Unit set having a plurality of lithium rechargeable batteries and a set having a plurality of the unit sets

A unit set having a plurality of lithium rechargeable batteries, comprising:

• a left end frame and a right end frame;
• a plurality of main frames which are arranged to be adjacent to each other between the left end frame and the right end frame, and which respectively have a first tap supporting portion formed at an upper end thereof to be exposed, a left space portion formed at a lower left side of the first tap supporting portion to be opened and a right space portion formed at a lower right side of the first tap supporting portion to be opened;
• a center frame which has a first tap supporting portion formed at an upper end thereof to be exposed, and of which a left side is coupled to a left main frame and a right side is coupled to a right main frame so as to be disposed between the right space portion of the left main frame and the left space portion of the right main frame of the two adjacent main frames;
• a first type lithium rechargeable battery which is formed with a left electrode tap bent to a left side of an outer circumferential surface of a pouch and a right electrode tap bent to a right side of the outer circumferential surface of the pouch and which is received in the left space portion of each main frame;
• a second type lithium rechargeable battery of which a left electrode tap having an opposite polarity of the right electrode tap of the first type lithium rechargeable battery is protruded in a direction opposed to the right electrode tap of the first type lithium rechargeable battery and a right electrode tap having an opposite polarity of the left electrode tap of the first type lithium rechargeable battery is protruded in a direction opposed to the left electrode tap of the first type lithium rechargeable battery, and which is received in the right space portion of each main frame;
• a first connecting means which is provided with a first lower fixing plate having a bolt protruded upward, a first upper fixing plate through which the bolt of the first lower fixing plate passes and a first coupling unit installed to an end of the bolt of the first lower fixing plate passing through the first upper fixing plate, and which is disposed at the first tap supporting portion;
• and
• a second connecting means which is provided with a second lower fixing plate having a bolt protruded upward, a second upper fixing plate through which the bolt of the second lower fixing plate passes and a second coupling unit installed to an end of the bolt of the second lower fixing plate passing through the second upper fixing plate, and which is disposed at the second tap supporting portion,
• wherein the right electrode tap of the first type lithium rechargeable battery and the left electrode tap of the second type lithium rechargeable battery received in one of the main frames are fixedly and electrically connected to each other in series by the first connecting means, and
• the right electrode tap of the second type lithium rechargeable battery received in the left main frame and the left electrode tap of the first type lithium rechargeable battery received in the right main frame of the two adjacent main frames are fixedly and electrically connected to each other in series by the second connecting means.
