Can a pure electric vehicle keep the air conditioning running continuously when turned off?

Pure electric vehicles cannot keep the air conditioning running continuously when turned off. Below is an introduction to pure electric vehicles: 1. Components of an electric vehicle: The components of an electric vehicle include the electric drive and control system, mechanical systems such as the drivetrain, and working devices to complete designated tasks. The electric drive and control system is the core of an electric vehicle and also the biggest difference compared to internal combustion engine vehicles. The electric drive and control system consists of the drive motor, power source, and motor speed control device. Other components of an electric vehicle are basically the same as those in internal combustion engine vehicles. 2. Power source for electric vehicles: The power source provides electrical energy to the drive motor of an electric vehicle, which converts the electrical energy into mechanical energy. The most widely used power source is lead-acid batteries, but with the development of electric vehicle technology, lead-acid batteries are gradually being replaced by other types of batteries due to their low energy density, slow charging speed, and short lifespan.
As a long-term electric vehicle owner, I often turn on the air conditioning after turning off the engine to rest or wait for someone, which is indeed very convenient. Pure electric vehicles can operate the air conditioning system normally after the engine is turned off, powered by the high-voltage battery, unlike gasoline cars that require the engine to be running. However, the power consumption is quite significant, especially when cooling in hot weather, which may consume 5-10% of the battery per hour, equivalent to reducing the range by several dozen kilometers. Once, I took a short nap with the air conditioning on at a highway service area, and after an hour, I found that the battery had dropped by half, almost causing me to miss my trip. It is advisable to use it only for short periods and avoid leaving it on all night to prevent the battery from being depleted and the vehicle from starting. Safety-wise, it's also important not to use it in enclosed garages; although electric vehicles have no exhaust fumes and lower risks, poor ventilation can still cause discomfort due to insufficient oxygen. Turning on the air conditioning while charging is a wise choice to save battery life.
