The rise of New Energy Vehicles (NEVs), including Electric Vehicles (EVs), Hybrid Electric Vehicles (HEVs), and Fuel Cell Electric Vehicles (FCEVs), has fundamentally transformed the automotive industry. As the demand for eco-friendly transportation solutions continues to increase, so does the need for advanced electrical systems to power these vehicles. One of the most crucial yet often overlooked components in an NEV’s electrical system is the New Energy Vehicle Relay. This article explores the importance, types, and functions of relays in ensuring the safety, performance, and efficiency of modern electric and hybrid vehicles.
What is a New Energy Vehicle Relay? A New Energy Vehicle Relay is an electromechanical or electronic switch used to control the flow of electrical current within the vehicle’s powertrain and auxiliary systems. These relays are designed to handle the high voltage and currents that are typical in EVs and HEVs, ensuring smooth operation while maintaining safety standards. In essence, these relays control various electrical circuits in the vehicle, allowing for efficient energy management and preventing damage to sensitive components. Types of New Energy Vehicle Relays There are several types of relays used in NEVs, each serving specific functions：
