Claim 55:
56. The apparatus of claim 1, further comprising:
one or more smart dual switching (“SDS”) devices, each including SDS circuitry in an SDS package constructed and arranged as a self-contained electronic switching device, the SDS package having a first switched terminal and a second switched terminal;
the SDS circuitry including:
a first electronic switch having a first control terminal, a first switched terminal, and a first common terminal,
a second electronic switch having a second control terminal, a second switched terminal, and a second common terminal,
a first SDS control circuit having an input connected to the first switched terminal, an input connected to the second switched terminal, and an output connected to the first control terminal, the first SDS control circuit being adapted to turn the first switch OFF: (i) while the second switch is ON; or (ii) if a current flowing between the first switched terminal and the first common terminal through the first switch satisfies a first pre-determined polarity, when a magnitude of the current through the first switch falls below a first pre-determined threshold; or (iii) if the polarity of the current through the first switch is opposite the first pre-determined polarity, after the first switch has been ON for a first pre-determined period of time; and
a second SDS control circuit having an input connected to the first switched terminal, an input connected to the second switched terminal, and an output connected to the second control terminal, the second SDS control circuit being adapted to turn the second switch OFF: (i) while the first switch is ON; or (ii) if a current flowing between the second common terminal and the second switched terminal through the second switch satisfies a first pre-determined polarity, when the current falls below a first pre-determine threshold; or (iii) if current flowing through the second switch between the second common terminal and the second switched terminal is opposite the second pre-determined polarity, after the second switch has been ON for a second pre-determined period of time; and

wherein the switch of each of the plurality of cell elements comprises a respective switch in a respective SDS device.
