What are the specific applications of copper foil products in new energy vehicles?

The specific applications of copper foil products in new energy vehicles mainly include the following aspects:

1. **Thick copper foil PCBs in new energy vehicles**:
   - **High-power charging piles and EV power supply equipment**: thick copper foil PCBs can meet the carrying capacity of new energy vehicle charging equipment for high voltage and high current, such as DC charging piles (fast charging piles).
   - **Inverters for EV**: Thick copper foil PCBs can reduce heat generation and increase the heat dissipation performance of inverters, which helps to improve the stability and efficiency of inverters.
   - **Electronic Control Unit (ECU)** for EV: Thick copper foil PCB helps to improve the wiring density and heat conduction-expansion performance of ECU, which meets the stringent requirements of ECU for high current and heat dissipation.

2. **Electrolytic Copper Foil Application in New Energy Vehicle Power Battery**: Electrolytic copper foil is an ideal base material for lithium battery negative electrode, which can be used as a carrier for the negative electrode active substance, conduct the negative electrode electrons, and play the role of pooling current. In the field of new energy vehicles, electrolytic copper foil is mainly used as a collector in lithium-ion batteries.

To summarize, the application of copper foil products in new energy vehicles mainly involves power transmission, energy conversion and control and other key areas, which is of great significance to improve the performance and reliability of new energy vehicles.
