Claim 0:
1. A battery pack, comprising:
a plurality of series battery banks, each of the series battery banks is formed by arranging a plurality of individual batteries having a series busbar side by side, wherein each of the individual batteries comprises a first pole and a second pole, the first pole and the second pole are the two electrical poles of the individual battery; the first poles and the second poles of adjacent individual batteries are electrically connected to two ends of the series busbar respectively;
at least the first poles of the plurality of individual batteries adjacent to each other in different series battery banks are connected in shunt via a parallel electrical connection structure for the battery poles to form an external first pole of the battery pack, and at least the second poles of the plurality of individual batteries adjacent to each other in different series battery banks are connected in shunt to form an external second pole of the battery pack; the parallel electrical connection structure for battery poles comprises a common adjusting busway and a plurality of electrically connecting branches; each of the electrically connecting branches has a first end and a second end; the first end of each electrically connecting branch is configured to be electrically connected to the first pole of one individual battery in a different series battery bank, and the second end of each electrically connecting branch is electrically connected to the common adjusting busway, so that a plurality of the first poles of the plurality of individual batteries adjacent to each other in a row in a transverse direction are connected in shunt; the common adjusting busway and the electrically connecting branches are insulated, except that the first ends of the electrically connecting branches are electrically connected to the first poles of the individual batteries; a current carrying capacity of the common adjusting busway is greater than or equal to a sum of the current carrying capacities of n−1 electrically connecting branches, where n is the number of electrically connecting branches electrically connected to the common adjusting busway; and when thermal runaway happens in an individual battery connected to the electrically connecting branch, the electrically connecting branch will be fused and burnt, so that the individual battery is electrically isolated from the parallel battery bank in which the individual battery is situated.
