| Rated AC output | Up to 22 kW, commonly supplied by a three-phase 400 V AC circuit at 32 A per phase. Using the three-phase power formula, √3 × 400 V × 32 A is approximately 22.2 kW. | Confirm the local grid voltage, available phases, current capacity, and whether the charger can be configured for the installation. |
| Single-phase supply | At 230 V and 32 A, single-phase input provides about 7.4 kW, not 22 kW. | A 22 kW unit connected to a single-phase supply will deliver less power if it supports that connection; check its wiring and configuration requirements. |
| Vehicle charging limit | The vehicle’s onboard AC charger sets the maximum AC charging rate. A vehicle limited to 11 kW AC will not charge at 22 kW from a 22 kW AC unit. | Check the vehicle specifications for its AC charging limit, supported phase count, and connector type. |
| Illustrative charging time | For a vehicle accepting 22 kW AC, a 60 kWh battery would take about 2.7 hours at the ideal rated power. Actual time is longer due to charging losses, vehicle limits, and charging behaviour. | Estimate time using the energy to be added and the vehicle’s actual charging rate; do not assume the charger’s rating is always achieved. |
| Charging-time estimate | Approximate time (hours) = energy added (kWh) ÷ effective charging power (kW). For example, adding 40 kWh at an effective 11 kW takes about 3.6 hours before allowing for variations and losses. | Use the energy required to reach the target state of charge, not necessarily the battery’s full capacity. |
| Connector compatibility | Connector and inlet requirements vary by market and vehicle. Type 2 is commonly used for AC charging in Europe; other regions may use different standards. | Verify the connector standard, cable or socket arrangement, and vehicle compatibility for the destination country. |
| Electrical installation | A 22 kW installation typically requires a suitable three-phase circuit, correctly sized conductors and protective devices, and installation in accordance with local electrical regulations. | Have a qualified local electrician assess the supply, cable run, earthing, protection, and any required permits before installation. |
| Electrical protection | Required residual-current and overcurrent protection depends on the charger design and local rules. Some units include DC residual-current detection; installation requirements still vary. | Check the product documentation and applicable local code to determine the correct external protection and installation method. |
| Standards and market fit | AC conductive charging equipment is covered by IEC 61851 requirements, alongside relevant regional electrical and product-safety rules. | Confirm applicable certifications, documentation, operating conditions, and compliance requirements for the country of installation. |
| Load management | Dynamic load management can adjust charging current to help keep total site demand within a configured limit, where the equipment and system support it. | Consider available grid capacity, other large electrical loads, and whether load management is needed at the property. |
| Best-fit use case | A 22 kW AC charger can suit locations with three-phase power and vehicles capable of accepting high-power AC charging, such as some homes, workplaces, and fleet sites. | Compare the vehicle’s AC limit and the site’s electrical supply before choosing a 22 kW rating; a lower-rated unit may be more appropriate where either is limiting. |
