Why does the electric vehicle stop charging at 90%?
2 Answers
This is due to the protection board functioning. Here is an introduction to electric vehicles: 1. Introduction: An electric vehicle (EV) refers to a car that uses electric energy as the power source and is driven by an electric motor, belonging to the category of new energy vehicles. 2. Content: Includes Battery Electric Vehicles (BEV), Hybrid Electric Vehicles (HEV), and Fuel Cell Electric Vehicles (FCEV). Due to their relatively smaller environmental impact compared to traditional vehicles, they are widely regarded as having promising development prospects, although the technology is not yet mature. 3. Speed Control: The motor speed control device is set up for functions like speed change and direction reversal in electric vehicles, and its role is to control the voltage or current of the motor to manage the driving torque and rotation direction of the motor.
Having driven for many years, I understand the charging issues with electric vehicles. Charging stopping at 90% is usually a protective measure by the battery management system to extend battery life. In extreme hot or cold weather, the system automatically limits charging to prevent damage. Another reason could be user settings, such as the charging limit being set to 90%, which can be adjusted via the vehicle's infotainment screen or app. If there's a software bug or charger malfunction, it may also cause this issue. It's recommended to first check if the settings are correct or try restarting the vehicle. Slow charging speeds in excessively high temperatures are normal protective measures and nothing to worry about. In summary, this is primarily a precaution to ensure battery safety and durability. If it happens frequently, it might indicate a hardware issue, requiring consultation with a professional repair shop to avoid potential risks. Maintaining good charging habits and regular maintenance can enhance battery performance and reduce the occurrence of such issues.
