Keysight Technologies has expanded its high-power automated test equipment (ATE) portfolio with additional voltage and current options for testing electric vehicle (EV) batteries, charging systems and power conversion equipment. The expansion includes regenerative power supplies, electronic loads and a new family of dc power supplies delivering up to 12 kW.
The new configurations extend voltage coverage to 1,500 V for high-voltage battery modules and power converters. At the lower end of the range, 10-V models provide source currents up to 1,020 A for power-stage characterization and burn-in testing.
The regenerative power supplies and electronic loads deliver up to 6 kW in a single rack unit (1U) or 12 kW in 2U. The new dc power supplies also provide up to 12 kW in 2U, while other configurations offer up to 7.5 kW in 1U.
According to Keysight, the higher power density allows engineers to accommodate two to three times as many test channels within the same rack space compared with previous systems. Regenerative operation also enables absorbed power to be recovered during testing.
The expanded portfolio integrates with Keysight’s PathWave Advanced Power Control and Analysis software and PathWave Advanced Battery Test and Emulation software. These tools provide automated test configuration and data analysis, reducing the need for custom programming.
The additions build on Keysight’s high-power ATE portfolio introduced in November 2025, including 5-kW and 7.5-kW power supplies released earlier this year. The 7.5-kW models offer voltage ratings up to 1,500 V and can be connected in parallel, with up to 12 units delivering a combined 90 kW.
