Keysight Technologies (hereafter referred to as Keysight) unveiled a next-generation emulation solution that provides high power even in tight spaces.

Keysight Technologies announced the SL1800A series, a next-generation high-power DC emulator for electric vehicle rapid charging.

This is an enhanced Scienlab regenerative DC emulator that enables customers to perform high-power DC charging tests up to 270kW in a smaller footprint.

High-power DC test systems are typically large and take up a lot of laboratory floor space.

These systems are also inefficient, consuming significant amounts of energy to run the test system and cool the laboratory during high-power tests.

Customers needed a solution that combined communication test and monitoring with the required power requirements for high-power DC fast charging testing, while being easy to set up and use.

Keysight's Scienlab regenerative DC emulator, along with the Keysight SL1047A Scienlab Charging Discovery System, enables charging tests such as high-power DC fast charging. It can realistically emulate high-voltage, high-power electric vehicle batteries in the field.

The solution can emulate EV batteries up to 1500V, up to 900A, and can parallelize up to several megawatts.

Key benefits of the Keysight SL1800A series include:

Powered by advanced SiC wide-bandgap semiconductors, the system reduces energy costs for laboratory cooling, with only 4% of the system's power lost as heat.

Additionally, the SL1800A series features a regenerative system that returns power to the grid when operating as an electronic load during EV battery emulation and charging tests, and comes in a space-saving form factor that maximizes lab space utilization.

“Based on silicon carbide technology, Keysight’s next-generation high-power DC emulator is more than 96 percent more efficient, delivers more power and voltage, and takes up less space than comparable systems,” said Thomas Goetzl, vice president and general manager of Keysight’s Automotive and Energy Solutions business unit. “When combined with the SL1047A Charging Discovery system, this emulator enables labs to test all aspects of high-power DC fast charging.”
