The invention discloses a battery aging detection method and a device thereof for a mobile terminal. The battery aging detection method includes: reading the battery charge and discharge times and the battery remaining capacity when starting up the battery, and calculating the current available total capacity of the battery according to the battery charge and discharge times; In the charging state, the current battery capacity is calculated according to the charging quantity and the remaining capacity of the battery, and the battery aging calculation is performed every preset time to update the battery charge and discharge times and the current battery capacity; when the shutdown is detected, the battery charge is stored For the number of discharges, the current battery capacity is stored as the remaining battery capacity. The method and device of the present invention are based on the charging and discharging characteristics of lithium batteries, without adding any electronic components, use battery aging calculations to more accurately count the charging and discharging conditions of batteries, and measure more accurate battery capacity and The total available capacity of the current battery saves costs.
Description
technical field [0001] The present invention relates to the field of mobile devices, in particular to a battery aging detection method and device for a mobile terminal. Background technique [0002] With the continuous development of mobile intelligent terminal equipment, accurate estimation of battery capacity becomes more and more important. Battery capacity refers to the amount of electricity stored in the battery. It is a parameter that cannot be directly measured. Many factors such as temperature, discharge rate, and battery aging may affect the battery capacity. [0003] When the battery is used for a period of time, the battery capacity will gradually decrease, so that many users feel that the battery is used up very quickly. The reason why the battery is used too quickly is that after many charge and discharge cycles, there is a phenomenon of battery aging based on the chemical characteristics of the battery. The reduction of battery capacity after aging affects th...
