The rapid development of new energy vehicles can not be separated from the wide application of printed circuit boards (PCB), the following is the specific embodiment of PCB in the main systems of new energy vehicles:

Battery Management System (BMS)

  • Circuits on PCB can accurately measure battery voltage, current, temperature, and other parameters. Provide accurate data for battery status assessment, and timely detection of overcharge, over-discharge, overheating, and other abnormalities. Take protective measures to extend battery life.
  • Realize the equalization management of the battery to ensure the balance of power of each battery unit. Improve the overall performance of the battery pack.
  • The communication interface interacts with the vehicle control system to realize remote monitoring and management of the battery.

Drive Motor Controller

  • The power circuit on the PCB converts the DC power from the battery to the AC power required by the motor. It realizes efficient driving of the motor, and at the same time, it has regenerative braking function, which recovers the braking energy of the car and stores it in the battery. Improves energy efficiency.
  • The control circuit controls the motor speed and torque accurately according to the driver’s operating instructions and the vehicle’s driving status. Accurately control the speed and torque of the motor to realize the smooth running of the car.
  • The communication interface interacts with the vehicle control system to realize the cooperative control of the motor.

High Voltage Distribution System

  • The high-voltage circuit on the PCB realizes the safe transmission and distribution of high-voltage electricity. Ensure the normal operation of each high-voltage electrical device, and at the same time, it is equipped with protection functions such as over-current, over-voltage, and short-circuit. Improves system safety.
  • The low voltage circuit realizes the control and monitoring of the high voltage distribution system. Such as controlling the high-voltage contactor on and off, monitoring the high-voltage electrical status, etc.
  • The communication interface interacts with the vehicle control system to realize remote monitoring and management of the high-voltage distribution system.

PCB plays an important role in several key systems of new energy vehicles. With the continuous progress of technology, its performance and reliability will be continuously improved to provide stronger support for the development of new energy vehicles.
