ChargePoint show questions

Hi,

In Huntsville, we've had several J1772 plugs destroyed by people who ripped them out of the holster tearing off the latch and jamming the 'presence' switch. The unit remains unusable until a repair technician comes out. I also have posted the old GE J1772 being abused. Have you considered:

1. Signage or video showing how to remove and insert the J1772?
2. Setting the holster retention to 'give' instead of letting the J1772 latch break and switch jam?
3. A really strong locking latch on the J1772 it will damage the owner's car if they try to over power their socket lock? (OK, so I'm still pissed at the damaged J1772 still not repaired in over a week at the Huntsville Whole Foods.)
4. How about a J1772 that when over powered, simply 'falls apart' without damaging the parts? So the latch simply falls out with perhaps a carbon fiber thread so it won't 'walk off.' Prying the J1772 insert cylinder so it just pops off with the carbon fiber thread. Then show a video of how to put it together again.
5. How about a screw-tightened, second connector at the end of the cable end of the J1772 handle so a damaged J1772 can be easily replaced?
6. Any thoughts about adding a Tesla plug?
7. Have you thought about providing a DC charging option using the J1772 and/or Tesla connector? This could significantly reduce the charge time at a station. NOTE: I am not a fan of the Franken-plug.
8. How about facial recognition, camera so the *ssh*le knows we will find them ... <GRINS ... still pissed.>

It's sad that we need to find solutions ourselves to protect us from thieves and criminals. Why not have cameras and catch and arrest these people. If they are doing that, probably committing a lot more crimes, and should be in jail.

I don't like guns, but do understand why so many Americans carry them.

Perhaps the ChargePoint rep might show a collection of damaged J1772 plugs and sockets. Invite them to discuss in-house or standards groups addressing the weaknesses of the J1772 plug?

I only have the Tesla connector to compare and contrast with the J1772:

• Mechanical latch vs a Tesla 'hook' - the Tesla connector has no moving parts in the plug which means no breakable latch.
• Short Tesla cable nearly impossible to run over - we've seen J1772 housings cracked from extreme stress that looks like someone drove over, smashed, or crushed the plug.
• Some way (automated phone system?) to other charging outlets with direction to public NEMA 14-50 or EVSE.

Tesla connection is the benchmark, of that I will not argue.
J1772 latches broken is old news around these parts, also presents a defined safety issue.
Unfortunately I can foresee not only the malicious vandals as previous experiences, but possibly ill disposed ICE drivers joining the group, particularly with the recent gas price surge, observing EVs charging for little if any cost.
I do like the idea of a camera and additional lighting in those areas, if nothing else to enable a little more security.
