Electric Vehicle Testing
As the automotive industry advances power conversion and battery technologies, Chroma has been actively working to improve electric vehicle (EV) testing performance and cost by developing flexible automated power conversion test platforms and regenerative battery test systems. Chroma ATE is a world leading manufacturer of precision test and measurement instrumentation, automated test systems, intelligent manufacturing systems, and turnkey test and automation solutions.
Chroma’s Automated Test Systems for Electric and Hybrid Electric Vehicles consist of standard test platforms that are combined into one expandable test system that can test most power components in an EV’s power system. Compared to specialized test equipment developed for a single EV model or application, Chroma’s systems provide greater flexibility.
The Chroma 8000 Automated Test System meets the requirements of SAE J1772 and GB/T 18487.1 for full function testing of AC level 1 and level 2 electric vehicle supply equipment (EVSE) and is built to address the testing needs of EVs’ and PHEV’s 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 (EVSE), 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 pre-written 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.
Chroma’s lithium battery automated test solutions have been successfully adopted by several well-known automotive manufacturers providing safe, real-time monitoring of the test process and reducing inspection time, significantly reducing production cost.
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.
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, as well as the charging station itself.
