The invention relates to a method for estimating a limit value (TLV) for an interior temperature input of a passenger compartment (12) of a vehicle (10). The vehicle (10) comprises an energy storage source (30) and a temperature control arrangement (14) adapted to control the interior temperature of the passenger compartment (12) of the vehicle (10) on the basis of the interior temperature input. The temperature control arrangement (14) is adapted to be powered by the energy storage source (30) during at least one operating condition of the vehicle (10). The method comprises: -determining a temperature control time period (Δt) during which the temperature control arrangement (14) is intended to be powered by the energy storage source (30); -determining an ambient environment parameter (EP) indicative of the environment ambient of the vehicle (10) during the temperature control time period (Δt); -determining a state of charge (SOC) of the energy storage source (30) on or before a starting time of the temperature control time period (Δt) and-determining the limit value (TLV) as the interior temperature input that can be used throughout the temperature control time period (Δt) on the basis of at least the temperature control time period (Δt), the ambient environment parameter (EP) and the state of charge (SOC).
