Chroma test gear to be used by EV maker Mission Motors

Electric motorcycle manufacturer Mission Motors has named test equipment and systems maker Chroma Systems Solutions an official equipment sponsor.

What this means is that Chroma’s power test equipment and software will be used by Mission Motors to test its EV battery modules. The cornerstone of Mission’s technology, a lithium-ion battery pack, relies on rigorous testing to determine performance and lifetime characteristics, according to the manufacturer.

Mission Motors chose Chroma’s 63208 DC Electronic Load. The 63208 is capable of pulling a 15.6kW continuous load from their battery modules -- reportedly enough power to propel the Mission R race bike at a continuous 80 mph.

“Mission’s is the first equipment sponsorship for Chroma Systems Solutions,” says Steve Grodt, Chroma marketing executive. “Having promotional access to the Mission R electric racing bike is something to get excited about."

Mission uses Chroma’s 63208 Electronic Load as a research tool. To achieve their specifications, tests must characterize electrical and thermal characteristics throughout a module’s lifetime.

Mission uses power vs. time profiles from their vehicles to simulate true automotive power loads. Chroma’s software reportedly allows Mission to take these loads and test their modules on the bench as though they were in a Mission vehicle.

When not being used for R&D, the Chroma load acts as a qualification tester in Mission module production. It first verifies each module's capacity with a constant rate 1C discharge. If a module’s energy capacity passes this test, it is then tested for power capability. At three different states of charge, Mission pulse tests each module to verify that it will meet its performance requirements. These tests are done at roughly 14 kW loads.

“We've been using the Chroma 63208 Electronic DC Load for a number of applications,” says Edward West, Mission’s president. “The unit has been very intuitive and easy to use. More importantly, it has saved us a tremendous amount of time and has improved our data collection methodology.”
