  "textContent": "The invention relates to a method (200) of computing a state of charge of an energy storage system, ESS, with multiple parallel battery packs, the method comprising: for each battery pack, predicting (210) a time-evolved terminal voltage and current based on a respective measured terminal voltage; based on the predicted time-evolved terminal voltages and currents, computing (212) a chargeable and/or dischargeable capacity of the ESS; and computing (214) the state of charge of the ESS based on the chargeable and/or dischargeable capacity of the ESS. The method may seek to provide an accurate computation of SoC for an ESS with multiple parallel battery packs such that the full capability of the ESS is utilized.",
