CHARGE/DISCHARGE ASSIST DEVICE
First Claim
1. A charge/discharge assist device comprising control means for assisting charge or discharge of a battery installed in a piece of equipment, the charge/discharge assist device being whereinthe control meansacquires information concerning past consumption of power of the battery in the equipment,creates a rule curve representing a relation between time and an estimated necessary electric energy at each point in time which must be reserved before that time on the basis of the acquired information concerning the past consumption of power of the battery in the equipment,estimates and determines a charge start time at which charge of the battery is to be started or a discharge stop time at which discharge of the battery is to be stopped, by use of the created rule curve, andoutputs the estimated and determined charge start time or discharge stop time.

Abstract
An electronic control unit of a charge/discharge assist device has a data input section, a departure/arrival time prediction map generation section, a travel distance prediction map generation section, a rule curve creation section, and a data output section. The input section inputs departure time information, arrival time information, and travel distance information. The prediction map generation section creates a map for providing a predicted departure time in future and a map for providing a predicted arrival time in future. The prediction map generation section creates a departure-time-zone-specific predicted travel distance map for predicting the longest travel distance in each departure time zone. On the basis of the predicted travel distance map, the creation section determines an electric energy required in each time zone and creates a rule curve. The output section creates a charge plan or a discharge plan by using the rule curve and outputs the plan.
