Battery arrangement and method for cooling a battery

摘要

A battery arrangement has a battery (10, 100, 200) having battery cells (11, 111, 211) with in each case two terminals (12, 112, 212) and a terminal plate (15, 115, 215), on which a terminal (12, 112, 212) of each battery cell (11, 111, 211) is arranged to connect the battery cells (11, 111, 211). A perforated plate (16, 216) is arranged above the terminal plate (15, 115, 215). A cooling medium is sprayed through the holes (17, 217) of the perforated plate (16, 216).

主权项

1. A battery arrangement comprising:
a battery having a plurality of battery cells arranged with spaces therebetween, each of the plurality of battery cells having an upper surface with a terminal arranged thereon; a terminal plate, arranged above the battery cells and having a plurality of upwardly facing concavities defining splash pots, each of the splash pots being connected respectively to the terminals of the battery cells, a plurality of terminal plate through holes formed in the terminal plate at locations spaced from the splash pots, the terminal plate through holes being aligned respectively with the spaces between the battery cells; and a perforated plate arranged above the terminal plate, the perforated plate having a plurality of perforated plate through holes aligned respectively with the splash pots, wherein a cooling medium sprayed into each of the plurality of perforated plate through holes is temporarily accommodated in the splash pots, and flows from the splash pots into the plurality of terminal plate through holes and down into the spaces between the battery cells.
