Re: Soyachips’ Electric FZR250

Under heavy loads the headway go down to 2V so the minimum should be 48V.

Re: Soyachips’ Electric FZR250

24 cells in series so the input range of the DC-DC needs to be ~60V-87.6V with ~13.8V out preferably with constant current.

Re: Soyachips’ Electric FZR250

Ah I had a quick look yesterday but your main traction pack doesn't fit into the universal input AC supplies.
So you need an isolated dedicated DC/DC - not just an AC/DC with DC shoved into it.
That makes it a bit more expensive.

Re: Soyachips’ Electric FZR250

4 x headway is 12.8V nominal and 14.6V charged.
So anything from 13V-14V is ok.
Most of that would be for the headlight+brake light.

So 100-150W for a DC-DC?

For those who don't know the Aptera is like a plane without wings. They went under some years ago but now they have been restarted. www.aptera.us The new Aptera ev is now sporting solar so they claim that it can do 60km a day without ever needing a charge. So I hope all those environmental protester...

Re: Power Steering failure when in use battery drops 13.5 to 8v

The 12V should be able to cope with the load. The DC/DC should be able cope with the load too. 8V is quite a drop - last legs in fact. Check all your 12V connections are clean and tight. Am I to assume the battery has been in there for a while since I see some posts from a few years back. I'd guess ...

Nidec In wheel Motor

Soon (2023) to be released Nidec's in wheel hub motor. 100kW 32kg However is only "compact" enough to fit in 20" rims :lol: It has integrated internal reduction drive. Not too sure if you need to do 200kph to get 100kW as its not specified. https://www.nidec.com/en-Global/product/news/2019/news0305-...

Re: Error 05

Most components wont survive 20A in a shorted state.
I'd go with the relay contacts welded or something outside the inverter (user error).

Re: 20 x Leaf Cells

Just as a side note I have been using a Meanwell HLG-320H-42A power supply to charge them in groups of 5. The idea is that when the pack contactors are on the 20S pack is ~152V. But when the car is off and the contactors are de-energised the 20S pack is broken into 4 x 5S packs. So 38V nominal and 4...

Re: AC 3 phase motor fee spinning

Even with 80kph as the nominal voltage 140Vdc that's 18kW nominal and ~55kW peak.
More voltage - more power.

You'll have to check what the upper and lower cut-off limits are in the Wavesculptor.
