Press Release: USCAR'S EWCAP UPDATES USCAR-21 CRIMP PERFORMANCE SPEC TO ADDRESS HIGHER ELECTRICAL LOADS IN VEHICLES

SOUTHFIELD, Mich., Dec. 4, 2014 – Continuing its work in advancing new automotive technologies, the Electrical Wiring Component Applications Partnership (EWCAP) recently updated its USCAR-21 Crimp Performance Specification to address the higher loads of increasingly electrified vehicles.

The new test performance limits were engineered so the specification now applies to the higher duty cycles of electric vehicles and vehicles with continuously-operated high power electrical devices.

The USCAR-21 Crimp Performance Specification calls-out a testing sequence that simulates what a crimp will experience throughout the life of a vehicle, estimated at approximately 15 years. It is composed of a series of tests completed in two phases: thermal shock and high-humidity steam aging.

Through USCAR’s EWCAP, Chrysler Group LLC, Ford Motor Company and General Motors provided feedback to update and advance an already broadly-accepted specification for use in more applications, providing suppliers confidence the USCAR test will be valid across the entire OEM base.

“Prior to implementation of the initial USCAR-21 specification in 2002, each OEM had its own crimp test procedure.  USCAR-21 allowed one set of standardized tests across the OEMs, improving efficacy and quality,” said EWCAP Collaborative Research Leader Don Price. “USCAR-21 substantially reduced testing time, cost and improved quality.”

Now, the update will assure that this success continues as the industry makes increasingly electrified vehicles. This update and a companion update to USCAR-37, specific to high voltage, assures that even high-power and high-duty cycle applications will achieve optimal performance.

The USCAR-21 update has been submitted to SAE for publication and approval is anticipated by the end of 2014.

EWCAP is part of USCAR, whose members are Chrysler Group, Ford and GM. Since 1994, EWCAP has been developing and releasing automotive wiring and connector specifications that typically become published for the U.S. auto industry by SAE International.
