Re: watt hours / amp hours

Oh wow. I wish I had the facilities (and skills) to build an EV from an existing car. The electrical side wouldn't worry me too much but everything else would faze me - I can remove things easily enough given time and tools - but adapting *different* things to fit instead is where it all falls down ...

Re: watt hours / amp hours

Just a quicky Lee 4 x 12v batteries might weigh a little less than 8 x 6v batteries - as if you imagine a 12v battery being effectively two 6 v batteries side by side, you can dump two "end walls" and just have a thin cell separator in place - hence a 12v sometimes being a little lighter a...

Re: berlingo wont go

Hi Harry. I REALLY hope I am not teaching granny to suck eggs - if so, I apologise, not wanting to rattle cages. Having spent a fair bit of time playing with lead acid over the years though, the voltages had me reaching for a calculator. If I have made an assumption that I shouldn't (not standard Pb...

Re: Recharging points - increasing numbers?

Thankyou for that. I will have a look at what Kevin is doing or proposing to do. I remember the electricity reselling rules and regs though I admit I did not know they applied in this way. I am guessing that will have to change fairly quickly as it will be increasingly obvious that the inability to ...

Recharging points - increasing numbers?

I have had a bit of a read through and if I am about to make some sort of dreadful faux-pas, then I apologise in advance. Notwithstanding the wonderful idea of "free" which we all love to bits, is there not some REAL merit in encouraging jo-public - even if they are NOT an EV owner/driver,...

Re: New battery technology claims 300Wh/kg

Hmm, just done a quicky calc. 6 minute charge at 380v at 100 amps only = 3,800 watts. The charger must be MASSIVE. Gives one the feeling that a 235v 13 amp household plug wouldn't do much (In 6 mins) :shock: Now where did I put that mega horsepower single to 3 phase converter :?: Deker :| If it is ...
