Why is the EV function limited?
2 Answers
EV function is limited due to a fault in the vehicle's high-voltage system. Here is some relevant information about EVs: 1. Popularity: Although pure electric vehicle technology in China is already very mature, there are still difficulties in achieving industrialization in the short term due to various reasons. Industry experts point out that the widespread adoption of charging stations is key to the industrialization of pure electric vehicles. At the same time, national industrial policies should provide a favorable application environment for pure electric vehicles to promote their industrialization process. 2. HEV: The full name of EV on hybrid vehicles is HEV, which stands for Hybrid Electric Vehicle. Hybrid power means the vehicle uses both gasoline and electric drive systems. The advantage is that when the vehicle starts and stops, it relies solely on the generator. The engine does not work until a certain speed is reached. Therefore, the engine can always maintain optimal working conditions, with good power performance and very low emissions. The source of electrical energy is the engine, and it only requires refueling.
I've also experienced EV function restrictions while driving an electric car, which is largely related to the battery's condition. Both excessively high or low battery temperatures can trigger protection mechanisms, especially when driving after the car has been exposed to intense sunlight in summer. Low battery level is another common cause, as the system automatically limits power to prevent complete discharge. Charging system issues also warrant attention, such as a loosely connected fast-charging plug or unstable voltage from the charging station. Moisture-induced short circuits in high-voltage lines are quite dangerous too – once after driving in heavy rain, I got a restriction warning the next day. Lastly, software bugs can be the culprit; I encountered garbled error messages after an update once, which was resolved by restarting the infotainment system. If you face this issue, don't push your luck – getting it checked promptly is the safest approach.
