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.
Claims16
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.
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.
