Battery apparatus and manufacturing method therefor

A method of manufacturing a battery apparatus, the method comprising:

• forming a through-hole in a board;
• forming a conductive pattern on the board around the through-hole;
• forming a non-conductive layer on an inside surface of the through-hole;
• inserting a wire extending from a plurality of battery cells to an inside of the non-conductive layer of the through-hole;
• and
• forming a soldering part configured to connect the wire above the through-hole with the conductive pattern,
• wherein the soldering part and the conductive pattern are located at a first side of the board, and the wire is configured to be inserted into the board from the first side of the board towards a second side of the board located opposite to the first side of the board.

A method of manufacturing a battery apparatus, the method comprising:

• forming a plurality of through-holes in a board;
• forming a conductive pattern on the board around the plurality of through-holes;
• inserting each of a plurality of wires into a respective one of the plurality of through-holes from a respective one of a plurality of battery cells;
• and
• forming a plurality of soldering parts for the plurality of through-holes, each of the plurality of soldering parts connecting a respective one of the plurality of wires to the conductive pattern,
• wherein the conductive pattern is spaced by a predetermined distance from an outer circumference of the plurality of through-holes, and
• wherein the plurality of soldering parts and the conductive pattern are located at a first side of the board, and the plurality of wires are configured to be inserted into the board from the first side of the board towards a second side of the board located opposite to the first side of the board.
