New high-power DC emulator for EV fast charging applications

Keysight Technologies has released the enhanced Scienlab Regenerative DC Emulator (SL1800A Series), the next generation high power DC emulator for EV fast charging applications that allow customers to obtain high-power DC charging test up to 270kW in a small footprint.

Typical high-power DC test systems are large and use valuable lab floor space, and these are also inefficient, needing large amounts of energy to run the test system and to keep the lab space cool through high-power tests. When performing high-power DC fast charging tests, customers require a solution that combines the required power demands with communication tests and monitoring that is simple to set up and use.

The emulator allows customers to realistically emulate high-voltage, high-power EV batteries in charging test applications, including high-power DC fast charging, when paired with the company's SL1047A Scienlab Charging Discovery System. This solution can emulate EV batteries up to 1500V and 900A and can be paralleled to attain up to megawatts.

"Our next-generation high-power DC emulators, based on silicon-carbide technology, are greater than 96% efficient and provide more power and higher voltages in less space when compared to similar systems," said Thomas Goetzl, vice president and general manager for Keysight's Automotive and Energy Solutions business unit. "When combined with the SL1047A Charging Discovery System, it enables our customers to test all aspects of high-power DC fast charging in their lab."
