| 摘要 |
The invention relates to a rechargeable battery unit, in particular for a watercraft, having a plurality of rechargeable battery elements (10) which are interconnected via a holding arrangement to form a rechargeable battery cell, said holding arrangement comprising at least one holder (20) forming receptacles (21.1, 22.1) by means of which the rechargeable battery elements are held in the region of a pole end. At least part of the rechargeable battery elements are electrically coupled to each other in the region of their poles (11, 12) by means of a pole connector (30). A structure of the above kind allows a powerful rechargeable battery unit which requires little space and the rechargeable battery cells of which can be cascaded for the purpose of variation in energy density and/or voltage. Said rechargeable battery unit is particularly suitable for use in motor-driven watercraft. |
