An electric bicycle is based on an articulation of three main parts, the bicycle itself (frame, peripherals and mechanical transmission), the engine and the battery which stores our dear small electrons. Also called “battery”, the battery of an electric bike is in a way the energy reservoir of the assistance system.
We will examine the battery in this article so that you can better choose or understand how your (current or future) electric bike works.
Battery safety and reliability
The chemistry of electric bicycle batteries is classified as a dangerous substance UN 3480 class 9. In order to make the batteries stable and safe, “serious” manufacturers use an electronic cell management system which avoids the slightest problem, particularly in overheating.
This is why batteries represent an important part of the budget of an electric bike because they are extremely reliable and secure with electronic safeguards. Therefore, one should be wary of the too low prices of electric bikes.
The internal assembly and the casing of the battery are equally important so that the product complies with the IP54 standard which guarantees the battery waterproof against splashing water and dust.
Impact resistance is also essential given the exposed use of an electrically assisted bicycle and in particular an ATV.
What factors affect pedal battery life?
Battery life is closely related to cycling and it depends on many parameters and factors that directly affect it. It can vary from single to triple (and more) depending on:
Course Profile (Medium, Regular, High Accommodation)
Such a route (Citizen: with many energy stops in the country / Resume: Relatively smooth, smooth and linear, on lane mountain roads where a long-term electric battery is used in hell) Even For runners, the difference in height can be very important as a mountain bike).
Motorcycle type and weight: For example, a 28kg Dutch bike with an upright motorcycle position that offers significant wind resistance / 18kg fitness bikes with a maximum aerodynamic configuration.
Tire type (rubber, texture, size, and part), but above the wheel inflation! Using a low-wheeled electric motorcycle can lose up to 30% autonomy (in kilometers).
Climate and external conditions: Cold naturally loses its autonomy. The maximum temperature is between 15 and 25 C.
For example, a low-energy road is a lightweight electric motorbike that roams the plains in the open and does not stop or restart, with properly inflated tires and support in the “Echo” mode. In fact, the most expensive form of energy is a mountain road with uneven surfaces, a wide-tiered motorcycle, and a light-flowered motorcycle in a very supportive mode.
The future of eBike batteries
The benefits of massively funded research for electric car batteries will continue to trickle down on EV battery technology. The trend is currently increasing mass power. In the years to come the standard of the batteries is therefore likely to pass to 600 WH then 700 WH…
“Metal battery” technology or the development of a still confidential technology developed in the laboratory may help to create disruption. This will allow the carrying of 1000 WH while keeping a similar weight.
The future is undoubtedly electric!
