This Material Improves Charging Connector Wear By Up To 40 Times



Is it some sort of magical material?

Xtalic Corporation enters the EV market with new materials that improve charging connector wear by up to 40 times

According to the press release, the XTRONIC and LUNA nanostructured alloys enable one to lengthen the service lives of electric vehicle charger connectors to 10,000 charge cycles in high- to normal-force applications, compared to traditional silver-over-nickel-over-copper construction that wears through after 250 charge cycles.

Feel free to give us sign in comments about how well yours charging connectors works over years of using EVs. Whether after 250 uses there are any problems with connection?

The Xtalic alloy is promised to significantly enhance the connectors’ hardness, durability, and corrosion resistance and withstand temperatures of 150° C or higher due to a carefully engineered crystal structure.
More at Inside EVs.

I call BS on the 250 number. Some EVs have already hit 4,000 charge cycles.

Seems to be the norm in the comments. Of note:

Threader said:
Proof that you guys will publish about anything “compared to traditional silver-over-nickel-over-copper construction that wears through after 250 charge cycles.”
I think he's onto something there, but it's not limited to Inside EVs.

On the plus side they did say what Xtronic and Luna are. Look how long it took us to find out what Retsyn is!

What the heck is Retsyn?

After 7 years of 5 days a week charging (minimum) my Volt is at 1820 charge cycles. Is that more than 250?

Great marketing technique!

Create a false problem out of thin air . . . . then sell something to correct it

250 could have been a typo. More and more I'm reading stuff that hasn't been proofread, even in print magazines where it almost never happened in the past.

Maybe someone at Inside EVs will read the comments (obviously the possible mistake has been noticed) and do some fact checking.

Or not......

It's entirely possible that Retsyn will extend the life of the contacts. ;)

A typo for what? That's the figure that matches the "improved by 40 times" of the headline.

Maybe the 250 charging cycles only applies when you do the Hokey Pokey.

I'm at somewhere in the vicinity of 3500 plug/unplug cycles. Do I get a prize???? (LOL)

I plug about 3-4 times a day! Two years now, so about 2,500 plug/unplug. I have already fried the OEM EVSE at the 21st month (plugging both to 240V or 120V) and now starting with my next one from Amazon.

The problem with the first one is the circuit, not the wearing off of the plugs, I tested them.

The J1772 standard specifies the connectors are good for 10,000 cycles, not unlike other may other robust electrical connectors.

"Design Life – The coupler shall be designed to a minimum of 10,000 cycles of mechanical operation. The coupler performance shall not be reduced by the environment conditions specified..."

I'm probably about 1500 cycles on the car, less on any one EVSE plug.
