Battery array and battery pack having the same

摘要

A battery array includes: a plurality of batteries arranged into 2N+1 bundles, each of the bundles including M+1 batteries of the batteries arranged in parallel (where N and M are natural numbers); a plurality of connection tabs arranged at a first end of the battery array and at a second end of the battery array, each of the connection tabs being coupled to a corresponding pair of the bundles to electrically couple a first bundle through a 2N+1th bundle of the bundles in series; a first output terminal having a first polarity, and electrically coupled to the first bundle; and a second output terminal having a second polarity, and electrically coupled to the 2N+1th bundle, the second output terminal being adjacent to the first bundle.

1. A battery array comprising:
a plurality of batteries arranged into 2N+1 bundles, each of the bundles comprising M+1 batteries of the batteries arranged in parallel, where N and M are natural numbers, and each of the batteries has a positive terminal and a negative terminal opposite the positive terminal; a plurality of connection tabs arranged at a first side of the battery array and at a second side of the battery array, each of the connection tabs being coupled to a corresponding pair of the bundles to electrically couple a first bundle through a 2N+1th bundle of the 2N+1 bundles in series; a first output terminal having a positive polarity, and connected to the positive terminal of each of the batteries of the first bundle; a second output terminal having a negative polarity, and connected to the negative terminal of each of the batteries of the 2N+1th bundle, a case enclosing the batteries, the connection tabs, and the first and second output terminals; and a holder case between each of the bundles and the case, wherein the 2N+1 bundles are arranged to have:
the first bundle through the 2N+1th bundle arranged in a closed curve,the first bundle and the 2N+1th bundle at end bundles of the electrical series and the closed curve,the positive terminal of each of the batteries of the first bundle and the positive terminal of each of the batteries of the 2N+1th bundle at the first side of the battery array,the negative terminal of each of the batteries of the first bundle and the negative terminal of each of the batteries of the 2N+1th bundle at the second side of the battery array,at least one of the batteries of the first bundle adjacent to at least one of the batteries of the 2N+1th bundle, andthe second output terminal adjacent to the first bundle.
