What is an electric vehicle?
An electric vehicle is a relatively common form of transportation, in short, it is a locomotive driven by electricity. Electric vehicles, as of now, mainly include electric bicycles, electric two-wheeled motorcycles, electric tricycles, electric three-wheeled motorcycles, electric four-wheeled vehicles, electric battery cars, etc.
There are two major types of electric vehicles, one is to connect to external power lines to obtain electricity, and the other is to use batteries as electricity.
How does it work in electric vehicle?
After the new energy electric vehicles become popular, you will often hear about the DC-DC converter. DC-DC converter is a very important component on electric vehicles. The first DC power refers to the DC power of the power battery, which is the high-voltage DC power. At this stage, the voltage of high-voltage DC power supply of electric vehicles is generally above 200V, and some models may reach 800V high voltage. The second DC power refers to the power supply used by electrical appliances on the car, such as meters, audio, LCD screen, air conditioning, electric glass lift, horn, lighting and so on.

These electrical devices must use a low-voltage safety power supply, which allows the equipment to work properly on the one hand, and ensures the safety of the operator on the other. Generally use a 12V or 24V DC power supply, the most common and intuitive component is the 12V battery in the car. Two DC power supplies, one high and one low, make a big difference.
How to convert the high-voltage DC power into a low-voltage DC power that can be used by the appliances in the car? This is the ultimate role of the DC-DC converter and the most basic job function of the DC-DC converter.
The role of the electric car converter is to convert the voltage of the battery into the working voltage of the electric appliances (such as horn, meter, lights, etc.) on the electric car. The electric car converter is the core control device used to control the start, run, advance and retreat, speed, stop, and other electronic devices of the electric car, it is like the brain of the electric car, which is an important part on the electric car. Electric vehicles do not start at full load and require the use of this converter in order to regulate the engine like the throttle of a car.
The voltage to current converter is a circuit that converts the input voltage signal into a current signal, and is a current source for voltage control. In the long distance transmission of analog signals by voltage, the signal source resistance or DC resistance of the transmission line, etc. will cause voltage attenuation, and the lower the input resistance at the signal receiving end, the greater the voltage attenuation.
