I. Core Product: The Industry Benchmark for PTC Electric Heaters in New-Energy Commercial Vehicles

Yusheng Technology’s EW25 series PTC electric heaters—third-generation high-voltage liquid heaters—are core products specifically designed to meet the large-space heating needs of new-energy commercial vehicles. They seamlessly address both cabin heating and battery thermal management, making them ideally suited to the diverse operating conditions of new-energy buses and other commercial vehicles.

Core Technical Parameters

Core Technology Highlights

1. Efficient Temperature Control and Precise Response : Utilizing imported IGBT components and PWM stepless control technology, power control accuracy reaches ±10 W. The system can dynamically adjust power in real time based on cabin temperature and battery status, enabling rapid heating and stable temperature maintenance with fast response and low energy loss.

2. A comprehensive security protection system : It incorporates multiple safety protection mechanisms, including overcurrent, overvoltage (with a 780 V upper limit and a 420 V lower limit), short-circuit, open-circuit, and overtemperature protection, coupled with a high-voltage interlock design. From electrical dielectric isolation to real-time operational status monitoring, these measures provide all-round assurance of vehicle operational safety.

3. Structural Design Optimization The one-piece die-cast housing achieves complete physical isolation between the electrical components and the coolant, eliminating the risk of fluid leakage; the PCB is independently mounted in the lower housing to prevent damage from harness compression; the IGBT modules are directly bonded to the water-cooling channels for optimized heat dissipation, balancing thermal efficiency with component longevity, while the compact design is well-suited to the installation space of commercial vehicles.

4. Extremely adaptable to the environment : Having passed rigorous tests for vibration resistance, shock resistance, corrosion resistance, and electromagnetic interference immunity, this product is capable of handling long-haul commercial vehicle transportation under complex road conditions and harsh climatic environments. It can still start reliably in extreme cold down to -40°C, thereby ensuring the operational reliability of commercial vehicles in northern regions during winter.

II. Customization Capabilities: Precisely Aligning with OEMs’ Diverse Requirements

New-energy commercial vehicles come in a wide variety of models and operate under complex conditions, resulting in significant differences among OEMs in terms of PTC electric heater installation dimensions, power configuration, and functional integration requirements. Leveraging more than a decade of expertise in automotive thermal management, Yusheng Technology has developed End-to-end customized service system From initial concept design through to mass-production delivery, we ensure precise alignment with automaker requirements.
