Parallel connection assembly of batteries and battery set having the same

A battery set, including:

• a plurality of battery units each having a positive electrode hole and a negative electrode hole, and
• a parallel connection assembly, comprising:
• a plurality of electrical-conductive connecting pieces each having a through-hole and a fixing portion, the electrical-conductive connecting pieces being aligned with the positive electrode holes and the negative electrode holes respectively;
• two flexible metallic woven bands serially connecting the fixing portions of the electrical-conductive connecting pieces located on the positive electrode holes and the negative electrode holes respectively;
• and
• a plurality of electrical-conductive fixing elements passing through the through-holes to be fixed in the positive electrode holes and the negative electrode holes, so that the two flexible metallic woven bands can electrically connect the battery units in parallel,
• wherein each of the battery units includes a casing, the positive electrode hole and the negative electrode hole are provided on a top surface of the casing, each of the positive electrode hole and the negative electrode hole is an inner threaded hole made of electrical-conductive metal, the through-hole of each electrical-conductive connecting piece is disposed on the top surface of the casing of the battery unit to be aligned with the positive electrode hole or the negative electrode hole, and
• wherein each of the electrical-conductive connecting pieces is made of electrical-conductive metal and comprises a piece body, the through-hole and the fixing portion are formed on the piece body, the fixing portion comprises a stopping wall extending upwards from the piece body and two pressing strips bending from two opposite sides of the stopping wall, the flexible metallic woven band passes through a space between the stopping wall and the two pressing strips to be clamped by the two pressing strips.
