How to Improve the Battery Life of E-bike?

The electric bicycle industry is now in full swing, and many traditional car brands such as Porsche are gradually entering the market, making the electric bicycle boom. We should not only pay attention to the performance and other parameters in the process of buying an electric bike, but also to the battery life and other aspects.

This article will discuss the basics of batteries, how to charge them correctly, how to properly maintain and use them, and how to extend their life to answer all your questions about e-bike batteries.

Understanding the basics of batteries

Types of batteries

There are several types of electric bicycle batteries, each with their own unique characteristics. Here are some of the most common types:

  • Lithium-ion battery (Li-ion): This is the most commonly used type of electric bike battery because it is lightweight, has a high energy density, and is relatively low maintenance. Li-ion batteries are also known for their long cycle life and fast charging capabilities. HiPEAK’s BONA and ELIAS are equipped with 48V 15Ah Lithium-ion battery. The higher power of the battery brings this ebike longer range.
  • Lithium-polymer battery (LiPo): Similar to Li-ion batteries, LiPo batteries are also lightweight and have a high energy density. However, they have a lower internal resistance and can therefore deliver more power, making them ideal for high-performance electric bikes.
  • Nickel-cadmium battery (NiCad): NiCad batteries are known for their durability and ability to deliver high currents. They are also resistant to extreme temperatures and can withstand a greater number of charge-discharge cycles than other battery types.
  • Nickel-metal hydride battery (NiMH): NiMH batteries are similar to NiCad batteries but are more environmentally friendly as they do not contain cadmium. They also have a higher energy density than NiCad batteries and are less prone to memory effect, a phenomenon where batteries lose their capacity over time if they are repeatedly charged before being fully discharged. However, they are still heavier than Li-ion and LiPo batteries.
  • Lead-acid battery (SLA): SLA batteries are the oldest type of rechargeable battery and are still used in some electric bikes due to their low cost and high durability. However, they are extremely heavy and have a low energy density, which means that they are not suitable for high-performance electric bikes.
  • Lithium iron phosphate battery (LiFePO4): LiFePO4 batteries are a type of Li-ion battery that is known for its safety, long cycle life, and ability to deliver high currents. They are also more environmentally friendly than other Li-ion batteries as they do not contain cobalt, a rare and expensive metal that is often used in Li-ion batteries.

The working principle of the battery

Electric bicycle batteries work by storing electrical energy in a chemical form and releasing it as direct current (DC) when needed to power the electric motor. The battery is made up of one or more cells that contain an anode, a cathode, and an electrolyte.

When the battery is charged, a current is applied to the anode, which causes lithium ions to move through the electrolyte and onto the cathode, where they are stored. During discharge, the opposite process occurs, with the lithium ions moving from the cathode to the anode, generating a flow of electrons that can be used to power the electric motor.

Battery life

The lifespan of an electric bicycle battery depends on several factors, including the type of battery, the quality of the battery, how it is used and maintained, and the temperature and humidity conditions it is exposed to. Generally speaking, most electric bike batteries have a lifespan of between 500 and 1000 charge cycles, which can translate to 2 to 5 years of regular use.

Lithium-ion and lithium-polymer batteries tend to have a longer lifespan than other battery types, with some models capable of lasting up to 1000 charge cycles or more. However, factors such as overcharging, undercharging, and exposure to high temperatures can significantly reduce the lifespan of any type of battery.

How to charge correctly?

Pre-charge preparation

Before charging an electric bicycle battery, there are several important steps that should be taken to ensure that the charging process is safe and effective. Here are some common preparations that should be made:
