Abstract
A high voltage high current (HVHC) battery testing system (BTS) is provided that has a plurality of HVHC channels for testing multiple batteries simultaneously, where each HVHC channel provides programmed current, voltage or power, and where each HVHC channel is configured to test multiple batteries connected in a series configuration simultaneously. A low voltage low current (LVLC) BTS has a plurality of LVLC channels, where an LVLC channel is connected to each of the batteries or to each group of the batteries in a parallel configuration. Each LVLC channel provides programmed current, voltage or power according to a preloaded schedule or to a command from a control unit. The LVLCBTS is configured to provide measurement, storage and transfer of test data according to a programmed schedule. The HVHCBTS and the LVLCBTS are configured to pass current through each battery simultaneously, where the current passed through each battery by the LVLCBTS is less than 10% of the current passed through each battery by the HVHCBTS.
