1. A battery charger comprising:
- a plurality of electric power sources created from a main electric power feed;
means to deliver power from said plurality of electric power sources to a battery;
means to select a combination of said plurality of electric power sources;
a logic device controlling said source selection means;
means to provide status information of said battery to said logic device;
means to provide identification of said battery to said logic device.

Abstract
In a first embodiment multiple power sources are selected and then combined. Selecting power rather than controlling power may be a cheaper way of controlling the amount of power delivered. In a second embodiment the logic to control power is removed from the battery charger so that the logic may be changed when a different battery is being charged. This permits all types of batteries to be charged if the power source is compatible with the battery. Other embodiments expand the types of power sources that may be used.

2. A battery controllable charger comprising:
-
means to create a controllable electric power source from a main power feed; means to deliver power from said controllable electric power source to a battery being charged; means to provide a first battery status information about a battery to a first logic device; said first logic device controlling said controllable electric power source so said controllable electric power source provides an acceptable charging power to a first battery based on said first battery status information; means to replace said first battery with a second battery;
said first logic device controlling said controllable electric power source so said controllable electric power source provides power that damages said second battery;means to replace said first logic device with a second logic device; said second logic device controlling said controllable electric power source so as to deliver an acceptable charging power to said second battery based on said second battery status information. - View Dependent Claims (6)
