Hmm I get 60 mixed with the Empulse, I would think the 2021 SS9 could do 100 miles =/ The battery has like double the capacity.
With a battery, an KWH is only a KWH at the current draw where it is tested. So to get a realistic comparison in KWH of batteries you have to first know the current draw.
Here is an example, when we compare the 13.4 KWH Energica battery to the new 21.5 KWH battery:
By Energica's own specs:
The 13.4 KWH battery range spec is 124, 100, and 80 miles.
The 21.5 KWH battery range spec is 249, 143 and 112 miles.
But the 21.5 KWH battery has a spec of 60% more KWH than the 13.4 KWH battery.
However,
That is in percentage of range improvement as 100%, 43% & 40% increase with the 21.5 KWH battery. At what speed do we find that 60% increase in KWH?
I assume the 80/112 freeway miles is at ~65 MPH.
I assume at 80 MPH, both the 13.4 & 21.5 KWH battery could have around the exact same range.
At 100 MPH, perhaps the 13.4 KWH battery has a better range than the new 21.5 KWH battery.
That's why I would like to see a chart on each, like Tesla has. I know my Tesla Model 3 (LR, AWD) gets 420 miles of range at 38 MPH, 320 miles at 65 MPH. etc.
With the 21.5 KWH Energica battery, I expect the nominal KWH reduces a lot more with load than does 13.4 KWH battery.
The big advantage of the 21.5 KWH battery is at slower speeds, where the range doubles and has the same charge time per mile as the 13.4 KWH battery. As the speed increases, it looks like the difference becomes less and less between the new and old battery by Energia's own range specs and requires longer charge times to go the same distance.
If going fast enough, is it possible that the 13.4 KWH battery gives better range than the newer 21.5 KWH battery? I kinda assume such is possible, say at above 100 MPH.
The Energica 21.5 KWH battery also gives less range on a charge than does the 13.4 KWH battery when compared at freeway speeds, by their own specs.
When Zero batteries are compared, double the battery size in KWH and get exactly double the range at ANY speed. Double the charge rate/time and likewise get double.
Zero batteries are very linear and can be compared by KWH. Energica batteries are very non-linear by their own written specs.
It seems to me that Energica cheated a bit to get that 21.5 KWH rating, trying to say they get the best mileage of all electric bikes--which is probably true but ONLY at slower speeds. That is not how we normally ride an Energica. A 2018 Zero SR with power tank (18.0 KWH <150 miles combined riding>) gives better range than the 21.5 KWH Energicas at any reasonable speed (143 miles combined).
Now if they could get that 60% KWH increase at freeway speeds. they would really have something worth considering.
Bottom line is:
Do not get fooled by battery KWH specs!
