    • Estimate of range left based on historic driving patterns and various sensor readings

H​

  • HEV​

    • Hybrid Electric Vehicle
    • A Vehicle that usually has a gasoline engine and an electric motor, but lacks plugin charging and relies mostly on regenerative braking the charge a small battery bank

"Range" needs a more complete definition.

"GOM" could start the "G"s

In V2G, change "co" to "to"--but isn't it really the ability of the power company to take power back from your EV when needed?
