Personal zero emission transport for the city of the future ('PRAZE')


The objective of PRAZE is to develop a zero emission personnel 2-wheel vehicle for city driving, with over 60km range per battery charge during the ECE 47 urban cycle, compatible with a future product cost of under 2,200 Euro. The PRAZE vehicle is expected to have a primary energy efficiency of 191Wh/km for the ECE 47 urban cycle, compared with 241 Wh/km for current scooters, and 346 Wh/km for an equivalent thermal scooter. The PRAZE vehicle will use a high efficiency in wheel, brushless, gearless motor controlled by microprocessor, with regenerative braking to improve energy efficiency. Bipolar Ni-Zn batteries will be developed with a specific energy density of 70Wh/kg compared with 44Wh/kg for existing Ni-Cad batteries. Bipolar Ni-Zn batteries will potentially have 40% of the Ni-Cad production cost. The PRAZE vehicle will be tested and its performance modelled. Results of the project will be widely disseminated.
