Abstract: A system is provided for performing a power estimation process for an electric vehicle using a controller. The controller estimates an inner state of an energy storage supply of the electric vehicle. The inner state represents a state-of-charge (SOC) and/or a state-of-health (SOH) of the energy storage supply. The controller also estimates an SOC value and/or an SOH value of the energy storage supply based on at least one of: a present current level, a present voltage level, a present temperature, and time-based information. The controller further estimates a bounded SOC value based on the SOC value, a first upper bound, a the first lower bound, and/or estimates a bounded SOH value based on the SOH value, a second upper bound, and a second lower bound. The controller then controls an electrification process of the electric vehicle based on the bounded SOC and/or SOH values.

Abstract: 3-D magnesium voltaic cells have a magnesium anode coated on multiple opposing surfaces with a continuous protective/electrolyte layer that is ionically conductive and electronically insulating. The resulting protected 3-D magnesium anode is coated on multiple opposing surfaces with a continuous cathode layer that is electronically and ionically conductive, and includes a magnesium storage medium. Suitable magnesium anodes, in particular, magnesium foam anodes, can be made by pulsed galvanostatic deposition of magnesium on a copper substrate. The protective layer can be formed by electropolymerization of a suitable methylacrylate ester. The continuous cathode layer can be a slurry cathode having powders of an electronic conductor and a reversible magnesium storage component suspended in a magnesium electrolyte solution.
