Two readings on the EV-ACS3205PE‘s 1.77-inch display tell you almost everything about a three-phase session: the phase currents and the energy delivered. Phase currents close to each other prove the car is really charging on three phases. The energy counter proves what the car actually received. Read together, they verify a 22 kW session in seconds.
Key Takeaways
- Phase currents are the three-phase proof: three similar readings mean the planned session; one near zero means investigate the car first.
- Energy is the wall-side record: check it against power × time; expect the car’s gain about a tenth lower.
- The listing states the screen size, not a field manual — exact labels follow the manual.
- The energy figure is a tracking record, not a certified meter reading; do not bill by it.

Phase Current: The Three-Phase Proof
A three-phase session splits its work across three phases. At this charger’s full rating — 22 kW on a 380–400 V three-phase supply — that works out at about 32 A per phase (the arithmetic behind the nameplate figures). On a healthy full-rate session, expect three similar readings, each near the level the car has asked for.
The pattern worth learning is imbalance. If one phase reads zero, or far below the other two, the session is not running as the balanced charge you planned, and the power falls to roughly the share the working phases can carry. Before suspecting the charger, suspect the car: the car’s onboard charger sets the draw, many cars accept less than 22 kW AC, and some charge on a single phase only. Then check that both plugs are fully seated. A persistent imbalance on a car that should accept the full rate is a question for the installer or support; there is nothing to open. Our explainer on single-phase vs three-phase charging covers why the phases matter.
Energy: What the Session Delivered
The energy counter is the wall-side record of the session, in kilowatt-hours. Cross-check it against the clock: energy should roughly equal average power × hours. As a labelled example, 90 minutes near the full 22 kW should show on the order of 33 kWh at the wall — and the car’s battery will have gained somewhat less, because roughly a tenth of the energy is typically lost as heat along the way. That gap is normal: the charger counts what left the wall, the car counts what reached the battery.
| Reading | Healthy pattern | If it looks wrong |
|---|---|---|
| Phase currents | Three similar values near the session’s rate | One phase at zero or far lower: check car acceptance first, then plug seating |
| Energy vs time | Roughly power × hours, the car’s gain about a tenth lower | Far less than the clock suggests: the car tapered, or accepts a lower rate |
| Late-session current | Falls as the battery nears full | Nothing to fix — the car is tapering |
What the Display Cannot Tell You
Be clear about the limits. The listing states the screen’s size — 1.77 inches — not a field manual, so exact labels and page order follow the unit’s own manual; this guide teaches the two readings that matter, not a map of every screen. No app is stated for this model, so the display and the car are the two session records you have. The energy figure is a tracking record, useful for a log or a rough cost split — not a certified meter reading. And the display cannot certify the supply: a worn, heating socket will not announce itself in these numbers — physical checks still matter.

The EV-ACS3205PE as Its Own Instrument
The EV-ACS3205PE is a 22 kW three-phase portable charger: 32 A on a 380–400 V supply, CEE five-pin plug, Type 2 car connector, 1.77-inch display, IP66 sealing. On a portable unit the display earns its place — there is no app dashboard behind it, just the screen, the car, and the driver’s ability to read the session at a glance, on any socket.
Frequently Asked Questions
Why does the current drop near the end of a charge?
Because the car asks for less. As a battery nears full, its onboard charger tapers the draw to protect the battery, and the display simply reports the fall — a sign the session is finishing normally, not failing.
Why are the three phase currents not identical?
Small differences between phases are ordinary. Act on the pattern, not the decimals: one phase at or near zero means the session is not the balanced charge you expected.
Can I bill someone using the energy reading?
Treat it as a tracking estimate, not a bill. The figure is the charger’s own session record, with no metering certification stated for this model. For a rough split of a known bill it is useful; for charging money by the kilowatt-hour, use a properly metered setup — see our commercial charging page.
