Abstract

The invention provides a battery pack, a battery pack manufacturing device, and a battery pack manufacturing method. The battery pack includes: a battery pack lower shell, the battery pack lower shellcomprising an isolation plate and a lower shell frame, the lower shell frame surrounding the periphery of the isolation plate, at least one cross beam being arranged on the first side of the lower shell frame, the space formed by the lower shell frame and the first side of the isolation plate being divided into at least one first cavity and a second cavity by the cross beam, the first cavity being provided with a battery module, and the second cavity being provided with a battery management module; a liquid cooling plate assembly, arranged on the second side of the lower shell frame, the liquid cooling plate assembly being provided with a plurality of liquid cooling pipes, and the liquid cooling pipes being in surface contact with the area, corresponding to the first cavity, in the secondside of the isolation plate for heat exchange; and a bottom cover, sealed the liquid cooling plate assembly on second side of lower shell frame. According to the battery pack, water and electricity isolation between the battery module and the battery management module can be achieved, and the use safety of the battery pack is greatly improved.

Description

technical field [0001] The invention relates to the field of battery packs, in particular to a battery pack, a battery pack manufacturing device and a battery pack manufacturing method. Background technique [0002] IEA goal: to achieve global CO2 by 2050 2 Emissions will be reduced by 50% on the basis of 2005. Among them, the reduction of greenhouse gas emissions in the field of transportation to 30% requires the rapid expansion of the market share of new energy vehicles and the promotion of the development of new energy vehicle technology. As the drive system of new energy vehicles, the power battery system is the focus of urgent research in the development of new energy vehicles. [0003] The power battery system generally includes battery modules, battery management systems, structural parts, sensors, wiring harnesses, thermal management systems, accessories, etc. During the charging and discharging process of the battery pack, especially the high-rate charging and di...
