I have reluctantly accepted that a lightly used tethered cable cannot be expected to last more than 3.5 years
Cables have to be specified for all sorts of duty and environments. So the degradation to worry about would be UV ageing of cable insulation polymers (unlikely concern in the UK); mechanical abrasive damage to the cable insulation (doesn't sound like your scenario) and connection/disconnection cycles specification of the plug (again not exactly what you describe). I would the cable manufacturer to have modeled a worst case user using the cable every day (eg a commuter) and possibly in a much hotter climate (eg California). Personally, I wouldn't be changing my cable for a long time. For end of useful life, I'd expect to see visible ageing of the cable insulation and/or to feel unusual warmth at the cable plug, indicative of connector wear.

I’d be interested to know where the mentioned 3.5 years came from 🤷🏽

3.5 years is how long my tethered cable lasted before the CP wire broke 1/3rd way along within the cable structure. Cable had only had careful light use and outward appearance is like new. Not exposed to any extreme conditions. This appears to be a weakness of the cable design? The warranty on replacement cables is 1 or 2 years. I saw someone report their cable suffered a CP failure after just 1 year.

If you didn't accidentally/unknowingly driver over or snag the cable somehow, that's one very poorly quality constructed cable. I presume the cable was not being repeatedly coiled and uncoiled which might have induced metal fatigue?

Maybe the cable was defective, it’s definitely a possibility. Just from using them for general charging use I would expect one to last much longer, and as mentioned the only time you might experience problems is after accidental damage (running over etc).

No never driven over, walked on, snagged or twisted. When not in use stored as large loops rather than tightly wound around the Zappi. Located outside but out of direct sunlight and sheltered from wind and rain. About as good as possible and only used about once a week.

I thought it indicated a defective cable but MyEnergi disagree. I have not seen a supplier offering more than a 2 year warranty and many only offer 1 year. Disappointing but thats how it is. The likes of ecoHarmony and EVcables are about half the price of MyEnergy but I then disappeared down the rabbit hole of IP and UL50 ratings and suppliers instructions not to charge in the rain, hence this thread.

The ev cables website states, "Outdoor-rated units are safe to use in all weather conditions." So that is certainly all public chargers and professionally installed home chargers.

The opposite is possiby true here - if you buy dodgy equiment or have it installed by someone who "thinks" they know what they are doing - expect dodgy results.

Other than that

It was ev cables web site that said the IP54 charging cable I was looking at should not be operated in the rain as it is only splash proof. Could not see your quote but maybe they were talking about the EVSE rather than the cable?

I do not profess to be an expert and am only stating what suppliers or testing organisations have published on the web.

Time to let people make their own decisions and end the thread I think.

I have been watching this rain issue about cables but my main concern has always been about rain in and around the actual charging port causing problems as the plug itself slopes into the port and naturally will send rain into there.

After some thought, I devised a simple shield that can be easily attached to the cable/plug in rainy weather and will divert any rainwater away from that area. It is a simple rectangle of polystyrene sheet with a pipe clip attached that is sized to fit the cable. ( picture 1 ). It is shown here attached to the cable/plug ready for use. ( picture 2 ). It's easy to plug in as normal with the shield swung downwards ( picture 3 ). Then swing the shield around and upwards into place to protect that area from rain. ( picture 4 ) Of course, this particular design may only work with an Ioniq, but the concept can probably be adapted to fit most other cars. As it is polystyrene it will cause no damage to the car or paint. Might need some extra clips in stormy weather but so far it's been OK and stays in place.

A good point. The charging plug and socket are clearly designed with the intention of the plug sloping downwards to shed water. That is how my plug holster is oriented when the cable is not in use. It seems perverse that the car sockets result in the plug sloping towards the socket. I wonder how the plug and socket were oriented during the IP testing?

Your solution looks as if it would be affective and would also provide the extra protection from rain recommended for IP54 equipment. Only potential issue I can see is if the cable is wriggle about in high winds it might put stress on the termination into the plug and, over time, result in a broken wire?
