As the global EV charging infrastructure rapidly scales, long-term durability has become a key differentiator for high-power DC charging products. At Workersbee, we're proud to announce that our European Standard DC 2.0 charging connector (200A) has successfully passed a 30,000-cycle plug/unplug durability test with outstanding thermal performance, even under extreme environmental conditions.

This third-party testing, conducted by Suzhou Sunchuang Energy Testing & Certification Co., Ltd., confirms that Workersbee's DC 2.0 connector isn't just built for performance—it's built to endure.

A New Benchmark for Durability in DC Charging

The testing process wasn't easy. Over more than 40 days, our product underwent:

30,000 plug/unplug cycles, including salt-mud contamination steps

Five rounds of 24-hour powered environmental stress at -40°C to +85°C, 95% humidity

Real-time temperature rise monitoring using 70mm² high-current cables

Mid-test design enhancement with added heat dissipation holes after 24,000 cycles

Despite these intense conditions, the connector's temperature rise never exceeded 50K, staying well within industry safety limits. The highest recorded temperature rise was just 41.3K at 30,000 cycles, proving stable performance under heavy load and prolonged use.

Why This Matters

For EV infrastructure partners, this result translates into greater long-term reliability and lower maintenance costs. Whether you operate public charging stations or supply high-power connectors for OEMs, knowing that your equipment can handle 30,000 operations without degradation is a major advantage.

"We design every connector at Workersbee with future-ready endurance in mind. This test result is more than just a certification—it's real-world proof of our commitment to safety, durability, and innovation,” said a senior engineer from the Workersbee R&D team.

Designed for Harsh Environments

The test didn't just simulate ideal conditions. We pushed the product beyond typical expectations by:

Soaking the connector in mud-salt water before testing the insertion

Powering it through extreme climate cycles

Replicating field conditions with heavy-duty 70mm² cables

This makes our DC 2.0 connector ideal for deployment in high-use public charging stations, bus depots, logistics fleets, and regions with fluctuating climates.

Workersbee: Reliable Power, Proven Performance

As one of China's leading EV charging component manufacturers, Workersbee remains committed to producing products that meet international standards and exceed customer expectations. This milestone further strengthens our portfolio of high-power charging solutions designed for Europe, North America, the Middle East, and beyond.
