According to my car, it lets me drive 4.2 miles at highway speeds.
- qoobaa 10y agoInteresting, is it Tesla? Which model is it?
- freerobby 10y agoAs a reference point, a Tesla 85D uses 290 watt-hours to go one EPA rated mile. So 1 kWh takes you 3.448 miles.
- chrisseaton 10y ago> one EPA rated mile Are EPA miles not the same as normal miles?
- detaro 10y agoWhat's a "normal mile" regarding energy consumption? There is a series of standardized driving profiles that is averaged to get a comparable, somewhat realistic value.
- spydum 10y agojust guessing, it's a standardized way to declare the driven distence, given all the variables.. such as: up hill, down hill, low/high rolling resistance surface?
- walrus01 10y agoI think the poster means the EPA test cycle for miles, they have a pre-defined "cycle" of acceleration, braking, coasting etc for Highway ratings and City driving.
- ctdonath 10y agoI had a Leaf; the typical cruising power consumption was 4 miles per kWh. Battery was 26kWh.
- revelation 10y agoA kWh gets me easily >30km on my bike (250W for 1h if you assume average 25% efficiency)
- adrianN 10y agoBut you don't ride at highway speeds ;)
- whamlastxmas 10y agoBike also doesn't weigh 2500 pounds
- titzer 10y agoDrivetrains on bikes can be > 98% efficient, so I assume you mean the human power output efficiency. But 250W applied directly to the crank via an electric motor should get you a good 40km/h for 4 hours! :)
- 205guy 10y agoIn a Nissan Leaf, you can get around 5 miles per KWh average. You can plug in the 1.1 kWh charger and realize you will get 5 miles per hour. If you use a bigger 6.6 kWh charger, it's 30 miles per hour. Better yet, you can fiddle with the dash controls and get a power meter: acceleration takes 30-60 kW, but regeneration can make up to 30kw. Like the OP says, this kind of thinking really changes your perspective.
