What to Do When an Electric Car Doesn't Move When Accelerating?

When an electric car has power but doesn't move upon acceleration, the first step is to check the battery. Common specifications in the market include 24V, 36V, 48V, 60V, and 72V voltages. You should test whether the battery's output voltage is normal. If the voltage is too low, it is likely a battery issue, and the battery should be replaced promptly. Next, check whether the electric car's controller is functioning properly, as improper operation can easily cause a short circuit in the controller's wiring. Below are some related explanations: Common faults in electric cars: The first type of fault involves normal battery performance, meaning no replacement is needed. Corresponding faults include a single cell being too low or too high. If a single cell is too low, that cell's voltage will be the first to reach the discharge cutoff voltage during driving, reducing the actual capacity of the battery pack. In this case, the single cell should be recharged. If a single cell is too high, it will be the first to reach the charging cutoff voltage at the end of the charging process, affecting the charging capacity. In this case, the single cell should be discharged separately.

Here's my experience: first do three things - take out your phone to record a video of the instrument cluster and send it to after-sales service, while simultaneously pressing the steering wheel voice button to call customer service. If there's sufficient battery, try switching to sport mode or manually turning off one-pedal mode. There was one instance where the regenerative braking system malfunctioned and locked the vehicle. Also, listen carefully for any buzzing sound from the motor - if there's sound but no movement, it might be gear slippage in the reducer. Nowadays, new cars all have remote diagnostic functions; just click "Vehicle Health Check" in the mobile app to get an immediate report. If you really encounter this situation, don't panic. Especially in winter, check if the charging port has ice buildup - frost on metal terminals can cause high-voltage interlock failure, just use a hair dryer to warm it up.
