What are the reasons for an electric vehicle moving slowly despite having power?

[LaPreston]

Electric vehicles moving slowly is primarily attributed to factors such as the battery, charger, drive motor, wiring, and load. Below are the detailed reasons for an electric vehicle moving slowly: 1. Battery: If the battery is old, it may not fully charge each time, leading to insufficient power, which naturally makes the electric vehicle seem power-consuming and unable to move quickly. 2. Charger: If the charger is aging or has internal faults, each charging session may not provide enough voltage, or the protection circuit may malfunction, cutting off the input voltage before the battery is fully charged. This results in insufficient battery power and affects normal usage. 3. Motor: If the motor is old, with severely worn carbon brushes or poorly lubricated bearings, it can consume a significant amount of electrical energy while delivering insufficient mechanical energy. 4. Wiring: If the wiring is old and worn, with poor insulation or oxidized circuit connections, the contact resistance increases, causing a voltage drop phenomenon. The voltage becomes insufficient to drive the motor normally, leading to wasted electrical energy.
