The electric bike battery is a central element of any electric bike (VAE) which is part of the electric bike parts, influencing the autonomy, power and lifespan of the bike. Understanding the key features and specifics of the different batteries available will help you choose the one that best suits your needs.
1. Technical characteristics of an electric bike battery:
a. Capacity (in Wh)
The capacity of an electric bike battery is measured in Watt hours (Wh) and determines the range of the bike.
Formula: capacity = voltage (V) x current (Ah)
Common examples:
300 Wh: For short or urban journeys.
500 Wh: Ideal for medium or hilly journeys.
750 Wh and more: For long distances or mountain outings.
b. Voltage (in V)
Voltage influences motor power:
36 V: Standard for urban and leisure electric bikes.
48 V: Offer more power, ideal for electric mountain bikes or cargo bikes.
c. Cell Type
Lithium-Ion (Li-Ion): Standard for its light weight, high energy density and extended lifespan.
Lithium Iron Phosphate (LiFePO4): More durable and resistant to overheating, but heavier.
Nickel Metal Hydride (NiMH): Rare, replaced by lithium.
d. Autonomy
Autonomy varies depending on:
Battery capacity.
The weight of the cyclist and the bicycle.
The terrain conditions and the assist power used.
e. Cooldown
2 to 8 hours: Depending on the capacity and type of charger used.
Fast chargers help reduce this time, but can affect battery life.
f. Lifetime
Recharge cycles: A battery lasts on average between 500 and 1000 complete cycles, or 3 to 5 years of regular use.
After 500 cycles, capacity may decrease by 20-30%.
