EA Elektro-Automatik (EA), a Tektronix business unit and specialist in direct current (DC) programmable power supplies and bidirectional power supplies, has introduced the EA BTS 10300 battery test system (BTS).
The BTS is designed to address the challenges faced by manufacturers in testing electric vehicle batteries. EA says it provides 300kW in a single 42U-high rack that occupies a 6.5ft2 of production-floor space. It also has a 2000V DC capacity for high-voltage EV battery tests, supplying and sinking up to 2,400A per rack, reaching a total capacity of up to 30,720A.
This high-current capability is essential for battery module tests and battery cell tests, including pulse testing which uses higher currents.
Featuring EA’s bidirectional power supply with SiC-based switching, the EA BTS 10300 is designed to reduce electrical costs by regenerating power back to the grid and minimizing HVAC expenses due to its low heat generation, the company says.
“The EA BTS 10300 Battery Test System represents a leap in testing technology, offering significant cost and space savings while being environmentally friendly,” explained Russ Gaubatz, EA senior applications engineer.
“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. With high voltage capabilities and autoranging, it’s a futureproof investment that pays for itself by adapting to evolving testing needs.”
Further capabilities of the system include HMI and data reporting, alongside the ability to adjust test ranges.
James Hitchcock, general manager at Tektronix, added, “EA Elektro-Automatik’s EA BTS 10300 complements Tektronix’s portfolio by adding advanced battery testing capabilities, crucial for the evolving needs of the EV market.”
