Abstract
A battery pack for an energy generation system includes a cell array of conductively interconnected power cells configured to store and discharge energy, a direct current (DC)-to-DC converter coupled to the cell array and configured to receive power from the cell array during discharging of the cell array or to output power to the cell array during charging of the cell array, a pair of output terminals coupled to the DC-to-DC converter for coupling with an external device; and an are fault detection system coupled between the DC-to-DC converter and the pair of output terminals. The are fault detection system includes a first sensor for measuring power transmitted between the DC-to-DC converter and the pair of output terminals and a controller coupled to the first sensor and configured to disable the battery pack based on a measurement of the power transmitted between the DC-to-DC converter and the output terminals.
