(arrangements common to telegraphic and telephonic communication H04M) ## Abstract A system comprises a power-over-ethernet (POE) network switch; an intelligent power distribution hub and gateway (IPDHG) configured to communicate with the POE network switch; a rechargeable battery configured to be recharged by the POE network switch; and one or more low duty cycle devices configured to communicate with the IPDHG, wherein the one or more low duty cycle devices are charged by the rechargeable battery. ## Claims ### Claim 1 A system comprising: a power-over-ethernet (POE) network switch that provides energy; a controller that communicates with the POE network switch; a rechargeable battery directly connected to the POE network switch, wherein the rechargeable battery is recharged with the energy directly from the POE network switch; and a plurality of low duty cycle devices, wherein, over a first interval, the plurality of low duty cycle devices draw a peak power during activating the low duty cycle devices, wherein, over a second interval, the plurality of low duty cycle devices draw negligible power, compared with the peak power draw or no power draw, wherein each of the plurality of low duty cycle devices are configured to be separately charged via the controller, and wherein, based on if power of the rechargeable battery is sufficient to supply power simultaneously to multiple of the plurality of low duty cycle devices and power draw information about the plurality of low duty cycle devices, the controller determines (i) if the controller uses the energy directly from the rechargeable battery to the controller, then to each of the plurality of low duty cycle devices or (ii) if the controller switches to using the energy from the POE network switch to the controller, then to each of the plurality of low duty cycle devices. ### Claim 2 (depends on 1) The system of claim 1, wherein the plurality of low duty cycle devices comprise one or more non-continuous duty cycle devices. ### Claim 3 (depends on 1) The system of claim 1, wherein the POE network switch further charges one or more continuous duty cycle devices. ### Claim 4 (depends on 1) The system of claim 1, wherein the plurality of low duty cycle devices are charged by the rechargeable battery during at least one of times when the plurality of low duty cycle devices are not operating or low usage of the plurality of low duty cycle devices. ### Claim 5 (depends on 1) The system of claim 1, wherein each of the plurality of low duty cycle devices are separately and directly connected with the controller. ### Claim 6 (depends on 1) The system of claim 1, wherein the plurality of low duty cycle devices include at least one of a motor, lock, light or HVAC (heating, ventilation and air conditioning) device. ### Claim 7 (depends on 1) The system of claim 1, wherein activation of the plurality of low duty cycle devices avoids a time period when the plurality of low duty cycle devices are charged by the rechargeable battery. ### Claim 8 (depends on 1) The system of claim 1, wherein the controller is configured to obtain at least one of current, voltage, power, and energy consumption information about the plurality of low duty cycle devices. ### Claim 9 (depends on 1) The system of claim 1, wherein the controller is configured to power down the plurality of low duty cycle devices, in response to determining that the plurality of low duty cycle devices are not operating. ### Claim 10 (depends on 1) The system of claim 1, wherein the rechargeable battery is further configured to increase a power delivery capability for the low duty cycle devices to support more devices per port. ### Claim 11 (depends on 1) The system of claim 1, wherein the POE network switch is configured to recharge a battery backup. ### Claim 12 (depends on 1) The system of claim 1, wherein instantaneous power delivery to the plurality of low duty cycle devices from the rechargeable battery exceeds the capacity of the POE network switch. ### Claim 13 (depends on 1) The system of claim 1, wherein the POE network switch power supports a power requirement for one or more continuous use devices. ### Claim 14 (depends on 1) The system of claim 1, wherein a first device of the plurality of low duty cycle devices receives a recharging current and relays the recharging current to a second device of the plurality of low duty cycle devices, in response to the first device having sufficient current. ### Claim 15 (depends on 1) The system of claim 1, further configured to recharge the battery during a predetermined time interval. ### Claim 16 (depends on 1) The system of claim 1, wherein the rechargeable battery is configured to be replaced without replacing the plurality of low duty cycle devices. ### Claim 17 (depends on 1) The system of claim 1, wherein a second device of the plurality of low duty cycle devices is restricted from charging, in response to a first device of the plurality of low duty cycle devices being charged by the rechargeable battery. ### Claim 18 (depends on 1) The system of claim 1, wherein a first device of the plurality of low duty cycle devices obtains priority to be charged by the rechargeable battery, in response to the first device having a lower charge. ### Claim 19 (depends on 1) The system of claim 1, wherein the rechargeable battery comprises a power supply, a recharge port, a recharge circuit and a battery bank, wherein the POE network switch comprises a power supply, a database and a power regulation unit, and wherein the controller comprises a power regulation unit, circuitry, a continuous duty network power management unit, a continuous duty network transceiver, a non-continuous duty network power management unit and a non-continuous duty network transceiver. ### Claim 20 (depends on 1) The system of claim 1, wherein the controller is an intelligent power distribution hub and gateway (IPDHG).
