I hear a lot that the cost of batteries has plummeted. But is that true? If I look at the attached graph the AVERAGE cost of batteries went from around 600$/kwh in 2014 to around 400$/kwh in 2020. That is not exactly plummeting in my humble opinion. I must admit that I was also surprised to see that the drop in prices is much less than I expected.
Plus the battery also increased in kwh from 2014 to 2020 (well actually up to 2018 because 2018-2020 has seen the same battery size)
2014 : 11.4 kwh * 600 $ = 6.840 for the batteries alone
2015 : 12.0 kwh
2016 : 12.5 kwh
2017 : 13.0 kwh
2018 : 14.4 kwh
2019 : 14.4 kwh
2020 : 14.4 kwh * 4000 $ = 5.760 for the batteries
so the battery price for Zero has "only" gone down 1000 dollars in those years. So there is not much to be saved there.
And there is another thing,
Because the space on a motorcycle is so limited, Zero opted to use Pouch cells, which are very energy dense and space efficient in a battery pack compared to round batteries where you lose a lot of space between the batteries. But these pouch cells are more expensive because they are produced less. And Zero has chosen to use the pouch cells with the highest density each year (i.e. the top model of the battery supplier, hence high prices). Pouch cells are also not the main stream package of batteries so there is no real mass production of pouch cells compared to the for example the round laptop or Tesla cells. So pouch cells are relatively expensive.
Using round cells like tesla in a motorcycle would greatly increase the size and weight of the battery so that is a nogo terrain for Zero (again, in my humble opinion
)
Also I think that if they ware able to make a motorcycle like the SR/F for 10 or 15 thousand, they would absolutely do it.
And to disappoint a lot of people wanting it :
The unicorn of an electric motorcycle with a highway range of 300 km (i.e. 40 kWh battery!), charge time of 15 minutes (i.e. 160 kW!), weighs less than 200 kg, has a 0-60 of < 3 seconds AND costs 10.000-15.000 US$/GBP/Euro's does not exist (duh) and WILL not exist for many years! BUT that said, try a Zero, buy a Zero and enjoy the ride !
I know I did yesterday for 280 km riding 2 up through beautiful sceneries (we are fortunately still allowed to go outside, as long as we keep distance to other people), charged at only 1 stop for 50 minutes, which cost 3 euros and had an absolute blast the whole day.
