Abstract
Methods and apparatus, including computer program products, are provided for device charging. In some example embodiments, there may be provided a method, which may include receiving, at a device, a request message to enter into a battery power supply mode; determining, by the device, whether to supply to a bus one of a battery source or a power charger source; and coupling, by the device based on the determining, one of the battery source or the power charger source to the bus to supply power to another device. Related systems, apparatus, and articles of manufacture may also be provided.
Claims20
A method comprising:
- receiving, at a device, a request message to enter into a battery power supply mode;
- determining, by the device, whether to supply to a bus one of a battery source or a power charger source;
- and
- coupling, by the device, based on the determining, one of the battery source or the power charger source to the bus to supply power to another device.
An apparatus comprising:
- at least one processor;
- and
- at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following:
- receive a request message to enter into a battery power supply mode;
- determine whether to supply to a bus one of a battery source to achieve a determination or a power charger source;
- and
- couple, based on the determination, one of the battery source or the power charger source to the bus to supply power to another device.
A non-transitory computer-readable storage medium including program code which, when executed by at least one processor, causes said at least one processor to perform operations comprising:
- receiving a request message to enter into a battery power supply mode;
- determining whether to supply to a bus one of a battery source or a power charger source;
- and
- coupling, based on the determining, one of the battery source or the power charger source to the bus to supply power to another device.
An apparatus comprising:
- at least one processor;
- and
- at least one memory including computer program code, the at least one memory and the computer program code configured with the at least one processor to cause the apparatus to perform at least the following:
- send a request message to a device to supply power to a voltage bus;
- determine a power supply type of the device;
- and
- couple, based on the determined the power supply type, one of a battery or a charging circuitry to the voltage bus to receive power from the device.
A method comprising:
- sending, by a host device, a request message to another device to supply power to a voltage bus;
- determining, by the host device, a power supply type of the another device;
- and
- coupling, by the host device, based on the determined power supply type, one of a battery or a charging circuitry to the voltage bus to receive power from the another device.
A non-transitory computer-readable storage medium including program code which, when executed by at least one processor, causes said at least processor to perform operations comprising:
- sending a request message to a device to supply power to a voltage bus;
- determining a power supply type of the device;
- and
- coupling, based on the determined power supply type, one of a battery or a charging circuitry to the voltage bus to receive power from the device.
