Semi-submerged module cooling

A vehicle, comprising:

• a battery module, comprising:
• a plurality of battery cells, each of the plurality of battery cells having an elongated housing and having a pole at one end of the elongated housing;
• a module housing arranged to accommodate the plurality of battery cells;
• and
• a cell holder arranged to hold individual battery cells of the plurality of battery cells and at least forming part of a division of an interior of the module housing into a first fluid chamber and a second fluid chamber;
• wherein the cell holder forms around each battery cell a first tight fit around the elongated housing at a first position recessed from the one end of the elongated housing and a second tight fit around the elongated housing at a second position recessed from an opposing end of the elongated housing to form a space between the first tight fit and the second tight fit;
• wherein the battery module further comprises:
• a fluid inlet port for allowing a coolant flow into the first fluid chamber;
• and
• a fluid outlet port for allowing a coolant flow from the second fluid chamber;
• wherein the first fluid chamber and the second fluid chamber are connected in a way that a coolant can pass from the first fluid chamber to the second fluid chamber.
