Recently, hybrid cars have become more and more popular, and we also need to start to understand some related knowledge of hybrid cars in order to better control the car.
On the Internet, there are different opinions about the battery life of the air conditioner in the pure electric mode of the hybrid car. 3 minutes? 5 minutes? 10 minutes? No one knows how long it takes.
At present, there are nothing more than two common types of hybrids on the market, the traditional gasoline-electric hybrid technology represented by Toyota and the plug-in hybrid technology mainly promoted by BYD and BMW.
Take Lexus CT200h as an example, this car has a lot to do with air conditioning technology. When we encounter a red light or a traffic jam, the CT200h will enter a pure electric mode. If the air-conditioning refrigeration system is turned on, the car will use a hidden large-capacity battery to power the air-conditioning compressor, thereby blowing a slow cool breeze; and When heating is needed in winter, this system is even more magical. The large-capacity battery will directly energize the electric heating device. It is no longer a dream to enjoy the warm currents in an instant, and it also saves you the trouble of not being able to provide hot air due to insufficient engine temperature.
Now the question is, if the big battery is exhausted, will it really fail to start? There is a very intelligent "electronic power control unit", PCU for short. When the PCU detects that the large-capacity battery is less than two bars, it will forcibly wake up the engine and charge the battery. When the battery reaches 60%, the engine stops charging. . In order to ensure safety and stability, Lexus hybrid vehicles have adopted more mature Ni-MH batteries.
And BMW, which advocates plug-in hybrid technology, is completely different from Lexus in terms of air conditioning technology. Also in terms of the BMW X1 new energy model, due to its own larger battery capacity, in most cases it can directly reduce the pressure through the converter to provide electrical energy for the auto ac compressor to achieve the cooling effect. When the engine temperature is insufficient and hot air is needed, BMW will wake up an efficient electric heating device to provide warm air in the car; and when the engine temperature reaches normal, it will switch to more traditional engine waste heat to provide hot air in the car. In this way, the endurance of the vehicle is greatly improved, and BMW is really capable of technical strength!
But even if you buy a BMW new energy vehicle, you must not take it lightly! When its large battery capacity is less than 30%, it will be forced to turn on the oil-powered mode, and the instrument panel will prompt you to charge in time. If things go on like this, the engine will not only bear the power output of the vehicle, but also charge the large battery part-time, and its fuel consumption can be imagined. Therefore, quickly find a charging pile is the best policy.
