Title: Techie question about charging with a surge suppressor
Post by: heroto on November 03, 2022, 06:36:00 AM
120v AC (US)
Tried to charger through a surge suppressor. Nothing
Bypassed the surge suppressor: Charging as expected.

(In case it matters, the suppressor is a Tripp Lite ultra)

Please, experts only, thanks

Good to know that I’ve come to the right place.

Suspect this is not an issue w/ cheapo (voltage) surge suppressor which is typically MOV (Metal Oxide Viristor) based that clamps spikes above line voltage...for 115VAC a typical threshold is about 175 volts.

Suspect issue at play is because device is not a cheapo surge suppressor but an enhanced variant which incorporates line filter(s) that impacts voltage rise-time as seen by Energica charger...circuit diagram required beyond this point to understand exact mechanism at play...

The charger is not really a "charger". It's more of a glorified extension cord with a crap ton of safety measures built in. It does not need surge protection, it is a surge protector, a very expensive one sadly. So when you plug it into another surge protector, it is mostly likely wondering what the hell you are trying to do and is having none of it. They tend to have attitudes like that, especially when it comes to grounding.

I am not familiar with the suppressor you are using but if it lacks ground reference (or floats the ground) this will prevent an EVSE from initiating a charge session.
*(Not a suggestion do not try)* I suspect if the ground pin of the EVSE was hooked directly to the wall outlets ground pin it would work correctly. No clue what the side effects of that might be

Same reason running a EVSE off a generator causes issues. Solution there is to jumper the ground and neutral of the outlet.
