The EV-ACS3210E’s app reports the energy of each session in kWh, measured at the charger — the wall side of the session. Read it as the figure your bill is built from: it will sit a little above the kWh your car says it received, because conversion losses happen between the wall and the battery. It is a tracking figure, not a certified billing meter, and used that way it earns its place.
Key Takeaways
- The app reports wall-side kWh per session — the figure your bill follows, and always a little above the car’s own number.
- Use it to cost a session at your own tariff, spot a charge that ended early, and keep a simple household log.
- The current setting changes a session’s duration, not its energy; the record shows both, separately.
- No metering certification is stated for this unit: the figure is for tracking, not for billing anyone exactly.

Two kWh Numbers in Every Session
Each charge produces two energy figures. The charger counts what left the wall. The car counts what arrived in its battery. The wall figure is always the larger, because some energy is lost as heat in the AC-to-DC conversion and in the cable. The gap varies with the car, the temperature and the session, so no fixed percentage describes yours — a measured figure beats an assumed one. Our explainer on how many kWh it takes to charge an EV covers the battery-side basics.
| What you see | Where it is measured | What it tells you |
|---|---|---|
| Session kWh in the app | At the charger (wall side) | The energy you were billed for — the input for cost |
| kWh added, shown by the car | At the battery | What the car stored; always the smaller figure |
| Session duration and current setting | The charger’s record | Why a session was long — a low setting stretches time, not energy |
| A week of sessions added together | Your own log | Your real charging total for the period |
Four Things a Session Figure Is Good For
- What a charge cost. Multiply the session kWh by the price on your own bill: 30 kWh at an example tariff of €0.30 per kWh costs €9.00 — an example, not an average; your bill supplies the real one.
- A session that ended early. A car that usually takes about 35 kWh overnight and one morning shows 9 kWh has told you something stopped the charge — a tripped breaker, a timer, a connector not fully seated.
- Comparing settings honestly. The same top-up at 16 A and at 32 A uses near enough the same energy; only the duration changes. The app record proves it for your own car.
- A simple log for a shared car. Weekly session totals show what the car actually uses — the starting point for splitting household costs or reimbursing a driver, as an agreed estimate.

The Honest Limit: Tracking, Not Billing
No metering certification is stated for this charger, so treat its kWh as an estimate for tracking — accurate enough to run a household log, spot a failed session and check a bill’s plausibility. If money has to change hands on the number itself — billing a tenant, a guest or a customer for exact energy — that is a certified meter’s job; discuss metering with your installer or adviser when you set it up.
The EV-ACS3210E as Your Session Log
The EVDANCE EV-ACS3210E is a 32 A Type 2 portable charger: single-phase at about 7 kW, current adjustable from 10 A to 32 A, with app control and energy monitoring, OCPP-ready, and a 7.5 m cable. The monitoring is the feature this method runs on: the session record turns “charging costs about this much” into a number you read off after the fact.
Frequently Asked Questions
Why does the app show more kWh than my car says it received?
Charging losses. The app counts energy as it leaves the wall; the car counts what reached the battery after conversion. Your bill is written on the wall figure, which is why the app number is the right one for cost.
Can I bill a tenant or guest from the app’s kWh figure?
Not as a metered bill: no metering certification is stated for this charger, so the figure is an estimate. Hosts and households commonly use it for agreed, informal splits — anything that must stand as an exact charge needs a certified meter.
Does a lower current setting make a session use fewer kWh?
No. The battery needs the energy it needs; the setting changes how long delivery takes.
