Abstract
A system and method for controlling excessive charging of batteries in battery power plants and power systems. A system embodiment includes: a battery plant for supplying power to a load, and incorporates one or more of the following: a power supply, a battery string (with at least one battery), and a controller. The power supply(s) is used to charge a battery string(s) having at least one battery. The controller is coupled to the battery string(s) and the power supply(s). The controller is configured to: (1) sense whether the battery string is receiving an excess current independent of current to a load by comparing current flowing to the battery string to a preset current limit, (2) dynamically adjust the current limit to eliminate any excess current detected in the battery string if an excess current is detected, and (3) increase the current limit to charge the battery string when no excess current is detected.
