NAWA Technologies, maker of next-generation ultra-fast energy storage systems, reveals NAWA Racer, a stunning zero emission motorbike concept which features a world-first in electric powertrains: a ‘hybrid’ battery.
Appearing at the Consumer Electronics Show (CES) in Las Vegas on 7th January 2020, NAWA Racer combines NAWA Technologies’ revolutionary ultracapacitors – which offer ten times more power and five times more energy than existing tech – with conventional lithium-ion cells.
Marking the first time an electric motorbike has used ultracapacitors, the hybrid system offers the best of both worlds: 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.
Next-gen ultracapacitors: the key to unlocking a hybrid battery
The basis of NAWA Racer’s advantage is the company’s carbon-based ultracapacitors, which charge and discharge in seconds, capable of picking up energy from regenerative braking and supplying it back to an electric motor very quickly. They can do this millions of times over without degradation, offering very fast energy transfer, unlike lithium-ion. But although they have five times more energy storage than existing technology, lithium-ion does still offer greater overall capacity.
By integrating these ultracapacitors into a lithium-ion system, the result is a battery that has much more efficient overall performance, greatly reducing the charge and discharge cycles the lithium-ion battery performs, extending the life of the entire system.
Regardless of electric vehicle, from motorbike to car, the efficiency improvements made by a hybrid ultracapacitor battery system can reduce the size of the lithium-ion battery by up to half, or extend the range by up to double – or a combination in between depending on use. This is especially the case where there is a lot of braking and accelerating, such as in an urban area.
