Advancing plug-in hybrid vehicles is one of the keys to a cleaner environment and a better future.

But, it’s not enough.

We also have to keep improving how those vehicles are charged.

That’s why Toyota is partnering with Duke Energy and Energy Systems Network (ESN) on a project that promises to make charging a simpler, smarter process for everyone.

The project will be a real-world test of vehicles, charging stations, and a power grid designed to interface with each other, and with the driver, using integrated communications systems.

The goals: 1. To help make charging a simpler and more transparent process 2. To develop technologies that allow drivers to create smarter, more economical charging strategies 3. To make the most out of every precious watt-hour

During the year-long project, Duke Energy customers in the Indianapolis area will drive five Prius Plug-in Hybrid vehicles. Each customer will be provided with a Smart-Charger which consists of a home charging station, a gateway communication system, and a mobile tablet loaded with a special software application.

When connected to a Smart-Charger, the vehicle communicates important DR information to determine if alternate charge time and power levels help the driver take advantage of a lower charge cost. In addition, the vehicle communicates important information to the cloud based “Toyota Smart Center” that informs the driver when battery charging should take place and how quickly.

The software allows the customers to manage every part of the process of vehicle charging providing valuable information that helps us move one more crucial step closer to the cleaner, better world we envision.
