Agents don’t need sound effects. But I do. I made a tiny Python “music alert” for when my agents finish running: original dual-track chiptune jingles with a properly raunchy bass line. success → end-game credits vibe failure → nervous twitc

My biggest frustration as an academic was reproducibility of papers I was reading. The pdf is such a useless medium for information transfer and the academic publishing industry is a complete racket where all the value is generated by the a

Also good point on degradation. Physics based modelling is invaluable for debugging this. PyBaMM does have quite a bit on degradation yes. Here's a good notebook to start with https://docs.pybamm.org/en/stable&#x2F

Good question. I would say anyone developing new materials in a lab would benefit from the kind of physics-based models we have in PyBaMM. Organizations is a pretty broad term but I assume you mean companies in which case probably the numbe

Yeah I thought so but like most legends contains a kernel of truth and is certainly worth remembering for the lesson. Reminds me of the midwit meme https://www.ycombinator.com/library/IW-dalton-michael-elon-m...

PyBaMM predates ChatGPT. But we're emulating cyclers which are fairly basic tbh. I'm exploring ways of using LLMs to improve the experience. ie Cycle my NMC-Gr 18650 with a CCCV at 1C with an RPT cycle of CCCV and GITT at C/1

For anyone interested in the performance requirements for electric flight, alluded to but not explored in the article. This is a great open-access paper about it https://pubs.acs.org/doi/full/10.1021/acsenergy

Hahaha. No marshmallow instructions for us yet but some people are using PyBaMM to model thermal runaway. We don't use an LLM but I guess could in order to catch more edge cases. There is an experiment class and a step class. Each step

Related topic there is this example combining PyBaMM and pints for sensitivity analysis. Which should definitely be done first before delving straight into a DOE https://github.com/pints-team/electrochem_pde_model

I used Hall effect sensors for a project and found they needed a fair bit of calibration. Shunt resistors also did the job with fewer problems but this was a 16p2s module.

Hopefully. The thing that makes most sense is two-way charge points but for whatever reason these aren't that common

Nice! I love the simple approach like the story which I'm not sure if it's true or not that NASA spent $$$ developing an ink pen that would work in zero-g and the Russians used a pencil.

Yes completely agree. This is one of the things that PyBaMM doesn't do for you out of the box. I could have extended the article in many ways to cover all the optimizations you could do both with the physical battery or the model. Than

Fantastic! I will now enter the rabbit hole

Yeah thanks for the extra insight. On the modular modelling system bit, this is something we're not particularly good at telling people or highlighting. You can solve any PDE you want with PyBaMM but a lot of the high level battery mod

Great concept. Now I want an e-bike even more. Yeah I'd be happy to chat. My contact details are in the readme.

Yes this should be possible. I think the main constraint would be keeping the cell chemistry the same so that OCP is similar. I've been playing with a pack model of cells with mixed capacity using another open-source tool in our pybamm

Thanks for the advice, I have followed it

Haha - yes. all you need is a readme and a python package that can generate gifs. We put this in PyBaMM for our BattBot project https://github.com/pybamm-team/BattBot which was done by this awesome GSOC student who now

By the way if I was to edit the title I would put "design" at the end but I can't find how to do this? Not a very regular poster I have to admit

That's a fair point. I guess I used it a bit too freely but I have the habit of introducing programming terms into everyday life. It's trying to understand why something is suboptimal

Good to know, do you develop battery powered hardware?

That's cool. I'd love to be able to do that but my hacking skills are somewhat confined to the digital domain. What's going to be really interesting in the next few years is the number of batteries coming out of cars which co

Yes, parameterisation is incredibly important. The classic recent example from academia that heavily features in PyBaMM is Chen2020 which is a very thorough case study of collecting data. https://iopscience.iop.org/article&#

I'm sorry that you found it terse. I intended this as a brief intro and would encourage people who found it a little bit interesting or relevant to their problems to either read the more extensive examples on PyBaMM. If of interest, Si
