Method for monitoring a state of charge of a battery

Abstract

A method of controlling a state of charge (SOC) of a battery is provided. The method comprises defining a first SOC threshold of the battery, the first SOC threshold being greater than zero and defining a second SOC threshold of the battery, the second SOC threshold being less than a highest charge capacity of the battery. The first and second SOC thresholds define a battery protection charge range of the battery based on a predetermined battery protection charge range associated with the battery. The method also comprises setting a first configurable SOC threshold of the battery, the first configurable SOC threshold being at least the first SOC threshold; and setting a second configurable SOC threshold of the battery, the second configurable SOC threshold being no greater than the second SOC threshold and greater than the first configurable SOC threshold. A range between the first and second configurable SOC thresholds is defined by a configurable capacity associated with the battery. During charging and/or discharging of the battery, the SOC of the battery is controlled based on the first and second configurable SOC thresholds. The configurable capacity of the battery and the first and second configurable SOC thresholds are updatable upon receiving an update to the configurable capacity of the battery.
