Chroma Introduces a Compatibility Test Solution for Electric Vehicle and EV Supply Equipment (EVSE)

The media recently reported that electric vehicles cannot be charged in public locations due to incompatibility issues, some EV Supply Equipment (EVSE) installed in public locations are not provided by the manufacturer of the vehicle but by secondary manufacturers in the industry. The incompatibility arises from a lack of verification in the communication protocol resulting in a charge failure or other hazardous conditions. This could have a negative impact on the consumer’s adoption of the electric vehicle.

The common accepted global standard for electric vehicle charging is SAE J1772, which defines the technical specification requirements between the electric vehicle and EVSE.  However, it doesn’t provide a unified verification process for communication protocol in a lab approved system. Due to the variance of the manufacturer design and differences in components, the communication problems occur during actual operation resulting in an unsuccessful charge. Electric Vehicle and EVSE compatibility is imperative to consumer buy-in. However, the high costs to develop test system hardware, software and test procedures as well resource allocation has been prohibitive – until now.

Chroma has developed an Electric Vehicle AC Charging Compatibility Test System for the manufacturers of electric vehicles. This has resulted in the world’s first UL approved SAE J1772 EVSE Communication Protocol Automated Test System. The system simulates various states of an EVSE to validate AC charging compatibility before electric vehicle delivery. The solution has been adopted by a Korean electric vehicle plant and Chroma has recently acquired the bid of the Bureau of Standards, Metrology and Inspection (BSMI) as the future evaluation system of Taiwan electric vehicles. The system’s main functions are as follows:

  1. To simulate varied EVSE’s for testing if the electric vehicle can perform accurately or respond appropriately when the pilot signal contains an error; based on the requirements of different regulations.
  2. Test various EVSE communication and responses based on limits outlined in SAE J1772 standard to assure compatibility.



Chroma Contributed Award Winning Indie Short Film Selected for GI Film Festival

Chroma Systems Solutions contributed to the production of the short independent film Dog It Down in Los Angeles, California. The film, set in WWII Pearl Harbor, won Best Short Film at the 2012 Hollywood Reel Independent Film Festival and was recently announced as an official selection for the 2013 GI Film Festival (GIFF) in Washington, DC. The entire film was shot aboard the S.S. Lane Victory in San Pedro, CA. The S.S. Lane Victory served with distinction during World War II, the Korean War, and the Vietnam War.

Directed by Mark Haapala the film’s story takes place on Dec. 7, 1941. Three U.S. Navy Sailors became entombed aboard the USS West Virginia during the Japanese attack on Pearl Harbor. ‘Dogged Down’ inside an airtight storage supply room, the men managed to stay alive for 17 arduous days on the bottom of the ocean floor; living off of canned peaches and a limited water supply, before ultimately succumbing due to a lack of fresh air on Christmas Eve. Based on actual events, this story of hope and courage was written by Adriane Coros and Jim Landis. The film stars Andy Cohen, Noah Shalom and Sam Hambrecht as the three sailors.

“We are passionate about supporting the historical preservation of the men and women who gave their lives while serving in the armed forces,” said Steve Grodt, Marketing Manager at Chroma Systems Solutions. “We are proud of this film’s accolades and that it has found its way into the GI Film Festival.”

The GI Film Festival (GIFF) is a 501 c(3) non-profit educational organization dedicated to sharing the military experience in and out of the arena of war.  The festival is the first in the nation to exclusively celebrate the successes and sacrifices of the service member through the medium of film. The 2013 GIFF takes place May 6-12, Washington, DC. “Dog It Down” shows Saturday, May 11 at 9:45AM (EST). For more information please visit

Chroma and UL Sign MOU to Work on EV Testing

Dec. 11, 2012 – Lake Forest, CA: In order to promote the development of EV industry and accelerate the definition of testing standards, Chroma and the global renowned testing and certification institution UL (Underwriters Laboratories) recently signed a Memorandum of Understanding (MOU) aimed at furthering joint cooperation in propelling EV testing and standardization. Chroma also received worldwide first SAE J1772 communication protocol automatic test system (ATS) certification issued by UL.

Though only the internal combustion engine is replaced with the process of converting electricity to power for EV power source, there is a huge difference in the designing logic and testing verification. The safety and performance tests of EV related parts and equipment have to take global consistency and comprehensiveness into consideration, in which the regulations and technical specifications are relying on the internationally recognized professional entities, such as IEC, IEEE, SAE and UL for setting up. In this area of expertise, UL has been the leader for a long time.

The MOU cooperation includes joint activities in pushing EV system and test equipment solutions, exchanging expertise, building technology and capacity, as well as providing customized test lab for testing associate products/components, developing test & measurement equipment, conducting calibrations, setting up standards and delivering education and training. The first cooperation case was focused on the verification and testing of AC Electric Vehicle Supply Equipment (AC EVSE). UL used SAE J1772 standard to create a standardized comprehensive verification procedure at Taiwan Electric Research & Testing Center (TERTEC) and Chroma designed an automatic test system (Chroma 8000) to complete the performance evaluation jointly in October 2012. UL has issued worldwide first SAE J1772 communication protocol ATS certification to Chroma and the same certification to TERTEC.

To speed up the development of EV industry, Chroma is capable of providing professional test solutions for electric vehicles or hybrid electric vehicles from their more than 20 years of experience and abundant knowledge and technical skills accumulated in power electronic testing. The various AC Source/DC Power Supply/Electronic Load Chroma developed has wide range of rated power and measurement functions that can be used to test the components and equipment associated with electric vehicle or hybrid electric vehicle. Meanwhile, all of these instruments can be integrated as a multifunctional Automatic Test System (ATS) for testing EVSE (electric vehicle supply equipment, charging station), on-board charger, DC-DC converter, motor driver (inverter) and other related power electronic devices. More test solutions to comply with the regulations of EV testing will submit subsequently as the cooperation of two parties continues.
