What Does Under-Voltage Mean for an Electric Bike?

[VeraDella]

Under-voltage in an electric bike means the battery power is insufficient. When the battery voltage drops below the operating threshold of the controller and requires recharging, the system will display an "under-voltage" status. This is a protective mechanism designed to prevent over-discharge of the battery. Typically, electric bikes are equipped with protection circuits to avoid excessive battery discharge. Below are specific details on related aspects: 1. For all electrical equipment, there is a rated voltage, but in practice, it cannot be guaranteed to operate exactly at the rated voltage. Instead, it operates within a range around the rated voltage, generally within ±15%. 2. To protect electrical equipment and ensure process quality, if the voltage falls below -15% of the rated voltage, it is considered "under-voltage." 3. When the operating voltage drops below this threshold, the protection mechanism activates and cuts off the power supply. 4. Conversely, if the voltage exceeds +15% of the rated voltage, it is considered "over-voltage," and the protection mechanism also activates to cut off the power supply.
