The High-Voltage Battery Test System (9300 Series) is a fast-acting, fully programmable, and bi-directional DC source (charge) that provides reversible current flow in order to act as a regenerative DC load (discharge). Both modes support any combination of constant power, constant voltage, and constant-current regulation limits. Products tested include batteries, fuel cells, ultra-capacitors, and other energy storage devices used in the automotive, aviation, heavy industrial, marine, grid storage, university research, and standards certification laboratory markets. The most frequent uses are for battery charge/discharge cycling, testing battery chargers and battery emulation.
