As workplaces across the UAE continue to adopt sustainability-led initiatives, the installation of an EV Charger on office premises has quickly become a key priority. With more electric vehicles entering the UAE market – supported by initiatives like Dubai’s Green Charger Programme and the UAE’s long-term Net Zero 2050 vision – businesses are beginning to evaluate the best type of EV charger for their facilities. According to the UAE government’s targets, the country aims to have over 70,000 public and private EV charging points by 2030, reflecting a strong shift toward workplace and destination charging.
Against this backdrop, companies often face one core question:
“Which is better for offices – an AC EV Charger or a DC EV Charger?”
Both charger types play essential roles in the EV ecosystem, but their purpose, capabilities, cost considerations, and operational suitability differ meaningfully. For offices, choosing the right type of charger is not just a technical decision – it impacts employee experience, operational efficiency, long-term sustainability goals, and workplace infrastructure planning.
Understanding AC and DC EV Chargers for Workplace Environments
Before selecting an EV charger, it is crucial to understand how AC and DC systems differ in functionality, speed, cost, compatibility, and installation requirements. Both are essential components of modern EV charging solutions, but their applications vary significantly.
What is an AC EV Charger?
An AC EV Charger provides alternating current to the vehicle, which is then converted into DC power by the EV’s onboard converter. The charging speed depends on the charger’s power rating (most commonly 7 kW or 22 kW) and the capacity of the car’s onboard AC converter. AC charging is the most common, practical, and cost-effective option for workplaces where vehicles are parked for several hours.
Modern commercial AC chargers are often compact in design, durable (IP65 and IK10 rated), and suited for long-term, daily office use. Some models also support dual charging operation (e.g., dual AC chargers), allowing two vehicles to charge simultaneously – ideal for offices with multiple employees driving EVs.
What is a DC EV Charger?
A DC EV Charger supplies direct current directly into the EV’s battery, bypassing the onboard AC converter entirely. Because DC chargers deliver higher power output (ranging from 60kW to 360 kW), they can rapidly charge an EV – sometimes from 20% to 80% in just 15–25 minutes, depending on the vehicle. These chargers are commonly found in public stations, highways, logistics hubs, and high-turnover commercial locations.
DC chargers are built with robust protection standards (IP54, IP55, IK10), advanced cooling systems, and intelligent power modules, making them suitable for heavy-duty environments. Their speed and efficiency make them beneficial for workplaces that require frequent, rapid charging.
Key Differences Between AC and DC Charging for Offices
Before selecting the right charger for an office environment, it’s essential to understand how AC and DC charging differ in terms of speed, infrastructure needs, and overall cost. Each option brings distinct advantages depending on how long employees’ vehicles remain parked and how frequently charging is required.
To help businesses make an informed and efficient choice for workplace charging, here’s a clear table outlining the key differences between AC and DC EV chargers.

|---|---|---|---|
| 1 | Charging Speed | Slow to moderate (3.3–22 kW) | Very fast (60–360 kW+) |
| 2 | Charging Method | AC converted to DC inside the car (uses onboard charger) | AC converted to DC inside the charger itself (bypasses onboard charger) |
| 3 | Ideal Usage | Homes, offices, apartments - daily/overnight charging | Highways, commercial hubs, fleets - rapid top-up charging |
| 4 | Installation Cost | Low to medium | High (needs stronger power infrastructure) |
| 5 | Charger Cost | Affordable, suitable for residential users | Expensive, commercial-grade technology |
| 6 | Power Requirement | Single/three-phase power | High-power grid connection (400–800 V) |
| 7 | Battery Impact | Gentle on battery - recommended for daily use | Faster heat generation - frequent use may reduce long-term battery life |
| 8 | Charging Time | 4–8 hours for full charge | 15–60 minutes depending on battery and kW |
When Should Offices Choose AC EV Chargers?
