E-bikes are convenient and immensely beneficial to the users. And it’s not surprising that they’re rising in fame across the globe. An e-bike is costly to replace because of its expensive parts. And if you want long-term returns on your investment, you must take great care of your electric bike, including its primary component: the battery.
Charging an electric bike isn’t as straightforward as pumping the gas. You might be swarmed with several queries about charging an e-bike battery and optimizing its useful life.
If you’re confused about keeping your e-bike on charge overnight and whether that’s safe or hazardous for the vehicle, you’re not the only one.
Read on to discover answers to your questions about the possibility of overcharging your e-bike battery and charging the e-bike overnight.
The simple and basic answer would be yes and no, depending on a few factors. Primarily, your e-bike model matters quite a lot.
You can charge Older electric bikes more than 100% because they don’t have the advanced technology to stop the charging automatically.
That means you must resort to other alternatives to ensure you don’t overcharge an e-bike battery. Setting the alarm on your phone or getting a smart plug are the two most practical solutions that come in handy. If you can’t change the battery, change the charger. Simple as that.
On the other hand, the recent e-bike models can’t be overcharged because they automatically stop charging once the battery hits 100%.
However, if you don’t disconnect the charger and leave it attached even after the battery is fully charged can deteriorate its performance.
And if you continue doing this, the e-bike’s battery will start depreciating and continue discharging even when you’re not using it.
Overcharging an e-bike’s battery means you’re reducing the battery life and increasing the possibility of overheated batteries.
Overheating can damage the battery beyond repair till you have no other option but to replace it. And here’s a head’s up: e-bike batteries can cause quite a dent in your savings!
If you own and use modern electric bikes, you’re slightly safer and benefit from their advanced charging option. It avoids overcharging and overheating.
However, as mentioned above, it can still adversely affect the battery’s lifespan, slowly yet steadily.
Unfortunately, overcharging an e-bike battery doesn’t benefit you or your electric bike in any way. If you try to charge your e-bike for more than 100%, it only results in adverse consequences, as listed above.
Therefore, the maximum you must charge your electric bike is 100%- that too on rare occasions when you have to use the bike to cover longer distances.
Imagine entering your house after a long and tiresome day at work, parking the e-bike in the garage, and having no motivation to come back later and unplug the e-bike.
But you’re wry about leaving the e-bike on charge overnight and if that’s a safe step to take or not. You’d be relieved to know that you can charge your electric bike battery overnight, safe and sound. There’s always a but, though.
Overnight charging is alright if you’re taking care of your e-bike battery and charger. Moreover, it again depends on how modern your e-bike is.
Reputable and premium brands, including Shimano, Yamaha, Bosch, and Giant, offer Battery Management Systems in their e-bikes. They stop the e-bike battery from getting overcharged and damaging its lifespan.
However, if your e-bike doesn’t have this feature, you shouldn’t leave it on charge overnight when you know there are high chances of battery overcharge.
In addition, if your e-bike has a lithium-ion battery and you leave it on charge overnight, it can overheat, burst into flames, and even start horrific fires. Then again, if you’ve installed a newer battery, you don’t need to worry about fire anymore.
The question arises: how to charge your e-bike overnight without jeopardizing its battery life? Continue reading to find some of the most valuable tips.
Buying a new electric bike is, without a doubt, an exhilarating experience. But a little more patience can ensure your eagerness and maintain your bike’s life.
Ideally, you must allow the e-bike battery to charge for almost 12 hours or until it’s at 100% and then go out for your first ride.
The extensive time frame allows development and builds the flow of electric current through the bike.
In addition, these twelve hours are considered to be the conditioning hours for the battery to start working and delivering smooth rides.
While overcharging can affect the battery performance, keeping your e-bike battery to 100% every time isn’t ideal. And it doesn’t matter if you have a modern or older model of e-bikes.
Regardless, you must always try to charge your e-bike battery between 80% to 90%. Even the electric bike manufacturers suggest keeping your e-bike battery charged anywhere between 20% to somewhere near 85% to prolong its useful life.
You must charge your electric bike using the charger you got with the e-bike. This charger contains the same amps and voltage that your e-bike battery requires. And so, that ensures safe charging without harming the battery’s life.
You typically get the charger when you buy the e-bike or the battery. But if you don’t, for some reason, you must check the amps and voltage when you’re purchasing the charger.
For instance, if your e-bike has a 48-volt battery with 5 amps, you can’t attach it to a charger meant for a 36-volt battery with 2 amps.
Moreover, if other residents in your house own electric bikes, be sure to label the chargers to avoid mix-ups and battery damages.
As you plug in your e-bike, you must always turn off the power of the motor and bike. That guarantees quicker charging and lasting results. It even sustains the lifespan of your e-bike battery.
If you have an e-bike that offers a removable battery, you must detach it from the vehicle before turning the charger on.
However, if you don’t have a portable battery, you can always turn its power off before plugging on the charging station.
While you can usually keep your e-bike charged to around 80%, charging it to 100% once in a while doesn’t hurt. If you’ve got a long ride planned the next day, it’s beneficial to charge your electric bike completely.
After all, you don’t want to spoil your bike ride if the battery runs out in the middle of the trip and you can’t charge it anytime soon.
Therefore, you can ensure a smooth ride by charging the e-bike overnight till it reaches 100%. You can even install a smart plug or power bar to control the charging through your mobile.
You can even use the app for setting a timer and turning the charger off after the required charging time of the battery.
Charging electric bikes in intense and severe climatic conditions can harm the bike’s overall performance and useful life. That’s one reason why overheating can cause the battery life to diminish instantly.
So, you must check and maintain the temperature of the batter when you’re using the e-bike and when you’re charging it.
E-bikes work and charge the best in moderate temperatures, which is why you must keep the battery somewhere that’s not too hot or freezing.
Preferably, the temperature when charging your e-bike battery should be around 50 to 70 degrees Fahrenheit.
Don’t’s Of Charging An E-bike
Now, what must e-bike users avoid when charging their electric bikes overnight and in general? Here are some of the most crucial errors that can damage e-bike batteries.
It’s alright if you’re not using your e-bike every day. Maybe it’s too cold out there, or you’re busy with other chores. You might not be in the mood for bike rides.
And if you’re not using the e-bike, you can remove the battery and store it somewhere with a moderate climate. But before that, you must charge the electric bike partially.
You don’t need to charge the battery to 80%; anywhere between 40% to 60% works. But storing an empty and discharged battery and leaving it uncharged for several days can damage its performance.
And you certainly don’t want to spend a significant amount in replacing the battery, anyways.
Overcharging your electric bike once by mistake might not cause lasting damages. But following the same pattern continuously can be hazardous.
Overcharging e-bike batteries can reduce their capacity, and this inadequate charging cycle can eventually result in significant performance issues.
Even if you have modern e-bikes with smart charging, you must avoid charging the batteries to 100% and take the plug off after the completion.
Some batteries, like the lithium-ion ones, are well-renowned for their extended life, but here’s a catch. They remain working even better when you charge them regularly.
Firstly, you must never let the battery discharge to 0%, and then, you must ensure that the e-bike battery remains between 30% to 70% even when you’re not using it.
30% is borderline, so it’s better to plug the e-bike as soon as you see the charging falling to 32% or 31%. It’s best to avoid using the e-bike even when it’s 20% to 25% charged to prevent further performance and lifespan problems.
Buying an electric bike isn’t the only milestone you must achieve. Instead, you must compile research and prepare effective charging routines to prolong its battery’s useful life.
One thing is for sure; you must never overcharge an e-bike battery. And consequently, you shouldn’t leave your e-bike on charge overnight because that increases the risks of the battery overcharging and overheating.
If you buy one of the recent electric bikes, you’ve got your worries solved for you because the advanced charger prevents overcharging. Even then, you must remove the plug from the electric bike to maintain its performance for even longer.
If you have one of the previous models, you can set alarms on your phone or use a smart plug to turn off the charging once the bike is charged.
Apart from that, several charging strategies work for all e-bike models. Using the right and compatible charger and charging the e-bike battery in moderate temperatures are a few helpful practices.
Moreover, charging the e-bike regularly and keeping the battery charged when stored can further extend the battery lifespan. Ultimately, you want your e-bike to remain useful for a long time. And proper maintenance and charging of e-bike batteries is one crucial element that can ensure that.
