It refers to the DC PTC heater in electric vehicles, which is a type of ceramic heater. Since the advent of electric vehicles, PTC heaters have been widely adopted. For example, Mitsubishi Motors' "i-MiEV" uses a PTC heater to heat circulating water, while Nissan's "Leaf," launched in 2010, employs a PTC heater to directly heat the air. Characteristics of PTC thermistors: PTC thermistors are known for their constant temperature heating, long natural lifespan, energy efficiency, absence of open flames, excellent safety performance, and easy control of heat output. Main applications of the product: The product is mainly suitable for auxiliary PTC heaters in new energy electric vehicle air conditioners, car air conditioners, household air conditioners, central air conditioners, heaters, clothes dryers, dehumidifiers, humidifiers, water purifiers, foot baths, etc.

The PTC button on new energy vehicles actually refers to the control button for the Positive Temperature Coefficient heater. Simply put, it's a switch that helps you activate the heating function inside the car. When I was learning about electric vehicles, I noticed that it's usually located on the air conditioning control panel, possibly labeled 'PTC' or with a warm air symbol. Since electric vehicles don't have engine waste heat, you need to press this button in winter to activate the built-in heater for warmth. PTC technology means that as the heating element's temperature rises, it automatically reduces power, making it efficient and safe without the overheating risks of older cars. I find it particularly practical—it heats up quickly in low temperatures, and with just a press, the car interior warms up. However, it's important to note that it consumes electricity; for example, when range is short, it's best to lower the temperature and use seat heating to save energy. When driving, I usually set the air conditioning to auto mode to avoid keeping the PTC on continuously, which helps protect battery life. The button is designed to be user-friendly, making it easy even for beginners to operate.

In my daily driving of a new energy vehicle, I frequently use the PTC button, which is a heating control button in the air conditioning system, representing the Positive Temperature Coefficient heater. From the driver's seat, pressing it activates the heating element in the AC to provide warm air—especially indispensable during winter drives in northern regions. I've noticed that since electric vehicles lack engine heat, the PTC button effectively fills this gap. It's typically located in the control area near the steering wheel, possibly integrated within the temperature adjustment buttons. Operation is straightforward: a simple press toggles it on or off. I also recommend checking the battery status before use; minimizing usage when the charge is low helps avoid reduced driving range. Actually, PTC heating is quite intelligent—it automatically adjusts power output when temperatures rise, ensuring high safety standards. I prefer setting a target temperature to let the system auto-regulate airflow, achieving both comfort and energy efficiency while extending component lifespan.

The PTC button in new energy vehicles is a heater switch button, which stands for Positive Temperature Coefficient. Having used this car for several years, I can say it's simply a button on the air conditioning panel marked with a heat symbol. Pressing it activates the auxiliary heating, especially helpful in cold weather to warm you up. Unlike traditional fuel-powered cars where the engine generates heat, electric vehicles rely on the PTC button to activate electric heating for warm air. The advantage is that PTC heating is highly efficient and safe, with self-regulating temperature features that prevent overheating or damage. It's easy to locate—just look for the heat symbol among the air conditioning buttons. For usage, it's advisable not to keep it on high fan speed continuously; setting a moderate temperature protects the battery and ensures safe driving.
