2p on battery design:
These pouch-style batteries are fundamentally different from the ones that are employed by Tesla and car EVs; they use the same basic design as the considerably less stable and safe batteries found in mobile phones. These batteries
do spontaneously catch fire and they
do explode. They are hugely more fragile than the cylinder style 18650 types found in cars.
Tesla are using massively reinforced battery packs with 18650-style cylinders and a less energy dense chemistry than the pouch batteries specifically because of safety concerns. They
will explode. Just because they have not exploded once does not mean that on balance they are safe. They are
not.
I believe Energica have opted to take the risk of using pouch batteries because the energy density is just that much higher than the 18650, and if there's one thing hurting electric motorcycle take up right now, it's range and weight. It's a stopgap until a safer chemistry comes along for the same energy density. But notice that Energica have wisely encased the lot in a lump of solid metal.
No-one in their right mind who knows anything about batteries would ride the Lightning with unprotected pouch batteries. There's more to it than "well, it didn't explode last time I rode it".
Consider all these factors:
1. What happens when you crash it? (Very high risk of extraordinarily fierce fire that
cannot be put out with conventional (red) extinguishers most people have to hand)
2. What happens when you crash it in the wet? (As well as the risk of fire, there is a severe risk of a
very high voltage short which poses extreme risk to the rider if they remain on the bike when it's crashing, or if they try to pick it up again, or to
anyone in the emergency services that attempts to pick it up - see MotoE insulated shepherds' crooks if you don't believe this)
3. What happens when one of the pouches begins to expand as it fills with hydrogen gas, as they frequently do in other applications with this design? (Hint: it involves hydrogen gas under high pressure, shorting, and what happens when you mix hydrogen gas, air, and electric sparks)
4. What happens when you're washing salty road grime off with a sponge?
5. What happens after a relatively minor spill which you forget about for a few days?
