AI Thread Summary
The discussion focuses on selecting a battery for a hybrid motorcycle project, emphasizing the need for clear performance specifications such as acceleration, range, and carrying capacity. Participants suggest that the project should start with defining a realistic scope and conducting a feasibility study before diving into battery selection. Lithium Iron Phosphate batteries are recommended for their safety and fast charging capabilities, while alternatives like nickel metal hydride and lead-acid AGM batteries are also mentioned for cost considerations. The conversation highlights the importance of understanding the hybrid drive system's requirements as a priority over other design elements like tires. Ultimately, establishing clear project parameters is crucial for successful design and implementation.

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?
 
Engineering news on Phys.org
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.

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.

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?

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.

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.

A feasibility study is the next step.

this!
lol, I was trying to help him do this!

I realize you are enthusiastic, and are trying to apply what you have learned to help, but in this case we need to take it one step at a time.

The first step before any project, is scope and feasibility. This is done before all projects in the engineering world. It's basically the same as a literature review in Science.

The OP should begin scouring the interwebs and technical journals/magazines. For any information related to hybrid bikes. Futher to this, he needs to define the scope of his project. This involves him sitting down, and estimating what he is realistically going to be able to achieve with the time and resources available. It's better to a good job with a smaller scope, than a poor job by being overly ambitious.

If he can't satisfy the "hybrid portion" of his project, the tires won't matter.

I am sure any tire he might need is already being manufactured.

What is not easily found on the market is the subject of his original post.

Can nickel metal hydride battery be used...
 
  • #22
To keep your cost down consider a lead acid AGM battery. Compact and light. Takes a very high amp charge. Select one designed for high cranking amps.
