NAWA Technologies, maker of next-generation ultra-fast energy storage systems, revealed NAWA Racer, a stunning zero emission motorbike concept which features a ‘hybrid’ battery.
Appeared at the Consumer Electronics Show (CES) in Las Vegas, NAWA Racer combines NAWA Technologies’ ultracapacitors – which offer ten times more power and five times more energy than existing tech – with conventional lithium-ion cells. The hybrid system offers ultra-fast charging, incredible energy recovery and high power output thanks to the ultracapacitors, and a long continuous range thanks to better lithium-ion management.
Inspired by the original café racers of London in the 1960s, which were lightweight, powerful bikes used for short, quick rides between cafés, NAWA Racer builds on these themes, boasting a raft of efficiency benefits that make it perfect for the city, with features other e-motorbikes cannot offer.
Located in the bike’s top tank area is an arrangement of NAWA Technologies’ own ultracapacitors, known as NAWACap and offering 0.1 kWh, which boost a lithium-ion battery mounted low in the chassis where the internal combustion engine would otherwise be.
Re-using more than 80 percent of the energy captured from regenerative braking – lithium-ion can only re-use 30 percent – NAWACap brings major leaps in efficiency, allowing NAWA Racer to use a much smaller lithium-ion battery than would otherwise be possible: just 9 kWh, around half the size of a conventional electric sports bike’s battery.
The NAWACap pack itself is lightweight too, weighing as little as 10 kg, and combined with thebike’s carbonfibre frame and composite body panels, NAWA Racer tips the scales at just 150kg, a weight saving of 25 percent over conventional electric sports bikes.
