With the arrival of winter, extra attention must be paid to the maintenance of electric bicycle batteries. Low temperatures can significantly affect battery performance and lifespan. In this blog post, we will explore some expert tips and practical information to help you keep your electric bicycle battery in optimal condition during the winter season.
Storing the Battery in a Temperature-Controlled Environment:
Extreme cold can have a negative impact on the capacity and overall performance of electric bicycle batteries. It is crucial to store the battery in a dry, temperature-controlled environment whenever possible. The storage temperature should be maintained between 20°C and 25°C (68°F and 77°F) to ensure the best battery health.
Keeping the Battery Charged:
During winter, even if you don't use your electric bicycle frequently, it is essential to keep the battery charged. Commonly used lithium-ion batteries in electric bicycles self-discharge at a higher rate in colder temperatures.
During storage, the battery charge should be maintained between 30% and 60% to prevent deep discharge or overcharging. Using a smart charger that can automatically maintain the optimal charging level is recommended.
Minimize exposure to extremely cold environments during riding:
When riding in winter, take precautions to protect your electric bicycle battery from extreme cold. Lower temperatures can temporarily reduce the battery's capacity, affecting its range. Consider using neoprene covers to insulate the battery and provide some thermal protection. Additionally, avoid leaving your electric bicycle parked outdoors in freezing temperatures for extended periods.
Optimize battery usage and efficiency:
To maximize the performance of your electric bicycle battery during winter, take the following energy-saving measures:
A. Use pedal-assist mode: Pedal-assist mode is more efficient than relying solely on the throttle. It reduces the strain on the battery and extends the range.
B. Avoid frequent rapid acceleration: Sudden bursts of acceleration can deplete the battery more quickly. Gradual acceleration and maintaining a steady speed help conserve energy.
C. Plan your route wisely: Plan your rides to minimize steep inclines and strong headwinds as these factors increase the workload on the battery.
Regularly check battery voltage and capacity:
Monitoring the voltage and capacity of your electric bicycle battery is essential for understanding its health. Use a battery monitoring system or consult the electric bicycle manufacturer's guidelines to measure the battery's voltage and capacity regularly. If you notice a significant decrease in capacity or abnormal voltage readings, consider contacting professionals for further inspection.
Conclusion:
Properly maintaining your electric bicycle battery in winter is crucial for ensuring optimal performance and lifespan. By storing the battery in a temperature-controlled environment, keeping it charged, minimizing exposure to extreme cold, optimizing battery usage, and monitoring its voltage and capacity, you can enjoy reliable and efficient rides throughout the winter season. Remember, a well-maintained battery enhances your electric bicycle experience, allowing you to effortlessly ride through snowy landscapes.
An electric bicycle consists of two essential components: the motor and the battery. Both are crucial, and it is important to choose the right battery for your DIY customization. In this article, I will do my best to explain e-bike batteries in a simplified manner.
There are many factors to consider before purchasing a battery, and it's important not to make hasty decisions, as even lower-spec batteries can be costly.
I could write pages upon pages about modern batteries and their working principles, but I want to keep this article as simple as possible, focusing on selecting the right battery for your specific build.
Several variables need to be considered before buying a battery. I will list them below, and each one requires careful consideration:
For the purpose of this article, I will focus on the most popular voltages currently used:
Most road-legal e-bike kits use a 36V battery, while more powerful motors may require a 48V or even a 52V battery. When using high-performance electric bikes, the voltage can reach up to 72V or even higher.
For example, if you purchase a 250W mid-drive motor, you would need a 36V battery. If you opt for a 1000W BBSHD motor, you would need a 48V battery.
You need to decide where you want to mount the battery on your bicycle. The most popular location is the downtube in a diagonal position because it not only looks neat but also keeps the additional weight of the battery relatively centered and low, improving stability.
The Cube Target Pro mountain bike is powered by a Bafang BBS02 750W electric motor kit and a 52V battery.
Unfortunately, this may not apply to all bicycles and depends on the frame size and geometry. For many full-suspension mountain bikes, it can be challenging to mount the battery on the frame due to the rear suspension. Fortunately, there are now more compact battery packs available, but these packs have smaller outputs, typically around 36V 10.4Ah. Alternatively, you can mount the battery on the underside of the frame, but this may make it more susceptible to damage, and you need to check the clearance with the front tire when the suspension is fully compressed.
Frame-integrated batteries are also popular options for step-through frame bicycles or small frame bicycles. These types of batteries typically come with specific "double-layer" frames, which inevitably add weight to the rear of the bicycle.
Another important variable to consider is the Ah or "ampere-hour" rating of the battery. A battery with a capacity of 1 ampere-hour should be able to continuously provide a current of 1 ampere to the load for exactly 1 hour, or 2 amperes for 1/2 hour, or 1/3 ampere for 3 hours, and so on, before being fully discharged.
The capacity of a medium-sized battery is typically around 13Ah. When multiplied by the voltage, such as 36V x 13Ah = 468Wh, it gives the capacity in "watt-hours" (Wh). Watt-hours is a unit of electrical energy, equivalent to the power consumption of one watt over one hour. Therefore, a 36V 13Ah battery can effectively sustain 468 watt-hours.
How does this translate into measurable range? Assuming you are conservative with the power usage, you would spend approximately 20 watt-hours per mile of travel, giving you a range of 23.4 miles. This is based on the assumption of maintaining power consumption at that exact level throughout the duration.
Of course, in the real world, this scenario is unlikely as there are times when you may not need electric assistance at all, while other times you may heavily rely on it. For example, if you live in an area with long and steep hills, your power consumption per mile may exceed 20 watt-hours. If you reside in a fairly flat area, your consumption may be lower.
If you desire to achieve longer mileage, a 36V 17.5Ah battery would allow you to travel 31.5 miles at a constant power consumption of 20 watt-hours per mile. However, in real-world scenarios, I have reported ranges of 50-60 miles with such capacity batteries.
If you can only purchase a smaller battery, there are many ways to increase the battery range of an electric bike without spending any extra money.
Most electric bike batteries use standard 18650 lithium-ion cells produced by well-known manufacturers such as LG, Samsung, Panasonic, and Sanyo. In my opinion, opting for branded batteries is always wise as they tend to have longer lifespans and greater reliability compared to unbranded generic Chinese batteries. That being said, I have provided many battery packs using Chinese batteries without any issues. It all comes down to the price. Personally, I would spend a little more to purchase branded batteries as buying cheaper batteries might be a false economy.
Lithium batteries require careful handling. There are restrictions on their transportation, and it's not without good reason. The problem is that if they catch fire, they burn at very high temperatures and can cause severe burns or even death. Do not store them in areas exposed to extreme heat.
These batteries do not like extreme temperatures at either end. Their performance decreases once the temperature drops below zero, and most manufacturers set the minimum operating temperature at -20 degrees Celsius and the maximum at 45 degrees Celsius.
When the battery is new, it is generally recommended to run it through at least three full charge and discharge cycles to ensure the battery is fully balanced, although I have ample evidence to suggest that discharging the battery to at least 50% during normal use is sufficient for this period.
There is some evidence to suggest that always fully charging the battery can shorten its lifespan, and most of the time, charging it to 80% and only fully charging the battery once is more beneficial for long-term battery health over weeks.
This is a somewhat controversial topic, as a highly respected lithium battery expert told me that this is not the case. In fact, I had a customer who followed the above practice, and several months later, the maximum charging voltage dropped significantly, and the battery needed to be rebalanced.
If the battery is not used for several months, it is also essential to ensure that the battery has at least 80% charge. If the battery is left discharged for several months without use, the voltage in the battery may drop below the design minimum and could result in permanent damage. Additionally, it is not recommended to store the battery at its maximum capacity for more than a few days, as this is also detrimental to the long-term health of the battery.
All these battery packs use a Battery Management System (BMS), which is the brain of the battery. It is a small electronic circuit that prevents overcharging and over-discharging and regulates the overall amplifier output. A fully charged 36V battery has a voltage of approximately 42.2V, and the BMS typically shuts off the battery at around 29V. A fully charged 48V battery has a voltage of 54.4V and usually shuts off around 39V. This is crucial because over-discharging can permanently damage the battery's chemical composition.
This depends on several factors but will be influenced by the battery quality, voltage, Ah rating, and BMS. Most 36V 13Ah batteries have a continuous discharge rate between 15A-20A but may be able to provide higher output momentarily. This also depends on the type of motor controller being used. For example, the controller on a 1000W Bafang BBSHD can handle a continuous current of 30 amps.
A good mid-drive motor, such as Bafang or Tongsheng, utilizes the bike's gear ratio to transfer the power generated by the motor to the rear wheel. This results in higher efficiency and less battery energy consumption. On the other hand, large direct-drive hub motors cannot spin as fast, so they will consume more watt-hours per mile.
The weight of the rider also plays a significant role. A person weighing 100 kg riding a 250W electric bike at full power will consume more energy compared to a person weighing 75 kg.
If you only plan on using the bike for short trips of up to 20-30 miles, then a 36V 13Ah battery should be sufficient. The same applies to a 48V motor. However, if you plan on traveling or spending long periods in the saddle, it would be worthwhile to purchase a battery with a capacity of at least 36V 17.5Ah or even 20Ah.
The differences between lead-acid batteries and lithium-ion batteries on electric bicycles are quite apparent.
Lead-acid battery systems can be several hundred or thousand dollars cheaper than comparable lithium-ion batteries.
Currently, the price range for lithium-ion batteries is between $5,000 and $15,000 (including installation costs), and this range may vary depending on the size of the required system.
The purchase and installation costs of lead-acid batteries are generally cheaper than lithium-ion batteries.
The cost component of lithium-ion batteries is higher; however, the lifespan value of lithium-ion batteries offsets this impact.
The energy density of lead-acid batteries is much lower than that of lithium-ion batteries. Lithium-ion batteries have significantly higher energy density compared to lead-acid batteries.
Lithium-ion batteries can store more energy in the same physical space. Additionally, they can release more energy, providing power for a longer duration.
The discharge capacity of lead-acid batteries should not exceed around 50% as it can shorten the battery's lifespan.
Typically, lithium-ion batteries utilize 85% or more of their total capacity in a single cycle. Therefore, lithium-ion batteries have better effective capacity than lead-acid batteries.
The efficiency of lead-acid batteries ranges from 80% to 85%. These batteries charge slowly and have lower effective battery capacity.
Most lithium-ion batteries have an efficiency of 95% or higher, meaning that 95% or more of the energy collected in the lithium-ion battery can be utilized. These batteries charge quickly and have a larger effective capacity.
Lead-acid batteries are well-suited for large-scale stationary applications where space is abundant and energy demands are low. In terms of cost and size, lithium-ion batteries may be the ideal choice for electric bicycles.
Environmental Friendliness:
Lead is a carcinogenic and environmentally hazardous substance. Even lead-acid batteries contain dangerous compounds like sulfuric acid. Lithium-ion batteries are more environmentally friendly as lithium is a harmless substance.
For electric bicycles, lithium-ion (Li-ion) batteries are the best choice. While lead-acid batteries are still much cheaper, they are three times heavier than lithium-ion batteries.
Lithium-ion batteries are favored for their lightweight nature and suitability for long-distance travel. Compared to older battery technologies, lithium-ion batteries offer faster charging, longer range, and better power density, achieving longer battery life in lighter containers.
However, the five most critical variables to consider when choosing battery chemistry are specific energy, cost, lifespan, power, and safety.
With proper maintenance, the battery lifespan can range from 3 to 5 years. Even when not in use, lithium batteries on electric bicycles will gradually lose capacity and self-discharge.
Even if the connected electric bicycle doesn't require any power or remains unused, the lithium battery on the electric bicycle will lose the stored energy due to internal actions.
Excessive self-discharge can cause irreversible damage to the electric bicycle's battery. Therefore, it is recommended to actively utilize it.
Generally, a high-quality eBike battery may last between 3 and 5 years. Of course, this depends on various factors, including the type of battery, and how well you maintain it.
The major factors recommended for prolonging the e-bike’s battery life include the following:
Charge your battery completely for up to 4-7 hours before your first ride to extend its lifespan.
Use the original charger provided during the initial purchase with your e-bike; never mix and match chargers.
Do not wait until your e-bike battery is completely drained before charging.
Maintain your e-bike by charging it regularly and adequately.
Establish a charging station that is both dry and secure. Electrical gadgets should not be exposed to high humidity.
Learn your battery’s high and low voltage cut-off limitations.
Regularly clean around the battery connections and eliminate any corrosion.
Lithium batteries are the most prevalent battery in electric bikes nowadays.
Which is better, lead-acid batteries or lithium-ion batteries? In most cases, lithium-ion battery technology is superior to lead-acid battery technology due to its advantages in reliability and efficiency.
If the electric bicycle is not used frequently, the cheaper lead-acid battery may be preferred. According to recent research, the lifespan of lithium-ion batteries in electric bicycles is 45% longer than that of equivalent-rated lead-acid batteries.
