HOW MANY CHARGING CYCLES CAN YOU EXPECT TO GET?

When we talk about how long a lithium-ion battery lasts, we&#;re ultimately talking about how many charging cycles it has. However, the number of charging cycles depends on how you charge your battery and what you consider a charging cycle. Do you charge your battery at the end of the day? Do you change them as soon as you finish using the tool&#;or do you pop them on at lunch so they&#;re topped off when you return to work? Lastly, battery configuration and capacity play a part, as do ambient storage temperatures.

Unfortunately, most manufacturers define a charge cycle as any time you pop the battery on the charger and let it start working. While one of the strengths of lithium-ion battery is the lack of cell memory, you can still exhaust the maximum longevity of the cells (and the pack) by charging them more frequently than you need to.

At this point in time, most power tool manufacturers claim you should expect to get over 1,000 charge cycles out of any given battery. That equates to 2.7 years if you charge your pack once per day or 3.8 years if you only factor in a 5-day week. Some manufacturers claim 2,000 charge cycles, in which case you can double those numbers.

How many kilometers does the 48V lithium-ion battery run when fully charged?

The battery life of the 48V lithium-ion battery for sale is related to the capacity (Ah) of the battery itself and the motor power (W) of the electric vehicle. Now the standard electric bicycles on the market generally use 48V 12Ah lithium battery and 350W motors. With the development of battery technology Their theoretical battery life can reach 50km, and the actual battery life is determined by the weight of the passenger and the weight of the vehicle.

How many kilometers a 48v lithium-ion battery can run with full power depends on the battery capacity, motor power, and load capacity. Generally speaking, 48V 12Ah, 350w lithium battery can run 50km. The 48v 20ah lithium ion battery pack can run 70km. The 72V 22Ah lithium battery can run 90km.

How many hours does it take for a 48v lithium-ion battery to be fully charged?

The charging time of a 48v lithium-ion battery has nothing to do with the voltage. It mainly depends on the capacity of the lithium-ion battery and the power of the charger. Charging time = lithium battery capacity ÷ charging current. For example, if a 48V 20Ah lithium-ion battery uses a regular 48V 2A charger, the theoretical charging time is 2 hours, that is, 20Ah÷10A=2h, but in actual charging, the constant current is switched to the constant voltage mode, and the final trickle charging takes a long time. So under normal circumstances it is about 3 hours. In the same way, if you choose a 48V 5A charger, you need 20Ah÷5A=4h, but there is also a trickle time, so it is about 5 hours.

HOW LONG DO LITHIUM-ION BATTERY LAST IN STORAGE?

How long lithium-ion battery last when used is one thing&#;but what about when you store them? After all, that might affect whether or not you want to pick up that &#;used&#; battery at the flea market.

A number of factors affect a battery pack&#;s lifespan on the shelf. Let&#;s start with some best practices. You want to store your battery at approximately 50% charge if you don&#;t intend to use them again within a week or so. Some manufacturers may have slight variations on that, but in general, 50% ensures you don&#;t decrease the battery storage capacity while it sits.

From time to time you also need to check your battery packs as they might drain slightly. Ensure the packs don&#;t completely drain by keeping them around 50% or whatever level the manufacturer recommends. Do that, and you can expect your battery to last up to 3-5 years in storage.

Methods to Prolong the Li-ion battery lifespan

Keep the battery at moderate temperature: High temperatures can reduce battery lifespan, so storing or using Li-ion battery at a moderate temperature range of 5°C to 20°C is recommended.

• Partial discharge and charging: Discharging and charging Li-ion battery partially rather than completely can prolong their life. Avoiding deep discharges above 50% DOD can also help extend battery lifespan.
• Maintain moderate SOC levels: Extreme SOC levels can cause capacity loss and shorten battery lifespan. Maintaining Lithium-ion battery at an intermediate SOC level can minimize battery degradation and prolong battery life.
• Avoid heat exposure: Exposure to high temperatures during battery use or storage can increase SEI thickness and trigger electrolyte oxidation, leading to capacity loss and reduced battery lifespan.
• Store battery properly when not in use: When not in use, store Li-ion battery at around 50% SOC and protected from extreme temperatures and humidity levels.
• Avoid fast charging and discharging: Rapid charging or discharging can generate excess heat, which may cause damage to the battery&#;s internal components over time, reducing its overall lifespan.
• Use original equipment manufacturer (OEM) chargers: Using OEM chargers designed specifically for Li-ion battery ensures that they receive the correct voltage and current, preventing damage and prolonging their lifespan.

5 Factors Affecting Charging Time of Electric Bike Battery

• The battery charges faster with a higher amp charger than one with a lower amp. But high amp chargers may damage your battery therefore, I would recommend you use the charger that your manufacturer or ebike brand provided.
• The state of charge also affects the charging time, If your ebike battery is already low or zero percent, it will take a long duration as compared to charging a partially charged (40%) battery.
• Avoid charging your ebike battery when it has a high temperature because it will take a long time to charge as well as reduce the battery&#;s lifespan.
• Branded Lithium-ion battery are charged quickly as compared to traditional battery. So, always get a top-quality li-ion battery.
• Higher the capacity, the longer the duration to charge the ebike battery and vice-versa. For instance, A 36v ebike battery would take less time to charge as compared to a 48v battery with a 3 amp charger.

Is the Investment in Lithium-Ion battery Worth It?

In comparison to the outdated lead-acid battery, lithium-ion battery are undoubtedly a superior option. They are lighter, have a higher power-holding capacity, and a lower rate of self-discharge. Additionally, they demand less maintenance and possess an extended service life. While they may be more expensive initially, the overall savings they provide are noteworthy. We therefore consider lithium-ion battery a valuable investment. They offer a reliable and hassle-free means of storing substantial amounts of power, which can come in handy when needed the most.

Conclusion:

The lifespan of a 48V lithium-ion battery depends on several factors, including charge cycles, depth of discharge, temperature, charging practices, storage conditions, and battery chemistry. While an average lifespan of 5 to 10 years is typical for a well-maintained battery, individual usage and maintenance practices play a significant role. By understanding these factors and adopting appropriate measures, users can optimize the lifespan of their 48V lithium-ion battery and ensure their longevity in various applications.
