Another application to add to the mental list – must be a huge bank to absorb all those Joules
…pauses to search….
17.9kWh according to this paper (https://core.ac.uk/download/pdf/55049866.pdf), which glanced through and (I might have misunderstood) seems to equate to 29tonnes of capacitors

Thanks Benjamin.
That made me try a little harder, and this paper (https://www.sciencedirect.com/science/article/pii/S2352152X2031940X, available in full) has this list of fuel cell + supercapacitor cars:
Honda FCX, Honda FCX Clarity, Honda Clarity Fuel Cell, Toyota FCHV-adv, Toyota Mirai and Hyundai NEXO.
So maybe it is fair to say that, so far, no mainstream electric cars have supercapacitors?

Morning Mike
MT3608, I have not seen that before – 2A boosting from such a little chip.
Mine used one of those little Zetex (now Diodes) boost converters (maybe a ZXSC310) which drained the capacitor right down to 800mV – what a neat chip, if unregulated.

I used them to shut down a Pi CM4 without corrupting memory. With a MT3608 boost convertor you can just drag enough energy out of a pair of them.

If the motor can handle it. That’s why auto start at stop lights is a bad idea. Better to idle than replace the starter every few years. Like I say, planned obsolescence or planned failure is fraud.

Thanks Mike
It is nice to hear that they are being designed in.
I made a bike light years ago with one – it is still working 🙂

The Hong Kong Metro and some other Chinese lines use supercapacitors to store all the braking energy going into a station, then accelerating away again.

The article I saw it in originally:
https://www.carmagazine.co.uk/car-news/tech/what-is-supercapacitor-battery-ev-and-hybrid/
I think this paper mentions it too but I can’t access it:
https://www.sciencedirect.com/science/article/abs/pii/S0313592618301371

Found it – Lamborghini Sian indeed – claiming that it is the first – and it does not appear to have a traction battery, just supercapacitors for brief 25kW boost, according to WhichCar here: https://www.whichcar.com.au/advice/lamborghini-sian-supercapacitor-explained

Thanks Bejamin

BTW, Struggling to find a Toyota FCHV supercapacitor reference – any ideas?

Thanks Benjamin
I stand corrected, and will take a look at these vehicles.
