Title
(EN) IMMERSION COOLING OF BATTERY DEVICE
(FR) REFROIDISSEMENT PAR IMMERSION DE DISPOSITIF DE BATTERIE
Abstract
(EN)
A battery device (100) is disclosed, comprising a plurality of cells (110), an enclosure (120) configured to accommodate the cells when they are at least partly immersed in a thermal management liquid, and at least one flow unit (130) arranged within the enclosure to control a flow of the thermal management liquid through the enclosure. The at least one flow unit comprises a first electron (131) and a second electrode (132) that are arranged offset from each other and being connectable to a voltage source so as to affect the flow between the electrodes.
(FR)
L’invention concerne un dispositif de batterie (100), comprenant une pluralité de piles (110), une enceinte (120) servant à loger les piles lorsqu’elles sont au moins partiellement immergées dans un liquide de gestion thermique, et au moins une unité de circulation (130) agencée dans l’enceinte pour contrôler une circulation du liquide de gestion thermique à travers l’enceinte. L’unité ou les unités de circulation comprennent une première électrode (131) et une deuxième électrode (132) qui sont agencées de manière décalée l’une par rapport à l’autre et qui peuvent être connectées à une source de tension afin d’influencer la circulation entre les électrodes.
