However, the standards committees are concentrating on cables with contacts at the end, with Europe the laggard. The European Commission and European standards organizations hope for a common interface in general use by 2017. Quixotically, they hope their standards will become global despite the fact that North America, China and Japan are showing more urgency, already pushing for their standards to be adopted globally. Nonetheless, there are no agreed and adopted standards anywhere for the fastest "Level 3" form of charging  -- top request for public places. If Level 3 can be made safe and affordable, charging some EVs in ten minutes is possible if they have the right type of lithium-ion battery.  Fastest charging means expensive hardware and installation at present, often with a large lithium-ion battery and ultracapacitor bank in the charger. Copying the 40MW delivery of a gasoline station is not necessarily feasible, safe or affordable yet. The forecast of the 2015 split between options is shown below. Discrete Level 1 stations will be modest in number because so many EVs will be charged slowly using a regular domestic power socket, the inverter being in the vehicle itself.Percentage split in numbers of EV charging stations sold worldwide in 2015. Level 1:    6 percentLevel 2:  80 percentLevel 3:  14 percentSource IDTechEx report "Electric Vehicle Charging Infrastructure 2011-2021"

The super ant’s attraction towards electricity is stronger than its compulsion to eat or drink, meaning it can gnaw through electricity cables and nest in electrical equipment and plug sockets.  These ants usually nest in electrical items and this means they can pose a fire risk and when they swarm can cause blackouts.
