Abstract:
A battery supply control for controlling current supplied from a battery to at least one load, comprising:an input for receiving a demand signal indicating when a current is demanded by the at least one load; a first relay, disposed between the battery and the at least one load, capable of substantially passing the current demanded by the at least one load when the first relay is closed; a second relay, connected in parallel to the first relay, capable of passing a fraction of the current demanded by the at least one load when the second relay is closed; and a controller for closing the first and second relays when the demand signal indicates the at least one load demands the current, such that the current is supplied to the at least one load, and for opening the first relay and maintaining the second relay closed when the demand signal indicates the at least one load does not demand current, such that the fraction of the current is supplied to the at least one load.
