An intriguing cure for range anxiety allows any EV to take a road trip
The three most common cures for range anxiety are as follows: a larger and more expensive battery (Tesla), a backup gasoline engine (Chevrolet Volt, etc.), and well-developed charging infrastructure (Nissan, Tesla). Is it time to make way for a fourth remedy for this troublesome ailment?
The German firm ebuggy is developing what amounts to a battery on wheels; a trailer packing 85 kWh of energy that can add 300 miles of range to support long drives in otherwise range-limited electric vehicles (via Ecomento). Their newest concept is still in the rendering stages but the advantages and disadvantages are already clear.
A backup battery that is used only when needed is in theory an ideal answer to one of the greatest shortcomings of battery electric vehicles: most have limited range and therefore are not suited for long drives, restricting them to daily commutes and rendering them impractical unless a second vehicle is in the garage. If a BMW i3 can pick up a battery trailer on the weekend for the trip to visit relatives in the next state, it instantly becomes viable for many more potential buyers.
