The integration of energy recovery systems in eBikes is an intriguing proposition. While it's true that the industry is currently focusing on increasing battery capacity, regenerative braking and pedal-based energy recovery are not entirely absent. Some manufacturers have already experimented with these technologies, albeit on a smaller scale compared to hybrid cars.
Regenerative braking in eBikes is possible through a process known as electromagnetic regeneration, where the motor acts as a generator during braking, converting kinetic energy back into electrical energy. However, the efficiency of this process is limited by the weight and rolling resistance of the bike, as well as the limited energy conversion rate of the motor.
Pedal-based energy recovery, on the other hand, is more challenging to implement, as it requires complex torque measurement and control systems. Nonetheless, some companies have developed prototypes with energy recuperation during pedaling, storing the excess energy in supercapacitors or ultracapacitors for later use.
While these advancements are promising, they still face several barriers, including increased cost, complexity, and energy storage challenges. Moreover, the environmental benefits of energy recovery systems in eBikes might not be as significant as in hybrid cars, given the lower energy input and output involved.
In conclusion, while the eBike industry has not entirely abandoned energy recovery systems, the focus remains on improving battery capacity and reducing costs. Nevertheless, ongoing research and development efforts could lead to more widespread adoption of regenerative braking and pedal-based energy recovery in the future, further enhancing the appeal of eBikes for environmentally conscious riders.
