Modular electronically reconfigurable battery system
An electronically reconfigurable battery includes a number of battery modules selectively interconnected by a number of electronic switches, wherein a selectable number of battery modules may be connected either in a series configuration or in a parallel configuration, as a result of placing selected switches of said plurality of switches in open states or closed states. In a parallel configuration, the battery provides power to a primary load, such as a propulsion load for a vehicle. In a series configuration, the battery is configured to provide a high voltage and high power output to a short-term and/or pulsed load, such as an additional load provided on the vehicle.
1. An electronically reconfigurable battery, comprising:
a first plurality of battery modules configured in a star configuration;
a plurality of switches interconnecting said plurality of battery modules such that a selectable number of said plurality of battery modules may be connected in at least one of a series configuration and a parallel configuration, as a result of placing selected switches of said plurality of switches in open states or closed states; and
an output switch for connecting a first output terminal of said battery to a first load.
2. An electronically reconfigurable battery as recited in claim 1 , wherein each of said plurality of battery modules is coupled with at least three of said plurality of switches as follows:
a first switch which connects said each battery module in series with an adjacent battery module when closed, and
second and third switches which connect said each battery module in parallel with an adjacent battery module when closed, wherein when said first switch is closed, said second and third switches are open, and when said first switch is open, said second and third switches are closed.
3. An electronically reconfigurable battery as recited in claim 1 , further comprising:
a second plurality of battery modules, each of said second plurality of battery modules being connected in parallel with each other, said first plurality of battery modules being selectively connected to said second plurality of battery modules through at least two of said plurality of switches.
