Re: We ordered a 2020 Mini Cooper electric!

We ordered a 2020 Hyundai Ioniq (38 kWh battery, 350 km town range and ~270 km highway). Was supposed to arrive next week but thanks to a certain pandemic it will be more like late May :( Ask for a discount :wink: We already got $3k off the sticker price - $49,990 on the road. Worth a shot though.

Re: How to connect 2 PV strings

My understanding with PV panels is that a series string can be paralleled with another series string, and the combined output can be fed into an MPPT controller. But if you were to add a third one in parallel, a fuse is required on all series strings. Diodes aren't exactly necessary because panels h...

Re: Where should I connect by Solar charge controller A or b?

If you are going to use a shunt, always mount it as close to battery (-) as possible. Other instruments might need a 0 volt reference, and you don't want to get that messed up.

Re: Wind and Solar vs Coal, Gasoline, Nuclear

Its not that easy. 60-80% of the power needed is continuous, reliable, “Base Load” , which even the most advanced RE powered industrialised countries have realised cannot come from Wind, solar , hydro, or any combination of them with batteries or pumps etc.. You have got to have a source that you c...

Check out the kits on sale at EV-Power.com.au
Rod has a good selection of gear and sounds like it's probably ideal for your situation.
Do, however read up on electricity and the significance of more than just voltage ;) You have much to learn.
Enjoy!

Re: Pv shunt trip

Pretty sure that you can't use interruptions on PV like that. You can use a manual isolator. In a dead short situation, PV just maxes out at Imax and stays there. But you can put a shunt trip in which is activated by something other than current, like a thermostat perhaps. Still not sure why you wou...

Re: Wind and Solar vs Coal, Gasoline, Nuclear

Pretty sure we can do both. Existing nuclear nations are well placed to do this. Nations who don't already have this complex, expensive industrial ecosystem in place would be better placed exploiting the zero emissions options they already have (batteries, pumped hydro, solar, wind).

2000 Wh, at a nominal 72 V suggests 27 Ah. A 72 V, 30 Ah pack (20s,6p) battery made from 35C cont, 60 C peak LiPo pouch cells might measure 260 mm tall, 170 mm wide and 215 mm long, and weigh about 16 kg. It will dish out almost 1000 amps if the conductors were up to it. Look up Sketch Coleman's ele...

Re: Electric Race Motorbike for NZ Bucket Class

If you want bulk power as a priority and don't mind spending a bit, LiPo pouches are the best.
Those Sammy 30Qs will sag pretty badly and get hot. They would last about as long as pouches in terms of cycle life.

Re: 1988 Honda Prelude conversion - fastest build log ever.

Quick update. The air conditioning compressor has been powered down with a PWM generator which reduces the energy consumption down to about 2 kW while delivering the same cooling power as before, so that's a win. The cell cooling power is awesome and works great. Got the front-rear weight bias and t...
