Electric vehicle (EV) battery performance near end of life is limited by mismatched cell
degradation, leading to an estimated 5-10% cell capacity variation across the pack. Active …

As electric vehicles compete with internal combustion engine cars, cost and weight savings
remain central research objectives. The auxiliary power module, a dc/dc converter …

A distributed switch matrix is proposed that enables balancing of series-connected groups of
battery cells in a pack through dc-dc converters. The switch matrix is used to develop a multi …

In this report the development of a battery-system model, and a battery balancing algorithm
that is used for the system at hand are discussed. Both these topics are discussed in the …

In this paper a novel Hierarchical MPC (H-MPC) control scheme for active cell balancing is
introduced. This control scheme is applied to a battery system consisting of multiple …

Abstract Providing degraded Electric Vehicle (EV) batteries with a second-life when they no
longer meet vehicle energy and power requirements has the potential to increase the value …

In battery systems, the electrical connections between the voltage nodes and battery
management system are typically implemented with a single wire per node to limit the …

The present disclosure provides electrical architecture for electrochemical impedance
spectroscopy (EIS). An EIS circuit comprises at least two current regulators and an electrical …
