Battery charging arrangement

Claim 2

An arrangement for charging a battery in dependence on the load being supplied by the battery, comprising a first load connected with the battery; an additional load; A.C. generator means for charging the battery, and including first, second and third output windings; and switching means for connecting said additional load in circuit with the battery and automatically therewith connecting said windings in Y-formation, and for alternatively disconnecting said additional load from the battery and automatically therewith connecting said windings in series to form a single branch of a mesh including the battery so that one and the same current flows through said windings.

Claim 3

An arrangement as defined in claim 1; and further comprising rectifying means, connected between the battery and said windings, for permitting the flow Of current from said winding in only one direction through said battery.

Claim 4

An arrangement for charging a battery having a load, in dependence on the absence or presence of an additional load, comprising in combination A.C. generator means having a first, second and third winding, and each winding having a first and second end point, and wherein said first endpoints of said first and second winding are connected to a common point; first switching means connecting said first, second and third winding in Y-connection in the presence of said additional load and in series in the absence of said additional load, and being connected to said second end point of said second winding, said common point and said first end point of said third winding; rectifier means comprising a first, second and third rectifier element, and said first switching means comprising a first pair of contacts connecting said second end point of said second winding to said third rectifier element; means connecting said second end point of said first winding and said second end point of said third winding directly to said first and second rectifier elements respectively; additional-load switching means connecting said additional load when closed and disconnecting said additional load when open; means coupling said additional-load switching means to said first switching means in such a manner that said first switching means is operated in dependence upon the operation of said additional-load switching means, and wherein said first pair of contacts of said first switching means comprise contacts normally closed when said additional-load switching means is closed, and wherein said first switching means further comprises double-throw switching means connecting said first end point of said third winding to said common point when said additional-load switching means is closed and connecting said first end point of said third winding to said second end point of said second winding when said additional-load switching means is open.

Claim 5

An arrangement for charging a battery having a load, in dependence on the absence or presence of an additional load, comprising in combination A.C. generator means having a first, second and third winding, and each winding having a first and second end point, and wherein said first endpoints of said first and second winding are connected to a common point; first switching means connecting said first, second and third winding in Y-connection in the presence of said additional load and in series in the absence of said additional load, and being connected to said second end point of said second winding, said common point and said first end point of said third winding; rectifier means comprising a first, second and third rectifier element, and said first switching means comprising a first pair of contacts connecting said second end point of said second winding to said third rectifier element; means connecting said second end point of said first winding and said second end point of said third winding directly to said first and second rectifier elements respectively; additional-load switching means connecting said additional load when closed and disconnecting said additional load when open; means coupling said additional-load switching means to said first switching means in such a manner that said first switching means is operated in dependence upon the operation of said additional-load switching means, and wherein said first pair of contacts of said first switching means comprise contacts normally closed when said additional-load switching means is closed, and wherein said first switching means further comprises double-throw switching means connecting said first end point of said third winding to said common point when said additional-load switching means is closed and connecting said first end point of said third winding to said second end point of said second winding when said additional-load switching means is open.

Claim 6

An arrangement as defined in claim 3; further comprising voltage regulating means associated with said A.C. generator means.
