In recent years, the automobile industry has undergone a large-scale transformation from fuel vehicles to electric vehicles such as new energy vehicles. New energy vehicle PCB is a unique circuit board specially designed for these electric vehicles. Since electric cars require more PCBs than conventional cars, the shift from conventional cars to electric cars has increased the demand for PCBs in the automotive world.

New energy automobile parts
New energy vehicles have unique components that make them different from traditional vehicles. Here are their components:
•Car charger: charge new energy vehicles as their energy source
•Power battery: provides power for vehicle accessories
•Energy storage: Store energy for vehicles
•Power Distribution: Distributes power to circuit boards and various components of the vehicle
•Drive motor: the power source that drives the vehicle
•Speed controller: regulates the speed of the vehicle
New energy vehicle power control system
New energy vehicles have three PCB-based main power control systems.
01. VCU – vehicle control unit
The VCU of new energy vehicles is mainly composed of control circuits and algorithm software. It is built on the PCB of new energy vehicles and regulates its operation. Its function is to supervise the vehicle and make decisions on the power control system. The PCB used to control the VCU is approximately 0.03 square meters.
02. MCU-Motor Control Unit
Similar to VCU, MCU is also composed of control circuit and algorithm software. The MCU regulates the vehicle’s electric motor according to the instructions of the VCU, so that the electric motor can send alternating current to the vehicle. The PCB of the MCU is approximately 0.15 square meters.
03. BMS-battery management system
BMS is an important part of the new energy vehicle battery system. The main function of BMS is to manage and protect the battery pack. BMS does this by performing multiple tasks. It collects and calculates voltage, current and SOC data to control battery discharge and charging. The BMU checks the voltage, current and balance control of the battery cells.
The hardware of BMS consists of BCU and BMU. The BCU component of the battery management system controls relays, estimates SOC and provides electrical protection. The BMU monitors voltage data, and battery current, and ensures control balance in the vehicle’s power control system. All these features of the BMS help prevent battery damage.
Due to the complexity of BMS, it requires a multilayer PCB for stability and proper operation. It also requires several PCBs. The main control unit requires approximately 0.24 square meters of PCB, and a single management system requires 2 to 3 square meters.
Application of new energy vehicle PCB in the automotive industry
New energy vehicle PCBs have a variety of applications in the automotive industry. Here are some of their popular applications:
•Braking System
•Engine control
•LED system
•ECU module
•ECL module
•GPS navigation
•monitor
•Radar system
Features of new energy vehicle PCB
New energy vehicle PCBs have some unique features that make them different from other PCBs. Here are some of the features:
Suitable for high temperatures
A major feature of new energy vehicle PCBs is high-temperature resistance. These PCBs have a lower density, which helps them dissipate heat. They have unique properties that make them suitable for high temperatures.
Reliable in a variety of environments
New energy vehicle PCBs are reliable and have a long service life because they are made of high-quality, high-strength materials. They are suitable for the harsh working conditions of automobiles and will not cause any damage even in different locations and under different environmental conditions.
Resistant to dirt
Vehicles attract dirt to themselves as they drive. To help protect these vehicles from dirt and its negative effects such as short circuits and failures, these PCBs are designed to be dust-proof. New energy vehicle manufacturers use various laminate materials on these PCBs to protect them from dust contamination.
