This has been one of the common criticisms of electrical vehicles from critics and skeptics simply seeking to deny progress and ignore the advantages of electrical vehicles: “What about in 5 years when you have to spend $15,000 to replace the car’s high-voltage battery pack?”

It has by no means been a particularly convincing argument, nevertheless it should have gotten to lots of people. I usually determine that it stems from the expertise most of us have had with 12V batteries, which do degrade earlier than lengthy and wish changed each few years. Regardless of the origin, it’s clear that many individuals do assume it’s going to break the bank to exchange an electrical automobile’s battery pack.

However right here’s the factor: You’re in all probability not going to have to exchange it!

There are already EVs on the street which can be a decade outdated. A lot of them have a few years left on their batteries. And these are older EVs and batteries, each of which have improved tremendously in that timeframe. I recall a presentation a few decade in the past from JB Straubel indicating they hoped Tesla batteries would final 15+ years. They in all probability will!

A brand new research by”Geotab” is a strong effort to know what’s occurring and reveal the reality about carmakers’ EV batteries. The research analyzed 10,000 EVs in North America and Europe and located they solely degraded about 1.8% a yr on common. With the vary EVs begin with nowadays, which means they might simply function for 15 or 20 years with no need their high-voltage batteries modified. For sure, many vehicles don’t stay that lengthy. Whether or not due to accident or simply the whole lot beginning to collapse, vehicles are sometimes able to be ditched after a few many years of possession. So, who wants a battery that lasts perpetually?

So, whether or not a battery alternative would price $3,000 now or $9,000, it doesn’t actually matter, however you’re not going to go changing your battery. It’ll be simply wonderful.

Notably, some electrical vehicles had batteries that have been anticipated to degrade lower than 1% a yr. Which means you may maintain your electrical automobile for 30 years and it’d nonetheless have greater than 70% of its authentic storage capability. I feel that’ll do exactly wonderful for the overwhelming majority of us.

“The report underscores that higher EV use doesn’t mean higher degradation, but more fast-charging might. Geotab noted a correlation between greater DC fast-charging use and faster-than-average battery degradation—especially for vehicles in hotter climates,” Inexperienced Automobile Stories writes. That stated, one other group’s analysis discovered earlier this yr that quick charging didn’t make EV batteries degrade any sooner than with sluggish charging did. Both means, once more, it actually doesn’t matter — our EV batteries are going to carry up simply wonderful.

In case you are involved about battery degradation, although, there are some easy tricks to observe. I wrote an article three years in the past (three years in the past?) explaining that it’s finest to maintain your battery round 50% state of cost if you wish to actually maximize its lifespan. Nonetheless, protecting it between 30% and 70% is extra sensible than protecting it between 45% and 55%, or 40% and 60%. So is protecting it in a cooler place somewhat than a warmer place. And, once more, it doesn’t matter! Your battery will not be going to degrade to the purpose the place you want to spend hundreds of {dollars} on a alternative. (Disclaimer: There can all the time be excessive, area of interest eventualities the place the battery does degrade an excessive amount of too early, however that’s solely anticipated to be a tiny fraction of EV drivers.)

In brief: fear not, and be at liberty to inform EV skeptics, critics, and laggards that additionally they needn’t fear.
