RechargeIT.org: A Google.org Project

was launched in 2007 as an effort Google.org to demonstrate plug-in vehicle (EV) technology and its adoption. With several new now available in the marketplace, we’ve the RechargeIT initiative. In fact, updated our EV infrastructure to include than 30 of the newest plug-in as part of our employee car sharing Gfleet. We’ve started the Chevrolet Volt and Nissan and we’ll be adding new models as become available.

We’ve been busy creating the corporate EV charging infrastructure in the with over 200 chargers in place, with the goal of 5% of our parking spaces at our Mountain headquarters.


When we launched RechargeIT in there were no commercially plug-in hybrid EV’s in the market. So we developed a demonstration at our headquarters in Mountain View and Gfleet to make the cars to Googlers. We collected data the fleet and made it publicly and also conducted a controlled Experiment to assess the performance of vehicles.

Our plug-ins achieved 93+ MPG, and you can view historical data our fleet.

The RechargeIT Demonstration

Back in 2007, with no available vehicles to test, we had Toyota Prius’ retrofitted to them plug-in hybrid The vehicles used the Hymotion/A123 plug-in hybrid kit. All of cars were outfitted data recording devices tracked technical and environmental use patterns and charging history.

We both electricity and gasoline data to calculate the total use for each vehicle to get “real performance data. In order to this data to other under similar conditions, we four existing conventional with the same data devices. With this we were able to measure realistic MPG efficiency of plug-ins conventional hybrid vehicles.

The system to collect data our fleet consisted of an embedded running Linux, a wireless card, a GPS and an AC power monitoring to monitor charge power. The computer was connected to the vehicle’s (a data bus present in all new vehicles), and relevant data such as distance driven, fuel and the vehicle’s high voltage parameters. Information from the hybrid battery, such as current, charge state and temperature, was also accessed and for data analysis.

During charging, the system and recorded the AC charge power. The manager used GPS to track the location. In addition to the data on board, we used a fleet card that accurately the amount of fuel used by car which was then uploaded to our and used for the miles-per-gallon calculation.

all the data was uploaded to our servers, any calculations were done as calculating CO2), and the data was and made available publicly. was available at the fleet level, car level and charging event/trip

The driving experiment

We noticed employees primarily used the fleet for short trips to our headquarters, so the data wasn’t representative of typical U.S. patterns. While the data significant MPG improvements over our hybrid cars, we wondered the data would look if the vehicles were used for typical trips. We were curious to know how our plug-in would compare to other and non-hybrid vehicles that are found in the US fleet.

Hence, the RechargeIT Driving was born.
