Abstract
Abstract A method and apparatus for interconnecting one or more groups of primary electric cells in which cells in each group are further divided into two series-connected subgroups which, in twin, are connected to a three-conductor transmission system having a positive, a negtive and a neutral or return conductor. One subgroup of each group is connected between the negative terminal and the neutral and the other subgroup is connected between the positive terminal and the neutral such that the line to line voltage is twice that of the line to neutral voltage similar to a three-wire traditional AC supply system.
