A battery charging and electrical energy delivery system (25) that allows for separation of charging of a battery (23) and delivery of electrical energy to a first set of consumers (24). The battery may be charged via a first path (29) for connecting the battery with an energy source (22), while electrical energy may be supplied via a second path (30) (separate from the first path) from the energy source to the first set of consumers. The first set of consumers may also be powered by the battery via third path (31) e.g. if the energy source is off. A control unit (32) is adapted to control the supply of electrical energy along the first, second and third paths in response to a detected state of the energy source. A battery operated system (21a) including the battery charging and electrical energy delivery system (25) is also provided.
