Abstract
Provided are a battery module, a method of manufacturing the same, and a resin composition applied to the method of manufacturing the same. A battery module manufactured with a simple process and low cost but having excellent output for the size thereof, a method of manufacturing the same, and a resin composition applied to the method of manufacturing the same are provided in the present invention.
Claims26
A method of manufacturing a battery module, comprising:
- injecting a resin composition into a module case of a battery module, the module case including a lower plate and a sidewall forming an inside space, and the resin composition being a room temperature curing type resin composition;
- accommodating a plurality of battery cells in the inside space of the module case such that a first end portion of each of the battery cells faces the lower plate, each of the plurality of battery cells having a second end portion opposite to the first end portion;
- and
- after the step of accommodating the plurality of battery cells in the inside space, curing the resin composition in the inside space of the module case so as to form a resin layer therein, the curing being performed by maintaining the injected resin composition at room temperature,
- wherein the resin layer partially fills the inside space of the module case, such that the resin layer contacts the lower plate of the module case and each of the first end portions of the plurality of battery cells, but the resin layer does not contact each of the second end portions of the plurality of battery cells
- wherein, of the lower plate and the sidewall, the resin layer contacts only the lower plate or the resin layer contacts the lower plate and the sidewall while defining a contact area of 70% or more with respect to only the lower plate.

A method of manufacturing a battery pack, comprising:
- positioning a resin composition within a case including a lower plate and a sidewall forming an inside space, and the resin composition being a room temperature curing type resin composition;
- after the step of positioning the resin composition within the case, accommodating a plurality of battery cells in the inside space of the case such that a first end portion of each of the battery cells faces the lower plate, each of the plurality of battery cells haying a second end portion opposite to the first end portion;
- and
- after the step of accommodating the plurality of battery cells in the inside space, curing the resin composition in the inside space of the case so as to form a resin layer therein, the curing being performed by maintaining the resin composition at room temperature,
- wherein the resin layer partially fills the inside space of the case, such that the resin layer contacts the lower plate of the case and each of the first end portions of the plurality of battery cells, but the resin layer does not contact each of the second end portions of the plurality of battery cells.
