Abstract
A communication device includes a battery, a communication module, a first charging circuit between the battery and the communication module, a fast charge signal, a second charging circuit between the battery and the communication module, and a control module configured to route power from the battery to the communication module via the second charging circuit in response to the fast charge signal being enabled and to route the power via the first charging circuit in response to the fast charge signal being disabled.
Claims20
A communication device:
- a battery;
- a communication module;
- a first charging circuit between the battery and the communication module, the first charging circuit comprising a capacitor system connected in series with a first resistor between the battery and the capacitor system;
- a fast charge signal;
- a second charging circuit between the battery and the communication module, the second charging circuit comprising the capacitor system connected in series with at least one second resistor between the battery and the capacitor;
- and
- a control module configured to route power from the battery to the communication module via the second charging circuit in response to the fast charge signal being enabled and to route the power via the first charging circuit in response to the fast charge signal being disabled.
One or more hardware-based non-transitory memory devices storing computer-readable instructions which, when executed by the one or more processors disposed in a computing device, cause the computing device to:
- determine a current operating temperature for a communication module.
- charge a capacitor through a first resistor, to supply power to the communication module, if the current operating temperature is above a threshold;
- activate a fast-charge circuit, if the current operating temperature is below a threshold;
- and
- charge a capacitor through a second resistor, to supply power to the communication module, if the operating temperature is below the threshold;
- wherein the one or more hardware-based non-transitory memory devices further include routing the power from a battery to the communication module through a capacitor system, and
- wherein the first resistor has a higher value than the second resistor.
A method for communication comprising:
- determining a current operating temperature for a communication module;
- charging a capacitor system through a first resistor, to supply power to the communication module, if the current operating temperature is above a threshold;
- activating a fast-charge circuit, if the current operating temperature is below a threshold;
- and
- charging the capacitor system through a second resistor, to supply power to the communication module, if the operating temperature is below the threshold.
