Embodiment Construction

[0019] A high-voltage battery for a motor vehicle, generally designated 10 , consists of a plurality of lithium cells 12 , not all of which are shown in the figure for the sake of clarity. To achieve the desired terminal voltage of hundreds of volts, the lithium cells 12 are connected in series.

[0020] The individual cells 12 form a plurality of cell packs 14 and are each held by a corresponding common carrier support 15 . The support 15 is composed of a base frame 17 and a top cover 16 . Webs 19 protruding from bottom 21 of base frame 17 delimit receptacles for individual cells 12 . The roof panel 16 has a plastic base body 18 with a serpentine coolant line 32 extending over the entire surface of the roof panel 16 . When the battery 10 is in operation, a cooling medium flows through the coolant line in order to dissipate the heat accumulated in the unit cells 12 . Advantageously, the coolant line 32 is injected into the roof panel 16 .

[0021] It is especially suitable...

Abstract

The invention relates to a battery (10) for a motor vehicle, comprising a battery housing (40) in which at least one cell group (14) having a plurality of electrochemical cells (12) is accommodated, wherein the cells (12) of a cell group (14) are held on a respective cell carrier (15), wherein a cover part (16) of the cell carrier (15) comprises a coolant conduit (32) for cooling the cells (12) of the cell group (14). The cell carrier (15) thus combines a holding function and a cooling function, and for this reason such a battery (10) has a particularly simple design and is particularly lightweight. Good heat dissipation is ensured by the large surface area of the cover part (16).

Description

technical field [0001] The invention relates to a battery for a motor vehicle. Background technique [0002] To supply the drive system of an electric or hybrid vehicle with energy, a high-voltage battery with a high power density is used. In order to achieve the desired high terminal voltage, in such batteries a plurality of electrochemical cells are connected in series, whereby the relatively low terminal voltages of the cells add up to give the desired overall terminal voltage of the battery. Due to the high charging and discharging powers of such batteries during operation, the temperature of the individual electrochemical cells increases considerably when the battery is being charged or discharged. Therefore, such batteries must be cooled in order to avoid overheating. [0003] DE 10 2005 047 034 A1 discloses a device for cooling a vehicle battery, in which the individual cells of the battery are accommodated in a housing and are flushed with air by means of a blower....
