Tektronix business unit, EA Elektro-Automatik (EA), a global provider of dc programmable power supplies and bidirectional power supplies, announced an enhanced EA BTS 10300 Battery Test System.
The EA BTS 10300 provides unparalleled power density, offering 300 kW in a single 42U-high rack and occupying only 6.5 square feet of production floor space. This compact, automated battery cycler and test system is a direct response to the pressing challenges faced by manufacturers in testing electric vehicle (EV) batteries efficiently and effectively.
This compact EV battery test rack is a game-changer, providing substantial power in minimal space, a crucial benefit for the production EV battery test market. Its ability to parallel racks for a massive 3.84 MW of testing capability underscores its scalability and efficiency.
Boasting an unparalleled 2000-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 BTS 10300 high-current capability is essential for rigorous battery module tests and battery cell tests, including pulse testing that demands exponentially higher currents.
Previously, achieving such performance required a costly, custom-built system. Now, the 10300 Series delivers this high-level functionality as a complete COTS turnkey solution, encompassing battery cycling, drive cycle simulations, insulation resistance tests, and more.
Innovative operation and testing advantages
Featuring EA Elektro-Automatik’s bidirectional power supply with SiC-based switching, the EA BTS 10300 offers efficient and rapid operation. This system not only reduces electrical costs by regenerating power back to the grid with up to 96.5% efficiency but also minimizes HVAC expenses due to its low heat generation.
With system slew rates at least twice as fast as competitors and fast data acquisition rates of up to 1.5 kHz, it ensures precise and comprehensive EV battery testing.
Future-proof testing with autoranging
The EA BTS 10300’s true autoranging capability sets it apart, allowing for a wide range of voltage and current adjustments without interrupting the test cycle.
This feature is especially beneficial for adaptive testing requirements, making it a future-proof investment for evolving high-voltage EV battery test needs.
