The purpose of the power distribution center in a vehicle is to distribute electrical power to various components. This central hub manages the supply of electrical energy from the battery and alternator to different systems throughout the vehicle, including lighting, infotainment, and various electronic control units. By organizing and directing power effectively, it ensures that each component receives the appropriate voltage and current for proper operation.

While components like the alternator are responsible for charging the battery, and other systems may aid in starting the engine or regulating temperature, the specific function of the power distribution center is to facilitate the efficient routing of power, making it a critical component for the overall electrical system architecture of the vehicle.
