Faulty refueling is impossible at the electric charging station
Choosing either the wrong cable or charger wouldn’t have serious consequences in this case. The charger with a charging power of 3.7 kW also works with the three-phase 22 kW cable. Conversely, the better-equipped onboard charger with three phases can also be charged with a single-phase charging cable. In both cases, the electric current only flows via one phase. Renault has recently come up with a special treat – the French have patented a charging system that automatically adapts to different AC charging powers of up to 22 kW. Volkswagen, on the other hand, is now equipping some models with a two-phase charger to achieve a charging power of 7.4 kW. However, a two-phase cable isn’t available on the market, not even for its weight in gold. If you want to make the best possible use of charging power, you need a three-phase cable with a charging power of 11 kW.
E-Mobility: One strong type dominates AC charging infrastructure in Europe
The use of hardware at the ends of a charging cable, however, is clear. “According to the charging station regulation (LSV), public charging stations for AC charging require the use of a Type 2 plug connection in accordance with EN 62196,” knows DEKRA expert Michael Ringleb. The infrastructure for AC charging is therefore primarily geared towards Type 2. Charging stations and wallboxes always have Type 2 couplings, while vehicles on the road are equipped with Type 2 sockets. The proper charging cable follows the pattern “Type-2-on-Type-2”. However, some Japanese and French vehicle manufacturers still have models on offer that are equipped with Type 1 sockets. For such cases, there are charging cables with a Type 2 plug for connection to the charging source and a Type 1 plug for the car.
DC charging stations move charging speeds into high gear
Charging Mode 4 can be described as the turbo variant of electric charging with direct current (DC). Filling up for a range of 100 kilometers in just a few minutes is no problem at DC charging stations. One of the reasons why the system really pushes the pace during charging is that it supplies the electric car directly with the direct current. A rectifier installed in the charging station eliminates the need for a detour via the onboard charger in the vehicle. The power spectrum for fast charging ranges from 50 kW for simpler systems to 350 kW for high-performance charging stations. In each case, the battery management system of the electric car decides at what power level the direct current ultimately flows into the battery. Incidentally, the charging cable is permanently installed in fast charging stations.
