Is String Cell battery technology the future for EVs?
When it comes to finding a way to charge EVs more quickly, human ingenuity has come up with some pretty wide-ranging solutions, from battery-swapping to flow batteries that store energy in tanks of liquid electrolyte. The latest innovative idea comes from startup Tanktwo, and is called a String Battery. Tanktwo’s system replaces a vehicle’s battery pack with a container filled… Read more »
2015 VW e-Golf ushers in an era of interchangeable drivetrains for every Volkswagen model
Rising above the waters of the Mittelland Canal in Wolfsburg, Germany, four iconic smokestacks cut through an otherwise sparse skyline. These are the most recognizable – and among the last – vestiges of the original Volkswagen factory from 1938. Symbolically, however, the smokestacks represent much more than the symbols of a power plant that –… Read more »
A better way to battery-swap?
The idea of battery swapping for EVs has been around for some time, but the reality has not been auspicious. Better Place bet on the concept and went bankrupt.
