Embodiment Construction

[0032] figure 1 A very simplified schematic block diagram of an example electric vehicle with an electric air conditioning system and an electric drive 1 , which is supplied with electrical energy via an electric energy store 10 , for example a lithium-ion battery, is shown. The air conditioner provides a cooling function and optionally a heating function for the electrical energy store 10 .

[0033] An exemplary air conditioning unit includes a coolant circuit. The electric coolant compressor 2 of the coolant circuit sucks in cold, gaseous coolant and compresses it. The electric coolant compressor 2 has an electric motor and the actual compressor driven by the electric motor. The electric coolant compressor 2 is supplied with electric energy by an electric storage device 10 . Furthermore, a liquefier 3 (also referred to as a condenser) is provided, in which the coolant gas is cooled and simultaneously liquefied by releasing thermal energy to the environment. In the evapor...

Abstract

The invention relates to a method for charging an electric vehicle and air-conditioning of the vehicle interior. Specifically, the method is provided for charging an electric vehicle with an electric energy accumulator and for stationary mode air conditioning the vehicle interior by way of an electric air conditioning system. According to the method, the electric energy accumulator is charged to a minimum state of charge. After the energy accumulator has reached the minimum state of charge, the interior is air conditioned in such a way that at an assumed departure time a preset air conditioning state of the interior is reached. The energy accumulator is charged to a target state of charge with any excess energy that is not required to reach the air conditioning state.

Description

technical field [0001] The invention relates to a method for charging an electric vehicle and for air-conditioning the vehicle interior. Background technique [0002] In addition to conventional electric vehicles, electric vehicles are also to be understood as electric vehicles with a range-extender (Range-Extender) and plug-in hybrid vehicles. [0003] When using an electric drive, the air conditioning, in particular cooling, of the vehicle interior can be carried out independently of the operation of the drive. Electric vehicles typically employ an electric air conditioning system comprising one or more electric consumers, such as an electric coolant compressor in the coolant circuit and / or an electric heater for heating the interior air. In contrast, in a conventional internal combustion engine powered vehicle the coolant compressor is typically driven mechanically via the drive train and a heat exchanger heated by the heat of the coolant is used as a heater. Parking he...
