Abstract

A security apparatus for an energy storage system is provided. The security apparatus includes a sensor input unit receiving security state information including door opening and closing and locking/unlocking from a door opening and closing sensor and a locking/unlocking sensor; a human machine interface (HMI) unit receiving information from a user or showing the information to the user; and a security state machine allowing manipulation of the energy storage system depending on whether security state information obtained through the sensor input unit satisfies a security state condition having a plurality of procedures in order.

Claims

1. A security apparatus for an energy storage system, the security apparatus comprising:

a sensor input unit receiving security state information comprising door opening and closing and locking/unlocking from a door opening and closing sensor and a locking/unlocking sensor;

a human machine interface (HMI) unit receiving information from a user or showing the information to the user; and

a security state machine allowing manipulation of the energy storage system depending on whether security state information obtained through the sensor input unit satisfies a security state condition having a plurality of procedures in order.

2. The security apparatus according to claim 1, wherein the security state machine operates in a plurality of security state modes comprising a user mode performing general fundamental operations of the energy storage system, a manager mode for opening a door for a regular inspection or management of the energy storage system, and an error mode in which an alarm measure is performed when arbitrary/malicious manipulation is recognized,

switch conditions between the plurality of security state modes comprises a user mode-manager mode switch condition, a user mode-error mode switch condition, a manager mode-user mode switch condition, a manager mode-error mode switch condition, and an error mode-user mode switch condition.

3. The security apparatus according to claim 2, wherein the user mode-manager mode switch condition corresponds to switching from a user mode state to a manager mode through the HMI unit, unlocking a door handle and opening a door in order, and the security state machine switches from the user mode to the manager mode when the user mode-manager mode switch condition is satisfied.

4. The security apparatus according to claim 2, wherein the user mode-error mode switch condition is configured to correspond to any one of:

switching to the manager mode through the HMI unit and opening a door in a locked state;

unlocking without a switch to the manager mode through the HMI unit;

or

opening the door without a switch to the manager mode through the HMI unit, and

the security state machine switches from the user mode to the error mode when the user mode-error mode switch condition is satisfied.

5. The security apparatus according to claim 2, wherein the manager mode-user mode switch condition corresponds to closing a door, locking a door handle and then switching to the user mode through the HMI unit, and

the security state machine switches from the manager mode to the user mode when the manager mode-user mode switch condition is satisfied.

6. The security apparatus according to claim 2, wherein the manager mode-user mode switch condition corresponds to closing a door and locking a door handle in order, and

the security state machine switches from the manager mode to the user mode after a predefined time elapses, when the manager mode-user mode switch condition is satisfied.

7. The security apparatus according to claim 2, wherein the manager mode-error mode switch condition corresponds to restoring to the user mode through the HMI unit in an unlocked state or door open state, and

the security state machine switches from the manager mode to the error mode when the manager mode-error mode switch condition is satisfied.

8. The security apparatus according to claim 2, wherein the error mode-user mode switch condition corresponds to closing a door, locking a door handle and then switching to the user mode through the HMI unit in order, and

the security state machine switches from the error mode to the user mode when the error mode-user mode switch condition is satisfied.

9. The security apparatus according to claim 1, wherein the door opening and closing sensor comprises a camera sensor, and

the camera sensor performs an image capturing operation when a door opens.

10. A method of operating a security apparatus for an energy storage system, the method comprising:

obtaining security state information comprising door opening and closing and locking/unlocking from a door opening and closing sensor and a locking/unlocking sensor; and

allowing manipulation of the energy storage system depending on whether obtained security state information satisfies a security state condition having a plurality of procedures in order.

11. The method according to claim 10, wherein allowing the manipulation of the energy storage system comprises switching between a plurality of security state modes comprising a user mode performing general fundamental operations of the energy storage system, a manager mode for opening a door for a regular inspection or management of the energy storage system, and an error mode in which an alarm measure is performed when arbitrary/malicious manipulation is recognized,

a switch conditions between the plurality of security state modes comprises a user mode-manager mode switch condition, a user mode-error mode switch condition, a manager mode-user mode switch condition, a manager mode-error mode switch condition, and an error mode-user mode switch condition.

12. The method according to claim 11, wherein the user mode-manager mode switch condition corresponds to switching from a user mode state to a manager mode through a user input, unlocking a door handle and opening a door in order, and

allowing the manipulation of the energy storage system comprises switching from the user mode to the manager mode when the user mode-manager mode switch condition is satisfied.

13. The method according to claim 11, wherein the user mode-error mode switch condition is configured to correspond to any one of:

switching to the manager mode through a user input and opening a door in a locked state;

unlocking without a switch to the manager mode through the user input;

or

opening the door without a switch to the manager mode through the user input, and

allowing the manipulation of the energy storage system comprises switching from the user mode to the error mode when the user mode-error mode switch condition is satisfied.

14. The method according to claim 11, wherein the manager mode-user mode switch condition corresponds to closing a door, locking a door handle and then switching to the user mode through the HMI unit, and

allowing the manipulation of the energy storage system comprises switching from the manager mode to the user mode when the manager mode-user mode switch condition is satisfied.

15. The method according to claim 11, wherein the manager mode-user mode switch condition corresponds to closing a door and locking a door handle in order, and

allowing the manipulation of the energy storage system comprises switching from the manager mode to the user mode when the manager mode-user mode switch condition is satisfied.
