When Safety Meets Smart Energy
In 2022, a Shenzhen-based EV charger manufacturer reported 40% fewer thermal incidents after adopting Zhongrong’s EV322-3EM-32A fuses. This 32A-rated DC fuse has become the invisible hero in China’s booming new energy vehicle market, protecting over 2 million charging piles nationwide.
Real-World Protection at Work
During summer peak hours in Hangzhou, a public charging station’s temperature soared to 55°C. The EV322-3EM-32A in a 120kW DC fast charger successfully interrupted a 180A surge caused by cooling system failure, preventing potential battery thermal runaway. “It responded within 2 milliseconds – faster than most circuit breakers,” noted the maintenance engineer.
Designed for Extreme Conditions
- Operates from -40°C to 125°C
- Withstands 1500VDC continuous operation
- IP67 protection against dust/water ingress
These specs make it ideal for outdoor charging stations. A Beijing operator reported 99.98% uptime after switching to EV322 series fuses.
Beyond EVs: Solar Storage Applications
In Jiangsu’s 50MW solar farm, 800+ EV322 units protect battery racks. “We’ve seen zero fuse-related downtime in 18 months,” confirmed the plant manager. The fuse’s arc-extinguishing design proves crucial in high-voltage DC environments.
As China targets 20% NEV penetration by 2025, components like the EV322-3EM-32A will remain critical infrastructure guardians.
