Abstract
Reconfiguration of a rechargeable energy storage system into two or more new capacitor or battery or fuel cell packs arranged in “connections”, e.g. series or parallel strings. Each pack of rechargeable energy storage devices includes rechargeable energy storage modules. In each rechargeable energy storage module, which can include one or more capacitors or fuel cells or battery cells, there is arranged a network of banks of switches. A first bank of switches is arranged to connect a rechargeable energy storage module in a first series connection string with other rechargeable energy storage modules. A second bank of switches is arranged to connect a rechargeable energy storage module in a second connection string with other rechargeable energy storage modules. A first bypass switch is arranged to exclude a rechargeable energy storage module from the first series connection string when the first bypass switch is activated.
