Supplying DC Input Power for HEV Testing
Application Notes
Test Challenges
Hybrid electric vehicle (HEV) and electric vehicle (EV) test starts with a reliable and stable DC voltage in the range of a few kW to many tens of kW. High-power batteries, fast chargers, DC/DC converters, and battery electronic control units all require many kW of power during test at various voltage and current combinations. At these high power levels, protecting the device under test (DUT) is also very important.
Solution
Keysight Technologies, Inc. N8900 power supplies’ autoranging output characteristic covers more voltage and current combinations. Use one power supply for high voltage/low current or low voltage/high current. Built-in voltage, current, and power measurements monitor HEV/EV DUT power consumption and built-in protection keeps the DUT safe during test.
