Evoke Reduces Weight Of Electric Motorcycles With New Higher Energy Density Cells
Evoke Electric Motorcycles is a Beijing company that is trying to establish itself at the higher-end of the Chinese market.
The company was present at the recent 2017 EICMA show in Italy with its new Evoke Urban Classic model and Evoke Urban S (available for the last few years).
Evoke has a rather different approach to the powertrain. It’s using a 19 kW, 117 Nm hub motor.
The battery packs, according to Evoke, now consist of more energy dense cells and improved battery management system, that together enables it to drive around 120 km (75 miles) at 100 km/h (62 mph) or 200 km (124 miles) if measured at a constant speed of 45 km/h (28 mph).
“The new battery management system (BMS) incorporates a faster chip which provides data at a higher refresh rate, giving the rider faster, more accurate diagnostics of the bike. The new BMS also includes an enhanced, built-in balancing algorithm which allows for longer battery pack life and more usable per-charge range, reducing the overall maintenance cost for consumers.”
The Urban S is equipped with a 8.7 kWh battery, while Urban Classic uses a slightly smaller 7.8 kWh.
The battery improvements enabled weight reduction for both motorcycles from 185 kg (in spec) to 169 kg (373 lbs), which is 9%.
