According to reporting at EngineerLive, ITT Interconnect Solutions claims to have achieved "an industry first" with its J1772 connector for electric vehicle charging applications. ITT says the connector is capable of performing Level I and II charging from a low end of 15A/120V to a high end range of 75A/240V through the same interface.
ITT global marketing director Keith Teichmann comments: "With the release of the SAE J1772 specification in January 2010 as the standard adopted in the USA and Japan for Level I and II electric vehicle charging, robust coupler and inlet connectors capable of passing stringent testing to UL 2251 for agency approval were urgently needed to support electric vehicle production capability currently scheduled for Q4 2010. Our new interconnect is based on a high-power system used on hybrid busses: over 33,000 such interconnects are currently in service without a single known field failure."

Based on HEP spring contact technology, the new connectors are said to represent the industry's first UL-rated, J1772 Level II 75A four-hour-or-less full charging connectors. Charging options include 75A/240V, 30A/240V, 15A/240V and 15A/120V. The inlet connector includes finger-tip protection on the power and ground pin contacts, as well as an enhanced cable management system using ITT's VEAM CIR series backshells. By using cable with a greater degree of flexibility, ease-of-use is assured on charging units with a retractable cable, says ITT.
The UL-approved J1772 Level I and II electric vehicle charging robust coupler and inlet connectors are suitable for electric passenger vehicles, home charging units, public infrastructure charging units, roadside assistance trucks, electric fleet vehicles, and electric motorcycles.
