Abstract

A battery assembly includes a power module, a receptacle connector, a driving switch and a movable stop arm. The power module includes a battery control unit and a cell electrically connected to the battery control unit. The receptacle connector is disposed at the power module and electrically connected to the cell via the battery control unit. The receptacle connector includes an insertion opening. The driving switch is disposed corresponding to the receptacle connector and electrically connected to the battery control unit. A default setting of the driving switch is “switched off”. One end of the movable stop arm is outside of the insertion opening and blocks the same. The movable stop arm is movable toward the driving switch to touch and switch on the same.

First claim

What is claimed is:

1. A battery assembly, comprising:
a power module including a battery control unit and at least one cell electrically connected to the battery control unit, the battery control unit controlling charging or discharging of the cell;
a receptacle connector disposed in the power module and electrically connected to the cell via the battery control unit for the charging or discharging of each of the cells, the receptacle connector including an insertion opening;
a driving switch disposed corresponding to the receptacle connector and electrically connected to the battery control unit, the driving switch driving the battery control unit to disconnect the electrical connection between the battery control unit and the cell when the driving switch is switched on, the driving switch being switched off in a default setting; and
a movable stop arm, one end of the movable stop arm being outside of the insertion opening and blocking the same, the movable stop arm being movable toward the driving switch to touch and switch on the driving switch.

2. The battery assembly of claim 1 , wherein the other end of the movable stop arm is fixed to the power module, so as to restrict the movable stop arm to be movable between the insertion opening and the driving switch.

3. The battery assembly of claim 1 , wherein when the driving switch is switched on, the driving switch drives the battery control unit to disconnect the electrical connection between the cell and the receptacle connector.

4. The battery assembly of claim 1 , wherein the movable stop arm is so resilient as to be restorable to its original position outside the insertion opening to block the same.

5. The battery assembly of claim 1 , wherein the battery assembly comprises plural receptacle connectors and plural driving switches, each of the receptacle connectors is electrically connected to the cell via the battery control unit, and each of the driving switches is disposed corresponding to a respective one of the receptacle connectors and electrically connected to the battery control unit.

6. An uninterruptible power supply for connection between an electronic apparatus and a main power source, the uninterruptible power supply comprising:
a power module including a battery control unit and at least one cell electrically connected to the battery control unit, the battery control unit controlling charging or discharging of the cell;
a receptacle connector disposed at the power module and electrically connected to the cell via the battery control unit for the charging or discharging of each of the cells, the receptacle connector including an insertion opening;
a driving switch disposed corresponding to the receptacle connector and electrically connected to the battery control unit, the battery control unit being driven to disconnect the electrical connection between the battery control unit and the cell when the driving switch is switched on, the driving switch being switched off in a default setting;
a movable stop arm, one end of the movable stop arm being outside the insertion opening and blocking the same, the movable stop arm being movable toward the driving switch to touch and switch on the driving switch;
a power wire, one end of the power wire including a plug connector adapted for insertion into the receptacle connector; and
a host computer electrically connected to the electronic apparatus and the main power source, the other end of the power wire being electrically connected to the host computer, the host computer managing electrical power distribution among the main power source, the electronic apparatus, and the power module.

7. The uninterruptible power supply of claim 6 , wherein the other end of the movable stop arm is fixed to the power module, so as to restrict the movable stop arm to be movable between the insertion opening and the driving switch.

8. The uninterruptible power supply of claim 6 , wherein when the driving switch is switched on, the driving switch drives the battery control unit to disconnect the electrical connection between the cell and the receptacle connector.

9. The uninterruptible power supply of claim 6 , wherein the movable stop arm is so resilient as to be restorable to its initial position outside the insertion opening to block the same.

10. The uninterruptible power supply of claim 6 , further comprising a signal line connected to the battery control unit and the host computer, the signal line being provided for the battery control unit to obtain a voltage state of the host computer, the battery control unit controlling each of the cells to perform charging or discharging based on the voltage state of the host computer.

11. The uninterruptible power supply of claim 6 , wherein the uninterruptible power supply comprises plural receptacle connectors and plural driving switches, each of the receptacle connectors is electrically connected to the cell via the battery control unit, and each of the driving switches is disposed corresponding to a respective one of the receptacle connectors and is electrically connected to the battery control unit.

12. The uninterruptible power supply of claim 6 , wherein a lug is protrudingly disposed at a side surface of the plug connector, and when the plug connector is inserted into the receptacle connector, the lug pushes against the movable stop arm so as to switch on the driving switch.

13. The uninterruptible power supply of claim 12 , wherein a through hole for insertion of a screw is formed on the lug, so as to screw the plug connector to the power module.

14. The uninterruptible power supply of claim 6 , wherein each of the cells is a lithium cell.

15. A charging-discharging method of a battery assembly, comprising steps as follows:
a. providing a power module, a receptacle connector, a driving switch, and a movable stop arm, the power module comprising a battery control unit and at least one cell electrically connected to the battery control unit, the receptacle connector being electrically connected to the cell via the battery control unit, the driving switch being electrically connected to the battery control unit, the driving switch being switched off in a default setting;
b. detecting an ON-OFF state of the driving switch by means of the battery control unit, and the method proceeding to a step c if it is detected that the driving switch is in the ON state.
c. disconnecting the electrical connection between the receptacle connector and the cell;
d. following from the step c, adjusting the voltage state of the cell by means of the battery control unit; and
e. following from the step d, switching the receptacle connector and the cell into the ON state by means of the battery control unit.

16. The charging-discharging method of the battery assembly of claim 15 , wherein in the step a, one end of the movable stop arm blocks the receptacle connector and is movable toward the driving switch to touch and switch on the driving switch, and the charging-discharging method of the battery assembly further comprises a step f: following from the step a, moving the movable stop arm away from the receptacle connector to touch and switch on the driving switch.

17. The charging-discharging method of the battery assembly of claim 16 , wherein in the step a, a host computer and a power wire are provided, one end of the power wire is electrically connected to the host computer, the other end of the power wire includes a plug connector for insertion into the receptacle connector, and the charging-discharging method of the battery assembly further comprises
