Abstract
A method and a system are provided for determining a maximum charge current or a maximum discharge current of an energy storage cell of an energy storage device. The method includes providing a predetermined upper voltage limit or lower voltage limit, and providing a time horizon as a time difference from a present time to a future time. The method also include, with a repetition time period different from the time horizon, repeating measuring a present voltage level of the energy storage cell, calculating a voltage difference between the present voltage level and the upper voltage limit or the lower voltage limit, and determining the maximum charge current or maximum discharge current corresponding to the voltage difference and a model, such that the estimated voltage is within the voltage limits.
