the current number of 18 000 fast charging points 22 kW could be clearly more than doubled Of 117 million vehicles under six tons 13 228 lbs of the annual production in 2030 40 will be using hybrid powertrains and 30 each ICE or electric powertrains This means that 70 will still have an IC engine and 70 an electric powertrain More than 260 Source IHS and Schaeffler new battery electric automobile models are planned to hit the market by 2024 70 70 scenario outlook 93
