Thread: EV general discussion

Cheaper is certainly better. The Hyundai Ionic is well priced for a local runabout.

Unfortunately time will take its toll on these batteries even if not cycling much.

If the pack has been kept at 100% SOC without any cycles, @25C it could loose 20% of its recoverable capacity in just one year!

Storage in cool environments is much better. For long life you will want the battery sitting at <25C and at <60% SOC when not in use. How many people will sit their cars at 100% SOC in the hot sun!?

Tesla has an active cooling system even when the car is parked to help maintain long life, and they discourage frequent >80% charges on the screen with warnings. So that's probably why they are holding up well on average.

At 52K compared to 25K for the petrol advertised at the moment.
27K is a lot of petrol.
Re local runabout Honda Jazz perfect local runabout at 17K auto. so 35K is even more petrol.

Regards PhilipA

50k is more than the medium years salary.
for a local run about....

In Australia salesmen are directed to steer customers away from EV and into ICE , theres a lot more money in ICE with servicing / parts etc . The same would apply if an EV has a fault , they will go out of their way to not fix it, & say " see I told you" EV are not advertised in Australia.


USA Leaf Ad




Tesla ad , doesn't do it for me

Lithium should not be stored at 100% 3.2V is nominal, about 50% SOC , they should store stable for years.

Right, but the point is even without cycles , if your battery is sitting in 30C heat half the year and often parked in a higher state of charge than 50% , then you will be loosing capacity year on year regardless.

You must have lost a smidge of capacity in two years - no? Some of that will be from age alone.

So which one is going to be found in your garage?



A mate picks up his RAV 4 hybrid next week,after an 8 month wait.It will be interesting to see how it goes.

Apparently its AWD,and has electric motors for the rear wheels,only used when needed,and i presume when the battery has power.So it won't last long in 4WD.

Five years unlimited mileage warranty plus another 7yrs on the electric motors,and 10yrs on the battery.

He did say the plug in model not yet released in Aus uses more fuel and battery power due to the weight of a much larger battery.

Top of range model,about $50K
