Applications of Heavy Copper PCB in New Energy Vehicles

With the rapid growth of the new energy vehicle market, the demand for battery management systems, motor control and power conversion equipment is also increasing. These systems require reliable transmission of high current carrying capacity, and heavy copper PCBs are an ideal choice due to their superior conductivity and durability. This article will explore the applications and advantages of heavy copper PCB in new energy vehicles.

Definition and Characteristics of Heavy Copper PCB

Heavy copper PCB refers to PCB with copper foil thickness exceeding 1OZ, and common thicknesses are 2OZ, 3OZ and even 4OZ. Compared with ordinary PCB, heavy copper PCB has the following significant characteristics:

1) High Current Carrying Capacity: Heavy copper PCBs can reliably carry currents up to 400A+, making them ideal for applications requiring stable, high-current-carrying traces.

2) High Temperature Resistance: Heavy copper PCB has effective heat dissipation function, which can reduce heat accumulation, thereby improving the service life and stability of PCB.

3) High Mechanical Strength: Heavy copper PCB improves the mechanical strength of PCB, allowing it to remain stable in harsh working environments.

Specific Applications of Heavy Copper PCB in New Energy Vehicles

1) Motor Control

The motor control system of new energy vehicles needs to handle high current and high voltage, and heavy copper PCB is regarded as an ideal solution due to its excellent conductivity and heat resistance. The extra-thick copper layer not only ensures the stable transmission of large currents, but also dissipates heat efficiently, thus ensuring the stable operation of the system.

2) Power Conversion

As one of the key components of new energy vehicles, the power converter's main function is to efficiently and stably convert battery energy into the power required to drive the motor. Here, heavy copper PCBs performs well under the demand of high power density and high-efficiency energy conversion with their high current carrying capacity and high temperature resistance, thus ensuring the efficient operation of the power converter.

3) Battery Management System

The battery management system (BMS) is mainly responsible for monitoring and managing the charge and discharge status of the battery to ensure battery safety and performance. The application of heavy copper PCB in BMS supports the design of high current paths and reduces resistance losses, thereby improving the reliability and safety of the system.
