In this article, we will not only tell how to reset ebike battery but we will also explain about the BMS of an e bike. To use your e bikes efficiently and your batteries with optimal performance and long battery life, you have to understand about BMS of an electric bike.
What is a BMS?
BMS is Battery Management System of an e bike which is present in your bike to ensure a consistent and uniform performance of each battery cell in the battery pack of the e bike. The work of BMS in an e bike is to maintain a harmonized and balanced operations across all cells instead of allowing individual variations in individual cells. All this is really important and crucial for achieving a reliable and uniform performance of an e bike’s motor.
What does BMS do?
Battery Management system in your e bike keeps your e bike’s battery health in check by constantly monitoring individual cell temperature, voltage and overall charging state. Doing this BMS prevents the overcharging or deep discharging of the battery, which can cause serious damage to the battery cells.
It also balances the individual cells voltage inside the battery which prevents issues like uneven charging and reduced battery capacity. This balancing of cell voltages extends the battery’s life and also maximize it’s overall performance.
BMS also protects the battery from overheating, overcurrent, short circuits and many other electrical faults by acting as a safeguard for the battery which poses a safety risk and can also permanently damage the battery.
How to reset ebike battery? Step-by-step guide
Resetting the Battery Management System or BMS of your e bike may sound intimidating but believe me it is not that complicated. And, it also fix many issues of your e bike such as reduced range, charging problems, and reduced capacity and error codes.
Here’s a step-by step guide on resetting your ebike battery:
Step 1: Consult your User Manual
Before doing anything, firstly just check your e bike’s user manual for any instructions or special precautions given in that for resetting the battery of your e bike as different e bikes have different procedures of resetting its battery.
If you don’t find the user manual then, find any specific instructions given on the manufacturer’s website of your e bike’s model.
Step 2: Power down your e-bike
Make sure your e bike is completely turned off and not connected to the charger. So that all the electrical components of the bike gets in a stable condition before we reset it.
Step 3: Remove and disconnect the battery
If possible, remove the battery carefully from your e bike. Depending on your e bike, you can either remove the battery from its mount or you can only unplug any connectors, ensuring the battery is completely isolated or disconnected from the e bike’s electrical system.
Step 4: Drain battery residual power
Now, if your e bike’s battery have a power button on it then, press that power button so that the residual power stored in the battery can get drained out. Some e bike’s models might need this step to successfully reset their battery.
Step 5: Wait for some time
Now, check your user manual and see what time is specific in it (usually between 10-30 minutes) for the battery to fully rest and help the battery’s internal components to reset properly.
Step 6: Re-connect the battery
After giving rest to the battery, reconnect the battery to your e bike, ensuring the battery is securely locked in place and all connectors are attached properly.
Step 7: Turn on the bike
Turn on your e bike now and check whether it is operating correctly and all the issues are resolved after the reset. But, if the problem still persists then, perform the reset again and repeat all the steps correctly or consult any professional assistance.
Step 8: Perform a full Battery Calibration (if needed)
A full battery calibration is recommended if after resetting the battery, the problem or issue still unresolved. To perform this calibration, firstly you have to charge the battery to its full capacity then, drain the battery power completely by riding it or by any other method. After the battery gets fully drained then recharge it again and then, use the battery. Usually after the calibration the battery starts working properly.
If you aren’t confident or this procedure looks intimidating to you then, you can also look for any specific instructions regarding this in your e bike’s user manual or can take any professional support.
Conclusion
Resetting your e bike battery is a very simple and easy way to fix different minor issues such as charging problems, performance issues. If this process looks intimidating or very complicated to you then, it is recommended to take any professional assistance. By understanding how to reset your ebike battery, you can easily maintain your e bike’s performance and also can extend the longevity of your e bike and its battery.
