Keysight and Jiyun collaborate on EV battery test system

Keysight Technologies, a test and measurement technology company, is collaborating with the Chinese EV tech company Jiyun Technologies on a battery test system for EVs.

The battery test system features Keysight components, including its RPS7900-series regenerative power supply, DAQ973A Data Acquisition System and CAN bus communication interfaces. According to Keysight, the system’s regenerative power enables it “to achieve 90% power efficiency that reduces operational costs while minimizing heat dissipation, as well as reducing the associated costs of required cooling systems.”

The system can manage a maximum output voltage of 1,000 V, a current level up to 540 A and a maximum power level of 180 kW.

“In addition to collecting basic information such as battery voltage, current and thermal data, the battery management system (BMS) is also integrated into the communication structure to efficiently gather data and provide access to all parameters through a single software instance,” says Keysight. The test software is adopted from Keysight’s PathWave software.  

Keysight has delivered the system to Jiyun Technologies.

“The testing needs for electrical vehicles will pose a challenge for the foreseeable future and depending on specific customer needs, solution offerings need to be adaptable,” says China Business Manager for the Automotive and Energy Business Unit at Keysight Technologies Jian-Rui Ma. “We appreciate the opportunity and challenge to work with Jiyun Technologies to develop a solution that is tailored to their specific requirements.”
