Today, I want to putcarIntroduce the content to everyone.Many friends know that there are many on the roof of our carAccessories, And it looks smaller and smaller, but their functions and uses are very large. In fact, our electric cars and cars are a principle. There are many accessories on electric cars, so let's find out.

　　Introduction of electric car accessories: motor
The motor is the main component of an electric vehicle. It is very important to select the appropriate motor type and reasonable rated parameters. For example, it is not accurate to represent a motor with 10 horsepower or 15 horsepower (1 horsepower = -735.499W) because the power varies with voltage and current, and the peak power is much higher than the continuous power. Use the same index to compare the engine and the gasoline engine. Because the engine has continuous power under load, the gasoline engine gives peak power without load dynamometer. For the sake of accuracy, motors should be identified by name or type. There are several types of motors commonly used in electric vehicles. one. Series excitation brush DC motor Series excitation brush DC motor (field winding and armature in series) is an electric vehicle currently running on the road (splashing water tank). This motor has the highest torque, is cheaper than other types of motors, and has a wide range of applications. The controller is relatively simple. 2. High-speed AC motors require decelerating, expensive and complicated speed regulation devices. three. Brushless DC motors require expensive controllers, but they require very little maintenance. Four.Permanent magnet motor (pmm) in a very narrowRotating speedIt has high efficiency in the range, and the speed change during normal driving will make its efficiency drop rapidly. 5 pcs. Compared with series excitation motors, parallel excitation and compound excitation motors have higher manufacturing costs and higher acceleration performance.
Introduction of electric vehicle parts: motor controller
The motor controller is an integrated circuit, through active operation, according to the set direction, speed, angle and response time to control the motor work. In electric vehicles, the function of the motor controller is based on gears,ThrottleandBrakeThe command converts the electric energy stored in the power battery into the electric energy required to drive the motor, thereby controlling the starting operation, forward and backward speed, climbing force and other driving conditions of the electric vehicle. Or help electric vehicles to brake and store some of the braking energy in the power battery. It is one of the key components of electric vehicles. CNC programmable stepper motor controller can use stepper motor driver and stepper motor to form a complete stepper motor control system. It can control three stepping motors to run time-sharing. The controller adopts a computer programming language and has commands such as input, output, and counting. It has the characteristics of flexible programming and wide adaptability, and can be widely used in various control automation fields. What are the electric car accessories?

　　Introduction of electric vehicle parts: DC7DC converter
Electric vehicles usually use 12V auxiliary batteries to power the original 12V accessories (such as lights, speakers, etc.).However, unlike gasoline vehicles, electric vehicles do not communicateDynamoCome to charge the battery. One way is to use a 12-volt battery, which can be charged and discharged deeply. The capacity is as large as possible, but if you plan to drive at night, the power is not enough. When the battery is exhausted,HeadlampWill darken,Turn signalIt will flash slowly. If certain parts of the drive system cannot obtain the necessary signals powered by the auxiliary battery, it may also affect the operation of the car. Another method is to connect 12V from the two modules of the main battery pack, but it will cause uneven discharge of the battery pack and affect the performance and life of the battery. A better method may be to use a dc/dc1 converter. DC7DC reduces the voltage across the battery to 13.5V, which is the same as the rated output of the alternator. Since the Dc/DC converter is connected to the entire battery pack, there is no uneven discharge, and the required current is very low, which has little effect on the driving range, and does not require a single 12V charging circuit to charge the auxiliary battery. For safety reasons, it is not recommended to completely remove the auxiliary battery. At night, if the DC/DC converter fails or the battery voltage is lower than the converter's cut-off voltage, the auxiliary battery has enough power to drive the car home. Because the battery is not used to start the gasoline engine, it can be replaced with a smaller starter battery.
