A large battery array, particularly for use in an electric vehicle, is formed of multiple modules, each containing plural battery cells and module management electronics. Each battery module has a nominal output voltage in the range of about 5 volts to about 17 volts. A controller communicates with individual battery modules in the array and controls switching to connect the modules in drive and charging configurations. The module management electronics monitor conditions of each battery module, including the cells it contains, and communicates these conditions to the controller. The module management electronics may place the modules in protective modes based upon the performance of each module in comparison to known or configurable specifications. The modules may be pluggable devices so that each module may be replaced if the module is in a permanent shutdown protective mode or if a non-optimal serviceable fault is detected.

Particles emitted by radio-isotopic by-products of nuclear fission are used as a power source at the cathode of a magnetron system. Particles include high energy electrons having a large associated EMF. In the system a radial electrical vector E, between the cathode and anode, interacts with an axial magnetic vector B vector to produce an E×B force that rotates the particles about the system axis. These emissions are within a set range of velocities. The angular velocity and geometry of a rotating field, known as a space charge wheel (SCW), may be modulated by an external RF inputs to cavities of an anode block and the use of concentric biasing grids between the cathode and anode block. The SCW induces LC values into cavities of the anode, exciting them and producing electrons resonance which may be used to generate power.
