Re: My First Post - Does anyone know anything about the Solectria DW Electric Car?

1 - With the Batteries, If the Motor is a 240v AC motor, Does that mean if I buy 12v Batteries x20 will = 240V or am I missing something? To make a Sinewave From DC the DC needs to be 1.414 SQRT(2) times higher than the AC. So as stated above you need 240V AC x 1.414 = 340V DC 2 - If I use 24v Truc...

Really you can convert anything.
I'd expect there to be something else in Oz that would be better value.

20 x Leaf Cells

So I made the executive decision that I have too many batteries for my Handi project. If I drop out 20 cells I only need one battery box, less BMS, interconnects etc.. Simplifies the whole thing really for me. Originally I was just going to fill up the whole car. So I have 20 Leaf cells (gen1) up fo...

Yes with parallel fets you end up with cascade failure.
With such a light load it should be ok for a while.

Re: Is anyone using an arc welder with an offgrid system

Mmmm I've seen plenty of popped fets over the years. What is unusual is the broken left leg. If this is the gate then that is floating. Floating gates are bad. They have a tendency to turn on when you don't want to. I'd say the leg was stressed from bending to fit into the PCB. The heatsink moved du...

Re: Rolf's 1959 Puch SR150 scooter

The peak is 11kW for 30secs. Accounting for some looses thats ~260A into the controller. The 150A LTO BMS cuts out at 200A. The 200A LTO BMS cuts out at 360A. Is your controller the SR483 or SR484? The SR483 is 300/350A. The SR484 is 400/460A. Either way I think the 200A LTO BMS looks correct. The ...

Don't think I've seen that.
