At its top setting of 32 A on a single-phase supply, the EV-ACS3210E delivers about 7 kW. A 40 kWh battery therefore needs roughly six and a half hours from empty to full, a 60 kWh battery about nine and a half, and the everyday 20–80% top-up of a 60 kWh pack around five and a half to six hours, with about a tenth allowed for losses. The limit is not the 32 A — it is the single phase.
Key Takeaways
- At 32 A single phase, the EV-ACS3210E delivers about 7 kW: roughly 6.5 hours for a 40 kWh battery, 9.5 for 60 kWh, losses allowed for.
- 22 kW at 32 A needs three phases. This is a single-phase charger, and the car’s onboard charger can lower the pace further.
- Lower settings stretch a session in proportion; they exist to fit the circuit, not to save energy.
- An overnight session returns about 50 kWh — several days of driving for most households.
Why 32 A Single Phase Is About 7 kW, Not 22 kW
Power is voltage multiplied by current, on each phase the charger uses. A single-phase supply at 230 V and 32 A multiplies out to 7.36 kW at the wall, and EVDANCE lists this charger at about 7 kW single-phase — the honest planning figure. The 22 kW that clings to “32 A” in adverts comes from three-phase supplies: the same 32 A carried on three phases instead of one. This charger is single-phase by design, so one phase is all it draws on. Our explainer on single-phase vs three-phase charging sets the three classes side by side.
The second limit sits in the car. Its onboard charger converts the AC to DC, and if it accepts less than 7 kW, it sets the pace and every time below stretches.
Charging Times at the 32 A Setting
Worked examples at about 7 kW, with roughly 10% allowed for losses and the slower top end of a charge — the same convention as our guide to charging time at 7 kW, 11 kW and 22 kW.
| Battery size | Empty to full | 20% to 80% |
|---|---|---|
| 40 kWh | About 6.5 hours | About 4 hours |
| 60 kWh | About 9.5 hours | About 5.5–6 hours |
| 80 kWh | About 12.5 hours | About 7.5 hours |
In range terms, the U.S. DOT puts Level 2 charging at 10–20 miles of range per hour, and a 7 kW unit sits in that band: one overnight session returns several days of ordinary driving for most households.
What Stretches or Shortens a Session
- A lower setting, chosen on purpose. The current adjusts from 10 A to 32 A. At 16 A the unit delivers roughly half the power, so the same energy takes roughly twice as long.
- A car that accepts less than 7 kW AC. Its onboard charger is the ceiling, whatever the wall unit offers.
- The top of the battery. Charging tapers near full, so the last fifth takes disproportionately long — why 20–80% is the everyday window.
- A cold battery. A cold pack accepts charge more slowly until it warms, and winter sessions run long.
The EV-ACS3210E at Its Top Setting
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, app control with energy monitoring, OCPP-ready, and a 7.5 m cable. Run at 32 A on a supply that supports it, it is an overnight charger in the plain sense. If your home has a three-phase supply and a big battery regularly needs filling faster, that is a different class of tool — the EV-ACS3205PE is the 22 kW three-phase portable in this range.
Frequently Asked Questions
Is 7 kW fast enough for overnight charging?
For most households, yes. Eight hours at about 7 kW returns roughly 50 kWh to the battery — several days of typical driving. It is only tight if you arrive near empty and need a full, large battery by morning, every day.
Why does my car show a longer time than the table?
Usually because its onboard charger accepts less than 7 kW, the unit is set below 32 A, the battery is cold, or the session runs to 100%, where charging tapers. The table assumes the car takes everything the charger offers.
Would a 32 A three-phase charger charge my car three times as fast?
Only if the supply is three-phase and the car accepts 22 kW AC. With either missing, the session falls back to the weakest link — a single-phase car on a three-phase charger charges at single-phase speed.
