From the translated WeChat release and that image, I am now guessing that perhaps the Cybervault is a ruggedized and "tamper resistant" L2 EVSE for destination and public chargers, potentially with some kind of payment infrastructure, but basically a rugged, "secured" EVSE for use in "public" spaces.
They'll probably sell a bunch to Cybertruck buyers in the US too to put in their garages "because cyber" but it likely won't have any technical advantage over a V2/V3 Tesla EVSE unless it supports higher L2 charging speeds, but with the WeChat PR I am guessing this is targeting trendy public spaces in China for EVSE sales.
