As an expert in the charging pile industry, EVDANCE has rich experience in the development and manufacturing of intelligent EV charging solutions. This is where we turn our engineering insights into knowledge and share them with the global EV community.
An EV charger relay has no lifespan in years: it wears by switching operations, load and environment. The warranty and service terms are the buyer’s real figures.
A welded contactor fault means the charger cannot prove its main switch opened. Keep the unit out of service, record the fault and book the repair.
A circuit breaker protects the wiring and trips on faults. A contactor is the charger’s working switch, opening and closing each session. Different jobs — here is the split.
‘Smart’ and ‘dumb’ are trade slang, not official classes. Smart means a control layer — app, schedules, access, data — in some mix. The spec sheet, not the label, says which.
At a managed site an internet outage pauses the management layer — authorisation, live status, billing sync — while running sessions normally finish. Details are platform settings.
Yes — a connected charger can be attacked in principle. For a site operator the practical skill is recognition: sessions, users and settings that are not yours are the early signs.
No score grades a charger’s security. Its posture is set by the maker’s update policy, the platform, the account layer and your network — judge each from evidence.
OTA updates travel over the connection a charger already has. What makes them trustworthy is the policy behind the download: signing, staging and support length.
An RFID tap only presents an ID — authentication is the check behind it. Where that check runs, what it looks at, and why a read card can still be refused.
4G on a charger means its own mobile-data link — a modem, a SIM and a plan. Who owns each, and what happens when one lapses, is the part buyers miss.
