Abstract
Methods, systems, and apparatuses for charging a battery in a mobile device are described. In embodiments described herein a power supply voltage and/or a power supply current of a power supply coupled to charger of the mobile is reduced. The reduction in power supply voltage and/or current results in a reduction in heat dissipation and power dissipation by the charger.
Claims10
A system for charging a battery of a mobile device, comprising:
- a limited power supply, including:
- a limiter module;
- and
- a monitoring module;
- wherein the limiter module is configured to limit a power supply voltage of the limited power supply based at least on observations of a battery voltage taken by the monitoring module.
2 more elements
A method for charging a battery in a mobile device, comprising:
- monitoring a battery voltage at a first time instant;
- generating a limited power supply voltage, wherein the limited power supply voltage is generated based at least on the battery voltage observed at the first time instant, wherein the limited power supply voltage level is substantially equal to a minimum voltage level required by a charger to charge the battery at the first time instant;
- and
- powering the charger with the limited power supply voltage.
