Batteries and Free Fuel based Photovoltaics and Complimentary Wind Energy based DC Power Networks as 100% Source of Electric Power around the Globe

A Review of Extremely Fast Charging Stations for Electric Vehicles

“…These components are not required for DC grid with the net result of cost reduction of XFC and a higher system reliability (due to less number components in the system). Thus, an important aspect of background motivation lays in the end-to-end DC Infrastructure as shown in Figure 2 [15]. The transmission losses caused by AC-DC-AC conversion can simply be averted by adopting a fully DC system.…”

“…The heavy-duty charging cable has additional maintenance issues as they are made of bulky liquid cooled assemblies. The MW level charging cable must be in between 1000 Infrastructure as shown in Figure 2 [15]. The transmission losses caused by AC-DC-AC conversion can simply be averted by adopting a fully DC system.…”

“…Designing the correct algorithm as mentioned in reference [17] is the biggest engineering problem that remains to be addressed in the fast-charging scenario. In retrospect, the authors of reference [15] propose a battery and photovoltaic based charging network for this specific purpose so that the charging infrastructure remains completely separated from the AC grid and the load is minimized. The scope of this paper is to point out the advantages of DC charging and the dependence on solar and or wind as energy sources with batteries incorporated is a new perspective to minimize the stress on an already overloaded grid.…”
