Can an electric vehicle be charged while the power is on?
2 Answers
An electric vehicle can charge its battery while the power is on, but it is recommended to disconnect the power during charging. Electric vehicles are a mode of transportation chosen by many consumers due to their lightweight, flexibility, and fuel-free operation, making them ideal for navigating congested urban roads. Below is some basic information about electric vehicles: 1. The battery is a crucial component of an electric vehicle, responsible for storing electrical energy. 2. The battery is a wearable part that requires periodic replacement, as its performance degrades with the increase in charge and discharge cycles. 3. The battery consists of a casing, electrolyte, separator, positive electrode, and negative electrode. 4. Ions in the battery move within the electrolyte, but some ions react with the electrolyte during this process, leading to a reduction in the number of ions inside the battery. 5. A decrease in the number of ions in the battery results in a reduced energy storage capacity.
I've been driving an electric vehicle for several years and often need to charge while the car is still running with the air conditioning or other devices on. Generally speaking, charging is possible with the power on, but it depends on the specific model and charging method. For example, with my car, if it's parked at a charging station with the charging port connected, and the fan or central control screen is on, the charging process can still proceed normally without interruption. However, I don't recommend doing this because the vehicle's system may become overloaded, especially during fast charging when the current is high and the battery temperature rises quickly. Adding the operation of internal electrical devices can easily lead to overheating risks. Additionally, charging while the car is in motion is completely impossible. Electric vehicles can only be charged when turned off and stationary; otherwise, the powertrain system will conflict. It's best to develop the habit of turning off the car before charging to ensure safety and efficiency. Don't overlook details to save time, as battery life and driving safety come first. Regular charging habits can also extend the lifespan of an electric vehicle and avoid unnecessary maintenance troubles. Overall, charging with the power on is technically feasible, but it's neither practical nor recommended.
