Abstract
Official abstract text for this publication.
A battery control device is provided that uses a discharge to adjust the capacitance of cells that form a bipolar battery and calculates the voltage increase value of the remaining cells that do not discharge to adjust capacitance if one or more cells, among all of the cells that form the bipolar battery, are discharged to adjust capacitance in a battery control device that controls voltage dispersion or volume dispersion between cells that form the bipolar battery; and setting the general discharge value when there is a discharge to adjust capacitance on the basis of the result of the voltage increase value calculation.
First claim
Opening claim text (preview).
The invention claimed is: 1. A bipolar battery control device comprising: a controller programmed to adjust one of a voltage dispersion and a capacitance dispersion of one or more of a plurality of alternately laminated cells of a bipolar battery by discharging the bipolar battery such that some of the cells of the bipolar battery are discharged and some of the cells are not discharged, in which each of the cells includes a positive pole active material layer formed on one face and a negative pole active material layer formed on the other face, with a current collector formed of an electroconductive thin film between adjacent ones of the cells, the controller being programmed to perform a voltage increase value calculation that calculates a voltage increase value of the cells of the bipolar battery that were not discharged after a discharge of the bipolar battery to adjust the one of the voltage dispersion and the capacitance dispersion carried out on one or more of the cells that form the bipolar battery, the controller being programmed to determine a general discharge current value for discharging to adjust the capacitance based on a result of the voltage increase value calculation. 2. The bipolar battery control device as described in claim 1 , wherein the controller is further programmed to determine a number of cells to be discharged to adjust the capacitance from among all of the cells that form the bipolar battery based on the result of the voltage increase value calculation. 3. The bipolar battery control device as described in claim 2 , wherein the controller is further programmed to determine a discharge current value of the cells to be discharged to adjust the capacitance based on the result of the voltage increase value calculation. 4. The bipolar battery control device as described in claim 1 , wherein the controller is further programmed to determine a discharge current value of the cells to be discharged to adjust the capacitance based on the result of the voltage increase value calculation.
