Abstract

Availability of a simulation model of a battery is one of the most important requisites in the system-level design of battery-powered systems. The vast majority of the models describe the discharge behavior of the battery; so far, the estimation of charging time has been in fact only marginally studied because the charging phase is regarded as a relatively controlled process compared to discharge. In this paper, we present a compact macro-model for the estimation of charging time under the most widely used charge protocol, i.e., Constant Current-Constant Voltage (CC-CV). This model is derived under the consideration of the context of the existing models including the well-known Peukert’s law and equivalent electric circuits. The estimation result with the proposed model based on the manufacturer’s data of commercial Li-ion batteries shows fair accuracy, especially when compared to estimates on parameters extracted from discharge characteristics.
