With the rapid development of science and technology, electric vehicles have gradually entered our lives. Compared with traditional fuel vehicles, electric vehicles have obvious advantages in environmental protection and energy saving, however, in the extremely cold weather in winter, the question of whether electric vehicles need to be warmed has attracted widespread attention. This article will unify the brake fluid from a professional point of view, ** the answer to this question.
First of all, we need to understand what a hot car is. In traditional fuel vehicles, the engine needs to run for a period of time to reach optimal working condition. This process is known as a hot car. The purpose of the hot car is to make the engine oil lubrication system fully establish pressure and ensure the lubrication between the various parts of the engine. At the same time, the hot car can also increase the water temperature of the engine, improve the combustion efficiency and reduce emission pollution.
So, do electric cars also need to be hot-up?The answer is yes. While electric vehicles are powered by electric motors, they work differently than conventional combustion vehicles. When the battery pack of an electric vehicle is in a low temperature environment, its charging and discharging performance will be affected, resulting in a decrease in cruising range. Therefore, in extremely cold weather, it is very necessary to warm up electric vehicles.
However, the process of warming up an electric vehicle is very different from that of a conventional combustion vehicle. For traditional fuel vehicles, the hot car is mainly achieved by the operation of the engine. In the case of electric vehicles, the hot car is mainly achieved by heating the battery pack. The hot-up process of an electric vehicle mainly includes the following aspects:
Preheating the battery pack: In extremely cold weather, the temperature of the battery pack of an electric vehicle can drop rapidly, affecting the charging and discharging performance. By preheating the battery pack, the temperature of the battery pack can be increased to ensure that it works normally in a low temperature environment.
Preheating the motor: When the motor is in a low temperature environment, the viscosity of its internal lubricating oil will increase, resulting in difficulty in starting. By preheating the motor, the lubricating oil can reach a suitable working state and improve the starting performance of the motor.
Preheating the air conditioning system: When using the air conditioner in winter, the burden on the air conditioning system increases due to the large temperature difference between indoor and outdoor. By preheating the air conditioning system, energy consumption can be reduced and the air conditioning effect can be improved.
It is important to note that the process of warming up an electric vehicle is not simply to drive the vehicle for a period of time. At present, some electric vehicles on the market have automatic warm-up function. When the ambient temperature drops below a certain value, the vehicle automatically initiates a warm-up program to preheat the battery pack, electric motor, and air conditioning system. This preheating method can not only ensure the normal use of electric vehicles in extremely cold weather, but also improve energy efficiency.
In conclusion, Unified Brake Fluid believes that electric vehicles do need to be warmed up in extremely cold weather. Compared with conventional combustion vehicles, the hot-up process of electric vehicles is simpler and more efficient. By preheating the battery pack, electric motor and air conditioning system, the normal use of electric vehicles in low temperature environments can be ensured and energy efficiency can be improved. Therefore, when driving an electric vehicle in winter, we need to pay attention to proper warm-up of the vehicle to ensure driving safety and extend battery life.
