Don’t flip out, Tazinator. There’s a surprising number of people on both the old forum (not the old, old forum) and in the DRI/FreeSK8 Telegram chat talking about e-bikes, Onewheels and scooters as well as esk8s.
Considering we all face the same electronics hurdles and legislative challenges, it makes sense to be more agnostic about what people ride.
I myself plan to either build or buy an e-bike over the next six months or so.
As I stated, I have not issue about people asking for advice on whatever EV.
Hell if they ask for advice on anything I have some knowledge and can help I see no reason not too.
I am just sick of the current political correctness where you can’t call an apple an apple because the pear will feel left out.
Anyway. Carry on.
What would happen if I were to use my 100w USB c cable/wall charger combo to plug my puck? It’s made to run at 19v/5a for my phone but I don’t wanna feed that to the puck. Would the circuit on the puck prevent this?
It will work, but only on cables with type A on the other side.
Cables with type c on both sides (the ones with the fancy high voltage negotiation) would not work at all with that adapter (or type c transplanted into the puck I guess). They don’t just default to 5 volt for some reason.
Type c plug is great physically, but the data/power protocols are a shitshow
alright. Prepare the facepalms. Ive always had this gross concept error and never bothered to correct myself.
Assuming 12s4p 30Q with dual TB6380 190kv which is a pretty common set up…
What would be the general set up for each of these and why? (Let’s assume total. So add both vesc values)
Absolute max current
Even if we set motor amps to 80A, wouldn’t battery current set to 60A prevent motor amps from reaching 80A anyways? And what’s battery max vs battery current? To have stronger brakes at higher speeds, should I increase motor brake or regen?
Also what actually causes ESCs to fail? I’ve been blessed by the gods and never had a failure and I’ve probably worked on a dozen boards. Assuming we kept within rated operating limits, why do they send you flying? AS failure, direct fet failure, blown drv, thermal throttling? What in the hell is all this
Not really because of duty cycle.
Motor side will have lower voltage but higher amps. Battery side the voltage can’t change (besides voltage sag and drain over the discharge for sure) so in fact the set motor amps do limit the bat amps.
