frog design  teamed up with ecotality to create the blink series of electric vehicle chargers. these chargers are designed for
commercial as well as private use, allowing electric car owners to charge up at home and on the go. the design is simplified
and borrows from existing archetypes to make charging easy and intuitive. users simply plug the charger into their car,
much like refilling a car with gas. the colour pallet of black and white was very intentional, avoiding green fatigue. 
the charging units are also very interactive with colour touch screens that give relevant information on energy consumption
and the most inexpensive times to charge up.
