Abstract

An energy storage apparatus. The energy storage apparatus includes an energy storage, wherein the energy storage is connected to at least one energy source, wherein the energy storage is configured to store energy from the at least one energy source; a power supplier, wherein the power supplier is connected to an external load, wherein the power supplier is configured to provide energy from the energy storage to the external load; and a distribution regulator, wherein the distribution regulator is configured, in real-time, to operate the energy storage apparatus in a reduced power mode.

Claims

1. An energy storage apparatus, comprising:

an energy storage, wherein the energy storage is connected to at least one energy source, wherein the energy storage is configured to store energy from the at least one energy source;

a power supplier, wherein the power supplier is connected to an external load that is independent from any grid in that it is not connected to any grid, wherein the power supplier is configured to provide energy from the energy storage to the external load; and

a distribution regulator, wherein the distribution regulator is configured, in real-time, to operate the energy storage apparatus in a reduced power mode;

wherein the reduced power mode is a trickle power mode such that, in the trickle power mode, the energy storage apparatus stores only a minimum amount of power required to maintain at least one basic function of the energy storage apparatus.

2. The energy storage apparatus of claim 1, wherein the at least one energy source is at least one solar panel, wherein the energy stored in the energy storage is solar power.

3. The energy storage apparatus of claim 1, wherein the distribution regulator is further configured to perform at least one of:

configure the energy storage to charge to at most a first reduced charging threshold, and configure the power supplier to discharge energy from the energy storage to at least a first reduced discharging threshold.

4. The energy storage apparatus of claim 3, wherein the energy storage further includes at least one battery, wherein the first reduced charging threshold is a minimum amount of energy needed to prevent damage to the at least one battery.

5. The energy storage apparatus of claim 1, wherein the distribution regulator is further configured to:

detect an unauthorized access event, wherein the distribution regulator is configured to operate the energy storage apparatus in the reduced power mode upon detection of the unauthorized access event.

6. The energy storage apparatus of claim 5, wherein the unauthorized access event is detected based on at least one access rule and at least one of:

at least one sensor signal from at least one sensor deployed in proximity to at least a portion of the energy storage apparatus, and at least one security token.

7. The energy storage apparatus of claim 5, wherein the unauthorized access event is at least one of:

a malfunction of the energy storage apparatus, tampering of the energy storage apparatus, a power level of the energy storage below a predetermined threshold, and a payment failure.

8. The energy storage apparatus of claim 5, wherein the distribution regulator is further configured to:

determine when the unauthorized access event is over; and

upon determining that the unauthorized access event is over, configuring, in real-time, the energy storage apparatus to operate in a normal power mode, wherein at least one of an amount of energy charged and an amount of energy discharged is higher in the normal power mode than in the reduced power mode.

9. The energy storage apparatus of claim 5, wherein the distribution regulator is further configured to:

determine the reduced power mode from among a plurality of predetermined reduced power modes.

10. The energy storage apparatus of claim 9, wherein operation in the reduced power mode is determined based on a type of the detected unauthorized access event.

11. The energy storage apparatus of claim 9, wherein the energy storage further includes at least one battery, wherein operation in the reduced power mode is determined based on a power level needed for preventing damage to the at least one battery.

12. The energy storage apparatus of claim 1, wherein the energy storage apparatus further comprises:

a power manager for providing charge from the energy source to the energy storage and for providing charge from the energy storage to the power supplier.

13. An energy storage apparatus, comprising:

an energy storage, wherein the energy storage is connected to at least one energy source, wherein the energy storage is configured to store energy from the at least one energy source;

a power supplier, wherein the power supplier is connected to an external load that is independent from any grid in that it is not connected to any grid, wherein the power supplier is configured to provide energy from the energy storage to the external load; and

a distribution regulator, wherein the distribution regulator is configured, in real-time, to operate the energy storage apparatus in a reduced power mode, wherein the reduced power mode alters at least one threshold controlling charge storage of the energy storage.

14. The energy storage apparatus of claim 13, wherein the at least one threshold is a charging threshold and wherein the distribution regulator is further configured to configure the charging threshold to a first reduced charging value so that the energy storage charges to at most the first reduced charging value.

15. The energy storage apparatus of claim 14, wherein the energy storage further includes at least one battery, wherein the at least one threshold is set to no less than a minimum amount of energy needed to prevent damage to the at least one battery.

16. The energy storage apparatus of claim 13, wherein the at least one threshold is a discharging threshold and wherein the distribution regulator is further configured to set the discharging threshold to a first reduced discharging value and wherein the distribution regulator is further configured to configure the power supplier so that the power supplier discharges energy from the energy storage to at least the first reduced discharging value.

17. The energy storage apparatus of claim 13, wherein the distribution regulator is further configured to:

detect an unauthorized access event, wherein the distribution regulator is configured to operate the energy storage apparatus in the reduced power mode upon detection of the unauthorized access event.

18. The energy storage apparatus of claim 13 wherein the distribution regulator is further configured to detect an unauthorized access event and wherein a value of the at least one threshold controlling charge storage of the energy storage is set based on a type of the detected unauthorized access event.

19. The energy storage apparatus of claim 13 wherein the distribution regulator is further configured to determine when the unauthorized access event is over, and upon determining that the unauthorized access event is over, configuring, in real-time, the energy storage apparatus to operate in a normal power mode by restoring the at least one threshold to its prealteration value.
