(9) the lamination cooling back cell panel chamfered edge good to lamination.
(10) cell panel is framed up after aluminium section bar is poured into silica gel.Aluminium section bar assembled battery plate with band silica gel can prevent that steam from entering cell panel, and play good supporting role.
(11) terminal box is installed in the backboard face of assembly, and lead-out wire is pasted on the binding post of terminal box.
(12) to terminal box perfusion casting glue.
(13) keep flat to leave standstill and carry out electric performance test after doing removing surface after eight hours.
(14) with the special purpose packet packaging and warehousing of casing.
As mentioned above, although represented and explained the utility model that with reference to specific preferred embodiment it shall not be construed as the restriction to the utility model self.Under the spirit and scope prerequisite of the present utility model that does not break away from the claims definition, can make various variations in the form and details to it.
