摘要： The present invention relates to a parallel electrical connection structure for battery poles, a parallel battery bank, a battery pack, and a manufacturing method thereof. The parallel electrical connection structure mainly comprises a common adjusting busway and a plurality of electrically connecting branches, the two ends of each of the electrically connecting branches are configured to be electrically connected to the poles of the same polarity of the plurality of individual batteries and the common adjusting busway, the poles of the same polarity of different individual batteries are connected in shunt via the common adjusting busway and the electrically connecting branches, and the current carrying capacity of each electrically connecting branch is smaller than that of the common adjusting busway. With the present invention, any battery with thermal runaway in a new energy battery pack can be discovered and isolated as early as possible, and the development of the thermal runaway in the battery can be blocked as soon as possible, to avoid negative effects of the battery with thermal runaway on other normal batteries in the battery pack and ensure the normal operation of the battery pack.
