The "New Four Modernizations" Driving Market Evolution

The automotive industry is undergoing a revolutionary transformation characterized by four key trends - electrification, intelligence, connectivity, and sharing - collectively known as the "New Four Modernizations."

Electrification: The Primary Driver

Environmental regulations and fuel supply constraints have made electrification the inevitable future of the global automotive industry. This shift brings not only new R&D processes and manufacturing techniques but also entirely new automotive concepts. Unlike traditional vehicles that rely on engines, chassis, and body as core competencies, new energy vehicles focus on the "three-electric" system (battery, motor, electronic control) and intelligent equipment as key selling points.

The three-electric system enables new energy vehicles to better process large amounts of data and achieve linear control, while traditional fuel vehicles primarily rely on mechanical and hydraulic systems for vehicle control, resulting in slower dynamic response to digital commands. This makes new energy vehicles more suitable for achieving high levels of automation and intelligence.

Intelligence and Connectivity: The Future Catalyst

As automotive development extends beyond electrification, vehicles are transforming from typical mechanical products into internet-connected, high-tech electronic information products. This evolution accelerates the penetration of intelligence, connectivity, and sharing, bringing profound changes to the automotive industry.

Through the construction of vehicle-road-person-cloud collaborative interaction, automobiles are no longer limited to traditional transportation functions but can meet consumer demands for convenience, comfort, and entertainment. Autonomous driving, driver assistance, and navigation systems make travel more convenient and relaxed, while LCD displays, artificial intelligence, and cloud computing technologies make travel more interesting and functional.

Connector Classification and Applications

Low-Voltage Connectors

Operating in environments below 60V, these connectors serve traditional automotive functions including:

• Battery Management Systems (BMS)
• Air conditioning systems
• Vehicle lighting
• Power distribution and fuses
• Door and window controls
• Dashboard and instrumentation

High-Voltage Connectors

Providing 60V-380V or higher voltage transmission, primarily used in:

• Battery packs
• Power Distribution Units (PDU)
• Onboard Chargers (OBC)
• DC/DC converters
• Air conditioning compressors
• PTC heating systems
• AC/DC charging interfaces

Current mainstream technology architecture requires 15-20 pairs of high-voltage connectors per new energy vehicle. Hybrid vehicles contain approximately 25% more connectors than pure electric vehicles due to additional clutches and control units in the engine and transmission system.

High-Speed Connectors

Designed for high-frequency, high-speed signal transmission with applications in:

• Autonomous driving sensors
• Cameras and radar systems
• GPS and navigation systems
• Infotainment systems
• Vehicle-to-everything (V2X) communication
• Advanced driver assistance systems (ADAS)

Market Opportunities and Growth Trends

800V Platform Adoption

Over 20 global automotive brands have confirmed plans to launch 800V system vehicles, including:

• Porsche (800V Taycan, 2019)
• BYD (e-Platform 3.0 with 800V fast charging, 2021)
• ARCFOX (800V Alpha S, 2022)
• Hyundai, Kia, Audi, Maserati, Great Wall Motor, and GAC Aion

The transition to 800V platforms is expected to increase high-voltage connector requirements to 20-25 units per vehicle, driving significant market growth.

Connector Density Increase

New energy vehicles typically use 800-1,000 connectors per vehicle, representing a several-fold increase in value compared to traditional fuel vehicles. This dramatic increase stems from the complexity of electric powertrains and advanced electronic systems.
