The power conversion section of Electric and Plug-in Hybrid vehicle (EV/PHEV) systems are composed of several power electronic units, which include the EVSE (EV Supply Equipment), on-board charger, DC/DC converter, motor driver, and more. EV/PHEV power systems are often custom-built and designed specifically for certain power electronic units. These systems are usually difficult to maintain and lack flexibility once the design is finalized, and these shortcomings will definitely impede the product development process as test methodologies evolve.

Automatic Test System - Chroma 8000
The Chroma 8000 ATS is a standard test platform that solves the conventional problem of self designed ATS’s for power electronics testing. It is built on testing technology and experience in the power electronics industry, where Chroma has been a technological leader for more than 30 years. Chroma has provided over 2,000 Chroma 8000 ATS's to customers worldwide that are being used in R&D, QA departments and production lines. Our test system is designed to have an open architecture, allowing the user to easily integrate various instruments. The Chroma 8000 ATS includes a wide range of hardware choices such as AC/DC power supplies, Electronic Loads, Power analyzers, Oscilloscopes, Digital multi-meters, as well as various digital/analog I/ O cards. This flexibility combined with an open architecture gives the user an adaptable, powerful and cost effective test system for the EV/HEV power electronics. The Chroma 8000 test system includes a sophisticated test executive, which includes pre-written test items. Users may also create new test items by using the test item editor function. This provides the flexibility to expand your test library without limits. The Chroma 8000 ATS’s ability to satisfying the test requirements for multiple power electronic units is key to keeping consistency and reducing costs during the transition between R&D and production.
Software Platform of ATS Chroma 8000 PowerPro III
PowerPro III provides users with an open software architecture suited to a wide range of applications and devices. It allows users to define test procedures, test condition variables, test result variables and temporary variables. The unique report wizard allows users to integrate different types of document presentations, like tabular test data, DSO waveform and correlation charts in M/S Word format. The Statistic function provides off-the-shelf statistical reporting tools. All the test conditions defined in the test program as well as the test readings can be stored and analyzed by the statistic report function.
Power Pro III runs under the Windows 2000/XP/7 operating environment, providing the test engineer a dedicated test system with easy access to Windows resources.

Customized Test Fixtures
The test fixture, a device that interfaces between the ATS and the UUT, is a necessary for EV/HEV power electronics unit testing. Due to the different form factors and various connector types, it is impossible to find an off the shelf test fixture that can fit all testing requirements. The Chroma 8000 ATS support team not only helps to plan and develop the ATS, but they also provide their expertise to tailor a test fixture to the customer's needs.
Electrical Safety Test
Electrical safety test is the most important for electric vehicles as persistent electrical quality is requisite for the drivers that have to drive the cars everyday. For the environment the electric vehicles are in use, the application of electrical safety covers the power system, the charging system, the power wiring, the charging line, the charging connector and the charging station, etc.
Standards ☑ Isolation resistance Test (ISO 6469-1, GB/T 18384-1) ☑ Withstand voltage test (ISO 6469-3, GB/T 18384-3) ☑ Continuity test for potential equalization (ISO 6469-3, GB/T 18384-3) ☑ Related standards : UL 2202, UL 2251, ECE R100, UL 2580, GB 18488
Customized ATS for EV/PHEV Maintenance Application
The demand for charging stations is steadily growing as EV/PHEV's gain popularity. Unlike the conventional gas station, which mainly consists of mechanical parts, the EV/PHEV charging station has Implemented sophisticated electronics for metering, controlling, and measuring the amount of energy required and transferred to the vehicle.
With the powertrain system switching from internal combustion engine (ICE) mechanical design to fully electric powertrain design, ICE oriented auto mechanics must quickly familiarize themselves with the electrified system.
In order to provide optimum vehicle operating condition, maintain serviceability and minimize the chance of a mechanics exposure to electric shock hazards, the Chroma 8000 provides unique, dynamic diagnostic capabilities. These include: vehicle battery unit testing, voltage/current parameter measurement reading, CAN bus interface, diagnostic reporting, etc. The test system provides diagnostic data through the internet directly to the vehicle manufacturer for data analysis.
