At ChamRider, everyone shares the core belief in educating customers about the potential hazards and the importance of taking preventive measures to ensure their safety.






This article aims to provide you with a useful guide. Therefore, we will discuss tips for safe charging and storing of lithium-ion batteries, as well as measures to take in case of emergencies.



How to Safely Charge an Electric Bicycle Battery


Most reported battery fires occur during the battery charging process. Therefore, consumers must be extra cautious when charging. Here are some tips regarding the correct charging process:



Always use the charger recommended by the manufacturer; if you purchase an aftermarket charger, ensure that it has UL certification and specifications identical to the original charger. Using a fast charger for non-fast-chargeable batteries can be dangerous.

Avoid placing the battery near heat sources such as heaters. High temperatures can damage lithium-ion batteries and lead to thermal runaway incidents.

Do not place the charger or battery on or near flammable materials like wooden furniture or building structures. Always try to place the charger and battery on a fire-resistant surface or space.

Always keep the battery within sight while charging. As an additional precaution, place a smoke alarm near the battery.

In the event of a fire, the initial few seconds are crucial as you still have a chance to extinguish it before it becomes uncontrollable; therefore, prompt response is essential.

Turn off the battery while charging.

It is normal for the charger to become warm during the charging process, but the battery should never become hot (warm to the touch). If you notice the battery becoming hot, disconnect it.

Avoid charging in temperatures below zero degrees as this can cause dendrite growth on lithium-ion batteries, leading to short circuits and fire incidents.

Charge in a well-ventilated area.

Do not leave the battery charging overnight.



Proper Storage of Lithium-Ion Batteries


The lithium-ion battery of your electric bicycle requires proper storage, and you can take some measures to ensure appropriate storage.



When storing the battery for an extended period, charge it to around 60%.

Avoid storing it in extreme temperatures or high humidity.

Do not use damaged batteries that are dropped, punctured, squeezed, or otherwise compromised.

If a lithium-ion battery catches fire, use a fire extinguisher to put it out (be cautious as such fires produce toxic smoke).

Avoid extinguishing lithium-ion battery fires with water, although it can be used to extinguish the fire, a report by the U.S. Department of Energy found that it requires excessive amounts of water.

Do not store batteries or charge them near a single point of exit.



Safe Use of Lithium-Ion Batteries
If the battery starts smoking, making unusual noises, or shows signs of melting, stop using it immediately and place the battery in a safe location.

If you notice drastic changes in voltage/performance, discontinue using the battery.

If you immerse the battery pack/bicycle in water, have it professionally inspected before using it again (moisture inside the battery pack indicates water has entered and may cause a short circuit).

Always use the battery with the product it comes with; do not use it for any other purposes.






Emergency Response Measures


For any electric bicycle owner, following the tips mentioned earlier can reduce the likelihood of emergencies. However, accidents can still happen. Therefore, it is important to familiarize yourself with measures to ensure the safety of yourself, loved ones, or anyone around you.



In general, when a lithium-ion battery catches fire, you can take the following three steps:



Use a fire extinguisher:

Depending on the size and type of the battery, there are several methods to extinguish a lithium-ion battery fire. You need to react quickly and prevent the fire from spreading.

Since fires caused by lithium-ion batteries are classified as Class B fires, you should choose a standard ABC or dry chemical fire extinguisher. The Class B classification is intended for distinguishing flammable liquids. As lithium-ion batteries contain liquid electrolytes, they fall under this category.



When burning, toxic liquid acts as a conduit for the fire, aiding in its rapid spread.



You can use the fire extinguisher to spray the flames until the fire is extinguished. The steps are as follows:



Pull out the safety pin to enable the use of the fire extinguisher.

Aim the nozzle at the base of the fire.

Squeeze the handle firmly.

To ensure the flames are completely extinguished, sweep the nozzle back and forth at the base of the fire.



Take the battery outside the building:

If you suspect any issues with the battery, such as excessive heat, liquid leakage, or unusual noises, you should place it in a safe, open outdoor space and wait for the battery to return to normal. Note that you should not attempt to handle a battery that is on fire or leaking, as it may pose a danger to you.

If the battery catches fire, wait for all the batteries to burn out, and then attempt to extinguish the fire.



Call the fire department:

Fires caused by lithium-ion batteries fall under the category of thermal runaway incidents. Subsequently, a fire involving an electric bicycle battery can present multiple hazards, such as toxic smoke, flames, and metal projectiles. After taking the necessary measures mentioned above, if you are unable to control the fire, contact the nearest fire department in your area.

Assess the severity of the situation and avoid approaching a burning battery. If you are not comfortable handling the fire, wait for the firefighters to arrive.

Introduction


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.



Choosing the Right Battery


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.



Battery Placement


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.





Battery Range


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.


Battery Maintenance


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.



Charging


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.




Continuous Current


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.



Other Factors to Consider


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.



Conclusion


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 speed at which the electric bike system disconnects and your riding style are crucial for battery performance. Almost all major bicycle manufacturers now offer a range of road and off-road electric bikes.

From cargo commuting e-bikes to sleek carbon fiber electric road bikes that are almost indistinguishable from non-motorized bicycles, electric bikes have evolved from novelty to practicality in the cycling world.



Anyone who has invested in battery-powered consumer electronics can attest to the noticeable decline in battery performance over time. Therefore, for anyone considering purchasing an electric bike and existing owners alike, e-bike battery maintenance is an important consideration.



The best electric bikes

The best electric road bikes

The best commuting electric bikes



With the rapid pace of development, some potential electric bike owners are concerned that the premium they pay today will be frustratingly outdated in a few months. This is not entirely accurate and largely depends on your usage.



Take the electric bike motor, for example. Mid-drive motors come in two rated output powers: 250W and 500W. More powerful motors may be enticing, but they also consume more battery energy. For regular commuting, a 500W motor is almost entirely unnecessary.



As more research and development resources are poured into the electric bike market, mid-drive motors may become more efficient or lighter, but riders don't necessarily need greater output power. The key is finding the right balance between power and efficiency based on your specific riding needs.



What you should consider is battery technology and how the usage of an electric bike affects battery life.





Learning from the lessons of other digital devices


Battery suppliers in the electric bike market have chosen lithium-ion as the standardized chemistry. This battery composition has been validated in consumer electronics and automotive industries. Therefore, there is a wealth of user data available regarding the health of lithium-ion batteries.



The motor of your electric bike will last a long time, with fewer moving parts prone to damage or heavy maintenance. Where performance may decline over time is in the battery pack.





Most smartphone or laptop users have experienced battery degradation over time. However, the loss of energy capacity can be mitigated. The most crucial impact on the health of electric bike batteries is the frequency of charging from very low energy levels.



If you frequently drain the battery to almost empty in most rides, the likelihood of significant degradation is very real. Ideally, you want to minimize the time spent at zero energy consumption and at 100% energy consumption.



Most electric bikes come with three-mode configurations, roughly divided into thirds. The lowest pedal-assist mode uses one-third of the available motor power, the middle setting uses two-thirds, and the third setting provides full power.

By default, using the eco mode, you should complete your electric bike rides with the maximum battery capacity possible.



Use it sparingly as needed


Limiting the depth of discharge is the most important way to maintain the health of electric bike batteries.



While we all occasionally enjoy maximum motor assistance, it is quite unnecessary, especially considering the lower limits imposed on electric bike systems in the EU/UK, which are set at 25 km/h.


The only time you should use the full power of the electric bike is when conquering the steepest slopes during challenging climbs.



By judiciously using only the battery capacity you need and not excessively consuming all the extra watts, you will enjoy better and more stable battery health over time.



The electric bike motor also prefers a consistent cadence, preferably in the range of around 80 RPM. To achieve the best match between your input and the motor's output, it is better to ride with higher cadence and lower gears.



If you frequently ride your electric bike and fully deplete the battery, you may consider models with larger battery capacity. Alternatively, you can choose plug-in range extenders to balance the overall load of the electric bike's energy system.







Rethinking the "free" speed


Different countries and regions have different regulations regarding the speed and specifications of electric bikes.



In the United States, the maximum power limit for electric bike motors goes up to 750W and disengages assistance at speeds of 32 km/h. Europe and the UK have adopted stricter definitions, with a power output limit of 250W for electric bikes used on roads, disengaging electric assistance at 25 km/h.



As a result, electric bike riders in the EU and the UK generally experience less battery degradation due to the configuration of their bikes. By using more conservative pedal-assist software to manage their energy usage, electric bikes in the EU/UK theoretically operate more efficiently than similar products in the US market.



Commuting and active transportation electric bikes were never designed to be speed machines. The value of these pedal-assist bikes lies in alleviating the challenges of long-distance commuting along hilly routes or reducing the pain of riding against the wind on the way back home in the afternoon.



Electric bikes are most useful when enhancing the rider's power on steep climbs or against headwinds. In both cases, speed is low. Active commuters don't need to climb steep hills at 40 km/h.



For electric bike enthusiasts in the EU and the UK, the more conservative assist setting of 7 km/h for mid-drive motors can provide an excellent ownership experience and contribute to healthier long-term battery health.

Battery Management System (BMS) is a technology specifically designed to monitor battery packs, which are organized electrically in an x-by-y matrix configuration to achieve desired voltage and current ranges for expected load scenarios.





The supervision provided by BMS typically includes:



1. Monitoring the batteries

2. Providing battery protection

3. Estimating the operational state of the batteries

4. Continuously optimizing battery performance

5. Reporting operational status to external devices



The overall goal of BMS is to optimize battery performance through intelligent management and protection, thereby extending battery life.
