Method and system for improved state estimation accuracy in battery management systems with cell balancing
When balancing cells in battery packs, the voltage induced by the balancing current across the parasitic wire resistance distorts the measured cell voltage, leading to inaccurate cell state estimation. A method and battery management system to extract a parasitic resistance of battery connection wires connecting a cell of a battery to a cell balancing circuit is disclosed. The parasitic wire resistances for a battery pack are extracted through the coordinated operation of a pack-level current source and cell-level balancing circuit. A voltage drop is imposed and measured across the parasitic resistances while maintaining zero current in the immediate battery cell. Maintaining zero current in the immediate battery cell avoids possible extraction error resulting from voltage drop across the battery cell impedance due to battery cell current flow.

This application is directed to approaches for addressing technical problems that arise due to common-mode (CM) leakage currents. CM leakage currents may or may not be present depending on grid architecture, and if not addressed, can lead to operational issues relating to electrical safety mechanisms (e.g., nuisance tripping).

An integrated charging topology is introduced for drivetrain solutions operating split-phase machines with variations are proposed both for single phase and multi phase variants. An active power decoupling variant is introduced using a single-input space vector decomposition and the usage of a power ripple phasor. This variant approach enables closed-loop control of the harmonic output power ripple (e.g., second harmonic), compensating for unmeasured effects, such as the interfacing inductance periodic energy storage, and allowing for a near-total reduction in the experimental setting. In operation, the control approach can include controlling the average power transfer between the grid and the battery and/or attenuating a second harmonic power ripple.

Abrégé
The present disclosure provides electrical architecture for electrochemical impedance spectroscopy (EIS). An EIS circuit comprises at least two current regulators and an electrical energy storage device, which are connected with one or more electrochemical cells in a configuration that decouples power flowing into the respective current regulators. The presence of the electrical energy storage device enables each regulator to operate simultaneously at lower power levels while inducing the desired EIS perturbation current. Operation at low power allows lower volume and cost for the same current compared to only dissipative or non-dissipative current regulators. Further, the electrical energy storage device allows the power flowing through the current regulators to be varied independently in order to achieve the desired EIS perturbation current while a minimum amount of heat is generated in the circuit, thus allowing the circuit to occupy minimal size and incur minimal cost.

Integrated three-phase AC charger for vehicle applications with dual-inverter drive
A powertrain for electric and plug-in hybrid vehicle applications with integrated three-phase AC charging featuring buck-boost operation and optional vehicle-to-grid (V2G) capability, along with corresponding methods and machine instruction sets for switch control. The powertrain can include of a three-phase current source converter (CSC) front-end with an associated input filter, a polarity inversion module, and in an embodiment, a dual-inverter motor drive. The dual-inverter drive is the source of both the back emf and requisite DC inductance for the CSC. A compact design is thus provided as no additional magnetics are required and the on-board cooling system required for traction mode can be re-deployed for charging and V2G mode. The powertrain is mode shifted between charging and V2G mode through an optional polarity inversion module.
