Buying an electric bike is a considerable investment, so it’s imperative you take good care of it. Among all components of your e-bike, the battery is the most expensive one (so it obviously needs proper care). Taking care of your electric bike battery not just increases its life, but also gives you a longer range on every charge. In this blog, we will discuss how you can maximize your e-bike’s battery.

Life on an Electric Bike Battery

Most electric bikes that are available on market today come with batteries that have a life of 800-1000 cycles. The cycles, or charge cycles, means when you fully charge a battery from 0 to 100%. In other words, it means a battery that has a rated life of 800 charge cycles would work effectively only for that much period. After that, it would still be working but it might not be delivering the same range as before.

To put that into perspective, let us assume your ebike can give you a range of 25 miles on a single charge. Now, for most people, this range is sufficient for a day… that’s to take them to their work and back. Considering that you travel 25 miles everyday, you’ll be needing to charge your battery everyday, and will therefore be consuming one charge cycle everyday.

Provided that you use and charge your ebike everyday, your battery will maintain effective functioning for 800 days, that’s more than 2 years. Even after that, a good quality battery won’t lose much of its capacity to hold charge… and will still give you adequate range. 

Also, you must note that if you recharge a battery that has 50% charge remaining in it, that will count as a half cycle, and not a full cycle. This means if you half charge a battery rated for 800 cycles everyday, it will be good for 1600 trips. That’s why the batteries that have a higher charge capacity (higher Ah) tend to last longer.

Besides the charge capacity, the Battery Management System is another important factor that decides the life of an electric bike battery. Modern batteries today come with an advanced BMS (Battery Management System) that protects them from short-circuit, over-heat, high-temperature, over-charge, over-discharge, and over-current so as to ensure longevity. If you can take care of your battery (and its BMS), you can significantly enhance its life.  

How to Maximize Electric Bike Battery Life?

Let us now discuss some pretty useful tips that can help maximize your electric bike battery life. In addition to doing that, these tips will also help you get more mileage from your battery for every trip that you will undertake.

Use safe practices while charging

The first and foremost thing to do is to keep your battery safe from all kinds of malpractices while charging. For instance, if you are charging your battery outside the bike frame (in case of removable battery ebikes like the Engwe Engine Pro), make sure no  flammable substance is present near your battery or your charger. 

Likewise, if you’re charging your electric bike battery inside the bike, make sure that your ignition lock is switched off and that your motor isn’t on. Some e-bikes have a separate battery switch, so look out for that and turn it off.

Follow ‘shallow’ charges & discharges

One common misconception about lithium-ion batteries is that they perform well if they are charged to 100%. Well, this is not just wrong… but counter-productive. Doing so can, in fact, reduce the lifespan of your battery. You should never overcharge your battery, and should plug it out as soon as it is full. 

Likewise, you don’t have to let your battery drain completely before recharging it again. You have to follow the “shallow” approach in this regard as well. As a matter of fact, many battery manufacturers recommend users to charge their batteries as soon as possible. Samsung, for instance, recommends that it should never be drained below 20%.

Charge your battery regularly

In addition to following the “shallow” approach in charging and discharging your battery, we highly recommend you charge your electric bike battery after every ride. At this point, it should not come as a surprise to you that Lithium-ion batteries work efficiently if you charge and discharge them regularly. 

In case you won’t be using your e-bike for quite some time or if you want to store it for any reason, make sure to never store it while your battery is empty. You should store the battery with at least 50% of charge. Moreover, for storage for an extended period of time, you should recharge your battery after every couple of months.

Avoid experimentation of any kind

Don’t be surprised. Many people do, in fact, conduct experiments of various kinds on their bike batteries. Always keep in mind that your electric bike battery is compatible with your e-bike alone, and that you should never operate any other device from your battery.

Likewise, you should only use the manufacturer-provided charger that comes with the battery… as using a different/ non-compatible charger can damage your battery besides also voiding the warranty for many brands. In case your charger gets damaged or misplaced, you should get another charger from the brand.

Avoid extreme temperatures

All lithium-ion batteries perform optimally at a certain temperature range, usually room temperature. If the temperature is too high or too low, the battery performance might be impacted. When charging, make sure you charge your electric bike battery at room temperature. 

High temperature, in particular, is extremely dangerous for the health of your electric bike battery, as it can cause your battery cells to degrade over time. This is why you must never leave your electric bike in any kind of hot environment or in direct sunlight. Likewise, if you have come from outside and it’s cold out there, wait till the battery gets to room temperature before charging it.

Proper storage

If, for any reason, you have to store your electric bike battery for a long time period, you might consider storing it. While doing so, you should not only keep the charge to around 50%… but you must also make sure the storage place is neither too cold nor too hot. Always store your battery at room temperature, and also make sure the battery remains safe from water or any other weather element throughout the time it is stored.

Responsible riding practices

As we explained before, the lifetime of your electric bike battery depends on how much use you get out of it. A battery rated at 800 cycles will last for 2 years if you drain and charge it everyday… but if you somehow increase the range you get for every charge, you won’t need to charge your battery everyday. 

Consequently, less charge cycles will be consumed, and you will have a longer battery life. With that said, here are some important tips that can help you get more mileage for every charge.

Don’t Overload

The more weight you carry on your bike, the more strain it will cause to your motor and battery. As a result, the battery drains faster. This is especially important when you’re riding a city e-bike like the Engwe T14.

Gentle Riding

Always try to ride at a constant speed. This will significantly boost your range, as suddenly increasing or decreasing your speed takes a lot of energy from your powertrain. So always try to ride smoothly. 

Wisely Use Pedal Assist 

All ebikes today come with multiple pedal-assist levels so that you can get any amount of assistance as you require, depending on the terrain and your ride conditions. The higher levels of pedal-assist make the motor do most of the work for you… and therefore more charge is depleted when you ride at them. Conversely, riding at lower pedal assist levels will significantly increase your range.

Avoid High Speeds

If you consistently ride at a high speed, your battery will drain much faster than it will at lower speeds. It’s always best to go for a moderate speed, that’s also safe with respect to the road you’re riding, for best results.

Avoid Rough Terrain

When you ride on any kind of rough terrain, you constantly need to vary your speed and power output based on the track conditions. For instance, when riding uphill, you will be spending more power. So, when possible, choose a flat and smooth path. This can increase your range when you’re riding a fat tire ebike like the Engwe M20.

Use Gears

Using gears can bring a lot of efficiency in your ride. When you’re going uphill, riding in lower gears can amplify your motor output, giving you a mechanical advantage and resulting in an efficient ride. Likewise, when going downhills, shifting to higher gears conserves the energy by letting the motor rotate in its ideal RPM range. 

Maintain Tire Pressure

Maintaining the correct tire pressure can also conserve your battery charge and give you a longer range. This happens because the uninflated tires are flatter, which increases rolling resistance. As a result, your motor (and the battery) has to do a lot of work. Tires with proper air pressure face less rolling resistance, which is why you experience a better range.
