THERMAL MANAGEMENT FOR CONCURRENT WORKLOAD EXECUTION AND FAST CHARGING
First Claim
1. A method of thermal management for a mobile device, comprising:
- determining a thermal headroom, which is an amount of power in a form of heat that heat dissipation hardware in the mobile device is estimated to dissipate when the mobile device operates at a target temperature;
determining a first power allocation to system loading caused by one or more applications running on the mobile device;
subtracting the first power allocation from the thermal headroom to obtain a second power allocation to a charger that charges a battery module of the mobile device while the one or more application are running; and
setting an input power limit of the charger based on the second power allocation.

Abstract
A mobile device performs thermal management during concurrent battery charging and workload execution based on a thermal headroom. The thermal headroom is an amount of power, in a form of heat, that heat dissipation hardware in the mobile device is estimated to dissipate when the mobile device operates at a target temperature. After the thermal headroom is determined, the mobile device determines a first power allocation to system loading, which is caused by one or more applications running on the mobile device. The first power allocation is subtracted from the thermal headroom to obtain a second power allocation to a charger, which charges a battery module of the mobile device while the one or more application are running. The mobile device then sets an input power limit of the charger based on the second power allocation.
