Abstract
A battery system comprising a controller and a solid-state lithium secondary battery, wherein, the controller estimates an end part cathode potential Vefrom a voltage relaxation amount ΔV; the end part cathode potential Veis a local potential of an end part of the cathode; and the voltage relaxation amount ΔVis generated by diffusion of, into the non-facing part of the anode, lithium transferred to the facing part of the anode from the cathode of the solid-state lithium secondary battery is a charged state, and wherein the controller controls execution and inexecution of charging of the solid-state lithium secondary battery so that the end part cathode potential Veis equal to or less than a potential Vlimit at which a change in crystal structure of the cathode active material occurs.
