  In the above-mentioned prior art, when the voltage of the battery becomes lower than the set value, the user and the dealer are notified. However, the user and the dealer may not be able to respond immediately even if there is a notification. The problem is that the battery is already overdischarged and the engine can not be started.

  The present invention predicts when the battery will be overdischarged in a farm work vehicle equipped with a battery, and notifies the manager with a sufficient handling time to start up the engine of the farm work vehicle even after a while. to enable.

  The above-mentioned conventional problems are solved by the following technical means.

  According to the first aspect of the present invention, in the agricultural vehicle equipped with the battery 35 for starting the engine E, the discharge prediction means 45 of the battery 35 is provided, and the discharge prediction means 45 is started with the stop of the engine E A controller 40 is provided to notify the manager of the agricultural work vehicle of the overdischarge predicted time VWT predicted at 45 to the manager of the agricultural work vehicle by communication means.

  According to the second aspect of the present invention, the discharge prediction means 45 of the battery energizes the battery 35 every predetermined time with the timer 38, measures the voltage several times, and predicts the overdischarge prediction time VWT using the discharge prediction graph 41. It is set as the agricultural-working vehicle of Claim 1 characterized by the above-mentioned.

  According to the invention of claim 3, when the abnormal voltage is detected by the voltage measurement of the discharge prediction means 45, the controller 40 notifies the administrator of the agricultural vehicle as a circuit abnormality through the communication means as the circuit abnormality. I will assume a car.

  According to the invention of claim 1, the controller 40 of the agricultural vehicle predicts the overdischarge prediction time VWT using the discharge prediction means 45 along with the stop of the engine E, and performs the agriculture work with the predicted overdischarge prediction time VWT as the communication means. Since the manager of the car is notified, the manager can cope with it before the battery 35 is overdischarged even if he / she is away from the agricultural work vehicle, and the engine E will not start when trying to use the agricultural work vehicle. It can be prevented.

  In the invention of claim 2, in addition to the effect of claim 1, since the controller 40 can predict the overdischarge prediction time VWT by measuring the voltage of the battery 35 several times, the controller 40 is extended for overdischarge prediction. There is no need to drive and power consumption can be saved.

  According to the invention of claim 3, in addition to the effect of claim 1, the administrator of the agricultural work vehicle immediately recognizes the circuit abnormality of the discharge prediction means 45, and the repair can be performed quickly.
