The development of the PCB controller solution is the most important link in the manufacture of electric vehicles. In the simplest terms, the PCB controller is the bridge that connects the battery energy with the motors that drive the wheels. The process when the driver steps on the accelerator pedal is the process of operating the controller. The role of the controller is equivalent to the PCB rheostat in the dimmable light at home.

 The traditional internal combustion engine can limit the speed when the torque is efficiently generated to a narrow range, which is why the traditional internal combustion engine car needs a large and complicated transmission mechanism; and the electric motor can efficiently generate torque in a fairly wide speed range. , In the process of pure electric vehicle driving, no gear shifting device is needed, which is convenient and easy to operate and has low noise. Compared with hybrid vehicles, pure electric vehicles use a single electric energy source. The electronic control system greatly reduces the internal mechanical transmission system of the vehicle, the structure is more simplified, and the energy loss and noise caused by the friction of mechanical parts are also reduced, thus saving the internal space of the vehicle. weight.

       In the car, it is connected to the accelerator pedal, which can make the PCB current output power change within a certain range. The current supplied by the battery to the motor is regulated by the controller. Electric vehicles use high-efficiency, high-power alternators, and the controller is responsible for converting the direct current in the battery into alternating current. The motor responsible for driving the wheels in an electric vehicle is also called a traction motor. AC induction motors and AC permanent magnet motors are currently the most widely used types of motors. They have the characteristics of high torque, stable operation and light weight. The stator in the motor uses the alternating current transmitted from the power system to generate a magnetic field, and the rotor inside the stator is responsible for converting electrical energy into mechanical energy for output. In addition to the role of power transmission, the motor can also reversely charge the battery. At this time, the motor is called a "generator". When the electric vehicle is decelerating, the braking energy recovery system transfers electrical energy back to the battery through the motor. An electric vehicle can be equipped with one or more motors, and some adopt the method of in-wheel motors, which directly install the motors inside the wheels. After comprehensively considering the advantages and disadvantages of the in-wheel motor, the vehicle structure is simplified but the unsprung mass is increased. motor driven

Compared with the traditional internal combustion engine drive, the advantage is that its energy utilization rate is higher, and the maximum torque can be reached from the beginning, which is far superior to the internal combustion engine in vehicle acceleration performance.

With the gradual rise of the green new energy economy, electric vehicles are popular among consumers for their light, fast, environmentally friendly, energy-saving, and affordable characteristics. Following this, the homogeneity of products has become more and more serious, and the fight caused by prices has become more and more fierce. In contrast, Gao Biao Technology invests heavily in PCB technological innovation and PCB product development equipment updates every year. Based on the analysis of existing market problems, we are responsible for guaranteeing the benefits of our PCB brand and consumers. Gaobiao Technology has been engaged in independent development and has launched a series of electric vehicle drive products with stable performance and first-class quality.
