Primary Business and Sector Focus

Chilye operates exclusively within the alternative energy sector, with a primary focus on the electrification of transport. Its business model is centered on the "High Voltage Connection System," which acts as the nervous system for an EVâ??s power delivery. The company manages the entire lifecycle of its products, from initial electromagnetic simulation and thermal design to high-precision injection molding and automated assembly.

The entityâ??s primary market impact is seen in its contributions to: 1. Passenger Electric Vehicles: Providing high-current connectors and distribution units for mainstream EV brands. 2. Commercial Electrification: Developing heavy-duty connectors for electric buses and logistics trucks. 3. Charging Infrastructure: Engineering the interfaces between vehicles and charging stations.

Product Portfolio and Service Offerings

1. High-Voltage Connector Systems

Chilye offers a diverse range of high-voltage connectors designed to handle voltages up to 1000V DC and currents exceeding 400A. These products are characterized by their High-Voltage Interlock (HVIL) functionality, which ensures circuit safety by disconnecting power if a connector is partially unseated. * Single-Core and Multi-Core Connectors: These are used for motor controllers, battery packs, and air conditioning compressors. * Shielding Effectiveness: The connectors utilize advanced 360-degree shielding technology to mitigate Electromagnetic Interference (EMI), which is critical for the sensitive electronic environments of autonomous and connected vehicles.

2. Power Distribution Units (PDU) and Battery Disconnect Units (BDU)

The PDU and BDU represent the intelligent "routing hubs" of the vehicleâ??s high-voltage system. Chilye designs these units to manage the flow of electricity from the battery to the inverter, DC/DC converter, and onboard charger. * Custom Integration: Chilye provides customized PDU designs that incorporate fuses, contactors, and sensors into a single, compact housing to save space and weight. * Thermal Management: Their units are engineered with high thermal conductivity materials to prevent overheating during rapid acceleration or high-speed DC charging.

3. Manual Service Disconnects (MSD)

A signature product in Chilyeâ??s catalog is the Manual Service Disconnect. This is a safety-critical component used by technicians to manually break the high-voltage circuit before performing maintenance. * Tool-Free Operation: Chilyeâ??s MSDs typically feature a dual-stage lever system to ensure the HVIL circuit is broken before the main power terminals are exposed. * Fuse Integration: Many of their MSD models include high-capacity fuses to provide overcurrent protection for the main battery circuit.

4. Charging Interface Solutions

Chilye produces vehicle-side charging inlets that comply with various international standards, including GB/T (the Chinese national standard), as well as CCS1 and CCS2 for international markets. * High-Power Charging (HPC): The company has developed liquid-cooled and high-temperature-resistant inlets capable of supporting the next generation of ultra-fast chargers. * Electronic Lock Mechanisms: Their inlets include integrated electronic locks to prevent accidental disconnection during the charging process.

5. High-Voltage Cable Assemblies

Beyond individual components, Chilye provides complete "ready-to-install" cable harnesses. These assemblies involve precision crimping and ultrasonic welding of high-voltage cables to connectors, ensuring low contact resistance and long-term durability under harsh automotive conditions such as vibration, moisture, and temperature cycling.

Manufacturing and Research Capabilities

Chilye maintains state-of-the-art manufacturing facilities that emphasize automation and environmental control. Their production lines utilize robotic assembly and 100% automated optical inspection (AOI) to ensure zero-defect quality.

The company's R&D strength lies in its specialized testing laboratories. Chilye performs in-house: * Electrical Testing: Dielectric withstand voltage, insulation resistance, and current cycling. * Mechanical Testing: Vibration, mechanical shock, and insertion/withdrawal force durability. * Environmental Testing: Salt spray, humidity, and high/low-temperature storage tests.

Strategic Market Positioning

Chilye distinguishes itself through its rapid response to the evolving 800V platform requirements. As the industry moves toward higher voltages to enable faster charging times, Chilye has been at the forefront of developing components with enhanced creepage and clearance distances and superior insulation materials. Their deep integration into the Chinese NEV ecosystemâ??serving major domestic OEMsâ??combined with TE Connectivityâ??s global reach, positions Chilye as a pivotal entity in the global shift toward sustainable mobility.
