Abstract:
1. A lithium secondary battery unit set with a bus bar, comprising: a left end frame and a right end frame; a plurality of main frames having a first exposed tab support part formed at the top end thereof, the lower left of the first tab support part being formed with left receiving parts that are opened left and the lower right of the first tab support part being formed with right receiving parts that are opened right, and adjacently formed between the left end frame and the right end frame; a center frame having a second exposed tab support part formed at the top end thereof and having a left main frame fastened to the left thereof and a right main frame fastened to the right thereof to be mounted between the right receiving part of the left main frame and the left receiving part of the right main frame in two adjacent main frames among the plurality of main frames; a first type lithium secondary battery having a left electrode tab bent to the left of circumferential surface of a pouch and a right electrode tab bent to the right thereof, the first type lithium secondary battery is formed to be protruded and received in each left receiving part of a left group receiving part disposed to be adjacent to the left of a specific group receiving part including two receiving parts adjacent to each other among the plurality of left receiving parts and the plurality of right receiving parts and each left receiving part of a right group receiving part disposed to be adjacent to the right of the specific group receiving part; a second type lithium secondary battery having a left electrode tab having opposite polarity and formed to be protruded in a direction opposite to a right electrode tab of the first type lithium secondary battery and a right electrode tab having opposite polarity and formed to be protruded in a direction opposite to a left electrode tab of the first type lithium secondary battery and the second type lithium secondary battery being received in each right receiving part of the left group receiving part and each right receiving part of the right group receiving part; a first fastening member seated on the first tab support part to fixedly connect the right electrode tab of the first type lithium secondary battery and the left electrode tab of the second type lithium secondary battery in order to be conducted in series; a second fastening member seated on the second tab support part to fixedly connect the right electrode tab of the second type lithium secondary battery and the left electrode tab of the first type lithium secondary battery in order to be conducted in series; a left bus bar connected to the right electrode tab of the lithium secondary battery received in the right receiving part of the left group receiving part to be conducted to each other by a left bus bar fastening member seated on the tab support part disposed between the left group receiving part and the specific group receiving part; a right bus bar connected to the left electrode tab of the lithium secondary battery received in the left receiving part of the right group receiving part to be conducted to each other by a right bus bar fastening member seated on the tab support part disposed between the specific group receiving part and the right group receiving part; and an overcurrent circuit breaker connected to the left bus bar and the right bus bar in order to be conducted in series.
