Re: EV-Only "Fuel" Tax On The Govt Agenda

The report can be read here: https://infrastructure.org.au/wp-content/uploads/2019/11/Road-User-Charging-for-Electric-vehicles.pdf I think we all agree that there is something deeply unfair about the current road tax system. It's a pity the report missed it's own recommendation on what has been wor...

Kudos for the exoskeleton concept though. Maybe that's why it's cheap despite the exotic materials?

Re: Leaf Range *no discussion*

Our new to us Leaf has 93,000km, SOH 83%, 1st capacity bar lost, GOM 114-119 at 80% charge. Hi JeffB , I assume yours is the imported one? What year model is it? There's no way Oz Leaf has this awesome stats (unless the battery just got changed under warranty)!! That pretty much confirms the newer ...

Re: Simple (to use) wall mount =<7kW open network

Sigh... I wish local councils are more supportive on this one. To make it 'slightly' future proof, those non-network mennekes wall chargers should be not too expensive, me naively think. Even 15A Australian wall socket will do (that opens 24/7). The problem with the 'RREV' (a.k.a. gen-1 Leaf), the b...

Re: Hyundai Sales Tactics

... The cars don't have much margin on them, and the servicing is almost non-existent. So you can see that a dealer would be better served by selling you a petrol car, or moving you on to another dealer. With this in mind, we have an excellent relationship with our local dealer. They have a mindset...

Re: Are hybrid bikes worth the money?

Echoing what Mike has said. However, without suspension, make it easier if you're a DIY-er though, i.e. long term maintenance.

Mine has run close to 50,000km (over the top details here).

Re: Offgrid solar project

Is there a buck converter that does say 96V in to 48V out with 600W+? I had a quick look and didn't see one. The other issue I have is a simple buck converter has a tendency, when they fail, to supply Vin to Vout. So 80V input to a 48V inverter would be bad. Ah yes, you're right, the only one avail...

I've been using 'el cheapo buck converter for mine (no MPPT) and has been working well for more than two years so far. Since I got the PV on the cheap, not worth spending the money on the MPPT controller. Utilisation factor is very poor, but not a concern for my purpose (I just need extra Wh for win...

Increased Internal Resistance

While the crowds want more battery capacity, I'm content with more fast charger networks, i.e. stops more. However, I recently found out the degraded battery of my Nissan Leaf considerably increase (fast) charging time, i.e. more than doubled!! Yikes!! :o My 'Hx' degrades pretty bad, and slows down ...

That mass includes the charger, DC/DC converter, HV switch gear, cooling system and related control electronics. If you take that mass out of the system you have something closer to 200 Wh/kg.

Hi Raoul,
