Abstract: The invention relates to an energy storage system for a vehicle, in particular a starter battery for a vehicle, having a plurality of energy storage cells for providing and/or storing electric energy and a housing which has a plurality of wall elements that delimit the interior of the housing. The housing is designed to receive the plurality of energy storage cells in the interior of the housing. A plurality of separating walls are arranged in the interior of the housing in order to divide the interior of the housing into a plurality of chambers, wherein each chamber is designed to receiving an energy storage cell. A fluidic connection is formed between the individual chambers, and a ventilation valve is arranged on one of the wall elements, preferably a cover element, of the housing in a respective region paired with the corresponding chamber. At least one of the ventilation valves is an active ventilation valve, and the remaining ventilation valves are blind closures.
