External hybridisation

The connector (16) contains circuitry designed so that an external energy source (30) connected to the connector exclusively supplies the electrical load (10) with energy in a low load range and supplies the load with energy in conjunction with the internal energy source (13) in an upper load range. The circuitry can be designed so that the external source charges a rechargeable internal source. Independent claims are also included for the following: (1) an electrical load with an inventive connector (2) and a method of supplying an electrical load with an internal energy source by hybridizing the internal source with an external source.
