Low cost BMS

Well actually i believe i hurt one of my cells. When i charge at 40A it is the first one to reach 3,55V, but when i lower to 5A it falls down among other cells. Usually at this time i charge at 5A since other cells start to balance. In about 15min i have 42 cells leveled save one. This one - same o...

I've added my home in Mt Colah, Sydney. I have no reservations doing so as: 1) I've only put it in approximately 2) I've added my number for the person to call 3) I've advised that I don't answer "Private Number" callers and that you can turn off "Private Number" on a per-call basis by prefixing the...

Weber and Coulomb's MX-5

One thing i don't like about a lot of the off the shelf lithium BMS is why a lot of them need to take the cells to such a high voltage before balancing starts. Some don't even start balancing until 3.65V. There is a fixation with trying to get every last bit of capacity from the cells. I would much...

Public charging

I keep on having discussion about more infrastructure for EVs but in 3 months of ev ownership I've only publicly charged once. Is this just me ? Is it possible that you knowing that there is not a complete charging network is modifying your behaviour? I.E. You would do longer journeys if you knew t...

Did you go to a random mechanic when you got a pink slip*?
Was he a bit confused?

*For non-NSW folks, Pink Slip is the annual registration / roadworthiness check where they give the car a once-over, check that the car isn't falling to pieces.

It's a delicate balance with these engineers: they may be asking for something not legally necessary or in some way unreasonable, but I think it can sometimes be prudent to humour them rather than to insist on the letter of the law which may be on one's own side. A case of "You don't have to agree ...

Hi, I live at Mt Colah, about 2km off the F3 (oops, it's called the M1 now!), if you need a few amp-hours to make sure you get home from Sydney, you can plug in at my house. I have a 10A external power point (for my gas hot water), you'd just need a 5m extension lead. I'll send you my phone number i...

Looks therapeutic, like building a bicycle wheel... I watched the first video - it shows him putting 3 passes of 18 strands in each slot, he is going to end up with double that in each slot - 2 * 3 * 18 = 108 strands. Maybe work backwards using your scrap copper - see how many strands you can cram i...

My take on the Australian law is that there are 3 types of vehicles: a) motorcycles b) cars c) goods vehicles (trucks) Cars are the ones which have all the safety features NCAP testing, etc. It's pretty hard to get a new car design registered. Motorcycles are assumed to be dangerous, so it's not too...

You would have to agree that damage to a road is the product of a vehicle's weight and how often its used? It varies quite a lot in road construction, e.g. fully engineered road construction such as freeways and concrete roads cost a lot to build handle a lot of "kilogram kilometres" per maintainan...

Liquid cooling an industrial AC motor

I had a thought to run copper (ali for no galvanic action) pipes jammed between the fins and run water through them.
Another was to put the motor in tight (Ali?) duct and fan cool it by blowing air through.
