<p>A telecommunications power system according to the invention includes a power bus and a battery module with a plurality of batteries that are connected to the power bus. A plurality of rectifier modules is connected to the power bus and usually at least one AC power source. A generator may provide backup AC power to the rectifier modules when the AC power source is interrupted. A controller includes a battery recharging control module that allows the user to select a first mode of operation that allows the generator to recharge the battery when the generator provides the backup AC power. A second mode of operation prevents the batteries from recharging when the generator provides the backup AC power. A third mode of operation decreases current provided by the generator to charge the batteries when the generator is in an overload state until the overload state ends. A fourth mode of operation prevents battery charging when the generator is in the overload state. A controller is connected to the rectifier modules and the generator and may disconnect the batteries using the contactor when a voltage of the batteries falls below a low voltage disconnect threshold when AC power is lost and/or the rectifier modules fail.</p> |
