As shown in Figure 1, the embodiment of the present invention provides a kind of battery pack assembling side that can be applied to power battery assembly
Method, the battery pack assemble method the following steps are included:
Step S10, the lower box of battery pack is placed on assembly line.
In the present embodiment, the assembly line can for example use the spliced two-layer cylinder assembly line being mentioned below,
Including several stations, the number of station can be adjusted flexibly according to the packaging technology process of battery pack, be set on each station
It is equipped with corresponding equipment and instrument, for completing one or more processing steps in battery pack assembling process.
Such as can use the starting point that the lower box of battery pack is transported to assembly line by fork truck, cantilever can be used for example
It hangs and is placed on the lower box of battery pack according to productive temp on the pallet of assembly line starting point, and the lower box of battery pack is held
The detection of row pipeline, cabinet cleaning are laid with resilient cushion, and printing is pasted during nameplate, bar code and installation check water-cooled plate etc.
One or more combination.
Specifically, dust or residue before vacuum lower box and buckle closure can be used for example guarantee cleaning.
It should be noted that further including the steps that online frontier inspection looks into water cooling plate tightness before installation detection water-cooled plate.
Step S20, battery pack assembly is installed in Yu Suoshu lower box.
In the present embodiment, the battery pack assembly for example may include battery modules, battery management system (Battery
Management System, BMS), high potential assembly, fire extinguishing component, water cooling tube, air plug plate and heating film.It needs to illustrate
, in other embodiments, the battery pack assembly can also select battery modules, battery management system according to actual needs
It unites (Battery Management System, BMS), high potential assembly, fire extinguishing component, water cooling tube, air plug plate, and heating
One or more combination in film, naturally it is also possible to as needed, increase new other battery pack assemblies or battery pack zero
Part.
