Abstract: A power supply system includes a lead battery supplying power to the electric load of the vehicle, a battery sensor unit acquiring a value related to a state of the lead battery, and a battery deterioration determination device determining deterioration of the lead battery based on the value acquired by the battery sensor unit. The battery sensor unit acquires a value of a charge amount of the lead battery, a value of a discharge amount of the lead battery, and a value of a discharge depth of the lead battery. An ECU calculates a value of an effective charge/discharge amount of the lead battery based on a charge amount acquisition value, a discharge amount acquisition value and a discharge depth acquisition value acquired by the battery sensor unit and determines deterioration resulting from softening of a positive electrode active material based on the value of the effective charge/discharge amount.

First programs for each job step of each job for executing the operation in a system environment of a first computer, and second programs obtained by changing each first program in accordance with a system environment of a second computer to which the operation has been migrated, are stored in a storage apparatus. The second computer executes each job step of each job based on the second program; and if the second computer fails to execute a job step of any one of the jobs, the second computer issues a substitution instruction to the server apparatus to substitute for the second computer to execute the job step and the server apparatus executes the job step based on the first program.
