Best practices while using electric bikes

Electric bike are most common form of transportation in China. India is seen as future hub for e-bikes business. Within 3 years India now has more than 125 EV companies. This business is growing steadily but still in nascent stage due to various factors. Most important factor is ignorance of the end user towards EV technology. Hence this article concentrates on the providing best practices while using e-bikes.

Before understanding e-bike’s best practices, Let us understand its concept first. Electric bike has five major components – Battery, Motor, Controller, Charger and Converter. Let us understand the basic functions of these components. Battery is the energy source to power the drive train of e-bike and the functioning of the lighting accessories. Motor drives the wheel taking the instruction from power electronic base controller. Charger is used to charge the Battery. DC-DC converter is used to reduce to standard voltage sufficient to automotive accessories.

Practice the following points to use your e-bike in a better, safer and comfortable way.

Permanent Magnet Motors Introduction And Trends


Induction motor is preferred choice of manufacturer and customer primarily due its robustness, easy manufacturing, and low maintenance. But is this the most efficient motor? Answer is obviously no. Efficiency is function of losses, so let us revisit the Induction Motor losses as shown in figure1. Now if compare these losses with permanent magnet (PM)motor, we would notice that there is rotor copper loss which is almost 15 to 20% of overall losses.
As these losses goes down the cooling requirement of motor can be     reduced.

Article on " Battery Operated Vehicle " in http://www.evhub.in


A battery operated electric vehicle (BEV) uses electricity stored in its battery pack to power an electric motor that turns its wheels. The battery pack is often recharged by connecting or “plugging” it into a wall socket or other electrical source, such as a solar panel. 
Because a BEV uses electricity as a fuel, there are no emissions out of its tailpipe. In fact, it does not even have a tailpipe!
Moreover, it is very friendly on pocket to recharge a BEV. The development of BEVs has made a significant contribution to battery research and to the advancement of electric motors and power electronics used in both hybrid electric and fuel cell vehicles.
