Systems and methods for reducing the cost of vehicle charging based on route prediction
First Claim
1. A system for cost-effective charge planning for a battery of a vehicle comprising:
- a battery having a state of charge (SOC) corresponding to a current amount of electrical energy stored by the battery;
an internal electric vehicle charger coupled to the battery and configured to receive electrical energy from a charging station and transfer the electrical energy to the battery to increase the SOC of the battery; and
an electronic control unit (ECU) coupled to the internal electric vehicle charger and configured to;
predict a route set including a first destination and a second destination and an amount of time spent at each,determine a confidence value corresponding to a certainty that the predicted route set corresponds to an actual route set that will be driven,determine charge planning data including an amount of electrical energy required to reach the first destination from a current location, an amount of electrical energy required to reach the second destination from the first destination, a cost of electrical energy at the first destination and a cost of electrical energy at the second destination, anddetermine how much to charge the battery at the first destination and at the second destination based on the predicted route set, the confidence value and the determined charge planning data.

Abstract
A system for cost-effective charge planning for a battery of a vehicle includes a battery having a SOC corresponding to an amount of energy stored by the battery. The system also includes an internal electric vehicle charger capable of receiving energy from a charging station and transferring the energy to the battery to increase the SOC. The system includes an electronic control unit (ECU) that can predict a route set including a first destination and a second destination and an amount of time spent at each. The ECU can determine charge planning data including an amount of energy required to reach the first and second destinations and a cost of energy at the first and second destinations. The ECU can determine how much to charge the battery at the first destination and at the second destination based on the predicted route set and the determined charge planning data.
