<P>PROBLEM TO BE SOLVED: To provide a battery system capable of easily determining the looseness of connection of a battery pack or the occurrence of device failures. <P>SOLUTION: The battery system comprises: the battery pack in which electrode terminals and conductive members of a plurality of secondary batteries are connected and fixed by fixing members; a first voltage meter measuring an electric power load connected to the battery pack and voltage between the terminals of the plurality of the secondary batteries; a second voltage meter measuring the voltage of the battery pack; a current meter measuring a current flowing in the electric power load; a control device receiving voltage parameter values of the plurality of the terminals corresponding to the voltage between the terminals from the first voltage meter, a whole voltage parameter value from the second voltage meter, and a current parameter value from the current meter; and a memory portion storing a contact resisting value of the battery back, an error value of the control device, and a threshold value of the current. The control device determines the looseness of connection when the current parameter value is more than the threshold value, and determines the occurrence of device failures when the current parameter value is less than the threshold value. <P>COPYRIGHT: (C)2012,JPO&INPIT |
