But doesn't regenerative braking mean less brake wear = longer brake life? Or do manufacturers take that into account and use less meaty brakes?

If that Tesla clocked up 320 thousand Ks that quick its doing very long haul trips - so the brakes are being used a very low percentage of the time relative to the kms driven.

 

By contrast a car based around Auckland would have plenty of stamping on the brake pedal - so a high proportion of brake usage per km.

 

I understand that regenerative braking would greatly reduce actual brake wear.

the whole braking and regeneration thing is something I will have to get used to especially the different freed back through the pedal.

Brake-by-Wire if anyone interested is explained here:

Agree that those systems in Hybrids and Evs feel significantly different.

 

In Prius C it feels as if it requires less efforts and much more "instanteneous" vs other old ICE Toyotas

I imagine so, and with automatics the norm, engine braking in combustion powered cars is much less prevalent than it used to be.

 

Doesn't explain the shocks though

Nice but how are they generating the Hydrogen??

You can set the Tesla up to be pretty aggressive on the regenerative "engine breaking", so if you drive with your head (that is, leaving some room to the car in front of you), you can probably keep the speed you need (even in start/stop rush hour traffic) only utilising the gas pedal.

Impressive, although take with grain of salt given that's just a sample size = 1. My N=1 experience is a 3y old 2nd gen Leaf with only ~30k km but battery's already down to 80% of original capacity...

 

 

Whoa!!! 

That's not a happy story. My 2015 LEAF is now close to 15,000km.....12,000 of them mine...and the battery is 100% SoH. 

You sure you have a Gen 2? Is the control unit the rectangular 'normal-looking' engine cover? Or the squareish aluminium bread box? 

Where was it sourced from? A hot place?

Some people drive with ECO off...and do less regen and use the brakes more. 

Personally, I always have ECO on (why give away any range at all?) and I use it to slow down for intersections or anything that needs gradual slowing down for. The brakes are there if I need to finish the job faster. :-)  

However....I've noticed braking regen generates a lot more power than rolling regen. Going down the hill at Piha I can gain a full 0.25 kWh or more just from the brakes alone....in (actually - just a few seconds) minute or so. That's close to fast-charging speeds. 

I have yet to experiment with turning ECO off on a steep downhill and using the brakes for regen instead.....I'm thinking...."Why wear out the brakes?".....It's not that big a deal. :-)

Hydrogen fuel cells are not a popular option amove EV fans. The hydrogen is made by burning natural gas.....and you can't do it at home...you have to go to a place ot buy it - always. It seems to be a make-work project for petrol stations who won't be required once cars are electric...and people charge them at home and / or via solar panels. 

So though the car is essentially zero-emissions, making the fuel for the car isn't. 

 

Large, cheap batteries should see fuel cell die as a technology.

That's pretty much how I drive. I tend to watch in amazement as the queue of tailgating cars and vans meets the queue of cars and vans trying to get onto the motorway....and everyone has to pretty much stop.

It's so incredibly dumb to keep driving like that....day after day after day.....and never learn that if you leave a gap the other guys can get in and EVERYONE just keeps on rolling. For an EV driver this style is even more natural and efficient.  Of course, it is more effcient with pretrol and diesel, too, but people are so used to wasting those most people don't even seem to think about it.

To be fair producing electricity isn't zero emissions. There will be an impact what ever is used. More folks may feel better regarding HFC as the range anxiety is largely gone. HFC is much less an impact to what we currently have but not as good as EV with regards to impact in some countries.

True. in NZ electricity is 80% to 93% renewable......though that includes some geothermal that isn't zero-emissions. 

I still prefer to charge at home for super cheap than pay what amounts to quite a bit for hydrogen....and there aren't any distributors of that in NZ that I know if....and OZ there are only one or two sites.   

But if you like it, buy one. :-)
