Introducing the charged ER Series SAE J1772

Reliable, Efficient EV Charging System for Any Environment: The ER Series SAE J1772

Amphenol Industrial Operations has introduced the ER Series SAE J1772 AC charging cable and inlet, an advanced solution designed for electric vehicles (EVs), hybrid-electric vehicles, and other e-mobility applications. This new connector series is compliant with SAE J1772 standards for AC Level 1 and Level 2 EV charging systems, addressing the rapidly growing demand for reliable and efficient charging solutions in both personal and commercial markets.

As the global electric vehicle market continues to expand, the need for versatile charging infrastructure becomes more critical. The ER Series is designed to accommodate a wide range of applications, from residential charging setups to commercial electric vehicle supply equipment (EVSE) installations. The cable can handle up to 250V AC and support current ratings up to 80 amps, making it suitable for a variety of charging speeds, whether for slow, overnight charging or faster, high-capacity charging stations. This adaptability ensures that the ER Series can meet the needs of electric buses, trucks, delivery vehicles, and personal EVs alike.

Ease of use is a key design feature of the ER Series. The connector is built with an ergonomic handle, making it easy to plug in and remove. The system’s low insertion/withdrawal force, rated at less than 75 Newtons, ensures smooth operation, reducing wear and tear on the connector and the vehicle’s inlet. This is particularly important for everyday users, who need a charging system that is both intuitive and durable. Additionally, the ER Series is rated for over 10,000 mating cycles, guaranteeing long-term reliability even with frequent use. The connector’s performance is further enhanced by Amphenol’s proprietary contact and plating technologies, which minimize temperature rise and reduce contact resistance. These technologies help ensure safer charging while extending the lifespan of the system.

One of the most significant benefits of the ER Series is its rugged and environmentally resistant design. The connector is rated IP67, meaning it is dustproof and waterproof, offering reliable performance even in challenging conditions. The ER Series is also protected by a Type 3S rating, which makes it resistant to ice buildup and capable of functioning in subzero temperatures. This durability makes the ER Series a dependable choice for users in regions with harsh winters or extreme weather conditions. With an operating temperature range of -30°C to +50°C, the connector is designed to function reliably across a broad range of environments, while its components can withstand even more extreme temperatures during storage and transport.

The ER Series SAE J1772 supports two different charging modes, adding to its versatility. Mode 2 charging is a portable solution, allowing users to charge their vehicles from a standard household socket or an industrial CEE socket with the appropriate cable. This option is convenient for individual users who need flexibility in where they charge their vehicles. Mode 3, on the other hand, is designed for use with dedicated charging stations or home-mounted wall boxes. This mode offers controlled charging, where the vehicle communicates with the charger to determine the appropriate current before voltage is supplied. This not only ensures a safe and efficient charging process but also provides greater peace of mind for users.

Built to endure tough environments, the ER Series SAE J1772 can withstand up to 96 hours of salt spray exposure, making it especially well-suited for industrial and heavy-duty applications. In locations where equipment is exposed to corrosive conditions, such as coastal areas or areas with high pollution, the connector’s durable design helps prevent damage, extending its operational life. The system is engineered to protect both the connector and the vehicle’s inlet from premature wear, ensuring a long-lasting, reliable connection even in demanding environments.

Amphenol Industrial Operations has long been recognized for its leadership in high-performance interconnect systems, and the ER Series SAE J1772 solidifies that reputation. By offering a cost-effective, dependable solution for EV charging, Amphenol is meeting the needs of a rapidly expanding market. The ER Series SAE J1772 combines ease of use, durability, and high performance, positioning it as a key advancement in EV charging technology. Whether for individual consumers or large-scale commercial operations, the ER Series delivers a solution that meets the demands of today’s EV market.
