Are you facing e bike battery problems like the battery won’t charge, or the battery dies quickly? If you are having any battery problems, then you have come to the right place because, in this guide, we will mention all potential e bike battery problems and their solutions, so if you face any problem, you can fix it.
E Bike Battery Problems and their Solutions
Read the following electric bike problems and their ultimate solutions:
E-Bike Battery won’t charge
The most common problem in an electric bike battery is that it won’t charge even if you connected the charger correctly. There are many reasons why battery won’t charge; some of them are that your charger is damaged or you are not using original charger, sometimes your bike battery management system (BMS) is not working. BMS function is to monitor and control the discharging and charging of the battery. If your BMS is dead, then it won’t charge your electric bike battery, and sometimes you have a loose connection when you attached your battery to a charger, and loose connection will hinder the flow of current and battery will not charge properly.
Now make sure you are using the original charger, not other company chargers, and if you are using the wrong charger, then try using the original manufacturer charger if the problem is fixed then it was due to faulty charger. If the e-bike battery problem is still there, then you have a loose connection, so make sure the connection is complete while charging. If still facing charging problems then your BMS died, which is not allowing your charger to charge the battery, try replacing old BMS with a new one and check it is charging or not
The e bike battery has discharging issues
Another one of the so many e bike battery problems is that it starts discharging without even you are not using your bike and all the battery is drained without using it. The main reason for the draining issue is that your BMS is not working. BMS’s other primary function is to discharge when it is needed, BMS discharge when you are riding your bike, so if it discharges without any reason, then the problem is in BMS. Battery draining is the worst problem for electric bike owners because if you are far from home and run out of battery, then it will be a huge problem if there is no charging outlet nearby.
Fixing a discharging issue is easy; all you have to do is to replace your old BMS with a new one and your problem will be fixed. You can easily buy new BMS from a retail store.
Electric Bike Battery dies too quickly
Other common e-bike battery problems are that it dies too quickly after using for little time, even if you charge your battery to 100%, but it won’t last for long. The main reason for the battery not lasting for a long time is that your battery is old, and its charging life cycle is complete. The most battery life cycle is around 600 to 700, and when the life cycle is complete, its output will reduce and will not give you long-lasting performance.
Now first check if your charging life cycle is complete or not. One full battery charge is equal to one cycle, and if your battery has 600 life cycle and you have already charged you battery fully 600 times then your charging life cycle is complete, so you should buy a new battery. A new battery will cost you around 500 to 600 dollars, and you can purchase a new battery from an online store like Amazon, or you can buy from local retail stores easily.
Sometimes battery won’t work because it is dead, and a dead battery is the worst nightmare for electric bike owners; there are many reasons for a dead battery, it might be damaged due to overcharging or might be dead using the wrong charger. So if you have a dead battery, it won’t start your e-bike.
If you have a dead battery, there is still hope that you can revive it. I have seen many people saying that they have fixed their dead battery because sometimes the reason for a dead battery is small and fixable like it has some circuit problem or sometimes one cell is not working. If you have all the equipment and electric knowledge, then you can fix it yourself. Still, I recommend you take your dead battery to professionals and fix it for you. If your dead battery is revived, then it is right for you because it is a better option than buying a new one; a new battery will cost you around 600 dollars, which is a considerable amount.
How to protect the ebike battery from harm?
It is always better to keep your battery safe, so you don’t get any problem in the future, so below, I will tell you a few tips to protect your battery from harm.
Always keep your battery in a palace where the temperature is under 40-degree Celsius. Mostly, e-bike owners put their battery in a car garage, but the garage’s temperature is warmer, so it is better to keep it under a shed. Even batteries are waterproof, but still, you should keep your batteries away from water. If you are not cycling your e-bike for a long time, it is recommended to remove the battery from an electric bike and put in indoor and charge it once a month for maintenance. Always use original manufacturer charger, sometimes other company chargers will damage your battery and always buy good brand batteries like Panasonic or Honda; they will give you longer battery life.
