Introduction of charging equipment for electric vehicle charging
There are four kinds of charging connections commonly used in electric vehicles:
First, the portable charger carried on the vehicle is used, and the electric vehicle will be equipped with the portable charger on the vehicle so that the owner can charge it through the household power supply. The main feature is convenience. However, its slow charging speed is somewhat maddening, which can only be used as another way to supplement electricity.
Second, household charging piles. When buying an electric car, a household charging pile is usually given along with the car, and technicians will be arranged to install and debug it at home. The charging time of this charging method is OK, and it will be different with different vehicle brands and models, but the premise is that there is a parking space and the property allows you to install a household charging pile in the parking space.
The third way is the public charging pile. The advantage of this charging method is that it can choose DC fast charging and AC slow charging according to the actual situation, and it is also the only place that supports DC fast charging, but its disadvantages are also obvious. Public charging piles are less built at this stage, which are not easy to find and take up, and the charging cost is higher.
The fourth way to charge is to change the battery. This is also the last trick of electric vehicles. Specially trained technicians can replace batteries within 2-10 minutes with fully automatic or semi-automatic technology, thus achieving the refueling speed comparable to that of fuel vehicles. However, the shortcomings of this method are obvious, which can only be operated by professionals in professional places, and the replacement batteries are uneven, which makes people worry.
Generally speaking, the charging methods of electric vehicles are flexible and diverse, and they can be selected scientifically and reasonably according to their own actual conditions, which can not only not affect the normal use of electric vehicles, but also save the charging cost, which is economical and practical.
The technical principle of electric vehicle charging. Motor and Control System Pure electric vehicles use motors instead of fuel engines, which are driven by motors without automatic transmission. Compared with an automatic gearbox, the motor has a simple structure, mature technology, and reliable operation. The traditional internal combustion engine can limit the rotating speed when generating torque efficiently in a narrow range, which is why the traditional internal combustion engine car needs a huge and complex speed change mechanism; However, the motor can efficiently generate torque in a wide speed range and does not need gear shifting and speed changing devices in the driving process of pure electric vehicles, which is convenient and easy to operate and low in noise. Compared with hybrid electric vehicles, pure electric vehicles use a single electric energy source, and the electronic control system greatly reduces the internal mechanical transmission system of the vehicle, thus simplifying the structure, reducing the energy loss and noise caused by the friction of mechanical parts, and saving the internal space and weight of the vehicle. The motor drive control system is the main executive structure of the new energy vehicle. The drive motor and its control system are one of the core components (battery, motor, and electronic control) of the new energy vehicle. Its driving characteristics determine the main performance index of the vehicle, and it is an important component of the electric vehicle. The fuel cell vehicles (FCV), hybrid electric vehicles (HEV), and pure electric vehicles (EV) all use motors to drive their wheels. Choosing suitable motors is an important factor to improve the performance-price ratio of all kinds of electric vehicles. Therefore, it is extremely important to develop or improve the motor drive mode which can meet all the performance requirements of vehicles while driving and has the characteristics of durability, low cost, and high efficiency.
After reading these introductions, do you have a certain understanding of the electric vehicle charging connection? You should be familiar with this content. After all, new energy vehicles are also very important to us. Not only is the era of science and technology, but also the concept of time is also very important. I hope you can learn more about car knowledge. Finally, I hope that our introduction can help you.You can get more information by contacting us.
