EA Elektro-Automatik, a manufacturer of DC programmable power supplies, bidirectional power supplies and regenerative electronic loads, has unveiled a compact, automated battery cycler and test system designed to enable manufacturers to better test EV batteries as the industry evolves to higher-power technologies.

The 10300 Series ATE system offers 300 kW of power in a single 42U-high rack that requires only 6.5 square feet of floor space. Users may parallel racks for up to 3.84 MW of testing capability.

The new series offers 2,000 VDC capacity for testing high-voltage battery packs. Each rack can supply and sink up to 2,400 A per rack, and the system offers up to 30,720 A total capacity. This facilitates battery pulse testing, which may require exponentially higher current than the battery AH rating.

In addition to battery cycling, tests include drive cycle simulations and insulation resistance. The test system can control an environmental chamber and communicate with a battery management system through the CAN bus interface.

Included drag-and-drop system software enables quick and easy test setup and execution.

“As consumers demand EV batteries with higher storage capacities, producers need test systems with higher power capability,” said Eric Turner, Americas Director of EA Elektro-Automatik. “Voltage levels as a result are increasing—in some cases, power grid batteries need to be tested now at 1,500 volts. The introduction of the 10300 Series means there is now a production battery test system that is capable of meeting emerging voltage and power demands.”
