摘要
The present invention is a lithium-ion secondary battery system having a lithium-ion secondary battery, potential measuring sections, a voltage applying section, an electric current measuring section, and a switching section. The lithium-ion secondary battery has a positive electrode reference electrode, a negative electrode reference electrode, a positive electrode, and a negative electrode; when the positive electrode reference electrode and the negative electrode reference electrode are connected with the switching section, an electric current when a voltage is applied between the positive electrode reference electrode and the negative electrode reference electrode with the voltage applying section is measured with the electric current measuring section; and when the positive electrode reference electrode and the positive electrode are connected and the negative electrode reference electrode and the negative electrode are connected with the switching section, the potentials of the positive electrode and the negative electrode are measured with the potential measuring sections.
