Abstract

(EN) Disclosed are a battery device (100), an energy storage device and an electric device. The battery device (100) comprises a case (10), a plurality of battery cells (20), and a heat exchange assembly (30). The case (10) is provided with an interface member (13) in communication with the outside. The plurality of battery cells (20) are arranged inside the case (10). The heat exchange assembly (30) is arranged inside the case (10), the heat exchange assembly (30) being configured to exchange heat with the battery cells (20). The heat exchange assembly (30) comprises a heat exchange main body (31), a fluid collector (32), a connecting member (33) and a connector (34). The heat exchange main body (31) has a medium flow channel inside, and the heat exchange main body (31) is arranged between adjacent battery cells (20). The fluid collector (32) is connected to at least one end of the heat exchange main body (31), and the fluid collector (32) is in communication with the medium flow channel. The connecting member (33) connects a plurality of fluid collectors (32). At least one connector (34) is provided, and the connector (34) connects the fluid collector (32) and the interface member (13).

(FR) L'invention concerne un dispositif de batterie (100), un dispositif de stockage d'énergie et un dispositif électrique. Le dispositif de batterie (100) comprend un boîtier (10), une pluralité d'éléments de batterie (20) et un ensemble d'échange de chaleur (30). Le boîtier (10) est pourvu d'un élément d'interface (13) en communication avec l'extérieur. La pluralité d'éléments de batterie (20) sont disposés à l'intérieur du boîtier (10). L'ensemble d'échange de chaleur (30) est disposé à l'intérieur du boîtier (10), l'ensemble d'échange de chaleur (30) étant conçu pour échanger de la chaleur avec les éléments de batterie (20). L'ensemble d'échange de chaleur (30) comprend un corps principal d'échange de chaleur (31), un collecteur de fluide (32), un élément de liaison (33) et un connecteur (34). Le corps principal d'échange de chaleur (31) contient un canal d'écoulement de milieu, et le corps principal d'échange de chaleur (31) est disposé entre des éléments de batterie adjacents (20). Le collecteur de fluide (32) est relié à au moins une extrémité du corps principal d'échange de chaleur (31), et est en communication avec le canal d'écoulement de milieu. L'élément de liaison (33) relie une pluralité de collecteurs de fluide (32). Au moins un connecteur (34) est disposé de manière à relier le collecteur de fluide (32) et l'élément d'interface (13).

(ZH) 一种电池装置(100)、储能装置和用电装置被公开。电池装置(100)包括箱体(10)、多个电池单体(20)和换热组件(30)。箱体(10)设有与外部连通的接口件(13)。多个电池单体(20)排布在箱体(10)内。换热组件(30)设置在箱体(10)内，换热组件(30)配置为与电池单体(20)进行热交换。换热组件(30)包括换热主体(31)、集流体(32)、连接件(33)和接头(34)。换热主体(31)内部具有介质流道，换热主体(31)设置于相邻电池单体(20)之间。集流体(32)连接换热主体(31)的至少一端，集流体(32)连通介质流道。连接件(33)连接多个集流体(32)。接头(34)配置为至少一个，接头(34)连接集流体(32)和接口件(13)。
