EV battery test system uses regenerative technology
The Procyon Battery Test System uses a bi-directional charge/discharge regenerative power stage that returns over 93 percent of the power back to the AC mains, lowering operating costs, reducing system size and eliminating/reducing external cooling requirements.
The system also uses “fill-in-the blanks” PowerStar Test Sequencer software to facilitate test setup and operation. PowerStar offers ‘Programming without Coding’ that allows users to define the charge and drive profiles unique to their vehicles or to a particular standard. Internal resistance measurements and cell balancing can be performed as required.
The space-saving design offers a scalable solution for battery packs from 5 kW to 480 kW, with voltages from 40V to 1,500V and discharge currents up to 8,000 A. The modular, building block approach allows the system to be expanded, upgraded or repurposed for new vehicles, batteries and changing test standards. Standard battery tests include: battery balance, battery charge/discharge, battery parametics, drive simulation and internal resistance.
“Recovering the energy in the battery charge/discharge cycle utilizing our systems’ regenerative stage dramatically reduces energy costs,” said Gerard Sheehan, Intepro’s Chief Technical Officer. “It also eliminates the installation and operational costs for air- or water-cooled loads to dissipate all that energy.”
