Abstract:
1. A charge control system comprising: vehicle-state detection means for detecting a running state of a vehicle; battery-state detection means for detecting a charge level of an in-vehicle battery: and power generation control means for predicting a discharge amount to be discharged by the battery under a discharge condition, setting a lower limit of the battery charge level on the basis of the battery charge level detected by the battery-state detection means such that the lower limit of the battery charge level is higher than a battery charge level at which the battery begins to degrade by the predicted discharge amount, and controlling a power generation amount of a vehicle generator according to the vehicle state detected by the vehicle-state detection means, wherein the discharge amount is predicted by subtracting a maximum power generation amount of the vehicle generator under the discharge condition from a load current value and then multiplying the resultant value by a predicted discharge time.
