Abstract

The present disclosure relates to techniques in the context of vehicles, and to a method for controlling energy levels of energy storage devices in a vehicle comprising a plurality of drive modules. According to a first aspect, the disclosure relates to a method for controlling energy levels of energy storage devices in a vehicle comprising a plurality of drive modules, wherein each drive module comprises an individual propulsion system operable to propel the vehicle and a chargeable energy storage device arranged to supply energy to the propulsion system. The method comprises determining energy levels of the chargeable energy storage devices of the plurality of drive modules, controlling operation of the individual drive modules, while operating the vehicle, based on the determined energy levels. The disclosure also relates to a corresponding control device, to a vehicle comprising the control device, to a computer program and a computerreadable medium.
