Abstract
Disclosed herein are methods, systems, and devices for supporting the transition to lithium-ion batteries and leveraging the value that lithium-ion batteries offer in double conversion uninterruptible power supply (UPS) applications. In one embodiment, a battery pack includes (1) a plurality of battery cells electrically coupled between a positive terminal and a negative terminal; (2) monitoring and control circuitry electrically coupled with the plurality of battery cells; (3) a controller electrically coupled with the monitoring and control circuitry; (4) a communication interface and electrically coupled with the communication interface; and (5) a user interface. The monitoring and control circuitry includes a plurality of integrated shunt resistors and a plurality of integrated load circuits electrically coupled with the plurality of battery cells. The monitoring and control circuitry is configured for determining a current state-of-charge (SOC) for each battery cell of the plurality of battery cells and for discharging each battery cell to a predetermined SOC.
