Electrical Requirements
| Charger Type | Power Draw | Circuit Required | Charge Speed | Typical For |
|---|---|---|---|---|
| Single Phase (7kW) | 32 amps @ 240V | Dedicated 40A circuit | 40-50km range per hour | Most Australian homes |
| Single Phase (7.4kW) | 32 amps @ 240V | Dedicated 40A circuit | 45-55km range per hour | Standard installation |
| Three Phase (11kW) | 16 amps @ 415V | Dedicated 3-phase circuit | 65-75km range per hour | Homes with 3-phase supply |
| Three Phase (22kW) | 32 amps @ 415V | Dedicated 3-phase circuit | 120-140km range per hour | Large homes, multiple EVs |
Most EV owners are perfectly served by a 7kW single-phase charger. This adds 40-50km of range per hour — plenty for overnight charging. Three-phase (11-22kW) is only needed if you drive very long distances daily or have multiple EVs.
