Electric vehicle PTC button usage method: Simply turn on the PTC button, then activate the blower switch. The car PTC button refers to the pure electric vehicle DC PTC heater switch, which is a ceramic heater. The electric vehicle PTC water heating system uses electrical energy to heat antifreeze, inheriting the heating system of fuel-powered vehicles to address issues such as defrosting, cabin heating, and battery insulation. The temperature PTC is a ceramic heating element that activates under low-temperature conditions, available in branch pipe and flat disc structural types, ensuring efficient utilization of generated heat with its simple structure, compact size, and easy installation.

When driving an electric vehicle, the PTC button usually represents the heating function—press it to warm up in cold weather. After starting the car, I look for the PTC button on the dashboard or center console—it might be labeled 'HEAT' or have a small flame icon. Press it, then rotate the temperature knob to set my desired comfort level, such as around 20°C. The system automatically starts blowing warm air. If the car has an automatic climate control mode, I also press the AUTO button to let it intelligently adjust the fan speed and airflow direction, saving me from manual adjustments. Remember to activate the PTC a few minutes before driving in winter to warm up the cabin, but avoid setting the temperature too high, as it can drain the battery quickly and reduce range. Beginners can follow these simple steps: press the button, set the temperature, and wait for warm air. Combining it with the recirculation button enhances the effect by preventing cold air from entering. I find it more energy-efficient than traditional heating and better for maintaining my EV's battery health.

As an experienced EV owner, I manage the PTC button to save power. In cold weather, I press the PTC to activate heating but strictly control the temperature between 18-22°C, as higher settings can significantly drain the battery. Press the button immediately after starting the car, set the temperature, and use it in combination with seat heating or steering wheel heating for better efficiency. I recommend preheating remotely via the app before departure or turning it on a few minutes in advance when parked to reduce the load while driving. In automatic mode, it intelligently switches between internal and external air circulation to keep the cabin air fresh. Avoid frequent use of PTC while charging to protect battery life. Personally, I recommend prioritizing seat heating and low fan speed, then reducing the intensity once the cabin is warm, which has minimal impact on range.

The PTC button in an electric car is the heating core, pressing it activates the hot air system. After starting the vehicle, locate the button labeled PTC or HEAT, press it, and adjust the temperature knob to over 20 degrees. In automatic air conditioning mode, it will manage the fan speed based on the settings. It's most effective to turn on the cabin preheating a few minutes before driving in cold weather. Combining it with the recirculation button to trap the hot air can save more energy. Remember not to set the temperature too high to avoid damaging the battery.

How many points are deducted for stopping once during parallel parking?

Stopping once during parallel parking deducts 5 points. Below is a related introduction to the deduction points for parallel parking: 1. Driving too slowly: Although the subject two test repeatedly emphasizes driving slowly, many students are afraid of being nervous and missing the test points, so they reduce the speed to a very low level, resulting in stalling. 2. Unfamiliar with the clutch: Not trying the tightness of the clutch before driving leads to discomfort during the test. 3. Inaccurate seat adjustment: If the seat adjustment is inaccurate, the candidate's sitting posture and vision will be affected, and it is easy to have deviations when looking at points, resulting in pressing the line. 4. Right turn signal: Previously, only the left turn signal was required when starting to park, but after the new regulations, many people forget to turn on the right turn signal before reversing, resulting in points deduction.
