Abstract
Systems and methods for limiting battery discharge based on battery temperature are disclosed. In an example, a controller sets a current limit, using battery temperature, and provides corresponding current limits to a power management device and a system-on-chip (SOC). Upon battery discharge current exceeding the discharge current limit, the controller increases the discharge current limit, and provides updated current limits to the PM device and the SOC. Upon the battery temperature exceeding a battery pack maximum temperature, the controller issues a shutdown command to the PM device and the SOC.
