Challenges

In high-frequency charging environments using Type 7 interfaces(IS17017-2-7 standard)—such as public charging stations, logistics fleets, and shared-mobility operations—the compact interface and frequent mating cycles place greater demands on the current-carrying capacity, temperature-rise control, durability, and serviceability of power pins. Over time, repeated mating, environmental contamination, or operational impact may cause power pins to wear or lose performance. With conventional integrated charging-gun designs, power pins typically cannot be replaced separately. A failed power pin may therefore require replacement of the entire charging gun, increasing spare-part and maintenance costs while extending equipment downtime.

Positioning

The CHOGORI ES-CT7 is a commercial DC charging gun compliant with IS 17017-2-7. It supports continuous 100A output and provides real-time temperature feedback through a built-in thermistor. Its replaceable power pin design enables on-site servicing—from disassembly and power pin replacement to reassembly—in under two minutes, making it ideal for high-power charging applications involving electric two-wheelers, three-wheelers, and commercial fleets.

Features

Faster Charging: Continuous 100A Output
The compact structure of the Type 7 interface places greater demands on pin current-carrying capacity, contact reliability, and temperature-rise control.

Easier Maintenance: Replace Power Pins in Just 2 Minutes
The ES-CT7 features replaceable power pins that can be serviced individually on site without replacing the complete charging gun. Under standard service procedures, the entire process—from opening the housing to replacing the pins and reassembling the charging gun—can be completed within two minutes.

Reliable Design for High-Frequency Commercial Use
● The ES-CT7 offers several features designed for demanding commercial charging environments:
● 10,000 mating cycles: Suitable for public charging stations and frequently operated commercial fleets;
● IPX5 water protection: Achieved in both mated and unmated conditions;
● IPXXB finger protection: Helps prevent accidental contact with hazardous live parts when unmated;
● −25°C to 105°C operating temperature: Suitable for a wide range of environments;
● CKD: Supports local wire harness processing and assembly, helping reduce transportation costs and improve supply chain flexibility.

Applications

The ES-CT7 is designed for high-frequency, high-power commercial charging applications, particularly Type 7 charging infrastructure projects in India and other South Asian markets:
● Electric two-wheeler and three-wheeler charging;
Public and centralized charging stations;
Delivery, logistics, and shared-mobility fleets;
Logistics parks and corporate fleet-charging facilities;
Charging equipment and vehicle platforms using Type 7 interfaces.

Q

What is the mating cycle life of Chogori connectors?

A
The mating cycle life of Chogori connectors varies depending on the product series and application scenarios, ranging from 3,000 to 10,000 cycles, fully meeting the stringent durability requirements of various charging and power connection applications.

For example, the Large 2+1+5 (60A+15A+5A) connector, designed specifically for electric motorcycle battery charging and discharging applications, provides a mating cycle life of 3,000 cycles. With a robust structure and excellent vibration resistance, it is well suited for frequent battery swapping and outdoor operating environments.

The Mate60 2+1+5 (60A+15A+5A) connector extends the mating cycle life to 5,000 cycles. While maintaining stable current carrying performance, it delivers smoother and more ergonomic mating operation, significantly reducing the risk of contact fatigue during long-term use.

For higher-frequency applications, Chogori’s ES-CT6 (100A+2A) electric motorcycle charging connector achieves up to 10,000 mating cycles. Combined with wear-resistant terminals and a reinforced housing design, it ensures reliable performance in high-frequency operation scenarios such as public charging stations and battery swapping cabinets.

Behind different durability levels lies Chogori’s precise control over materials, structural design, and manufacturing processes. Every connector undergoes rigorous durability testing to ensure reliable performance. This allows customers to select the most suitable solution based on actual usage intensity, achieving the optimal balance between cost efficiency and reliability.
