Yeah looks suspicious for sure. Who knows what's been hacked up on that car.
First we'd probably need to determine if that's a Tesla-style car :mrgreen:

Re: Thyristor-based load switching

I think one of the reasons contactors get used is for safety's sake because they provide galvanic isolation That's not really a fact. More often than not contactors have the same coil voltage as the main voltage they're switching, so they're activated by directly applying pack voltage. There is not...

Re: Thyristor-based load switching

Like FETs, a common failure mode of Thyristors (SCRs) is shorting anode to cathode. So...you would be unable to use the switch to disconnect the load, and if the purpose was a safety disconnect, it would be unsafe. And contactor can have the contacts welded and being unable to disconnect :) Solid-s...

Then it was toxic chemicals. Then it was child labor. Now it's CO2. Tomorrow we will find out that EV batteries cause illegal immigration, terrorism and bad breath.

Re: Thyristor-based load switching

This is the one I am mostly wondering about : http://www.learnabout-electronics.org/Semiconductors/images/SCR-DC-motor-cct.gif How much current would that stop switch need to handle ? Seems like this would be easily implementable with a... contactor, but then it sort of defeats the purpose other tha...

Re: Wind and Solar vs Coal, Gasoline, Nuclear

Wife and I don't have kids. Take as many electric cars, solar panels, permaculture gardens and vegan diets as you want, but our decision will still have more impact. Your decision also carries the highest cost of opportunity. What if your kids grow up in your image and come up with the greatest bre...

Thyristor-based load switching

Has anyone tried to use thyristors to replace contactors ? I have some beefy ones capable of 150A, but not sure what the best approach would be to implement the "off" circuitry. This looks safe, but requires two thyristors : https://circuitdigest.com/sites/default/files/inlineimages/u1/Class-D-Thyri...

Re: No future for charging networks ?

At the moment EV cars have a rang of what, 300 to 500 km ? So enough for normal commuting but not for a big road trip. On par with gas / diesel vehicles that are used for long road trips all the time. But you can see it coming that battery capacity per weights and cost will come to the point that a...

OK. So when your doctor tells you you have a heart defect, and need immediate surgery if you want to survive, he is only giving you an "estimate" - and you will ignore him since it's bad science.

Besides deflections, can you answer the question I posted earlier? What is the energy trapping potential increase given "insignificant" increase in CO2 levels ? Purely based on physics that is.

Re: Wind and Solar vs Coal, Gasoline, Nuclear

So a CO2 goes from 300 ppm to 400 ppm. That is, every cubic metre of atmosphere now has 1.5 times as many CO2 molecules as it used to have. And you're telling me that is the same as a 0.015% increase... You have a very unique way of trolling - by demonstrating a lack of understanding of mathematics...

the real information waits for you on the internet to finally get clued up.

All when the best PhD scientists in climatology say there's nothing going on, climate change is all modelling that has no resemblance to what's really happening on the planet.

Re: Wind and Solar vs Coal, Gasoline, Nuclear

Plastics are polymers typically formed through application of heat and pressure. Heating them again without presence of oxygen and at reduced pressure will probably result in breakages of the chains and reduction of them to monomers without any combustion.
