Connection assembly and electrical energy storage device

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a novel connection arrangement for electrical energy storage devices, such as batteries. The arrangement uses two pole tabs held together between specially shaped clamping elements, and a clamping mechanism (such as screws or other means) that applies pressure to ensure a secure and low-resistance electrical connection. The key innovation is that the pole tabs are mechanically clamped without the need for destructive processes like welding or piercing, making the connection easily reversible and maintenance-friendly. This system is designed to improve reliability, facilitate replacement of individual cells or components, and minimize electrical resistance at the connection points.

Patent Abstract

The invention relates to a connection arrangement for an electrical energy store, comprising two pole lugs and two clamping elements as well as a clamping means, wherein the pole lugs are arranged at least in some sections between the clamping surfaces so as to adjoin each other in a planar manner, and the clamping means produces a clamping force which braces the first clamping surface and the second clamping surface against each other. The invention also relates to an electrical energy store comprising at least one such connection arrangement.
