The invention discloses an under-vehicle connection gun, an on-vehicle connection socket and a liquid cooling device. The under-vehicle connecting gun is used for being connected with an on-vehicle connecting socket arranged on the vehicle in an inserted mode. The under-vehicle connecting gun comprises a plugging end, the plugging end comprises a liquid supply plug and a liquid return plug, and the liquid supply plug and the liquid return plug are connected with the liquid cooling unit through pipelines. The plugging end further comprises a first connection confirmation terminal, one end of the first connection confirmation terminal is used for being connected with a first connection confirmation socket of a vehicle connection socket, and the other end of the first connection confirmation terminal is used for being connected with a first connection confirmation circuit. When the first connection confirmation terminal is connected with the first connection confirmation socket, the first connection confirmation circuit and the connection confirmation circuit connected with the first connection confirmation socket form a first connection confirmation loop, and the first connection confirmation loop is used for confirming the connection state of the liquid supply plug and the liquid return plug with the on-vehicle connection socket. The liquid cooling unit can be used for improving the heat dissipation capacity of the battery management system on the vehicle power battery, and the battery overcharge heat dissipation requirement is met.

    公开了一种车下连接枪、车上连接插座及液冷装置。车下连接枪用于和设置在车辆上的车上连接插座插接连接。车下连接枪包括插接端,插接端包括供液插头和回液插头,供液插头和回液插头通过管路连接液冷机组。插接端还包括第一连接确认端子,第一连接确认端子的一端用于连接车上连接插座的第一连接确认插座,第一连接确认端子的另一端用于连接第一连接确认电路。在第一连接确认端子与第一连接确认插座连接时,第一连接确认电路与第一连接确认插座连接的连接确认电路组成第一连接确认回路,第一连接确认回路用于确认供液插头和回液插头与车上连接插座的连接状态。可以利用液冷机组提升电池管理系统对车辆动力电池的散热能力,满足电池超充散热需求。
