  "claims": [
    "1. A jig for assembly of a battery module, the jig comprising: a housing having a first accommodation portion configured to accommodate a battery cell and a second accommodation portion disposed so as to be spaced apart from the first accommodation portion, the second accommodation portion being configured to accommodate a circuit board in a state of being spaced apart from the battery cell, wherein the battery cell is accommodated in the first accommodation portion, and the circuit board is accommodated in the second accommodation portion, whereby an orientation of the circuit board with respect to the battery cell is maintained. 2. The jig according to claim 1, wherein the housing includes: an accommodation space partitioned by a partition wall as the first accommodation portion; and an opening formed through the partition wall as the second accommodation portion, the opening being provided with a step portion, on which the circuit board is settled. 3. The jig according to claim 1, further comprising a first protective cover configured to cover the battery cell accommodated in the first accommodation portion. 4. The jig according to claim 3, further comprising: a support unit, at which the housing is supported, wherein the first protective cover is turnably connected to the support unit. 5. The jig according to claim 4, wherein: the first protective cover is provided with a first contact portion configured to contact the housing, and the housing is moved in a state of being in contact with the first contact portion, whereby the first protective cover is turned to cover the battery cell accommodated in the first accommodation portion. 6. The jig according to claim 5, wherein a first spring is provided between the first protective cover and the support unit. 7. The jig according to claim 1, further comprising a second protective cover configured to cover the circuit board accommodated in the second accommodation portion, wherein the second protective cover includes a through-hole, that exposes a soldering portion of the circuit board to an outside, and wherein a connection member extending from the battery cell is attached to the soldering portion. 8. The jig according to claim 7, wherein: the second protective cover comprises an element exposure hole, through which an element provided on the circuit board is exposed, and the element exposure hole is formed so as to be spaced apart from the through-hole. 9. The jig according to claim 7, further comprising: a support unit, at which the housing is supported, wherein the second protective cover is turnably connected to the support unit. 10. The jig according to claim 9, wherein: the second protective cover is provided with a second contact portion configured to contact the housing, and the housing is moved in a state of being in contact with the second contact portion, whereby the second protective cover is turned to cover the circuit board accommodated in the second accommodation portion. 11. The jig according to claim 10, wherein a second spring is provided between the second protective cover and the support unit. 12. A battery module assembled using the jig according to claim 1. 13. A battery pack comprising a battery module assembled using the jig according to claim 1."

  "description_excerpt": "The present invention relates to a jig for assembly of a battery module, configured to support a battery cell and a circuit board during the process of electrically connecting the battery cell and the circuit board to each other in order to assemble a battery module.\n\nIn recent years, with an increase in the demand for portable electronic devices, such as laptop computers, smartphones, and tablet computers, research has been actively conducted on high-performance secondary batteries that are capable of being repeatedly charged and discharged. In addition, secondary batteries have come to be widely used in middle- or large-sized devices, such as vehicles, robots, and satellites, as well as small-sized devices, such as portable electronic devices. In particular, as fossil fuels are being depleted and increasing attention is being paid to environmental pollution, research on hybrid vehicles and electric vehicles is being actively conducted. The most essential part of a hybrid vehicle or an electric vehicle is a battery pack configured to supply electric power to a motor. The battery pack includes a battery module, which includes a plurality of battery cells. The plurality of battery cells are connected to each other in series and/or in parallel, whereby the capacity and output of the battery module are increased.\n\nThe battery module includes a circuit board (for example, a battery management unit (BMU)) electrically connected to the battery cell and configured to control the battery cell.",
