A battery system comprises one or more lithium ion secondary batteries, charge and discharge control means, and internal resistance detecting means. The charge and discharge control means comprises a plurality of mode control means including first mode control means and second mode control means, mode selecting means for selecting one mode control means to be used from the plurality of mode control means, wherein a discharge current by the second mode control means is made smaller on a predetermined discharge conditions and equal to or smaller on other discharge conditions than a discharge current by the first mode control means, and the mode selecting means is configured to select the second mode control means when the internal resistance detecting means detects or estimates that the internal resistance is relatively high, and to select the first mode control means when the internal resistance detecting means detects or estimates that the internal resistance is relatively low.
