Single-phase AC charging for sites where electrical capacity limits higher output.
7 kW AC charging is used where a single-phase supply defines the upper limit of available power. Most installations operate close to the capacity of a standard single-phase circuit.
The charger supplies AC power, while the vehicle’s onboard charger handles the conversion to DC. Charging power is determined by the vehicle’s onboard charger, not by the AC charger alone.
This AC charging system is used in residential and small commercial projects where single-phase power supply and long parking duration define charging feasibility.
Operates on AC 220V single-phase supply, matching common residential and small-site electrical conditions.
Uses a single charging outlet, reducing wiring complexity and on-site installation work.
Provides energy measurement for operational records and basic billing.
Delivers up to 32A AC output, aligned with typical vehicle onboard charger limits at this power level.
Applied in locations where vehicles remain parked for extended periods, such as overnight or full-day stays.
Introduces limited additional load to existing distribution systems, reducing upgrade pressure.

7kW systems apply where vehicles remain parked for extended periods.
They are common in residential and workplace environments with limited electrical capacity.
7kW AC charging is selected when site electrical capacity is the primary constraint, rather than charging speed. The focus is on how many charging points the site can support under the same power supply. At this level, more units can be deployed without major grid upgrades.
Vehicles remain parked for several hours or overnight.
Single-phase power is shared with other electrical loads。
Several chargers run under the same power capacity.
Existing sites used without major electrical upgrades.
Used when three-phase supply is available and moderate charging turnover is required.
Used when higher per-vehicle output is needed within shorter parking duration.
Used when charging time constraints exceed what AC systems can provide.
The following questions address key concerns when evaluating 7kW AC chargers for commercial projects.
7kW works best when vehicles remain connected for several hours. Charging time depends on vehicle onboard capability and available circuit capacity.
Yes. Actual charging speed is limited by the vehicle’s onboard charger, not only by the charging station itself.
This depends on the available electrical capacity. In many projects, several units are deployed under shared power distribution.
No. 7kW chargers usually operate on single-phase power, which is common in residential and commercial buildings.
7kW is not designed for high-turnover fast charging. It is mainly used in long-duration parking.
