1. A method of cooling an array of battery cells within a chamber in a housing, the battery cells being electrically connected via a busbar having at least one terminal tab for connection to an electrical terminal in the housing, the method comprising the steps of:
supplying coolant through an opening in the housing into the chamber; and
diverting at least a part of the coolant flow from an inlet flow path due to impingement of the flow upon a body portion of the at least one terminal tab, the body portion being angled relative to an inlet flow axis of the coolant flow.
 
10. A battery comprising:
a housing defining a chamber in which an array of battery cells are provided, the housing having an electrical terminal;
an opening through the housing into the chamber through which, in use, coolant is supplied; and
a busbar electrically connecting the array of battery cells and having a terminal tab for connection to the electrical terminal, the terminal tab having a body portion angled relative to an inlet flow axis of the coolant,
wherein the terminal tab is positioned such that, in use, at least a part of the coolant flow impinges upon part of the terminal tab.
