Accumulator arrangement, busbar element therefor and method for producing an accumulator arrangement

A method, comprising:

• a) providing a plurality of individual accumulators which are to be connected together in series,
• b) affixing an electrical connection line or an electrical connection module to a first terminal post of a first individual accumulator of the plurality of individual accumulators which are to be connected together in series,
• c) affixing a first busbar element of a plurality of busbar elements to a second terminal post of the first individual accumulator and to a third terminal post of a second individual accumulator of the plurality of individual accumulators in the series connection,
• d) affixing a second busbar element of the plurality of busbar elements to a fourth terminal post of the second individual accumulator and a fifth terminal post of a third individual accumulator of the plurality of individual accumulators in the series connection, such that the first busbar element is at least partially covered by the second busbar element,
• e) repeating step d) until a final individual accumulator of the plurality of individual accumulators in the series connection is connected to a second-to-last individual accumulator of the plurality of individual accumulators by a third busbar element of the plurality of busbar elements, and
• f) affixing an additional electrical connection line or an additional electrical connection module to a sixth terminal post of the final individual accumulator,
• wherein the first busbar element or the second busbar element is affixed in step c) and/or d) as follows:
• i) mechanically coupling an insulating cap of the first busbar element or the second busbar element to an adjacent busbar element of the plurality of busbar elements by means of at least one additional fixing means provided on the insulating cap of the first busbar element or the second busbar element, and
• ii) affixing a connector element of the first busbar element or the second busbar element to the terminal posts with terminal post fixing means manipulated through openings of the insulating cap by a tool, and
• wherein a pivoting motion occurs after step i) and prior to step ii) to bring the first busbar element or the second busbar element into an assembly position before step ii) can even be performed.
