Reference number : GC-2017-Q2-04367, amendment number : , agreement type : G, recipient legal name : Woodward, Lyne (École de technologie supérieure), recipient country : CA, recipient province : nan, recipient city : Quebec|Québec, recipient postal code : nan, program name english : Engage Plus Grants for Universities, program name french : Subvention d'engagement partenarial Plus pour les universités, program purpose english : Recently, e-bikes have been popular because they offer several benefits such as the convenience for riders and_x000D_
no carbon dioxide emission to our environment. However, the high cost and the short duration of battery pack_x000D_
seem to be the biggest drawbacks that prevent e-bikes from widely spreading on the market. In order to reduce_x000D_
the cost, Alizeti, our industrial partner, has successfully developed a solution to convert most existing bicycles_x000D_
into a full featured e-bikes. In this solution, the powertrain system is basically based on an electric-powered_x000D_
roller in contact with the tire which drives the bike by friction. The battery and the drive train are built into a_x000D_
compact enclosure to be fixed on a conventional rear luggage rack. Thanks to this simple configuration, the_x000D_
riders can easily convert their bike into a full featured e-bike at low cost. In order to improve the lifetime of the_x000D_
battery pack, this project will complete the development of an intelligent portable battery charger. The battery_x000D_
pack of Alizeti's e-bike is a 24V/11.6Ah pack made from Li-Ion battery cells. The developed intelligent_x000D_
portable charger will perform with two main advantageous features. Firstly, the impedance of the battery pack_x000D_
will be maintained at its minimum value during the charging process in order to improve significantly the_x000D_
charging efficiency and the lifetime of the battery. This will result in economy for the riders who will not have_x000D_
to pay for frequent battery pack replacement and maintenance. The second feature is that the battery pack can_x000D_
be charged from both AC and DC power sources with a large voltage range, going from 12V to 48V in case of_x000D_
DC power supply and from 95Vrms to 265Vrms in case of AC power supply. With this feature, the developed_x000D_
charger can charge the e-bike battery from all popular available power sources. As a result riders will use their_x000D_
e-bikes more effectively and comfortably. In addition, the developed charger has a size and weight similar to_x000D_
the popular netbook chargers. With these advantageous features, e-bikes can be charged easily with an_x000D_
intelligent manner. Hence, the completion of this project will significantly contribute to widely spread the_x000D_
e-bike on the road by offering users a low-cost but powerful e-bike., program purpose french : Recently, e-bikes have been popular because they offer several benefits such as the convenience for riders and_x000D_
