A fail signal indicating overcharge/overdischarge of unit cells detected by voltage detecting ICs ( 21 - 1 ) to ( 21 - n ) is transmitted as a digital signal and an analog signal to a CPU 32. If the analog fail signal and digital fail signal agree with each other, the CPU 32 determines that overcharge or overdischarge is occurring in the unit cells. If the fail signals disagree with each other, it is determined that an error is occurring in data communication in communication lines L 1 to L 3 and the error is informed to an operator with an alarm signal or the like. As a result, overcharge or overdischarge is highly accurately detectable.

A new battery cell structure uses a reduced stack pressure force to be used and applied over a much smaller area of the cells by using the sides of the cell instead of the top and bottom of the cell. To reduce the amount of force required to compress a cell, an edge-wise construction can be used instead of the sheet construction. Instead of stack pressure having to be applied to the top and bottom of the cell, it is now applied across the edges. An edge-on design is used to form strips, which allows for flat sides of a battery body. 1. A battery using reduced stack force and edge-wise construction , comprising:a first edge plate having substantially a length and substantially a width;a second edge plate having substantially the length and substantially the width; a cathode current collector layer;', 'a cathode material layer coupled to the cathode current collector layer;', 'an anode current collector layer;', 'a Lithium-metal layer coupled to the anode current collector layer and comprising Lithium metal; and', 'a separator layer disposed between the Lithium-metal layer and the cathode material layer and configured to insulate the cathode material layer from the Lithium-metal layer; and, 'one or more sets of layers compressed with pressure between the first edge plate and the second edge plate, the sets of layers having substantially the length and substantially the width, a set of layers from the one or more sets of layers comprising an edge of the battery is defined by the length and the width of the one or more sets of layers within the battery; and', 'a side of the battery is defined by the length and the depth of the one or more sets of layers within the battery,', 'wherein an edge area of the battery body is larger than a side area of the battery body., 'a battery body having the length, the width and a depth, wherein2.
