What is the lifespan of lithium batteries for electric bicycles? Introduction to the lifespan of lithium batteries. Do friends who use electric bicycles know how many years the lifespan of lithium batteries in electric bicycles is? I believe the vast majority of consumers have heard that the lifespan of lithium batteries is "500 times". After 500 charge and discharge cycles, the battery will "end its life". Many friends, in order to extend the lifespan of lithium battery packs, only charge them when the battery is completely depleted. Is this the correct charging method? Today, let's discuss the issue of the lifespan of lithium battery packs for electric bicycles.
Lifespan of lithium battery pack for electric bicycles
The lifespan of lithium battery packs is closely related to the daily use and maintenance of users.
A charging cycle means the process of the battery's entire charge from full to empty, and then from empty to full, which is not equivalent to charging once. For example, a lithium battery only uses half of its capacity on the first day, and then charges it slowly. If it continues like this the next day, charging half of it and charging twice in total, this can only be considered as one charging cycle, not two. Therefore, it may usually take several charges to complete a cycle. After completing each charging cycle, the battery capacity will decrease slightly. However, the battery capacity is very low and the range is very small. After multiple cycles of charging, high-quality batteries still retain 80% of their original capacity. Many lithium powered products continue to be used as usual after two to three years. Of course, lithium batteries still need to be replaced at the end of their lifespan. And the so-called 500 times refers to the manufacturer achieving around 625 rechargeable times at a constant discharge depth, reaching 500 charging cycles. Due to various influences in real life, especially the non constant discharge depth during charging, the "500 charging cycles" can only be used as a reference for battery life.
After completing a charging cycle, the capacity of lithium batteries decreases slightly, but this proportion is very small. High quality lithium battery packs still retain 80% of their original capacity after multiple charging cycles. Many electric vehicle lithium batteries can still be used normally after three years of use, so it still depends on the quality of the lithium battery.
Methods for extending the lifespan of lithium batteries in electric bicycles
If you want to increase the lifespan of electric vehicle lithium batteries, you should pay attention to the following points when using them:
1. The smaller the discharge depth of the battery each time it is used, the longer the service life of the battery. Therefore, regardless of the capacity of the lithium battery pack used, users should develop a good habit of charging as needed.
2. High current discharge can cause certain damage to electric bicycle batteries, so please use pedals to assist during starting and uphill driving.
3. When the battery needs to be left for a long time, it must be fully charged and regularly replenished, usually once every 1-2 months. For users with a daily transportation distance of less than 30 kilometers, if the motor, controller, charger, and other factors are all good and the usage method is not improper, the minimum service time of a good set of electric bicycle batteries should be guaranteed to be more than 1 year.
How to choose a lithium battery electric bicycle
1. Look at the brand
Currently, there are many brands of electric bicycles. Consumers should choose brands with long operating time, low repair rate, good quality, and reputation. For example, choosing a company that has passed the ISO9001-2000 quality management system certification. If you're not sure, you can buy some big brand electric bicycles,
2. Heavy Service
At present, the components of various electric vehicles are not yet universal, and maintenance cannot reach socialization. Therefore, when choosing an electric vehicle, it is important to pay attention to whether there is a dedicated maintenance service department in the local area. If you ignore after-sales service for the sake of affordability, it is easy to fall for it.
3. Choose a car model
Electric bicycles can generally be divided into four types: luxury, ordinary, front and rear suspension, and lightweight. The luxury model has complete functions, but the price is high, while the ordinary model has a concise structure and is economical and practical; Lightweight and flexible, but with a short travel distance. Binglan electric vehicles remind consumers to pay attention to this when making purchases.
4. Check accessories
The strength and performance requirements of electric bicycle components should be higher than those of bicycles. When making a purchase, users should consider the quality of the selected parts for the entire vehicle, such as whether there are defects in the welding and surface of the frame and front fork, whether all parts are manufactured well, whether the double supports are sturdy, whether the tires are branded, and whether the fasteners are rust resistant.
5. Consider extending the mileage
A set of new batteries with a capacity of 36V/12Ah generally has a range of about 50 kilometers. In general, the longest distance for daily cycling is about 35 kilometers, which is more suitable (due to road conditions affecting the actual range). If the longest distance for daily cycling exceeds 50 kilometers, it is necessary to consider the possibility of two interval charging within a day. If there is no such possibility, it is not suitable to choose an electric bicycle.
Sometimes it's not that the quality of the electric vehicle you buy is poor or the battery is not good, but rather that your charging method is improper, leading to premature battery loss. Just remember these tips!
