According to one aspect, embodiments of the invention provide a power system comprising an input power distribution circuit including a plurality of power connections, a first power supply coupled to a first power connection of the plurality of power connections, a scalable battery bank including at least a first battery module coupled to a second power connection of the plurality of power connections, the first battery module including a first battery and a first battery charger, the first battery charger and the first power supply being removable and interchangeable, and an output power distribution circuit coupled to the first power supply and the first battery and configured to provide output power derived from at least one of the first power supply and the first battery.

System and method for power storage and distribution

According to at least one aspect, embodiments herein provide a traffic light power management system comprising a power source, a first output, a service bypass unit and a power management unit. The service bypass unit is configured to receive AC power from the power source, convert the AC power to a first DC power in a first mode of operation, provide the first DC power to the first output in the first mode of operation, and provide the AC power to a power management unit in a second mode of operation. The power management unit is coupled to the service bypass unit, and is configured to receive the AC power from the service bypass unit in the second mode of operation, convert the AC power to a second DC power in the second mode of operation, and provide the DC power to the first output in the second mode of operation.
