Hypermiling in a Model 3

Post by Nagaman » Tue, 03 Dec 2019, 18:40

Being retired we do a lot of ‘pottering around’ @ 80-90 kph and just wondering if anyone has done a max range test of any sort, particularly in the SR+ ?.

In another forum "Lex" posted actual 350kM range in a SR+, two adults, 2 children with luggage at 90kph on a coastal drive. Of course, you should only 'Hypermile' when absolutely necessary (100% to 0%) and generally aim for 90% to 10% for battery health, contingencies (head winds, roadwork or other diversions) and stress free touring.

Thanks Chris, I’m more interested in the average WH/km rather than 100%-0% range.
One interesting (to me at least) example is a trip over the 6000 ft Mt Hotham with a relatively short, steep/slow windy climb and a faster, longer and straighter descent.
Is one direction better than the other for total range?.

In theory the steep climb - gentle descent should be better, since you are not wasting the power that went into gaining altitude on brakes/regen inefficiencies. Would be more interesting to hear from someone who has tried it though.
On the same theory on a bicycle I should put in max effort on the uphills and just coast down but I always do the opposite because it feels better.

Hi Guys - I can confirm that a steep climb at gentle speed....then a long gradual descent works best for Hypermilling. My example is Hartley to Penrith (compared to the reverse) - with a short steep climb at 60kph to Mt Victoria....then the long coast downhill to Penrith. A long downhill descent at the end of a trip is useful when planning a Hypermilling trip - such as reaching the fast chargers at Bathurst from Yetholme (25kms) with virtually no depletion on your predicted range.

So does one pedal driving regeneration cope with the steep bits or do you need the wasteful friction brakes as well ?.
