Abstract

The invention relates to a method for preheating a battery (4) of an electrically driven motor vehicle (2), in particular an electric vehicle or a hybrid vehicle, wherein a charging process and a discharging process of the battery (4) are controlled in such a way that a minimum temperature (Tmin) of the battery (4) is attained at a departure time (tA) of the motor vehicle (2). The invention further relates to a charging device (6) for said type of motor vehicle (2) and to a motor vehicle (2) comprising said type of charging device (6).

Description

technical field [0001] The invention relates to a method for preheating a battery of an electrically operated motor vehicle, in particular an electric vehicle or a hybrid vehicle. Furthermore, the invention relates to such a charging device for a motor vehicle as well as to a motor vehicle comprising such a charging device. Background technique [0002] Rechargeable accumulators are installed in electrically driven motor vehicles, such as in electric vehicles or in hybrid vehicles including an electric drive. The accumulator is connected to the power grid by means of a charging device and charged if necessary. It is conceivable here that the charging process of the accumulator starts directly after the connection to the grid. If the vehicle has not been used for a relatively long period of time, for example at night, the charging process can therefore have ended for a relatively long period of time at the time of departure. [0003] A method is disclosed in DE 10 2009 038...
