New Energy Vehicle Solutions
Chauron’s Pyrofuse (Intelligent Pyrotechnic Fuse) and HVDC Fuse (High-Voltage DC Fuse) deliver ultimate safety protection for new energy vehicles (NEVs), covering 400V–800V high-voltage platforms, battery packs, motor controllers, and on-board chargers. With ultra-fast disconnection, high breaking capacity, and compact design, they safeguard the entire electrical system against short circuits, overloads, and collision impacts.
Key Technology Advantages
Ultra-fast Pyrofuse Breaking Technology
Patented Pyrofuse interrupts fault currents in 0.2 ms, much faster than the blink of an eye and far quicker than traditional thermal fuses. Provides ultimate safety protection against short circuits, collisions, and thermal runaway in EV battery packs and high-voltage systems.
Dual-trigger Intelligent Protection
Active electronic triggering via BMS or crash sensors + self-triggering by overcurrent. Ensures “break when needed, no break when not needed”, solving the conflict between normal operating current and fault protection current.
Low Power Loss & High Energy Efficiency
Extremely low internal resistance, minimal conduction loss and heat generation. Reduces energy consumption and improves system efficiency, supporting long-term stable operation of 400V/800V high-voltage platforms.
High Voltage & Large Current Withstand Capability
Products rated up to 1000 VDC, breaking capacity over 30 kA. Designed for EV main circuits, battery packs, motor controllers and charging systems, adapting to high-power and high-energy-density scenarios.
High Reliability & Long Service Life
Non-thermal operating principle, immune to surge current cumulative damage. Hermetically sealed construction, excellent shock/vibration resistance, wide temperature tolerance (–40°C to +125°C), meeting strict automotive-grade reliability requirements.
Compact & Lightweight Design
Small size, light weight, easy integration into limited EV space. Optimized structure and modular design support flexible layout and installation in battery packs and high-voltage boxes.
