A device for electrical interconnection of cells of a battery pack through cell connectors, and a battery pack having the device and the cell connectors are provided. A plurality of cell connectors for connection of at least two cell poles are fitted on a mounting plate, electrically isolated from one another. Each cell connector has at least one flexible bracket which extends away from a connection area. The flexible brackets are coupled to the connection area through a resilient structure having a meandering shape.

Device for electrically interconnecting cells in a battery pack by means of cell connectors and battery pack with such cell connectors

The present invention refers to a high-voltage battery for power supply, particularly of an automotive vehicle, comprising: an energy storage module with a plurality of electrochemical storage cells and a wall accommodating the plurality of storage cells, each storage cell comprising at least two electric connection terminals, and an upper part for contacting and covering the connection terminals, said upper part overlapping the wall in a contactless manner, so that a gap remains relative to the storage cells.

High-voltage storage device

The present invention relates to a cell contacting arrangement for an energy storage module having a plurality of electrochemical storage cells, each storage cell having at least two electric connection terminals, the arrangement comprising: a carrier plate which is mountable on the energy storage module, and at least one cell connector inserted into the carrier plate for connecting at least two of the connection terminals of different storage cells, the carrier plate comprising at least one catch spring having a detent for fixing the cell connector in the carrier plate.

Cell contacting arrangement for an energy storage device

In order that even the cell connectors () of, for instance, a traction rechargeable battery () which carry very high currents can be connected to a battery management system () in a fault-resistant and functionally reliable manner, firstly a circuit board () in the form of a leadframe () encapsulated with plastic by injection molding is latched onto the housing () mechanically grouping the cells (), said circuit board in any case not projecting higher than the adjacent end faces () of the cell terminal connections () projecting at a clear radial distance therefrom. When a cell connector () is placed onto the terminal connections (), it descends with a nozzle () extending in a manner curved away therefrom into the plane of the leadframe () parallel to the cell connector (), and in the process becomes wedged between at least two clamping lugs () facing one another, whereby an extremely reliable mechanical and electrical connection of the cell connector () to the wiring circuit board () is produced.
