How Does the Battery of an Electric Bicycle Work?

Electric bikes are very similar to ordinary bicycles. They all have the same components, such as pedals, gears, shifters, chain drives and bicycle frames. But electric hybrid bikes also have electrical parts such as motors and batteries, which enable them to be driven by electricity. So how does the battery of an electric bicycle with pedals work?

Battery Capacity Determines How Far an Electric Bicycle Can Travel

Obviously, the battery provides power for electric bicycle. Therefore, the capacity and output power of electric mountain bike battery are very important. Of course, how long a battery can make an electric bicycle run depends on how much energy the motor uses and the impact of the terrain. The electric bicycle is also equipped with pedals. When the battery is short of electricity, you can drive it by pedaling, just like a normal bicycle. The pedal greatly improves the range of electric bicycles. If you feel tired, you can use electricity to drive your electric bike, which is very convenient.

Old electric powered bikes usually use lead-acid batteries, an old-fashioned battery that is usually used to start cars. Although they are cheap, the drawback is that they are very heavy and charge slowly. At present, lead-acid batteries have been gradually replaced by lithium batteries. Lithium batteries are much lighter in weight, require less maintenance and have longer life. Lithium-ion batteries are considered as the most promising batteries with much of advantages like high voltage, high specific energy, good cycle performance and no pollution to circumstances, etc. Due to the production technology, the difference among single batteries exists inevitably.

Charge It Up

Charging electric cross bikes is a simple thing. You can charge the battery while it’s still attached to the electric road bike, or remove it from the bicycle. When charging, you just need to plug one end of the charger into the socket and the other end into the charging port.

An intelligent battery management system is installed on the electric sports bike, which can prevent the battery from overcharging or undercharging. This means you don't have to worry about your battery being damaged by overcharging. However, if you don't use the electric street bike for a long time, you need to unplug the plug, otherwise the battery will still be damaged.

Lithium battery has the advantages of fast charging speed, large battery capacity and light weight. Moreover, the safety performance of lithium battery is also very good. In normal use, a lithium battery can be used for many years.

Working Principle of Lithium Battery

The positive electrode of lithium battery is made of LiMn₂O₄ and the negative electrode is made of graphite. During charging and discharging, electrons move between the positive and negative electrodes, producing current. 

Environmental Protection

Riding a smart e bike is an environmental thing, it can also save you a lot of money. For example, it only takes about 8 cents to charge your electric bike. That means you can charge your electric bike about 13 times for just $1. 

Although most environmental products are bulky, electric bikes are not. In fact, you hardly notice the existence of batteries during your use of electric bikes. Most electric bicycle batteries are installed under the seat, and you can't even see them from the outside.
