Range and charging are still the sticking points, I see.
By now it should be crystal clear to Zero that rapid charging capability is absolutely key to increasing adoption. Cost too.
More range is always good, but they do manage this every year and I think they're doing the best they can with that.
I wonder if the real problem with fast charging is heat. I doubt that the 1C charge rate can be broken without active cooling of the cells. Especially after the cells are already warm from the highway.
I don't think heat generated while riding will be a huge issue.
Assuming Zero builds a 6 brick bike with ~150 miles highway range - detailed elsewhere - then highway discharge is about 0.5C. That's similar to 50-55 mph riding on a four brick bike .. not terribly taxing, and perhaps even sheds heat at most temperatures.
And charging a 174 Ah pack at 250A ("100" kW CCS / CHAdeMO) is 1.4C. That gives a 10-80% charge time of about 30 minutes for 100 miles of riding.
Compare to a Nissan LEAF, which uses forced-air cooling only. Highway riding is close to 1C discharge, and CHAdeMO quick charge (125A into 60 Ah pack) is close to 2C. INL determined that quick charging a Nissan LEAF daily had little detriment to pack capacity; question is, how well will Zero's chemistry perform?
