    The Engineer's Guide to e-bike Power Systems: Voltage, Wattage, and Efficiency
    As an engineer, you know that power is everything. And when it comes to e-bikes, that power comes from the battery. But what exactly is the difference between voltage, wattage, and efficiency when it comes to e-bike power systems? Here is your guide to understanding all things e-bike power.

    Voltage

    The voltage of an e-bike battery is the amount of electrical potential energy that is stored in the battery. This is measured in volts (V). The higher the voltage of the battery, the more power it can provide to the motor.

    Wattage

    The wattage of an e-bike battery is the amount of power that the battery can provide to the motor. This is measured in watts (W). The higher the wattage of the battery, the more power it can provide to the motor.

    Efficiency

    The efficiency of an e-bike power system is the percentage of power that is converted into usable energy by the motor. This is measured in percentage (%) terms. The higher the efficiency of the system, the more power is available to the motor.

    Now that you know the basics of voltage, wattage, and efficiency, let's take a closer look at how these factors affect the performance of an e-bike.

    Voltage

    The voltage of an e-bike battery is the most important factor in determining the power output of the motor. The higher the voltage of the battery, the more power it can provide to the motor. However, voltage is not the only factor that determines the power output of the motor. The wattage of the battery also plays a role.

    Wattage

    The wattage of an e-bike battery is the amount of power that the battery can provide to the motor. This is measured in watts (W). The higher the wattage of the battery, the more power it can provide to the motor. However, wattage is not the only factor that determines the power output of the motor. The efficiency of the power system also plays a role.

    Efficiency

    The efficiency of an e-bike power system is the percentage of power that is converted into usable energy by the motor. This is measured in percentage (%) terms. The higher the efficiency of the system, the more power is available to the motor.

    Now that you know the basics of voltage, wattage, and efficiency, you can start to understand how these factors affect the performance of an e-bike.
