The working principle of 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. It is like the brain of the electric vehicle and an important part of the electric vehicle. The following two-wheeled electric vehicle will introduce to you what the working principle of the electric vehicle controller is.

Briefly speaking, the controller is composed of peripheral devices and the main chip (or single-chip microcomputer). Peripheral devices are some functional devices, such as execution, sampling, etc., which are resistors, sensors, bridge switch circuits, and auxiliary single-chip or application-specific integrated circuits. The device for controlling the process; the single-chip microcomputer is also called the microcontroller. The two-wheeled electric vehicle is an integrated chip that combines the memory, the decoder with the signal language conversion, the sawtooth wave generator, the pulse width modulation function circuit and the switch circuit The power tube is turned on or off, and the on time of the power tube is controlled by a square wave to control the motor speed. The drive circuit, input and output ports, etc. are integrated in a company to form a computer chip. This is the intelligent controller of the electric bicycle. It is a high-tech product that appears as a "fool".

The design quality and characteristics of the controller, the function of the microprocessor used, the power switch device circuit and the layout of peripheral devices, etc., are directly related to the performance and operating status of the vehicle, and also affect the performance and efficiency of the controller itself. The controller, used in the same Scooter, equipped with the same set of batteries in the same charge and discharge state, sometimes shows a big difference in the driving ability.
