A modular battery system comprising at least two battery modules, wherein each battery module has a cooling element, through at least part of which a coolant flows, and a battery cell, wherein the battery cell is arranged on the cooling element in such a way that heat-conducting contact is established between the battery cell and the cooling element, and a coolant supply with a coolant carrier for distributing the coolant to the cooling elements or for carrying the coolant away from the cooling elements is provided, wherein the coolant carrier has coolant carrier modules that can be connected to one another and that at least partially form the coolant carrier, and wherein, to enable the flow length of the coolant in the coolant supply to be adapted, a deflection device is provided in the coolant carrier to reverse the direction of flow of the coolant in the coolant carrier, and the coolant carrier has two flow channels at least in one longitudinal portion, in which flow channels the coolant can be carried substantially in opposite directions.
A battery system comprising at least two battery modules arranged in series, wherein each battery module has a cooling element, through at least part of which a coolant in a cooling channel flows, and a battery cell, which is arranged in heat-conducting contact with the cooling element, and a coolant supply with a coolant distributor for distributing the coolant from a coolant supply device, in particular a coolant reservoir or a coolant pump, to the cooling elements, and a coolant collector for carrying the coolant away from the cooling elements to the coolant supply device, in particular the coolant reservoir or the coolant pump, is provided, wherein the coolant distributor is constructed from coolant distributor modules associated with the cooling elements, and the coolant collector is constructed from coolant collector modules associated with the cooling elements, and a deflection device is provided in the coolant distributor to reverse the direction of flow of the coolant in the coolant distributor, and furthermore the coolant distributor has two flow channels at least in one longitudinal portion, in which flow channels the coolant can be transported substantially in opposite directions, wherein the coolant distributor is arranged on a first side of the cooling elements and the coolant collector is arranged on a second side of the cooling elements.
A method for supplying coolant in a battery system comprising a plurality of battery modules arranged in series, wherein each battery module has a cooling element, which is embodied with a cooling channel, and a battery cell, which is arranged in heat-conducting contact with the cooling element, wherein a coolant flows through the cooling channel, and a coolant supply with a coolant distributor is provided, the coolant distributor being configured to distribute the coolant from a coolant supply device, in particular from a coolant reservoir or a coolant pump, to the cooling elements, and a coolant collector for carrying the coolant away from the cooling element to the coolant supply device, in particular to the coolant reservoir or the coolant pump, is further provided, wherein the coolant distributor is constructed at least partially from coolant distributor modules, and the coolant collector is constructed at least partially from coolant collector modules, and, to enable the flow length of the coolant through the coolant supply to be adapted, the coolant distributor has, at least in one longitudinal portion, a first and a second flow channel and a deflection device and a number of lateral openings in the second flow channel, and the coolant is passed through the first flow channel in a first step, is deflected substantially by 180° by the deflection device in a second step, and is passed through the second flow channel in a third step before the coolant is fed to the cooling elements via the lateral openings.
