If they can sell them at a decent price in the US then they will have a huge market to sell them in.

Lithium batteries' big unanswered question

https://www.bbc.com/future/article/2022 ... d-question

As the world looks to electrify vehicles and store renewable power, one giant challenge looms: what will happen to all the old lithium batteries?......

An update on recycling of EV batteries
https://www.thecooldown.com/green-tech/ ... batteries/

[Khundon1975]

My Kia has done almost 50k miles in 2.5 years and we’ll change it soon for another EV with a bigger battery than the 64Kwh battery it has now. It’s a Lithium-ion polymer battery which I have no doubt will easily go on until 150k miles maybe more. Even then it could be recycled as a power bank for a house somewhere, if someone buys it
for that purpose. Hopefully by then EV battery recycling will have advanced enough that these batteries have a value when recycled.

There will soon have to be a cheap and safe system for recycling EV batteries as we can’t just dump them and hope there won’t be a problem for the environment.

On EV battery degradation (LFP chemistry), our MG ZS (2022) suffered less than 0.83% battery degradation over the past 1 year / 20k kms.

As we average, or best the 360 kms per charge, now states 357 when fully charge and in ECO mode.

If using WLTP rating of 320 kms, then about 1%
If using NEDC rating of 403 kms, than only less than 0.74%

Time any of those by 8 years, and less than 8% over the warranty period.

Along with 8X our savings of 40-54k baht on petrol last year.
320-430k petrol savings expected while just under 8 year warranty.

We charge with excess solar, so IF, all kms local, then a savings of about ฿54,000 for the year / 20k kms (91 @ ฿38/L).

Our actual driving, was O&A for 9366 kms, of which 5366, we used CS @ ฿7.5/kWh = ฿6,200 vs ฿25,000 if using petrol for 9366 kms. We saved about ฿47,800 baht for the year, from petrol alone, vs the same ICE version of the ZS, that we 'did own'.

I minus'd 4000 kms off the 9366 total, as 8 trips overnight & CS used, with 500 kms per trip from solar. Beginning from house @ 100%, returning @ ~20%, so about 250 kms each way X2 X8 = 4000 kms charged by solar. Rarely use the grid to charge the car or MB.

Many of the mall vendor machines are actually slow chargers, so no real advantage to use.

Do you think that might have changed now? There always seems to be cars using the service at Bluport. And I think there are 6 chargers, not 4, and two different types of charger. Just my observations when driving past on my way out.

[Dannie Boy]

I’m sure they’ll be a minimum of a 7kw charger which is what you can have fitted at home providing you have a 30 amp supply and roughly double what a standard socket outlet will provide. Some of the top spec cars can accept 150kw+ charges, so bound to be a lot lower than what they can charge at.

As with everything, need to read the 'not so fine print'. Some of the slower charger/cables, charge by the hour. And not cheap (besides simply slow) compared to charge by kW actually used. ฿50 or ฿60 per hour for 7 or 22kWh is no bargain. Most DC fast chargers are ~฿7.5 per kWh, unless in higher end mall/location, then might charge ฿10.

When our car/ZS, will accept ~76kWh, so on most faster DC chargers, at least 50kWh, we're never there for an hour, (46.3kWh useable battery), and will leave with up to 32kWh (20-90/95%). MG4 will accept 117/135kW .... impressive for not being hi-end car, if you can find a cable offering that amount.

A couple at Bluport are DC fast chargers. Haven't used yet, and doubt if we ever will. Can make it to HH round trip from home/PKK without charging. And if coming back home from up north, usually topped up before leaving Krung Thep area, so don't need to charge to get back home/PKK.

Can you please explain how you divert excess solar from the grid to your EV charging? Thanks.

The EV fanboys on this thread continue with their delusions.
Almost nobody wants to buy one for very good reasons. They are expensive, unreliable, severely range-limited, heavy, a fire risk, and depreciate like falling masonry. And they are most certainly not environmentally friendly.

Divert ?
Simply plug it in to the house outlet.

Seems to be more of this happening.
3rd party 'fire and theft' might become more expensive
I wish the 'hydrogen cell' would hurry up.

[Dannie Boy]

Another reason to also hope that they manage to crack the Solid State Battery development because apart from all of the technical advances it’s supposed to offer, it’s other main advantage is that it’s much safer and not prone to catching fire.

I’m not anti-hydrogen cell technology - far from it, so if the industry can support two types of technology that would be great for the consumer. The biggest drawback that I’m aware of re hydrogen cell technology, is being able to develop the infrastructure to support worldwide adoption - scaling up hydrogen production is even more of a challenge than EV charging stations!!

At current sales volumes, EVs are heading towards 20% of global car sales by the end of the year which is hardly "Almost nobody".
If EVs were actually as bad as all the negativity you see on the Internet and in the UK press, they would have died a natural death years ago.
What you are seeing is huge amounts of lobbying money being spent by the vested interests in the fossil fuel and IC motor industries who never thought this technology was going to advance so quickly.
Renewable energy is now getting so cheap that throwing money away to the Middle East for fossil fuels is absolute stupidity.
