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.

From a technical perspective, it is entirely feasible to run the air conditioning in a pure electric vehicle while it is turned off, as it is independently powered by the main battery and does not rely on the drivetrain. The air conditioning compressor is highly efficient in electricity usage but consumes significant energy, approximately 1-3 kilowatt-hours per hour, depending on the vehicle model and temperature settings. If your battery capacity is 50 kilowatt-hours, running the air conditioning for ten hours would consume 20-30% of the battery, equivalent to halving the driving range. During my tests of various electric vehicle brands, I found that intelligent systems can optimize power supply and reduce waste, but it is still necessary to monitor the battery level to avoid deep discharge, which can damage the battery. An additional reminder: prolonged use of air conditioning may cause the battery to overheat, affecting its lifespan. Setting a reasonable temperature and using ventilation mode can help mitigate this risk.

I am particularly concerned about safety issues when it comes to turning off a pure electric car and using the air conditioning. Although it is feasible, the risks are significant. Depleting the battery can leave the vehicle immobile, trapping you outdoors or in remote areas, which is dangerous. While electric cars do not emit exhaust fumes, in enclosed environments like garages, insufficient oxygen can lead to dizziness or even suffocation, with numerous cases reported. On one camping trip, my family and I slept in the car with the air conditioning on and woke up in the morning feeling chest tightness. Fortunately, we opened the windows in time. It is advisable to set a timer to turn off the air conditioning, maintain ventilation gaps, and avoid using it throughout the night.

As an environmental advocate, I believe using air conditioning in electric vehicles while parked should be done in moderation as it consumes electricity and increases carbon footprint. Running it for one hour is equivalent to driving several extra kilometers. I typically turn it on during hot noons or short waiting periods to avoid waste. It's better to use it while charging to take advantage of the grid's higher efficiency, or switch to natural ventilation to reduce energy consumption.

As an EV newbie just getting used to these features, turning on AC after shutting down a pure electric car is simple - just press a button or use the app, powered by the battery. But don't keep it running too long - last time I waited in a parking lot with AC on for half an hour and lost over 10 km of range. Pro tip: activating AC while charging won't harm the battery. Always avoid prolonged use in confined spaces - safety comes first.
