Specific embodiment

Below by way of attached drawing combination specific embodiment, the present invention is described in further details.

As shown in Figure 1 to Figure 3, battery module waterproof technology of the present invention is main including the following steps: (1) in battery mould Block electric connection line periphery puts on heat-shrink tube 3；(2) isolation board 1 in each face paste of battery module, and make electric connection line at it In be pierced by between two pieces of isolation boards 1；(3) acetic acid cloth base adhesive tape is being sticked in electric connection line position: on acetic acid cloth base adhesive tape 2 Open up opening, and acetic acid cloth base adhesive tape 2 sticked on the isolation board 1 in electric connection line two sides, later will be through step (1) at Electric connection line after reason passes through the opening of acetic acid cloth base adhesive tape 2, and by 3 phase of heat-shrink tube of acetic acid cloth base adhesive tape 2 and electric connection line Bonding；(4) will through step (3), treated that battery module periphery puts on heat shrinkage film 4, heat shrinkage film 4 is in the side of electric connection line It is formed with heat shrinkage film opening 41；It (5) will treated, and battery module heats through step (4)；(6) outside electric connection line Dispensing at junction and heat shrinkage film opening 41 between the heat shrinkage film 3 and acetic acid cloth base adhesive tape 2 in week；(7) adhesive tape 5 is sticked in At heat shrinkage film opening 41.

Preferably, further comprising the steps of between the step (1) and step (2), heat-shrink tube 3 and electric connection line 2 it Between filling gel.Isolation board is preferably epoxy plate in the step (2).PE film or PVC can be used in step (4) heat shrinkage film 4 Film, according to PE film in the step (5), then the temperature heated is 160 ~ 175 DEG C, preferably 164 ~ 170 DEG C, is added The hot time is 10 ~ 30 seconds, preferably 15 ~ 25 seconds；According to PVC film in the step (5), then the temperature heated is 130 ~ 145 DEG C, preferably 135 ~ 140 DEG C, heating time are 10 ~ 20 seconds, preferably 13 ~ 18 seconds.Using heat in the step (6) Melten gel dispensing, since hot melt adhesive and acetic acid cloth base adhesive tape are same sex compatible material, so that it is not easily to fall off after hot melt adhesive curing, if adopting With other materials, easily fallen off after heating adhesive curing.Adhesive tape 5 used in the step (7) is also acetic acid cloth base adhesive tape.

As shown in figure 4, by being soaked in water using the battery module of waterproof technology of the present invention, specific experiment scheme: 120min will be shelved in the water tank of product merging depth of water 50cm.Concrete outcome is dismantled as shown in figure 5, as shown in left hand view in Fig. 5 Heat shrinkage film 4, battery modules periphery water stain-free.As shown in right part of flg in Fig. 5, after heat shrinkage film 4 and isolation board 1 are dismantled, battery mould The internal water stain-free of group.

By above description as can be seen that battery module waterproof technology of the present invention, can prevent battery module Water conservation prevents battery module from meeting water and short circuit occurs, improves the safety in utilization and job stability of product.

Certainly, above is representative instance of the invention, and in addition to this, the present invention can also have other a variety of specific implementations Mode, all technical solutions formed using equivalent substitution or equivalent transformation, is all fallen within the scope of protection of present invention.
