NC State team develop medium voltage fast charger; up to 350 kW in next version

Green Car Congress

Researchers at North Carolina State University have built an electric vehicle fast charger that is at least 10 times smaller than existing systems and wastes 60% less power during the charging process, without sacrificing the charging time. of the power is used to charge the vehicle, rather than being wasted as heat.

Kinetic Traction Systems launches with trackside flywheel energy storage technology for rail

Green Car Congress

Regenerative electric trains convert kinetic energy into electrical energy during braking. By capturing and storing the energy normally wasted to resistor banks, the system cuts energy use both by eliminating unnecessary resistor heat production and the station’s HVAC demands to remove that excess heat.
