Laminated Busbar for Electric Car / Automative
A laminated busbar for an electric car refers to a component used in the electrical system of the vehicle. A busbar is a metallic strip or bar that conducts electricity within a system. It serves as a central point for the distribution of electrical power to various components, such as batteries, motors, and other electronic devices. In the context of an electric car, a laminated busbar is designed to efficiently and safely distribute electrical power within the vehicle's electrical system. It can handle the high currents and voltages associated with electric vehicle powertrains. The laminated construction helps manage heat dissipation, reduces electrical losses, and provides a compact and lightweight solution.
