Abstract: The present disclosure relates to a monitoring system for a vehicle, a vehicle comprising such a monitoring system, a method for monitoring such a vehicle and a computer program element for monitoring such a vehicle. The monitoring system comprises a display unit, an adjustment tool and a control unit. The control unit is configured to generate an energy flow map showing an energy flow from an energy storage system to at least one sub-system of the vehicle. The display unit is configured to display the energy flow map, to graphically emphasize the at least one sub-system and to display a current energy consumption of the sub-system. The control unit is further configured to adjust the energy consumption of the sub-system based on a user's input to the adjustment tool.
