Our 7.4 kW Dual AC charger is a type of electric vehicle (EV) charger that provides an alternating current (AC) output of 7.4 kilowatts and can charge two vehicles simultaneously, making it ideal for locations with multiple EVs needing to be charged at once, such as commercial sites, parking facilities, or multi-vehicle households.
Key Features:
- Power Output:
- The charger delivers 7.4 kW of AC power per vehicle, which is a commonly used charging power for home and public charging stations. It typically offers a good balance between charging speed and cost for non-commercial EV owners.
- Dual Charging:
- The “dual” aspect refers to the charger’s ability to charge two EVs simultaneously. This is ideal for settings where multiple electric vehicles are frequently parked and need to be charged, such as fleet operations or places with high EV traffic.
- Charging Speed:
- A 7.4 kW charger will generally charge an EV battery at a rate of around 30-40 kilometers per hour of charging, depending on the vehicle’s battery size and efficiency. The charging time to fully charge a vehicle depends on the battery’s capacity, but it typically takes about 4-6 hours to fully charge an EV with an average-sized battery (around 30-60 kWh).
- AC Charging:
- Since it’s an AC charger, the power provided by the charger is alternating current, which the vehicle’s onboard charger converts into direct current (DC) to charge the vehicle’s battery. The vehicle must be equipped with an onboard AC charger to handle the power conversion.
- Connector Types:
- The charger will typically use the Type 2 connector, which is the most common standard for AC charging in Europe. In other regions, the connector type may vary, but Type 2 is widely adopted for AC charging across many EV models.
- The dual charger will have two Type 2 charging cables for the two vehicles, allowing both to charge simultaneously.
- Single-Phase or Three-Phase Power:
- In most cases, a 7.4 kW charger operates on a single-phase power supply, which is the standard for home use and certain public charging locations. For three-phase systems, 7.4 kW may be achieved by utilizing a lower amperage. This makes it ideal for home installations without the need for complex electrical infrastructure.
- Installation:
- Installation of a 7.4 kW Dual AC charger generally requires access to a single-phase (or optionally three-phase) electrical supply. It’s suitable for both residential and commercial environments but may require an electrician to ensure the system is set up correctly and safely, particularly when charging two vehicles at once.
Benefits:
- Dual Charging: The ability to charge two EVs simultaneously saves time, space, and energy, making it a practical solution for areas with multiple electric vehicles, such as apartment complexes, workplaces, or commercial fleets.
- Cost-Effective: 7.4 kW chargers are more affordable compared to higher-output chargers like 22 kW or DC fast chargers, making them a good middle-ground option for homes and businesses that need reasonably quick charging without the need for more expensive equipment.
- Faster Than Standard Home Chargers: Standard home chargers typically provide 3.7 kW, so a 7.4 kW charger will charge an EV at double the speed, making it a great choice for faster home charging without upgrading to high-power infrastructure.
- Convenient for Multi-Vehicle Households: For households or businesses with multiple EVs, having a dual charger means they can charge two vehicles at once without the need for additional charging stations.
Considerations:
- Vehicle Compatibility: The vehicle must have an onboard charger capable of handling up to 7.4 kW of AC power. Most modern EVs are compatible, but it’s always good to check the specifications of your EV before installation.
- Installation Requirements: A 7.4 kW charger typically requires a dedicated circuit, and depending on the local grid infrastructure, you may need to install a higher capacity electrical supply, especially for dual charging. Professional installation is often recommended to ensure proper setup.
- Shared Charging Power: In dual chargers, the power may be shared between the two vehicles. If one car is charging and the other is not, the full 7.4 kW may be available to the active vehicle. However, if both vehicles are charging, the power output will often be divided (e.g., 3.7 kW per vehicle), so charging may take longer when both vehicles are plugged in.
Applications:
- Homes: Ideal for multi-EV households where two electric vehicles need to be charged overnight or during the day.
- Commercial Use: Suitable for office buildings, retail outlets, or parking garages with a higher number of electric vehicle users. It can help accommodate a small fleet of EVs without the need for multiple charging points.
- Fleet Charging: Great for fleet operators with multiple EVs, as it allows charging of two vehicles at once, optimizing the charging process.
Overall, our 7.4 kW Dual AC charger offers a practical, efficient, and relatively affordable solution for charging multiple electric vehicles in residential, commercial, or fleet settings.
