Re: Battery Modules Questions.

Looking through the build I'm thinking what you need is a liquid battery pack that can just be poured into the car to fill all the nooks and crannies

Also if I add all the number of cells in the spaces you have listed I only get 186 cells.
There are more cells in the picture /link.
That list appears to only have the larger spaces

Re: Prelude conversion project - some questions

What he said^

But that being said the diodes really shouldn't be carrying any real load, they should only be used as logic control for relays/contactors etc

Re: Prelude conversion project - some questions

I would say parallel would be best, or after if you really have to be in series. I think that once the refrigerant has gone through the heat exchanger it won't have anything left to give for the poor people in the car. The compressor/condenser should cope fine with the extra load from a parallel sys...

Re: Prelude conversion project - some questions

That will work but the a/c will only work with the key on. If you want it to cool while charging etc it will have to change. Also the system will trip out on low temp really quickly if the blower fan isn't going (evaporator will turn to a block of ice) and you won't get good cooling on your pack. Ma...

Re: Prelude conversion project - some questions

I might be able to totally bypass this compressor control unit since the sensors are pretty basic (NC sensors). Yep, you can bypass it/replace it its only there to make it so the a/c only works when the motor is running (ign coil input) and the alternator is charging (alternator input) I assume its...

Re: Prelude conversion project - some questions

I hope there is a temperature sensor in the blower unit, otherwise there is a risk the evaporator will ice up pretty quickly... The part on the diagram labeled thermostat is the low temp control for the evaporator And yes the module will most likely need a coil negative input (so a signal that swit...

Re: Some pictures of the Energica Ego race bike, fairings off.

What voltage are most ev bikes? 48v? Because if so then that's low voltage anyway.
Also the 12v battery regs are for cars, bikes are a grey area on ev compliancing, so that's another loophole.
And also also what year were the bikes complied vs year the ncop14 was put in effect?

Re: 2011 nissan leaf

Aren't they exchange? Nissan has to make money somehow and a couple grand for a 24+kwh seems too cheap to be making a profit if it's filled with new cells. So I'd say they are probably 2nd hand cells that have been tested or Nissan are selling the exchange cells for a mint. Also I thought they had b...

Re: Prelude conversion project - some questions

Also manufacturers would have to make sure everything is reliable for 100's of 1000's of kilometres and crash tests etc. They have to put their name up there next to it and if it bursts into flames and burns a skyscraper down they can't really just say "oops". In terms of cost is basically what's ha...

Re: Nissan Announce Pre-ordering for August release of Leafs

Sorry, yeah 40kwh.
110kW of power and 320Nm of torque, and equipped with a new 40kWh battery giving it a claimed range of 270km between charging


It's not actually the latest and greatest leaf regardless what the marketing at Nissan Australia say. (the e+ at 60ish kwh is the actual new model)

Re: Nissan Announce Pre-ordering for August release of Leafs

It's the 40kw and there aren't any real options (I think colour is about it), So 1 flavour and it's $49990 plus on roads.

Re: Prelude conversion project - some questions

I'd recommend the black /yellow trace coming from fuse 12 for "ign" because it's fused. Less burning the car to the ground if there is a short.
Everything else on that fuse is being ripped out or was never fitted (except the speed sensor)

I would think in parallel would be the way to go so you aren't making the pump work hard, having to deal with possible hoses popping off/bursting and pumping hot water into a pack you are trying to cool while the first pack is below freezing, Etc If each pack gets a different flow rate because of di...

Re: Lead acid to lithium conversion

You could get a pre built 48v lithium pack, like what's used on the electric pushbikes, and put a couple in parallel to get the current/capacity required.
