What to Do When an Electric Vehicle Has Power but Doesn't Move When Accelerating?

When an electric vehicle has power but doesn't move when accelerating, the first step is to check the battery. Common specifications on the market include 24V, 36V, 48V, 60V, and 72V. You should test whether the battery's output voltage is normal. If the voltage is too low, it is likely a battery issue, and it should be replaced promptly. Check whether the electric vehicle's controller is functioning properly, as improper operation can easily cause a short circuit in the controller's wiring. The electric motor is a key component of the vehicle; if there is a problem, the electric vehicle will not operate normally. Additionally, poor contact in the motor's carbon brushes can also cause the vehicle to fail to start. Electric vehicles, also known as electric-driven vehicles, are divided into AC electric vehicles and DC electric vehicles.

When the electric vehicle shows it has power but doesn't move when pressing the accelerator pedal, I immediately find a safe place to stop to avoid danger in the middle of the road. This situation is commonly caused by a faulty throttle sensor or aging wiring that prevents signal transmission, so the controller can't receive commands to direct the motor to rotate. Another possibility is that the brakes are stuck, and the safety mechanism locks the vehicle to prevent movement, so I try pressing the brakes back and forth to reset them. Checking the fuses is crucial—replacing them with new ones is inexpensive and easy if they're blown. If that doesn't work, it's best to push the vehicle to a repair shop and have a technician use equipment to check if the controller module is short-circuited or water-damaged. It's important to prevent moisture and water damage—my car once required costly repairs for this reason. Since then, I've made it a habit to clean the battery terminals and connectors monthly to avoid oxidation issues. Driving safety can't be taken lightly, as neglecting small issues can lead to major problems.

How long does it take to drive 180 kilometers?

How long it takes to drive 180 kilometers depends on factors such as speed, traffic lights, road conditions, weather, and traffic congestion. If calculated purely based on speed, at 90 km/h, it would take 2 hours to reach the destination; at a constant speed of 180 km/h, it would take 1 hour. In practical calculations, navigation software can be used to estimate the time. Modern navigation apps automatically determine the distance from the current location to the destination and provide intelligent analysis based on traffic lights and congestion along the route. The estimated arrival time may deviate slightly from reality, but the difference is usually not significant. If driving on highways, using the cruise control system can be beneficial. Maintaining speed manually by pressing the accelerator can cause fatigue, whereas cruise control allows the driver to rest their foot without losing speed, which is particularly helpful for long-distance driving. However, maintaining high concentration is still essential. Driving habits also significantly affect travel time. Some drivers tend to accelerate aggressively or brake frequently, while others may rely more on coasting or maintaining a steady speed. The former may increase speed but also fuel consumption, whereas the latter improves fuel efficiency and safety.

Which Car Paint Shop Can Achieve the Original Factory Finish?

No car paint shop can achieve the original factory finish. Car paint cannot be restored to its original condition. Even if the color is similar, upon close inspection, there will always be some differences. The reasons why it cannot be restored to the original condition are: Different types of paint used: First, the original paint on the car is factory paint, while the paint used for later repairs is touch-up paint. There is an inherent difference between the two. Different baking temperatures: Factory paint is high-temperature paint, baked at temperatures between 100-200 degrees Celsius, while touch-up paint is low-temperature paint, baked at only 70-80 degrees Celsius. Different spraying techniques and environments: Factory paint is applied in a dust-free environment and sprayed uniformly across the entire surface, ensuring consistent thickness and evenness. In contrast, repair paint is applied locally, and the accuracy of color matching and spraying technique can affect the uniformity and thickness of the paint, leading to color differences.
