When I drive from home in Los Angeles to Santa Cruz, I drive Interstate-5 up through the Grapevine to Hiway-46 west to US-101 in Paso Robles to a DCFC. This drive is 196 miles, but leaving Los Angeles I go uphill into the Los Angeles National Forest and burn more KWs than I would on a flat surface.
I seek to gain as much of these back as I can to make a comfortable drive to Paso Robles, especially with the air conditioning on in the hot Central Valley of California.
So going down the 5 miles of the 6% steep downhill grade of the Grapevine, I get in the rightmost "Truck" lane and follow one of these trucks.
Their speed limit is 35 MPH at this point, but many will go 40 MPH, even passing in the next lane those going 35!
I am not trying to "draft" these trucks; I am just trying to safely drive at the slowest speed possible for use of cruise control in "L" mode to maximize regeneration during these 5 miles.
I typically regenerate 1.5 KW at 45 MPH and 2.0 KW at 35 MPH.
So, doing the math at an average of 238 miles per 60 KW of full battery; recovering 2.0 KW will not only cause me to not use any energy during the 5 miles downhill of the Grapevine, but get me another 8 miles towards my trip to Paso Robles; for at least an extra 13 miles.
Not only can I drive more comfortably, but if there is a problem at the single CCS DCFC in Paso Robles, I can then drive the additional 30 miles to San Luis Obispo to use the DCFC there.
But of course, regeneration over the period of 200 miles, gives me much more than that!
