There are plans to increase the charging rate during long-distance trips. This is one of the reasons why several manufacturers are working on solutions for high power charging (HPC) with values up to 350 kilowatts. In comparison: This is three times the power that Tesla uses in his super charger with 120 kilowatts. The HPC focuses also on higher voltages. Future systems will then use even 800 volts instead of 230 volts or 400 volts. This has quite a few advantages: The charging time will decrease and the cable diameters required will be reduced and thus the weight of the components installed in a vehicle.
About 10,700 public charging points on 4,730 charging stations are available to everybody who is driving on a German road. 530 of them are quick-charging stations. This was the official status as of September 2017. Preliminary estimates of the German association of energy and water suppliers (bdew) say that by the end of 2017 this number will have increased to even 12,500 charging points and 850 quick-charging points. The German ministry of transport plans to cooperate with "Autobahn Tank & Rast", a German highway restaurant and gas station company to equip all of this company's service stations along German highways with quick-charging stations and parking lots for electric vehicles.
Since the upturn in renewable energies, electricity supply has been undergoing a global transformation. Electricity which is generated locally and renewably should be distributed intelligently, stored efficiently and consumed sensibly – whether in private homes, the public grid or transportation.
The market for electricity storage has grown rapidly in recent years and has gained international momentum - for example in the USA, the United Kingdom and Australia. In Germany alone, according to figures from the German Solar Industry Association, 30,000 new solar energy storage units were installed last year – a tripling within three years.
