Webasto’s 900 EX Power Bridge links two battery test units to reach 1,500 V

Labs that run Webasto’s 900 EX battery test units can now push them to higher voltages without buying new hardware. The company’s new 900 EX Power Bridge ties two units together into a single system rated to 1,500 V and 500 kW.

The Power Bridge is built to work with the existing 900 EX, combining two units so a single setup can test higher-voltage batteries and energy storage architectures. Webasto says the approach raises voltage and power without adding complexity to control, calibration or service, and that it reuses infrastructure customers already run so the test environment keeps the same look, feel and function.

Battery test systems have to match the voltage and power of the packs they cycle, and pairing two 900 EX units gives a lab a route to 1,500 V testing on equipment it already owns.

“The 900 EX Power Bridge represents a major step forward for users looking to scale their battery testing capabilities without disrupting existing test setups,” said Dimitri Liambotis, Sales Manager of Power Test Systems at Webasto.

Excel Engineering, an independent laboratory that validates electrical and energy storage systems across automotive, off-road, rail, marine and stationary markets, has used the Power Bridge to expand its high-voltage test offering. The lab had faced rising demand for 1,500 V platform testing.

“This solution allowed us to meet the needs of our customers in a timely manner, which is paramount,” said Matt Sobotka, General Manager of Electrification Testing at Excel Engineering. “The controlability, ease of use, and install of the 900 EX are unmatched in the industry. Projects often require high-frequency controls, which we have been able to achieve with this setup.”
