Resetting a Lithium Battery BMS might sound like a daunting task, but it is actually quite simple. The first step is to disconnect the battery from any power source and remove it from its housing. Next, locate the BMS reset button or switch on the battery management system. Press and hold this button for 10-15 seconds.
Steps on How to Reset Battery Management System Using Software/Application: Connect the BMS with a computer or smartphone using a cable or Bluetooth. Open the factory default app to monitor or reset the BMS. Enter the “Advanced Settings” or “Device Control” menu.
Finally, initiate the BMS reset by plugging the battery charger into the adapter. Once the charger’s red light indicates that the battery is charging, hold the wires in place for at least 15 seconds to ensure a successful BMS reset. Also Read: Can E-Bike Fat Tires be Offset by a Fat Battery?
Over time, a BMS battery may develop issues that can negatively affect its performance, such as capacity loss and reduced lifespan. Resetting the BMS battery can help clear any errors and improve its overall performance. Here's how to reset your BMS battery:
Resetting the BMS may change some statuses such as battery SoC, error log, or temperature calibration. Therefore, if the reset process is not done properly, it can cause several things such as incorrect battery capacity readings, undetected errors, or even imbalances between cells.
One common sign that indicates the need for a BMS battery reset is decreased battery performance. If you notice that your batteries are not holding their charge as they used to or if they are draining more quickly than usual, it could be an indication that the BMS needs to be reset. Another telltale sign is irregular charging patterns.
