摘要： Methods and systems for determining a state of charge of a battery are provided. A first component of the state of charge is calculated based on a first property of the battery. A second component of the state of charge is calculated based on a second property of the battery. The first component of the state of charge is weighted based on a rate of change of the first property relative to a change of the state of charge. The second component of the state of charge is weighted based on a rate of change of the second property relative to a change of the state of charge. The state of charge is determined based on the first and second weighted components.

摘要： A method for determining a diffusion voltage in an electrochemical cell (e.g., a battery used in connection with an automotive vehicle) includes estimating a previous diffusion voltage, calculating a new diffusion voltage using an equation based on a diffusion circuit model and the previous diffusion voltage, and setting the previous diffusion voltage equal to the new diffusion voltage. The step of calculating the new diffusion voltage may then be repeated.

摘要： The present invention in one form provides for an improved battery charging apparatus and method comprising a controller and battery balancing system including an algorithm which monitors temperature of the battery pack and state of charge. These are factored for a charge efficiency through comparison to a pre-determined table of charge efficiency values, and then compared against a threshold charge efficiency below which charging is considered not optimal. The charging operation is discontinued in the event charge efficiency is below the threshold value.

摘要： The present invention includes a microelectrode which achieves a surface-renewal advantage. The sensor and method directly controls the oxidizing and reducing nature of the electrode interface by controlling the cell potential, thereby protecting the sensing electrode's surface during periods in which the sensor is not being used. The microelectrode is biased at a small positive potential relative to the counterelectrode, except when a measurement is desired. To measure oxygen concentrations in brake fluid, the microelectrode is biased at a greater potential and the current is measured. After the current measurement, the potential is returned to the small positive potential. The oxygen concentration (and thus the amount of air) in the brake fluid is linearly related to the current measured.

摘要： A magnetic sensor for measuring the magnetic properties of a battery cell, and converting the magnetic properties to a battery cell SOC. The magnetic sensor includes a magnetic core formed of laminated high permeability plates provided in a C-shape. An extended portion of the battery cell extends through a transverse opening in the core so that it is positioned within the core. A driving coil is wrapped around one end of the magnetic core and generates a magnetic field in the core that extends across the transverse opening and through the battery cell. A receiving coil is wrapped around an opposite end of the core that receives the magnetic field, and converts the magnetic field to a representative current. A detection circuit converts the receiving coil current to the battery cell SOC.

摘要： A method and system for use with a vehicle battery pack having a number of individual battery cells, where the method estimates, extrapolates or otherwise determines individual cell resistances. According to an exemplary embodiment, the method and system use a voltage and temperature reading for each of the individual battery cells, as well as a voltage and current reading for the overall battery pack to determine one or more cell resistance values, such as a minimum and maximum cell resistance for the battery pack. This approach relies upon temperature deviations in the battery pack to make assumptions or estimates regarding individual battery cell resistances. By having individual cell resistance values—instead of using an overall pack resistance value and building in a buffer to account for cell variations—better and more accurate cell-level data can be obtained that, in turn, can improve charging, discharging, cell balancing and/or other battery-related processes.
