The invention relates to a method for controlling electrical connection of a plurality of battery packs (2) of an electric energy storage system (1) of a vehicle (100) to a load (4) during operation of the vehicle, the plurality of battery packs being configured to be selectively connected in parallel to the load, the method comprising the steps of:- obtaining operational data relating to present operating conditions of the electric energy storage system, wherein the operational data include at least a voltage of each one of the plurality of battery packs;- based on at least an operational mode of the electric energy storage system and on the voltage of each one of the battery packs, and by allowing simultaneous connection of at least two battery packs to the load, proposing a connection sequence for electrically connecting at least a subset of the plurality of battery packs to the load;- electrically connecting at least the subset of battery packs to the load in accordance with the proposed connection sequence.The method further comprises the step of:prior to connecting at least the subset of battery packs to the load, and based on at least an internal resistance of each one of the battery packs within at least the subset of battery packs, determining whether the proposed connection sequence fulfils a predetermined connection condition, wherein the step of connecting at least the subset of battery packs to the load is only performed if the connection condition is considered to be fulfilled.
