Battery selection for the hybrid motorcyle

sherazi21st

hi all,
I'm designing a hybrid motorcycle and want to select a battery for that. Can anyone tell me what will be the input parameter for the selection of the battery the motorcycle?

what kind of performance do you want from the bike (acceleration, range, carrying capacity, etc)

I don't have any specific performance specs. This is final year project of BS. You can assume any specs. My project is to design a hybrid motorcycle with any specs.

""input parameter for the selection of the battery the motorcycle?""

capacity, weight, discharge rate

no specs?
then use a AA battery. cheap & readily available!
and it fits in with all the other requirements you have!

Would this hybrid be using an inverter or will it be DC?

ok, serious answer: you need more design specs- think about what you want your motorcycle to do!
I'm a member of an automotive design club (FSAE) at my school, and we had someone come in and talk to us about design. He said to pick our tires, and work around them- so once you have acceleration/handling specs figured out, you can pick tires that can handle them, and design your engine/frame/etc. around that.
From that point, you can start thinking about more in-depth features, such as what battery you need

I'm pretty sure that the "hybrid" part is the main focus.

jehan60188

why do you say that?
the "hybrid part" (whatever that may mean) isn't what's going to be in contact with the road. A battery can't prevent a skid.

"Engineers, in the fulfillment of their professional duties, shall hold paramount the safety, health, and welfare of the public."

or did you forget your engineering ethics?

HowlerMonkey

He's asking about hybrid batteries and you discuss tires?

Maybe I can author a thread about PRTs on a 3350 radial and you can suggest I need to get the landing gear doors sorted out before I pick my engine.

OP was tasked with developing a motorcycle that is hybrid. He has no other specs. Designing around tires is prudent, because they are in contact with the road, and are directly responsible for acceleration/handling etc.

HowlerMonkey

He asked about the hybrid battery.

And in subsequent posts, OP made it clear that his project wasn't to select a battery, but rather to "design a hybrid motorcycle with any specs."

Go with Lithium Iron Phosphate batteries, as they're the only ones that won't explode from impacts amongst the secondary battery types with the best capacities. They also retain their capacity a lot longer than other lithium batteries and charge 10 times faster. This enables you to take a charger with you to re-charge in 10-20 minutes if needed for extremely long trips, compared to the hour+ charge of other lithium types.

It is you who guided the topic toward tires from his original post.

Scroll up.

I guided the topic towards an engineering solution. "Teach a man to fish..."
That being said, your shortsightedness in engineering is humorous and frightening. You lack the capacity to think beyond anything besides a bandage solution, and I hope for the sake of humanity you aren't on any important projects.
You can continue trolling in this topic, howler, but I've got better things to do.
Live long, and prosper.

You've kind of missed the point. The remit is to design a hybrid drive system for a bike, that's the focus, not the bike itself. The bike, beyond some very basic parameters, is irrelevant.


The first thing the OP should do is define a realistic scope for his project, along with a feasibility study.
