To go far, the electric vehicle must either have a large battery or charge quickly. The latest models have already seen a dramatic increase in battery capacity. Today, for example, a Hyundai Kona Electric or a Kia e-Nero has 64 kWh, 3.2 times more than the first Renault Zoe, which came on the market in 2013. This allows them to drive 400 km under normal driving conditions. But that's not enough to go on vacation. Some Tesla are doing better, but at an elitist pace.
The right compromise is therefore to provide enough autonomy for daily use and to be able to "refuel" in a very short time. In this area, the Tesla can load at certain terminals (compressors) with a capacity of 120 kW. We recover approximately 150 km autonomy in 15 minutes, For an electric vehicle, it is not enough to replace a thermal vehicle one day. For this reason, the Volkswagen Group, Daimler, the BMW Group and the Ford Motor Company have been founded the joint venture Ionity.
The "full" in 15 minutes!
All studies show that in the near future during long journeys with electric vehicles 25% of the refills are done in public superfast stations, Ultrafast means a power of 125 kW or more. With 150 kW, the new Audi e-Tron electric restores about 10 km of autonomy every minute. A full 80% will be done in 30 minutes.
The Taycan-Porsche can drive after a quarter of an hour a 250 km long highway
However, Ionity goes further with terminals that can deliver 350 kW under tension in the range of 200V to 920V in direct current. In other words, 6 minutes is enough to charge a 100 kWh battery at 45% and 15 minutes to be "full" at 80%.
The ionity charging standard is the Combo 2 CSS, now selected by all manufacturers for Europe (except Nissan!). Connection to the mains is via medium voltage (15 000 V to 30 000 V). However, the consortium also wants to generate renewable energy locally (solar, wind …) and use batteries as a buffer. This approach solves the main problem of fast charging systems: the availability of power in the network, regardless of whether the port size or the power requirement is at peak consumption.
400 stations in Europe
By the end of 2019, the Ionity network will be available 400 stationsdistributed evenly across the major European axes. today France, Germany, Austria, Denmark, Norway, Spain, Portugal and Italy start to be equipped.
In France, finally, 80 petrol stations will be on highways. The first two were opened in autumn 2018. You are on South Anger Gate (A11) and Long View tours (A10). At the beginning, they pay the price of The fee is fixed: 8 euros, This is very interesting if you have a vehicle that is capable of making the load ultra-fast, such as the Hyundai Kona Electric or the Kia e-Niro (possible load up to a power of 77 kW). The cost per kilowatt hour then amounts to less than 0.18 € (average cost per kWh in France: 0.15 €). The payment is done without subscription via an application on a smartphone or an RFID badge provided by some operators, such as the Chargemap Pass in France.
