Hi friends, just wana know the charging cable we got with atto 3 is 7kw or 22kw? Someone said to me that If i installed 3 phase swith then with this cable takes around 6 to 8 hours for full charge otherwise with single phase it shows more than 17 hours for full charge ?

Thanks in advance

Slowest charging possible

NOT supported for phase 3

Others with home charging experience will give better answers

The atto3 will take at most 7kw on a type 2 cable, it is a limitation of the AC to DC onboard charger in the car. You can charge at about 80kw on the CCS2 DC connector though..
If you have 3 phase at home at 32amps a phase and a 3 phase socket you can buy a AC/DC CCS2 charger these are about $6,000 each tho.

Check the manual

The charging cable you get with the Atto3 is 8A 1.5kW single phase 240v.
You can buy a type 2 to type 2 cable for untethered public AC chargers for about $180 which are 7kW rated single phase.
All DC chargers are tethered so no cable required.

Atto3 only supports single phase / 32A / 7.2kW

However, it won't be your last EV, so get the 22kW / 3phase 32A instead.

Don't get the 11kW/3phase-16A cable. This will charge your atto at single phase , 16A, half speed.

Neither. It's about 1.5kW.

Your Atto can accept up to 7kW from a single phase (they can't accept 3 phase).

Best and safest way to charge is get yourself a 7kW wall charge point installed.
If you can't do that (renting etc), then make sure when you use the portable charge unit that it's not on a circuit being shared by other high drain (eg: clothes dryer) or continuous use devices (eg: fridge etc) as you can easily overload the circuit.
