Patent number: 10393812Abstract: A method for estimating state-of-charge of a battery cell includes suppressing full execution of a capacitance-estimation algorithm for as long as a parameter does not exceed a certain threshold. The parameter is either a measured voltage value across the cell's terminals, the cell's estimated state-of-charge, or an amount of charge passing in or out of the cell during some interval. A battery-management system triggers full execution when the parameter falls below the threshold, or, if the parameter is the amount of charge passing, when it rises above the threshold.Type: GrantFiled: November 26, 2015Date of Patent: August 27, 2019Assignee: Renault S.A.S.Inventors: Vincent Heiries, Sylvain Leirens

Patent number: 10267861Abstract: An automatic estimation procedure for estimating a battery's state-of-charge includes predicting the state-of-charge using a state model that includes a state-transition matrix. An observation model then uses an observability matrix in connection with predicting a measured value of a parameter. State noise, the covariance of which is characterized by a state-noise covariance matrix contaminates this prediction. Similarly, measurement noise, the covariance of which is characterized by a measurement covariance matrix, contaminates this prediction. The values of these covariance matrices are then adjusted during the estimation procedure.Type: GrantFiled: November 26, 2015Date of Patent: April 23, 2019Assignee: Renault S.A.S.Inventors: Vincent Heiries, Sylvain Leirens

Patent number: 10267863Abstract: Automatically determining state-of-charge of a battery with cells includes, for each cell, scheduling refreshment times for the cell as a function of the cell's priority level, at times that correspond to refreshment times for the first cell, fully executing an estimation algorithm for the first cell, for at least a second cell of the set of cells, and at times other than those that correspond to refreshment times for the second cell, partially executing the estimation algorithm for the cell thereby obtaining an estimate of the second cell's state-of-charge, and determining a state-of-charge of the battery from states-of-charge estimated for each of the cells of the battery. The estimation algorithm estimates a cell's state-of-charge at a particular time as a function of a measured voltage and a measured current, both of which are obtained at the particular time.Type: GrantFiled: November 26, 2015Date of Patent: April 23, 2019Assignee: RENAULT S.A.S.Inventors: Vincent Heiries, Sylvain Leirens
