Abstract: A power supply may include an AC to DC converter coupled to an AC power source to generate a DC power output, an AC port(s) to supply AC power to a respective AC load(s), an AC relay(s) coupling a respective AC port(s) to the AC power source, a DC port(s) to supply DC power to a respective DC load(s), a DC to DC converter(s) coupling the DC power output to the DC port(s), a battery(ies) coupled to the DC power output, and an ethernet port(s) to provide wired network connectivity. A controller may be configured to switch the DC port(s) between the DC power output and the battery(ies) responsive to AC power source outages, cause the AC relay(s) to cycle AC power to the AC port(s) and respective AC load(s), and cause the DC to DC converter(s) to cycle power to the DC port(s) and respective DC load(s).

Abstract: A battery monitoring system is for a battery string(s) at a geographical location, where the battery string(s) includes a plurality of series-connected batteries. The system may include wireless battery monitors each associated with a respective battery, a wireless string monitor associated with the battery string(s), and a wireless access point for communicating with the wireless battery monitors and the wireless string monitor at the location.

Abstract: A DC UPS may include a battery power source, an AC-DC converter configured to convert a grid AC power signal to a first DC power signal, and a first switch coupled downstream from the AC-DC converter. The DC UPS may include a second switch coupled between the first switch and a battery power source, and a DC-DC converter coupled to the first switch and configured to convert the battery DC power signal or the first DC power signal to a second DC power signal. The DC UPS may include first DC outputs coupled to the first switch and configured to provide the battery DC power signal or the first DC power signal to corresponding first loads, second DC outputs coupled downstream from the DC-DC converter and configured to provide the second DC power signal to corresponding second loads, and a controller.

Abstract: A UPS system may include a DC UPS having first DC outputs coupled to a first switch and configured to provide a battery DC power signal or a first DC power signal to corresponding first loads, first load controllers each coupled between respective ones of the first DC outputs and the first switch, and a controller coupled to the first switch and a second switch, and the first load controllers. The controller may be configured to switch between a first mode where the first DC power signal is supplied to the first load controllers, and a second mode where the battery DC power signal is supplied to the first load controllers. The UPS system may include a cloud application server in communication with the DC UPS and configured to cause the controller to disable and enable the first load controllers.

Abstract: A fleet management system for vehicles and batteries at a geographical location may include vehicle identification devices each associated with a corresponding vehicle at the geographical location. The system may also include wireless battery monitors at the geographical location associated with the batteries. Each of the wireless battery monitors may be configured to, when the associated battery is connected to a vehicle, during a discharge cycle, communicate with the vehicle identification device associated with the vehicle to collect a vehicle identifier associated with the vehicle identification device, and store battery activity records for the associated battery along with the vehicle identifier.
