摘要： A battery charging system with enhanced time-based charging and coupling detection, as well as battery health monitoring and battery cell selection. A user provides a time available for charging to the vehicle or a mobile device and indirectly to a charging station, or the charging station directly. The time available for charging, as well as battery health information, is shared with the charging station when the charging station detects coupling of the associated connector/coupler to the vehicle, or when the vehicle is detected within a predetermined proximity of the charging station. Subsequently, a standard charging power may be utilized or a charging power may be selected and utilized such that enhanced or optimized charging can be provided for the available time period. A battery control unit identifies degraded or faulted battery cells and charging of these battery cells is avoided or deprioritized.

摘要： Disclosed is an apparatus and method for controlling an operation of a secondary battery using a relative deterioration degree of an electrode. The method includes determining a SOC of the secondary battery whenever a pulse current flows through the secondary battery; determining an electrochemical reaction resistance from a voltage change amount measured during a preset initial time in each pulse current section and determining a lithium ion diffusion resistance from a voltage change amount measured during a remaining time except for the initial time; determining a deterioration-biased electrode by comparing a deterioration diagnosing resistance ratio, which is a relative ratio of the lithium ion diffusion resistance to the electrochemical reaction resistance, with a preset reference deterioration diagnosing resistance ratio; and adaptively adjusting an operation condition of a next charging/discharging cycle according to the type of the deterioration-biased electrode.

摘要： A system in a vehicle includes memory to store driving history and charging history of the vehicle. The system also includes a processor to obtain a predicted battery life of one or more battery packs of the vehicle based on the driving history and the charging history, obtain a targeted battery life of a user indicating a mileage goal for a specific charge capacity of the one or more battery packs, and determine a difference between the predicted battery life and the targeted battery life. The processor solves an optimization problem to determine a future charging strategy to achieve the targeted battery life and controls an onboard charging system or an external charger based on the future charging strategy or controls routing or navigation based on the future charging strategy.

摘要： 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.

摘要： Electric vehicle predictive range estimating systems and methods are provided herein. An example method includes determining an initial state of charge (SOC) for an energy source of a vehicle at a first point in time; determining one or more boundary conditions for the vehicle during a time frame extending from the first point in time to a second point in time, the one or more boundary conditions causing a loss in the energy source during the time frame; determining a predicted future SOC for the energy source based on the one or more boundary conditions and the initial SOC; and predicting an availability of a vehicle operating condition based on the predicted future SOC for the energy source.
