<p><P>PROBLEM TO BE SOLVED: To provide a suppliable current prediction device which enhances prediction precision of the value of a current suppliable through a battery. <P>SOLUTION: The suppliable current prediction device calculates the voltage/current characteristics of a battery 10 based on sampled voltage value and current value of the battery 10 connected to electric loads 41-44, and predicts the value of a current suppliable through the battery 10 based on the calculated voltage/current characteristics. The suppliable current prediction device comprises a reference table (20) storing the number of revolutions of an engine 61, and the maximum output current value of an onboard generator 51 corresponding to the temperature of the onboard generator 51 interlocked with the engine 61, a means (24) for acquiring the maximum output current value with reference to the reference table (20) based on the number of revolutions detected by a number-of-revolutions detector 62, and the temperature detected by a temperature detector 51, and a means 24 for predicting a suppliable current value based on the maximum output current value and the voltage/current characteristics thus acquired. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
