How long EV and home backup batteries can last

Lithium-ion batteries used in modern solar systems and electric vehicles (EVs) can last over 15 years and still have plenty of use after consuming their rated life cycles, as long as they are treated according to their specifications.

South Africans on social media often respond sceptically to announcements of new EVs, asking what new buyers would do if the battery packs up within a few years.

The most affordable EV in South Africa — the GWM Ora 03 — consumes 16kWh per 100 kilometres and has a useable capacity of 45.5kWh.

At "From R686 950", this Is truly not affordable to the average commuter travelling 44km per day.

No table summarising the article?

I am very sceptical, that is because, and as you well know, the govt is typically normally unable to satisfy domestic and commercial demand for electricity. The battery may be able to sustain a charge repeatedly for years, however, if more than a few cars / backup get sold, the supply system should collapse completely. That's the real problem.. And not only in sunny SA, but even in first world counties too.

Do we have ten years of history? Are car manufacturers willing to replace batteries which fail? Are we taking one test car and using that as our argument as the standard.

Yes, we do. Tesla model S has been around since 2012. Others even longer. https://www.motortrend.com/features/how-long-does-a-tesla-battery-last/

Pylontech, for example, have been making backup batteries since 2010.

And then there are external tests too:

ITP Battery Test Centre Reports

These reports provide analysis and discussion of the process of installing the batteries and testing data.

My UK cousin sold her 2008 Pruis to a gent at her garage in 2018. He drives it every day. Its not Lithium-ion though, but NiMH.

Tell us you know nothing about battery technology without telling us

There is way more to battery lifespan's, than just cycle count.

You need to keep them in a healthy temperature range. So no parking your car outside everyday in the African sun.

You also don't want to be fast charging them all the time.

Many electric car manufacturers will use cheap batteries, and skimp on battery cooling, to maximise profits at the cost of the car's lifespan. Just have a look at Nissan leaf or EV Golf battery lifespans in general.

Very true, cellphone batteries are even worse, since manufacturers install needlessly tiny batteries that don't make it through the day, or even needs to be charged twice a day.

The last 20% of a battery does the most damage, don't discharge or fast charge a cellphone battery on a regular basis.

The battery in my TV remote is just as bad. I need to throw it away every year or two. And that's not even to mention the battery in my little load shedding torch. That guy only lasts a couple of weeks.

Your 13 year old cellphone battery doesn’t have active temperature or even general managements.

It just runs flat out until it is dead and then charges flat out with whatever you plug into it and does so until it dies.

There is little to no intelligence involved which is why now it’s pretty useless.

Most EV’s and Home battery solutions are not only entirely different types of batteries chemically but are also managed very differently.

Sorry that was a typo and is meant to read as entirely different.

Show me someone who will keep their car for 13-17 years, just because the battery still works. Which is exactly how long it takes to start recouping the upfront purchase cost.
