Embodiment Construction

[0053] figure 1 A known contact crown K is shown. The contact crown K has a circular base B, on the periphery of which six contact lugs F are evenly distributed. In the middle of the base B, a downwardly offset contact surface KF is arranged.

[0054] The illustrated contact crown K can be produced, for example, as a stamped and bent part. Electrical contacting to the positive pole of the battery cell can be achieved by connecting the contact surface KF to the positive pole. The negative pole of the battery cell can be contacted by pushing the contact lug F on the housing of the battery cell.

[0055] If several negative poles are to be connected in parallel, a corresponding number of contact crowns K with contact surfaces KF must be arranged on the electrically conductive carrier.

[0056] figure 2 shows a diagram of a known current rail S that is required to operate with a figure 1 The contact crown K is an electrical contact in parallel with the positive pole of the ...

Abstract

The invention relates to a cell contact device (100, 200, 300) for the electrical contact of battery cells, comprising: a contact crown (101, 102, 103, 104, 201, 301) for each battery cell, each contact crown (101, 102, 103, 104, 201, 301) having a contact base (105), on the outer periphery of which at least two opposing contact lugs (106, 107, 108, 109, 110, 111, 112, 113); and a number of connecting tabs (115, 116, 177), each connecting two of the contact crowns (101, 102, 103, 104, 201, 301) arranged next to each other, the contact lugs (106, 107, 108, 109, 110, 111, 112, 113) being arranged on the outer periphery of said contact base (105) and forming a free channel (118) arranged in each two adjacent contact crowns (101, 102, 103, 104, 201, 301) and above the corresponding connectingpiese (115, 116, 117). Furthermore, a battery system (350) is disclosed.

Description

technical field [0001] The invention relates to a cell contacting device for electrical contacting of battery cells. The invention also relates to a corresponding battery system. Background technique [0002] In the following, the invention is mainly described in connection with an electric drive for a vehicle. However, it is understood that the invention can also be used in other applications, for example in static energy stores. [0003] In the case of electrochemical energy storage systems such as batteries, the desired voltage level is achieved by connecting individual electrochemical cells in series. Multiple units can be combined into individual modules. Typically the desired voltage is generated by a corresponding row of modules with a corresponding number of battery cells. [0004] A typical field of use for such energy storage systems is electric mobility, in particular electric vehicles, but their use is not limited thereto. The electric motor used to drive th...
