MyGreenVolt is an Android app designed for Volt/Ampera vehicle owners to display hidden information not shown on the car dashboard. Please note that an additional hardware requirement is necessary to run this app. You will need a Bluetooth or WiFi OBD2 adapter (ELM327) plugged into the diagnostic socket of the car (driver side).

This app is presented in an easy-to-read format and displays various data such as the instant power drawn from the main traction battery, the energy utilization breakdown for main traction, HVAC, Battery heater, and other components, and daily statistics such as energy usage, electric and gas miles. MyGreenVolt also provides information on the clear bar chart showing temperature of battery, transmission, AC/DC converter, and gas engine coolant. The app also shows the actual and raw state of charge of the battery, min, max, and average cell voltage, and individual cell voltage (In-App purchase). Moreover, it displays a graph of instant power of each of the electric motors, trip efficiency overlaid on maps, and a lot more data from various sensors. Both metric and Imperial units are supported.
