Tektronix business unit, EA Elektro-Automatik (EA) has introduced an enhanced EA BTS 10300 battery test system for testing electric-vehicle (EV) batteries. The company claims the new battery tester delivers industry-leading high-voltage capacity and power density of 300 kW in a single 42U-high rack, requiring only 6.5 square feet of floor space.
With a 2,000 VDC capacity for high-voltage EV battery tests, the EA BTS 10300 can supply and sink up to 2,400 A per rack, reaching a total capacity of up to 30,720 A. The test system’s high-current capability is needed for stringent battery module tests and battery cell tests, including pulse testing which demands exponentially higher currents.
Previously, it would require a costly, custom-built system to meet these requirements, EA said. With the 10300 Series, it offers high-level functionality as a complete COTS turnkey solution, encompassing a range of features including battery cycling, drive cycle simulations and insulation resistance tests.
The compact EA BTS 10300 automated battery cycler and test system is designed to meet the evolving demand for higher power battery technologies in the EV industry. Called a future-proof investment with high-voltage capabilities and autoranging, the battery test system also offers cost and space savings. The autoranging capability allows for a wide range of voltage and current adjustments without interrupting the test cycle, EA said.
“The EA BTS 10300 battery test system represents a leap in testing technology, offering significant cost and space savings while being environmentally friendly,” said Russ Gaubatz, senior applications engineer, EA Elektro-Automatik, in a statement. “Its power regeneration and efficient operation cut electrical and HVAC costs, and its compact design requires only a third of the floor space compared to competitors.”
EA said the new battery test system is achieving new standards in the EV battery test arena and is a game changer by providing substantial power in minimal space. It also is scalable with the capability to parallel racks for 3.84 MW of testing capability and offers the ability to adjust test ranges seamlessly.
The EA BTS 10300 features the company’s bidirectional power supply with silicon-carbide-based switching. This battery test system reduces electrical costs by regenerating power back to the grid with up to 96.5% efficiency and minimizes HVAC expenses due to its low heat generation, EA said. The company also claims system slew rates of at least twice as fast as competitors and fast data acquisition rates of up to 1.5 kHz for precise and comprehensive EV battery testing.
The EA BTS 10300 battery test system is currently available in the U.S. and Canada. The system also provides customizable HMI and data reporting.
