Once sales and marketing get involved all logic gets thrown out the window
Engineer: “We’ve designed this system to run at 18V using X model batteries available at such and such source.”
Project Manager: “How are the safety aspects?”
Engineer: “We’re using components that allow the system to safely handle up to 20Vs”
Hey, can’t you guys debate something without it getting personal? That kind of silliness is the last bastion of the desperate and completely negates the legitimacy of anything you have to say…sheesh.
The tech stuff you guys bring up is worth reading. Your personal crap wastes my time.
If any cell (or electrolyte) factory has enough vapor escaping that the atmosphere is explosive then they have some verrrry severe safety and/or QC issues to address!
This was at a project site in Denmark that had an experimental hydrogen electric generator- hence the spicy air warnings. Not my every day, was just on-site to survey & spec the project.
Yep but it pushes the cables downwards so the hole in the box is up high, while the cables exit low. Water would need to defy gravity to get up and in. Not impossible, but unlikely.
Yep. Both of these parts use an EVA foam gasket, and the loop key part in the lid is fully glued up on the inside to (hopefully) prevent any water ingress
One thing that I have really grown to dislike is panel mounting connectors like you have shown there. For me, the fuckers just always work loose. This can be mitigated with extra ‘stuff’ to hold them together, but then shit gets bulky.
When they’re out on the wire, they seem to just hold together like they’re supposed to
I can share the files, thats not a problem remembering to do so in the morning may prove to be a much more difficult task
Using this phrase demonstrates a lack of understanding of what both of these words mean.
A rating is an operating limit of a device measured in characteristics such as voltage.
Nominal means “in name” or “existing as something in name only; not actual or real”.
“36V” is a fucking name. A name just like George is a name. It has little to with the voltage the equipment will be operating at.
“36V nominal” means that three-six-V is a name — it’s not a number nor is it a measured voltage. They could have just as easily named it Demetrius or Gary36.
Likewise, something named “36V” cannot be rated at 36V or it simply won’t work if it’s actually operating at 42 volts.
This is ebike jive in a nutshell. I suggest using actual voltages, the kg⋅m2⋅s−3⋅A−1 kind of voltage, and not names, when engineering electric vehicles.
