Battery Swapping Desperately Tries to Stay Relevant

Jason Lomberg, North American Editor, PSD

Battery swapping is that curious legacy solution that just refuses to die. And now one of the leading players, Ample, has debuted a station promising “recharge” times of 5 minutes! We previously spoke about the battery swapping phenomenon and arguably its most high-profile failure. Startup Better Place rai

Fuel Cell Versus Battery Power for Trucks

Click image to enlarge

There are two main types of electric vehicle, categorised by their power source. Battery Electric Vehicles (BEVs) rely on a lithium-ion battery for power. Fuel Cell Electric Vehicles (FCEVs) on the other hand use a fuel cell, which combines hydrogen gas with oxygen to generate electricity. Hydrogen Power Hydroge
