Many manufacturer offer high performances of their electronic but sometimes forgot about providing an efficient and reliable battery management. Battery is fragile and needs to be treated accordingly in discharge and recharge conditions. The purpose of this document is to provide an overview of how TSI and Flexa manage the batteries, prevent their end of life and reduce possible occurrence of thermal runaway.

  • Page 50 1.2.3 MODE 3 Discharge Discharge mode is active when energy flow is taken from the battery to the DC/AC converter (inverter) of each module. In this mode the T4S monitoring sent a voltage and current value to the Flexa module. This help in case of one module has AC input failure to take power from DC and is feed through the other module to avoid discharging the battery and assure the continuity of supply for the AC load.
