Embodiment Construction

[0040] exist figure 1 An electric vehicle 1 with a traction battery 4 is shown in FIG. In addition, in figure 1 A charging station 2 is shown in , which in particular enables rapid charging of the traction battery 4 of the vehicle 1 . In this case, charging station 2 has connecting lines 3 for electrically conductively connecting charging station 2 to traction battery 4 . Furthermore, the charging station 2 includes a cooling body 5 sunk into the ground 7 for cooling the traction battery arranged in the vehicle to be charged during the charging process at the charging station 2 . Here, the cooling body 5 is cooled by the cooling medium (in figure 1 not explicitly shown) flow through. In this case, the cooling body 5 communicates with the cooling device provided on the charging station 2 (in the figure 1 not explicitly shown in ), wherein the cooling device regulates the temperature of the cooling medium to a predetermined theoretical value.

Abstract

The present invention relates to a method for the temperature control of a traction battery (4) arranged in a vehicle (1) during a charging process at a charging station (2), wherein the traction battery (4) has at least one contacting surface for the thermal contacting of the traction battery (4). At least one heat sink (5) provided by the charging station (2) is thermally contacted with the at least one contacting surface of the traction battery (4), in such a way that an exchange of thermal energy between the at least one heat sink (5) and the traction battery (4) by means of the at least one contacting surface (10) thermally contacted with the at least one heat sink (5) is enabled and the traction battery (4) is temperature-controlled by means of the at least one heat sink (5) at least during the charging process. The present invention further relates to a charging station (2) for recharging a traction battery (4) arranged in a vehicle (1), wherein the traction battery (4) has at least one contacting surface for the thermal contacting of the traction battery (4), wherein the charging station (2) has means for performing a method according to the invention.

Description

technical field [0001] The invention relates to a method for tempering a traction battery arranged in a vehicle during a charging process at a charging station, wherein the traction battery has at least one contact surface for thermal contact of the traction battery. [0002] Furthermore, the invention relates to a charging station for carrying out such a method. Background technique [0003] In electrically driven vehicles, a rechargeable battery system known as a traction battery is used as the energy source. Such traction batteries can be recharged, in particular in plug-in hybrid vehicles or in electric vehicles, at charging stations provided for this purpose, wherein the connecting cable of the charging station is connected to the charging socket of the vehicle. Here, the problem is known from printed document DE 10 2010 007 975 A1 that high power losses occur during rapid charging, which leads to a high thermal load on the traction battery, specifically the battery ce...
