What are the five major parts of electric vehicles?

Electric vehicles are loved by consumers because of their environmental protection and convenience, so they have gradually become one of the important daily transportation tools. There are a total of five main parts of electric vehicles, which are called the five major parts of electric vehicles. Let's take a look below.　　1. The heart of electric vehicles-electric vehicle batteries　　 The vast majority of current electric vehicles are equipped with lead-acid batteries, because lead-acid batteries are low-cost and cost-effective. In 1860, Prantet of France invented a battery using lead as electrodes. The unique feature of this kind of battery is that when the battery voltage drops after a period of time, it can be supplied with reverse current to make the battery voltage rise. Because this battery can be recharged and can be used repeatedly, it is called a 'lead-acid battery'. 2. The brain of electric vehicles-electric vehicle controller The electric vehicle controller is the core control device used to control the start, run, advance and retreat, speed, stop and other electronic devices of the electric vehicle motor. It is like an electric vehicle. The brain of a car is an important part of an electric car. At present, electric vehicles mainly include electric bicycles, electric two-wheeled motorcycles, electric tricycles, electric three-wheeled motorcycles, electric four-wheeled vehicles, battery cars, etc. Electric vehicle controllers also have different performance and characteristics because of different models. . 3. The stomach of electric vehicles-electric vehicle chargers Electric vehicle chargers are a charging device specially configured for the batteries of electric bicycles! The classification of chargers: It can be distinguished with and without power frequency (50 Hz) transformers. Two categories. Freight three-wheel chargers generally use chargers with power frequency transformers, which are bulky, heavy, and electricity-consuming, but reliable and cheap; electric bicycles and electric motorcycles use so-called switching power supply chargers, which save electricity and are efficient, but Perishable.　　Four. The intestines of electric vehicles-electric vehicle converter 　　 The main function of electric vehicle converters is voltage conversion, which is used for lights, horns, etc., which is equivalent to the intestines of electric vehicles.　　Fifth, the limbs of electric vehicles-electric vehicle motors 　　 according to its use environment and frequency of use, the form is also different. Different types of motors have different characteristics. Currently, permanent magnet DC motors are commonly used in electric vehicle motors. The so-called permanent magnet motor refers to a method in which the motor coil is excited by permanent magnets instead of coil excitation. This saves the electric energy consumed by the excitation coil and improves the electromechanical conversion efficiency of the motor. This can reduce the driving current and extend the driving range for electric vehicles that use limited energy on-board. Electric vehicle motors are classified according to the energization form of the motor, which can be divided into two categories: brushed motors and brushless motors; according to the mechanical structure of the motor assembly, they are generally divided into 'toothed' (the motor speed is high, and it needs to go through the gear Deceleration) and 'toothless' (motor torque output does not undergo any deceleration) two categories.
