Abstract
Systems, methods and software products comprising: providing cell measurement signals (CMs) associated with electrical energy storage component stack (CMs are referenced to ground potential (GP) at a local ground terminal (LGT)); providing via a first interface (FI) CM(s) as a first differential cell data signal (FDCDS) (wherein FI comprises differential terminals (DTs); providing FDCDS at a first winding (FW) of a first transformer (FT) connected to FI; establishing a coupling between GP and each terminal of FW via a bypass capacitor (BC) disposed between a DT and LGT; and referencing a center tap (CT) located between FT's winding terminals to LGT to establish a low-impedance coupling between CT and LGT, and isolate DC potential at LGT from DC potential of DTs. The low-impedance coupling is such that it reduces parasitic voltage drop at CT caused by high-frequency common-mode noise current due to noise signal transferred via parasitic capacitive coupling between FT's windings.
