As test applications increase within the EV/PHEV market, Chroma has developed a line of Automated Test Systems for Electric and Hybrid Electric Vehicle power components. Unlike specialized equipment that limits test to a single EV model, Chroma’s test systems are based on a standard test platform that seamless integrate a wide range of commercialoff- the-shelf equipment. Its broad range of use combined with PowerPro III, an open architecture software platform, the C8000 platform provides users a flexible, expandable, and cost-effective test system for engineering R&D, design validation and verification, production testing, quality assurance, and incoming inspection for most EV power components.
The Chroma 8000 Automated Test System meets the requirements of SAE J1772 for full function testing of AC level 1 and level 2 electric vehicle supply equipment and is built to address the testing needs of EVs and PHEVs from R&D to QA, production, and field service.
The system relies on Chroma’s extensive expertise in power electronics and enables seamless testing of EV supply equipment, on-board chargers, DC-to- DC converters, and motor drivers, and other power electronics. The Chroma 8000 test system can be configured with AC and DC power supplies, electronic loads, power analyzers, oscilloscopes, DMMs, as well as digital and analog I/O cards to address the requirements of multiple power electronic systems.
In addition to hardware flexibility, Chroma’s Automated Test System software includes a range of prewritten tests and the ability to create custom tests, allowing users unlimited freedom in how their products are tested. The system also provides automatic data recording and statistical report creation, giving insight into opportunities for product improvement.
This combination of configurable hardware and software enables manufacturers to reduce cost and ensure consistency through all phases of the product lifecycle.
Other EV solutions from Chroma include battery and electrical safety testing. Chroma’s battery testers are regenerative, high precision systems specifically designed for cell, module and pack level battery testing. From Charge/Discharge to Drive Cycle Simulation, Chroma’s accuracy in measurement ensures exact and reliable testing for battery incoming or outgoing inspections, as well as capacity, performance, production, and qualification testing. The cost effective regenerative feature recycles energy sourced by the battery module either back to the channels in the system or back to the grid and systems are flexible making field upgrades possible.
As always, electrical vehicle safety is of the utmost importance and compliance to several regulation standards is required. Chroma has developed many benchtop and automated test systems to test AC and DC dielectric withstand, isolation resistance, leakage current, and ground bond as well as wound component analyzers. Safety test applications include the power system, motors, batteries, charging system, wiring, charging lines and connectors, and the charging station
