When Safety Meets Innovation
Imagine a Tesla Model Y cruising on the highway suddenly encountering a battery short circuit at 120km/h. Within 0.001 seconds, the invisible guardian – Zhongrong’s EV315-L-3E-30A fuse – completes circuit breaking, preventing thermal runaway. This 30A-rated protector has become the #1 choice for 12 global EV manufacturers, including BYD and NIO, with over 5 million units deployed since 2022.
Technical Breakthroughs Redefining Safety
Designed for 1000VDC systems, the EV315-L-3E-30A achieves 98.7% faster arc extinction than traditional fuses. Its proprietary silver-alloy fuse element maintains stable resistance (-0.15% per °C) across -55°C to 125°C environments. In simulated battery pack tests, it withstood 20kA short-circuit currents – exceeding UL248-20 standards by 35%.
Real-World Protection Scenarios
- In Shanghai’s 2023 supercharge station project, 8,000 EV315 units prevented 17 thermal events
- Extended battery pack warranty periods by 2-3 years for European EV makers
- Reduced BMS false alarms by 42% in extreme temperature operations
The Data Behind Reliability
Third-party tests reveal:
| Parameter | Performance |
|---|---|
| Breaking Capacity | 200kA @ 500VDC |
| I²t Value | 0.015 A²s |
| Cycling Endurance | 100,000+ cycles |
As the EV market grows (projected $1.5T by 2030), the EV315-L-3E-30A sets new benchmarks in electrical safety through continuous innovation.
