In recent days, one after another cold wave swept the country, so that everyone felt the real winter, every year to this season everyone is most worried about entering the car in the morning, really where to touch where cool ah, but the traditional fuel car is fine, endure more than 10 minutes of water temperature up the car is also warm, the most difficult in winter is also a new energy electric vehicle, some people say that electric vehicles do not also have air conditioning, electric vehicles do have air conditioning, after opening, there is no need to wait for the water temperature to come up directly there is a temperature, But the biggest problem with the electric vehicle to open the warm air is that the endurance decline is particularly serious, which is also the winter on the road of the electric vehicle either glass are ha gas, or the driver of the car wrapped themselves tightly, in short, in order to survive the cold rather than willing to open the air conditioning, then according to this electric vehicle winter can not open the air conditioning? It is not that in recent years, electric vehicles will be equipped with heat pump air conditioning, heat pump air conditioning will be better than electric air conditioning power consumption, today to say what is the heat pump air conditioning.
What is a heat pump air conditioner
Heat pump air conditioning from the literal simple understanding is with heat pump air conditioning (as if it is a nonsense), this heat pump, can be regarded as the usual pumping pump, heat pump air conditioning and water pump generally mean the same concept, one is to carry water, one is to transport heat, heat pump air conditioning work process is to carry heat, but heat pump air conditioning is not only to carry heat, summer needs of air conditioning can also be, compared to the general single cold air conditioning, heat pump air conditioning cost will be higher, This is also why heat pump air conditioners will be on the more expensive electric vehicles, and now heat pump air conditioners are not a strange thing, such as BYD Dolphin.
Heat pump air conditioning and ordinary air conditioning are different
Heat pump air conditioning compared to ordinary air conditioning, in addition to the name of the difference, the two in the effect is not much difference, here is the final effect, the purpose is to provide heat to the car, but if the working principle of the two differences are still very large, especially the energy consumption part is also very different, before saying that the first simple science popularization of the traditional fuel vehicle air conditioning is through the engine to drive the compressor for refrigeration, if it is heating, it is more simple, directly use the engine coolant circulating water temperature can achieve the purpose of heating, But the new energy model does not have an engine, everything is electrified, the air conditioning compressor also needs electric drive, if the winter needs warm air, the early electric vehicle will generally use PTC air conditioning, PTC is to achieve the purpose of heating by heating the heating wire, and heat pump air conditioning compared to the PTC structure will be more simple, popularly speaking PTC air conditioning heating method is like the small sun used at home in winter, the heating effect is good, but the power consumption is very large, for what needs electricity to drive the electric vehicle is obviously not the best choice, According to the endurance standard to calculate, the use of PTC air conditioning model 100 km endurance will be less than the heat pump air conditioning about 30 kilometers, in fact, short-distance driving then the heat pump air conditioning and PTC air conditioning gap is not very large, if the driving distance is relatively long the gap may be obvious, but now how many people will choose to drive electric vehicles to run long-distance, can not say that there is no can only say that it is particularly small, especially in winter, electric vehicle endurance discount is really too serious.
Currently what cars use heat pumps for air conditioning
Since the above said that the heat pump air conditioning will be helpful to the endurance of electric vehicles, then the electric vehicles on the market are using heat pump air conditioning, in fact, it is not so, the following is simply to tell you a few electric vehicles with car pump air conditioning, first of all, about 100,000 electric vehicles BYD Dolphin, 10 to 200,000 Volkswagen ID.4, WM W6, Xiaopeng P5, Roewe Ei5, 200,000-300,000 Tesla Model 3, Model Y, Volvo XC40 (new energy) Polar Fox Alpha S, etc. More than 300,000 Tesla Model S, Model X, Extreme Kr 001, Nio ES6, ES8, BMW iX3, Audi e-tron, Mercedes-Benz EQC, Volkswagen ID.6, Porsche Taycan, Jaguar I-PACE, Hongqi E-HS9, Gaohe Hiphi X, from the name and price of the vehicle, it can be seen that heat pump air conditioning is used more on high-end electric vehicles.
Is air conditioning really not working without a heat pump?
Combined with the above price like Xiaopeng P7, BYD Han these two more representative electric vehicles also do not use heat pump air conditioning, and still use PTC air conditioning, there are many reasons for not using heat pump air conditioning, first of all, there are many reasons for the cost, the use of heat pump air conditioning will increase the production cost of the whole vehicle, in addition, heat pump air conditioning also faces a problem, that is, in relatively cold weather, the heating effect is not very good, this point is compared to the ordinary PTC air conditioner open there is a hot air is a deficiency, heat pump air conditioning in some conditions The advantage is not obvious , at the beginning also mentioned that the heat pump air conditioning needs to transport heat to the car, which does not exclude the loss of heat before, even if the heat pump air conditioner is how to save points, the heating efficiency is slow to use when it is cold, the power consumption is similar to the PTC air conditioner, for a simple example, when you open the PTC air conditioner to heat the car to 18 degrees Time it takes 10 minutes, the power consumption is 2kWh, and the use of heat pump air conditioning in the cold weather will heat the car to 18 degrees Time used for 30 minutes, power consumption 4kWh, heat pump air conditioning heating effect is not obvious And the time is also longer, and the power consumption will follow up after a long time, which is probably the meaning, and the above view is only an example and does not represent the actual experience.
summary
In fact, there are many factors affecting the endurance of electric vehicles in winter, if you rely on a heat pump air conditioner to improve the electric vehicle in the winter endurance difference, then the electric vehicles on the market are using heat pump air conditioning expensive points are also cost-effective, but in fact, the real use of heat pump air conditioning in the environment is not so powerful as the Internet said, especially you want to achieve a relatively high problem, heat pump air conditioning is still difficult to achieve, but compared to PTC air conditioning heat pump air conditioning can indeed do save electricity, but the amount of electricity saved is not obvious, Take the core battery of the electric vehicle, the electrolyte conductivity inside the winter battery will become worse, the colder the weather is obvious, the greater the electrolyte resistance, the greater the power consumption of the vehicle, if the service life of the vehicle is more than a little more power consumption will be more obvious, so a 600 km endurance standard electric vehicle in the actual use of winter will be 60% off or even 50% off after conversion, is almost the actual mileage, in recent years, especially in the limited city, more and more people have given up the blue card to choose the pure electric green card, Although it solves the license plate and car demand, but has entered the winter problem day by day more, the most confusing is the endurance, in addition to more and more electric vehicles, many communities can not install private charging piles, to the outside charging problems more, queuing, time-consuming, parking fees, and finally calculated down the electric car not only not than the fuel car to save money or even more expensive, for electric vehicles My view is that if the home can not install charging piles, it is best not to buy, because the name of electric dad is not called in vain.
