In the evolving world of electric vehicles (EVs), the Power Distribution Unit (PDU) and its associated relays play a critical role in the safe and efficient operation of the vehicle’s electrical system. The PDU is responsible for distributing power from the high-voltage battery to various components, ensuring smooth operations in terms of energy management, safety, and performance. Within this system, relays act as the switches that control the flow of electricity to essential parts such as the drive motor, air conditioning, and auxiliary systems.
What is a PDU in Electric Vehicles? The Power Distribution Unit (PDU) in electric vehicles is essentially the “heart” of the vehicle’s electrical architecture. It manages the distribution of high-voltage power from the battery pack to various electrical systems, such as the propulsion system, heating and cooling systems, and even auxiliary electronics. The PDU ensures that energy flows to these systems in a manner that optimizes the vehicle’s performance while maintaining safety. The PDU is a vital part of the vehicle’s high-voltage electrical system. It integrates various features like fuses, circuit breakers, and power switches that help manage and distribute the power. A typical PDU contains multiple components that work together to handle electrical load, monitor power usage, and protect critical systems from damage.
