Connection of power supply to a control circuit for an antitheft battery

摘要

In the lid (1) of a battery an anti-theft device is provided comprising a switch device (15) and control circuits encapsulated in a block (13). In order to provide a good heat dissipation from the switch device (15) it is in direct contact with metal plates (45) attached to terminals (37) in individual battery cells. These terminals are located at the same long side of the battery as the external terminals (3, 5) and it is achieved by a special connection of the individual battery cells. From the outermost terminal pole pieces (55) extend in to longitudinal channels (57) which in turn extend up to the cavity for the switch device (15) and the control circuits. In the channels (57) electrical leads (59) extend to the block (13) and the control circuits located therein and in particular to a power supply unit.
