Abstract
A battery system (SV) comprises a lithium ion secondary battery (), charge and discharge control means (S, S-S), and internal resistance detecting means (M). The charge and discharge control means comprises: mode control means including increasing mode control means (S) for increasing the internal resistance of the lithium ion secondary battery and decreasing mode control means (S) for decreasing the internal resistance; and mode selecting means (S, S) for selecting the decreasing mode control means (S) or the increasing mode control means (S) when a level of the internal resistance is estimated by the internal resistance detecting means.
