Abstract: In a method of scheduling jobs in a storage device, a first job is performed. While the first job is being performed, a first timestamp for the first job is pre-updated based on a pre-defined operation time table that represents a relationship between operations of the storage device and operation times. While the first job is being performed, scheduling requests are received that are associated with a second job to be performed after the first job. While the first job is being performed, a scheduling operation for selecting the second job is pre-performed based on the scheduling requests and the timestamps.

Abstract: Methods and electronic devices for estimating state of charge (SOC) of a battery pack. Various embodiments provide a model comprising an (electrical) equivalent circuit model, an electrochemical (thermal) model, and a (convective) thermal model. The model estimates parameters pertaining to each cell of the battery pack individually, and determines the variations in the values of the parameters among each of the cells of the battery pack. The parameters include capacity, temperature current, voltage, and SOC. The parameters are computed based on at current drawn by the battery pack, electrochemical parameters, thermal parameters, and cell internal and connection resistances of the individual cells. Various embodiments compute battery pack uptime, chargeable capacity of the battery pack and SOC of the battery pack, based on the values of the parameters.
