Woot, found some information on the Zero packs.
2012 bikes are supposedly 66 V nominal - applies to XU, S, DS (source
). 18 lithium NMC pouch cells, approx 3.7 V each. ZF3 is approx 40 Ah, ZF6 is approx 80 Ah, ZF9 is approx 120 Ah (source
That works out neatly to Zero's claims of 2.6 kwh nominal, 5.3 kwh nominal, 7.9 kwh nominal.
Brammo's BPM 44/70 module
is 44 V, 70 Ah nominal - very likely 12 3.7 V 70 Ah NMC pouch cells as well. Enertia Plus uses two modules (24 cells) for an 88 V 70 Ah pack, 6.2 kwh nominal
BrammoBrian also says the 2011 Empulse RR uses twice as many cells as the Enertia Plus. 48 3.7V 70 Ah pouches gives a 178 V 12.5 kWh pack - which is exactly the capacity that A&R reported a while ago
At one point the Empulse 10.0 was listed at 110 V
. Brammo's site now lists all 3 models
at 88.8 V. Of course, who knows if all 3 models will ship.
Likely still 24 total pouch cells, just larger capacities. 6.0 would use the Enertia Plus 70 Ah pouches. 8.0 would use pouches rated at 90-95 Ah. 10.0 would likely use pouches rated at 115-120 Ah.My question is this:
Can Brammo ship a bike with a 10 kwh pack (24 ~120Ah pouches), IET, 40+ kw motor, liquid cooling, J1772 / 3kw charger at the same price as Zero's 7.9 kwh pack (18 120Ah pouches), belt drive, 30 kw motor, 1kw charger?
If Brammo can.. then either their component prices are much better, their process is much less expensive, or Zero is making pretty huge margins on their bike. Either way, Zero will probably drop the prices on their bikes.
If Brammo can't.. then prices will go up or features will be cut. And there's probably going to be a communication blackout while Brammo figures out what it wants to do.
