Abstract

A battery having integrated safety and power management controller is described. In an embodiment a battery, comprises: at least one battery cell; and a printed circuit board, PCB, comprising a safety controller of the at least one battery cell and a power management controller of a device using a power of the battery; wherein the power management controller comprises power outputs directly outputting a power of the battery to at least one module of the device; and wherein the safety controller and the power management controller are integrated into the same PCB of the battery.

Claims

1. A battery, comprising:

at least one battery cell; and

a printed circuit board (PCB) comprising a safety controller of the at least one battery cell and a power management controller of a device using a power of the battery;

wherein the power management controller comprises power outputs directly outputting a power of the battery to at least one module of the device; and

wherein the safety controller and the power management controller are integrated into the same PCB of the battery; and

wherein the at least one module comprises a display module, wherein the display module is configured to be stacked on top of the battery and comprises a flex having a connection interface of the display module, wherein the flex is configured on top of the PCB and the connection interface is configured to contact the PCB of the battery.

2. The battery of claim 1, wherein the power management controller comprises an integrated circuit that is integrated into the PCB.

3. The battery of claim 1, wherein the safety controller comprises an integrated circuit that is integrated into the PCB.

4. The battery of claim 1, wherein the safety controller and the power management controller comprises a single united circuit integrated into the PCB.

5. The battery of claim 1, wherein the power outputs are configured directly on the power management controller, and a power output of the at least one battery cell is configured only to the PCB without a direct connection to the at least one module.

6. The battery of claim 1, further including a battery housing encapsulating the at least one battery cell and the PCB.

7. The battery of claim 1, wherein the PCB is positioned at an end of the battery.

8. The battery of claim 1, wherein the flex is configured to be bent under the display module.

9. The battery of claim 1, wherein the power management controller is configured to control a power usage of the battery for the device.

10. The battery of claim 1, wherein the safety controller is configured to protect the at least one battery cell against excess voltage, current or temperature.

11. A device, comprising:

a battery, comprising;

at least one battery cell,

a printed circuit board (PCB) comprising a safety controller of the at least one battery cell and a power management controller of the device using a power of the battery,

wherein the power management controller comprises power outputs directly outputting a power of the battery to at least one module of the device,

wherein the safety controller and the power management controller are integrated into the PCB of the battery; and

wherein the at least one module comprises a display module, wherein the display module is configured to be stacked on top of the battery and comprises a flex having a connection interface of the display module, wherein the flex is configured on top of the PCB and the connection interface is configured to contact the PCB of the battery.

12. The device of claim 11, wherein a housing of the device encapsulates the battery and at least edges of the display module.

13. The device of claim 11, wherein the power management controller comprises an integrated circuit that is integrated into the PCB, and wherein the safety controller comprises an integrated circuit that is integrated into the PCB.
