About 7 hours from empty to full. The EV-ACT5006T delivers up to 11.5 kW when hard-wired at 48 A, so a 75 kWh battery needs about 7 to 7.5 hours once losses and the slower top end are counted. The session most drivers actually run, 10% to 80%, takes about 5 hours. On the plug-in version, which runs at 40 A, add about an hour to each of those figures.
Key Takeaways
- A 75 kWh battery charges from empty to full in about 7 to 7.5 hours on the hard-wired ACT5006T at 48 A.
- The everyday 10–80% top-up takes about 5 hours hard-wired, or about 6 hours on the 40 A plug-in setup.
- Losses, tapering near full, a cold battery and the car’s onboard charger all stretch the simple division.
- Both configurations fit normal overnight charging; only a full charge on the plug-in setup can outlast the night.
The Numbers for a 75 kWh Battery
Charging time is the energy you add divided by the power you add it at. A 75 kWh battery rarely needs all 75 kWh: drivers top up a window, not the whole pack. The table works the common windows for both ways this charger can be installed, with figures that already allow roughly 10% for losses and tapering near full.
| Charge window | Energy added | Hard-wired, 48 A (11.5 kW) | Plug-in, 40 A (9.6 kW) |
|---|---|---|---|
| 0–100% (full) | 75 kWh | About 7–7.5 hours | About 8.5 hours |
| 10–80% | 52.5 kWh | About 5 hours | About 6 hours |
| 20–80% | 45 kWh | About 4–4.5 hours | About 5 hours |
| One hour plugged in | — | About 10 kWh added | About 8.5 kWh added |
Our general guide to charging time at 7 kW, 11 kW and 22 kW works the same arithmetic for other battery sizes and power levels.
Why the Simple Division Is Only the Starting Point
Dividing 75 by 11.5 assumes the car takes full power from the first minute to the last. Three things stretch the real session:
- Losses. Roughly a tenth of the energy drawn becomes heat in the conversion, so the wall supplies more than the battery stores.
- The top end slows down. Every EV tapers its charging rate as the battery approaches full, so the last 20% takes disproportionately long — why the 10–80% window is so much quicker than a full charge.
- The car can be the limit. The car’s onboard charger converts AC power. If it accepts less than 11.5 kW, it sets the pace and the session runs longer than the table.
Cold weather stretches times further, because a cold pack accepts charge more slowly until it warms. Our explainer on how many kWh it takes to charge an EV covers the energy side of the same sum.
Which ACT5006T Setup You Have Changes the Answer
The EV-ACT5006T is one charger with two installation configurations, and they charge at different rates:
- Hard-wired on a 60 A circuit: the full 48 A, up to 11.5 kW. This is the setup behind the faster column in the table.
- Plugged into a NEMA 14-50 receptacle: the circuit is a 50 A circuit, and continuous charging on it is limited to 40 A, giving 9.6 kW. Same charger, about a fifth longer per session.
Both use the same 7.6 m NACS cable and IP65/IP66 rating; the full specification is on the EV-ACT5006T product page. Which configuration suits your circuit is a decision for you and your electrician before installation.
What This Means Overnight
For a 75 kWh car, the practical question is rarely the full-charge figure. A typical day’s driving needs a fraction of the pack, and even a 10–80% session finishes in about 5 hours hard-wired or 6 hours plugged in — comfortably inside a night. A true empty-to-full charge fits an 8-hour night on the hard-wired setup; on the plug-in setup it is the one session that can run past it. Pairing the session with off-peak hours matters more than the last half hour of speed, as our guide to smart charging and time-of-use tariffs explains.
Frequently Asked Questions
Why does my car show a longer time than 7 hours?
Usually because the car’s onboard charger accepts less than 11.5 kW of AC power, or the battery is cold, or the session runs to 100% where charging tapers. The charger offers up to 11.5 kW; the car decides how much of it to take.
How long would a 60 kWh battery take on the same charger?
By the same arithmetic, about 5.5 to 6 hours from empty to full hard-wired, and about 4 hours for a 10–80% top-up.
Does the plug-in version charge too slowly for daily use?
No. The difference is about an hour on a large top-up and minutes on a typical daily one. The plug-in setup only becomes the constraint if you regularly need a near-full 75 kWh battery by morning.
