BATTERY CHARGING BASED ON COST AND LIFE
First Claim
1. A system, comprising:
- a battery;
an electric vehicle, the battery coupled to the electric vehicle to propel the electric vehicle;
a charging circuit to charge the battery;
a charging cost circuit to estimate a charging cost rate and to turn on the charging circuit; and
a timer circuit to provide a time signal to the charging cost circuit,wherein the charging cost circuit is to turn on the charging circuit during a first time period in which the charging cost rate is below a first threshold until the battery reaches a first energy stored level, and to turn on the charging circuit during a second time period in which the charging cost rate is above the first threshold.

Abstract
One embodiment of the present subject matter includes a system that includes a battery, an electric vehicle, the battery coupled to the electric vehicle to propel the electric vehicle, and a charging circuit to charge the battery. The embodiment includes a charging cost circuit to estimate a charging cost rate and to turn on the charging circuit. The embodiment also includes a timer circuit to provide a time signal to the charging cost circuit. The embodiment is configured such that the charging cost circuit is to turn on the charging circuit during a first time period in which the charging cost rate is below a first threshold until the battery reaches a first energy stored level, and to turn on the charging circuit during a second time period in which the charging cost rate is above the first threshold.

18. Method, comprising:
-
storing a user selected driving range for an electric vehicle; determining a potential driving range based on a pattern of driving ranges achieved by charging a battery of the electric vehicle to a first percentage of capacity; determining whether a first amount of energy stored when the battery is charged to the first percentage of capacity is sufficient to achieve the user selected driving range based on the pattern of driving ranges achieved; charging the battery to the first percentage of capacity if the first amount energy stored is sufficient to power the electric vehicle through the selected driving range; and charging the battery to a second percentage of capacity, which is higher than the first percentage of capacity, if the first energy stored is not sufficient to power the electric vehicle through the user selected driving range. - View Dependent Claims (19, 20)
