Re: Would keeping the Overdrive help range?

Interesting and thank you!

Keeping the gearbox is mostly to make it easier to get through the TÜV. The less I change the less I have to explain.

I have an aluminum bell-housing and flywheel that bring down the weight by almost 20 KG. The gearbox itself only weighs about 15 KG (I know because I ...

Would keeping the Overdrive help range?

HI All,
I haven't posted much about my project because it is still in bits and pieces all across southwestern Germany but on the weekend I took my differential to a specialist to have it refurbished and put into an aluminum case (to save weight).

The car is a '72 Triumph Spitfire. Because of the ...

Re: 20kW DC charger from china

I don't know the cell voltage but I think we are looking at only 20-22KW total.
My concern is not speed but simply if I cake a trip not being able to find a Type 2 charger close to my route.
Almost are are CCS only...

Very interesting.. now if I could find something to go the other way as my conversion will likely be AC only (sub 200 volt). :-)

Re: Please don't stone me ;-) CCS to Type 2 AC Adapter/Converter?

Just to let people know I have not stopped researching this topic. :-D

Someone claimed there was a Tesla model a few years back that had AC charging only and that it had an onboard DC to AC charger converter that would allow DC charging without adapters... As with many claims on the internet I have ...

I am interested in them because:

-safety shutdown
But what about an EV converted classic car...?

Warning: Slightly off topic

The results look really nice and I don't want to be that guy , but be careful when zinc plating bolts (or parts in general). They can lose a lot of their original strength due to hydrogen embrittlement.

*snip*
Regarding heating, there is some good work being done on HV coolant heaters. That way you can keep the spitfire heater core.

Out of interest what battery, motor and charger set up do you have? You say you kept the flywheel and clutch as you are using the getriebe still. Most people still ...

Why is this bad?
Is it like marathon and sprinting?
You want marathon (slow and constant) for langevity as opposed to sprinting at high speed for short periods?

The battery sounds interesting!

My other concern is where to keep the fuel. The German TÜV likely has very strong ...

Hello, I have not yet fully understood your configuration. You say you have a flywheel? Is it a hybrid or a combustion engine? Does the 12V battery have to start an engine? There are ready-made lead-acid battery replacement solutions with their own 12V BMS. Nothing needs to be changed on the ...
