Abstract

A battery provided with at least one battery cell electrically coupled to a battery management circuitry, a power regulation and supply circuitry, a USB-C port controller, an E-marker integrated circuit and a USB interface. The E-marker integrated circuit provided in-line along a CC conductor between the USB-C port controller and the USB interface. The USB-C port controller is configured to enable the E-marker integrated circuit upon reception of a vendor defined message via the USB interface which enables a high power delivery mode between the battery and a device without the presence of a separate interconnecting E-marker cable there between.

Claims (24)

1. A battery, comprising:

at least one battery cell electrically coupled to a battery management circuitry, a power regulation and supply circuitry, a USB-C port controller, an E-marker integrated circuit and a USB interface;

the E-marker integrated circuit provided in-line along a CC conductor between the USB-C port controller and the USB interface;

the at least one battery cell, the battery management circuitry, the power regulation and supply circuitry, the USB-C port controller, the E-marker integrated circuit and the USB interface provided within a body of the battery;

wherein the USB-C port controller is configured to enable the E-marker integrated circuit upon reception of a vendor defined message via the USB interface.

2. The battery of claim 1 , wherein the USB interface includes conductor contacts and a USB-C socket.

3. The battery of claim 2 , wherein the vendor defined message indicates that a device coupled to the conductor contacts requests a high-power mode.

4. The battery of claim 2 , wherein the body has a top face, a cylindrical terminal extending from a center of the top face, a top of the cylindrical terminal provided with the conductor contacts and the USB-C socket.

5. The battery of claim 2 , wherein the conductor contacts include a Vbus contact, and a CC contact.

6. The battery of claim 5 , wherein the Vbus contact and the CC contact are electrically coupled to corresponding conductors of the USB-C socket.

7. The battery of claim 5 , wherein the vendor defined message is received via the CC contact.

8. The battery of claim 1 , wherein the USB-C port controller enablement of the E- marker integrated circuit is via a general-purpose input/output port of the USB-C port controller that is electrically coupled to an enablement pin of the E-marker integrated circuit.

9. The battery of claim 1 , wherein the battery manager has an accelerometer for detecting inertial inputs as a means for switching between power modes of the battery.

10. A method for validating a high power mode for a battery, comprising the steps of:

providing at least one battery cell electrically coupled to a battery management circuitry, a power regulation and supply circuitry, a USB-C port controller, an E- marker integrated circuit and a USB interface;

the E-marker integrated circuit provided in-line along a CC conductor between the USB-C port controller and the USB interface;

the at least one battery cell, the battery management circuitry, the power regulation and supply circuitry, the USB-C port controller, the E-marker integrated circuit and the USB interface provided within a body of the battery; and

configuring the USB-C port controller to enable the E-marker integrated circuit upon reception of a vendor defined message via the USB interface.

11. The method of claim 10 , wherein the USB interface includes conductor contacts and a USB-C socket.

12. The method of claim 11 , wherein the conductor contacts include a Vbus contact, and a CC contact.

13. The method of claim 11 , wherein the vendor defined message is received via the CC contact.

14. The method of claim 10 , wherein the E-marker integrated circuit is enabled only if the battery has a capacity capable of providing the high power mode.

15. The method of claim 14 , wherein the high power mode is between the battery and a device direct connected to the battery via the USB interface.

16. The method of claim 15 , wherein the vendor defined message is recognized by the battery as a pre-arranged code signifying high power mode capability of the device.
