There is no visualization around electricity as a fuel type. So the visualization of charge was to simplify. Was to say, let's convert plug types into simple colors and power levels into simple numbers. And then we can tailor the charging map based on the vehicle so you know which stations work for them based on power. If it's below number six, it'll take longer. If it’s at number six, that's my best fill up if I need to fill up in charge.
