Abstract
A method for determining a battery state of charge (SOC) includes: determining a basic SOC of a battery of a terminal apparatus at a current time; determining rated and maximum power consumption parameters of the terminal apparatus in a time period between the current time and a reference time previous thereto; determining a reference SOC at the current time based on the rated power consumption parameter and an actual SOC at the reference time; determining a minimum SOC at the current time based on the maximum power consumption parameter and the actual SOC at the reference time; and judging whether the basic SOC is between the minimum SOC and the actual SOC at the reference time or not, and if yes, determining the basic SOC as an actual SOC at the current time, and if not, determining the actual SOC at the current time based on the reference and basic SOC.
