Embodiment Construction

[0033] exist figure 1 A battery 1 with 22 battery cells 2 is shown in . The battery 1 has a carrier plate 4 consisting of a plurality (here four) of carrier plate elements 6 as well as a front current output element 8 . 1 and a rear current output element 8 . 2 .

[0034] In this embodiment, the battery 1 is provided with 11 strings and 2 parallel connections, that is, every two adjacent battery cells 2 are connected in parallel with each other, and 11 such adjacent battery cells connected in parallel are connected in series with each other. In other, not described, exemplary embodiments, a circuit of the same type with another number of battery cells or another number of battery cells connected in parallel to one another, as well as a purely series connection, are of course also conceivable.

[0035] Furthermore, the battery 1 has a power outlet socket 10 for connection to other batteries and / or power consumers.

[0036] On the carrier plate 4 and thus also on the individua...

Abstract

The invention relates to a carrier board element (6) for the cell connectors (18) of a battery (1) having a plurality of battery cells (2), said carrier board element having a plurality of cell holders (14) uniformly spaced apart from each other, wherein at least one locking element (16) for the locking in of a cell connector is associated with each of said cell holders, which locking element is arranged on the carrier board element, wherein a plurality of cell connectors can be captively locked in one over the other at the locking elements.

Description

technical field [0001] The invention relates to a carrier plate element for a cell connector of a battery with a plurality of battery cells; the invention also relates to a carrier plate with a plurality of such carrier plate elements and a A battery of multiple battery cells and such a carrier plate. Background technique [0002] Lithium-ion battery modules (also called batteries below) and some other batteries used in hybrid and electric vehicles are composed of multiple battery cells that pass through metal cell connectors (also called bus bars) are electrically connected to each other. [0003] Depending on the desired driving power and / or operating voltage, in terms of the number of installed battery cells (also called module size), in terms of electrical wiring (eg pure series, series / parallel) and / or in terms of possible These batteries can differ from one another in terms of achieved current carrying capacity (also called power class). [0004] The challenge in pr...
