A circuit arrangement, in particular for an electrically driven motor vehicle

A circuit arrangement (1), in particular for an electrically driven motor vehicle, has at least one bus bar (5) which is connected electrically to a supplier (2) and which is connected to a first consumer (3) at a first transfer point (6) and to a second consumer (4) at a second transfer point (7). Both the first and the second transfer point (6, 7) are formed as flexible contact points.

Disclosed is a printed circuit board having a holder for a battery, wherein the holder includes first and second contacts connected to conductive traces of the printed circuit board and wherein the holder is embodied such that a battery inserted into the holder is clamped so that poles of the battery on opposite end faces of the battery make electrical contact with the first and second contacts. The battery lies clamped between the contacts on a support region of the printed circuit board and is oriented with reference to the printed circuit board so that an imaginary line connecting the poles of the battery is essentially in parallel with the plane of the support region. The printed circuit board has connected with the support region a rigid first section, which is essentially perpendicular to the support region, and wherein the first contact is arranged on the first section.

A battery pack wherein each battery is mechanically and electrically connected by a magnetic device to a busbar. In case of failure of any accumulator, it is disconnected completely passively because its failure generates an inactivation of the magnetic device. The disconnection causes the gravity drop of the accumulator and the possibly completely passive implementation of an accumulator shunt.

The invention relates to a process for manufacturing a roll of flexible carrier bearing electronic components. This process includes a step consisting in adding, to this flexible carrier, electronic components, themselves manufactured from a roll of flexible initial substrate. For example, the electronic components may be manufactured on an initial substrate having a width allowing advantage to be taken of densification of the manufacture of the components on this initial substrate. Subsequently, the singulated electronic components are added to the flexible carrier, allowing, for example, packaging that is more suitable, than possible with the initial substrate, to a use of the electronic components, notably when the latter must be integrated into a chip-card. Thus, for example, the flexible carrier may be, or include, an adhesive, which may or may not be conductive, and which is used to fasten, and optionally connect, each electronic component to a chip-card.

A method for assembling a battery module including a unified connection array with a flexible connector is described. The flexible connector can include a plurality of pads that are secured to a central spine. The flexible connector may be a single piece connector. The flexible connector can include monitors that are mounted to the flexible connector to gather data regarding battery cells of the battery module.
