Abstract

A system, apparatus, and method are disclosed for providing electrical charge to residents of a controlled-environment facility. In an embodiment, a charging station may be provided in an area accessible to an inmate to allow charging of in an inmate smart device, such as a phone or tablet. In an embodiment, a portable charger may be provided to an inmate for charging a smart device.

Claims

1. A charging system for providing electrical charge in a controlled-environment facility, the charging system comprising:

a power source configured to deliver power to a telephone outlet via telephone wiring; and

an inmate-accessible charging station including;

power circuitry configured to receive power from the power source via a connection to the telephone outlet;

an energy repository configured to store the received energy;

a controller configured to regulate discharging of energy from the energy repository based on a threshold of remaining energy stored in the energy repository; and

an electronic device interface configured to discharge the energy stored in the energy repository to an inmate electronic device according to the regulation from the controller.

2. The charging system of claim 1, wherein the charging station further includes a photovoltaic cell configured to generate electrical energy in response to receiving light energy, and wherein the energy repository is further configured to store the generated electrical energy.

3. The charging system of claim 2, wherein the photovoltaic cell is further configured to receive light energy from an interior lighting fixture of the controlled-environment facility.

4. The charging system of claim 1, wherein the received energy stored in the energy repository energy repository is received as a trickle charge.

5. The charging system of claim 1, wherein the telephone wiring is a twisted pair.

6. The charging system of claim 1, wherein the charging station further includes an alarm configured to alert facility staff in response to a detection of inmate tampering with the charging station.

7. The charging system of claim 1, wherein the energy repository is a supercapacitor.

8. A charging station for providing electrical charge in a controlled-environment facility, the charging station comprising:

a solar panel configured to receive light energy from a controlled-environment light source;

an accumulator configured to store energy received by the solar panel;

a controller configured to regulate discharging of energy from the accumulator based on a threshold of remaining energy stored in the accumulator; and

a charging interface configured to discharge the energy stored in the accumulator to an electronic device according to the regulation from the controller.

9. The charging station of claim 8, further comprising a power interface configured to receive power from at least one of a closed circuit television outlet, an Ethernet outlet, and a television cable outlet, and wherein the accumulator is further configured to store energy received from the power interface.

10. The charging station of claim 8, further comprising a wireless power interface configured to receive wirelessly transmitted power, and wherein the accumulator is further configured to store energy received from the wireless power interface.

11. The charging station of claim 8, wherein the charging interface is further configured to wirelessly transmit power to the electronic device.

12. The charging station of claim 8, wherein the accumulator includes a supercapacitor configured to store and discharge energy.

13. The charging station of claim 8, wherein the charging interface is further configured to discharge energy stored in the accumulator to an inmate smart device and to a portable charger.

14. The charging station of claim 8, further comprising an alarm configured to alert facility staff in response to a detection of inmate tampering with the charging station.

15. A charging station for providing electrical charge in a controlled-environment facility, the charging station comprising:

an energy collector configured to receive power;

an accumulator, configured to store energy and receive power from the energy collector;

a controller configured to regulate discharging of energy from the accumulator based on a threshold of remaining energy stored in the accumulator;

a charging interface configured to discharge the energy stored in the accumulator to an electronic device according to the regulation from the controller; and

an alarm to prevent inmate tampering.

16. The charging station of claim 15, wherein the energy collector is further configured to receive power from a telephone twisted pair line.

17. The charging station of claim 15, wherein the energy collector is further configured to receive power from a photovoltaic cell configured to receive light from an interior lighting fixture of the controlled-environment facility.

18. The charging station of claim 15, wherein the power received by the energy collector is received as a trickle charge.

19. The charging station of claim 15, wherein the power received by the energy collector is received as wirelessly transmitted power.

20. The charging station of claim 15, wherein the accumulator further comprises a supercapacitor configured to store and discharge energy.
