NOVELTY - The system (100) comprises a module fixture supporting battery cells, a dispensing system coupled to the module fixture for dispensing an adhesive into each bonding well and surrounding first portions of each battery cell, a curing structure for selectively exposing the adhesive to a curing modality in a multistep curing process, and a modality transparent fixture coupled to a second portion of the battery cells different from the first portion. The module fixture defines the bonding wells with each bonding well accepting the first portion of the battery cells with the module fixture.    USE - The system is useful for a battery module assembly construction used in electric vehicles.    ADVANTAGE - The system is capable of effectively and economically constructing the battery module assembly with less cure time, reduced adhesive and high robustness and productivity.    DETAILED DESCRIPTION - The system (100) comprises a module fixture supporting battery cells, a dispensing system coupled to the module fixture for dispensing an adhesive into each bonding well and surrounding first portions of each battery cell, a curing structure for selectively exposing the adhesive to a curing modality in a multistep curing process, and a modality transparent fixture coupled to a second portion of the battery cells different from the first portion. The module fixture: defines the bonding wells with each bonding well accepting the first portion of the battery cells with the module fixture including apertures communicated with the bonding wells having a nominal depth; includes a first battery fixture clamshell, a second battery fixture clamshell, and adhesive guiding structures directing the dispensing adhesive to the bonding surfaces in the bonding wells between a portion of the battery cells and the fixture; and is transparent to the curing modality with a seal zone defined by a mask opaque to the curing modality. The adhesive: is selectively curable upon application of the curing modality; includes a wettability characteristic during dispensing with the first portion of the adhesive having a different wettability than a second portion, and an indicator representing a state of cure of the adhesive; and fills the bonding wells up to the nominal depth without overfilling the bonding wells. The wettability parameters consist of a viscosity of 50-500 centipoises. A first curing step exposes the first portion of the adhesive emerging from the apertures and not exposes the second portion to the curing modality as the first portion of adhesive emerges from apertures during dispensation of adhesive into the bonding wells. A second curing step exposes the second portion of the adhesive after the first curing step. A surface tension with a substrate of the bonding wells produces a contact angle with the adhesive less than 5 degrees in air. The bonding wells accept the first portions of the battery cells. The bonding wells are formed from counter-bores in the clamshells with the portions of the batteries accepted within the counter-bores including an end of the battery cell. Each counter-bore populated with the end of one of the battery cells has a portion of a wall of the clamshell defining a contact port aperture communicated to the counterbore allowing electrical communication to the end of the battery cell from outside the clamshell. The wettability of the second portion is greater or less than the wettability of the first portion. The selectively curable adhesive is curable upon exposure to modalities consisting of UV, electron beam, peroxide, cationic, amine, hydroxyl groups and/or thermal. The curing modality includes application of selected modalities to the identified portions of the dispensed adhesive. The adhesive guiding structures include structures consisting of ramps, channels, counterbores and/or sloped walls. The modality-transparent fixture is coupled to the second portion of the battery cells during a wetting of the battery cells by a dispensed adhesive. The curing structure applies the curing modality to all exposed dispensed adhesive. A portion of an external surface of each of the battery cells includes curing modality redirecting component for redirecting the curing modality into a body of the module fixture that promotes an inter-element bonding. The seal zone includes regions surrounding the apertures. An INDEPENDENT CLAIM is included for a bonding method for a battery module assembly construction.
