How Does e-Bike Battery Work?
Understanding how an e-bike battery works is crucial when exploring alternative charging options.
An e-bike battery consists of several cells, each with a positive and negative electrode. When the battery is charged, electrons flow from the negative electrode to the positive electrode, storing energy in the cells.
When the battery is discharged, the electrons flow in the opposite direction, creating an electric current that powers the e-bike motor.
To maintain the battery’s health and extend its lifespan, it is important to charge it regularly and avoid completely discharging it.
Additionally, it is important to ensure that any alternative charging method used does not cause overcharging or undercharging, as this can damage the battery and reduce its performance over time.
