Claim Text:
1. A vehicular electrical system including an engine starting portion and a non-engine starting portion, said electrical system comprising: a main and a secondary battery, said main battery is non-switchably connected to an engine starting portion of a vehicular electrical system, said secondary battery is non-switchably connected to a non-starting portion of said vehicular system; a battery switch that, in a first switch state, is configured to connect said main and said secondary batteries and their respective loads in parallel in response to a first signal waveform, and, in a second switch state, is configured to isolate said first and second batteries and their respective loads from each other in response to a second signal waveform, wherein said signal waveforms are received via a switch control input port; a wave shaping network connected to said switch control input port, said wave shaping network comprises a separate first waveform shaping portion and a separate second waveform shaping portion; a charge switch, configured to switchably connect an electrical charge source to said first waveform shaping portion of said wave shaping network, wherein switch state of said charge switch is controlled by an externally applied command signal; a discharge switch, configured to switchably connect a charge sink to said second waveform shaping portion of said wave shaping network, wherein switch state of said discharge switch is controlled by said externally applied command signal.
