If you are planning a home EV charger installation in Al Waab, one of the first decisions is usually:

Should I install a 7 kW, 11 kW or 22 kW charger?

The answer is not simply “choose the biggest charger.”

The correct charger depends on:

• Your electric vehicle

• The vehicle’s maximum AC charging capacity

• Single-phase or three-phase electrical supply

• Available electrical load

• Distribution board capacity

• Charger specifications

• Daily driving distance

• How long the vehicle normally remains parked

• Cable route between the DB and parking area

• Current KAHRAMAA requirements

A 22 kW charger may look more attractive on paper, but if your vehicle can accept only 11 kW AC, installing a 22 kW wallbox will not make that vehicle charge at 22 kW.

For many homeowners, a properly selected 7 kW or 11 kW home charger may already provide enough overnight charging.

Quick Comparison: 7 kW vs 11 kW vs 22 kW

*These are simplified nominal figures. Actual charging speed can be lower because of the vehicle’s onboard charger limit, battery conditions, charger settings, electrical supply, temperature and charging losses.

The most important rule is:

Your actual charging speed is limited by the weakest part of the charging system.

For example, if you install a 22 kW wallbox but your vehicle’s onboard AC charger accepts a maximum of 11 kW, your vehicle will normally charge at no more than approximately 11 kW AC.

Before Comparing Charger Sizes, Check Your Vehicle First

The first question should not be:

“How powerful is the charger?”

It should be:

“How much AC charging power can my vehicle accept?”

Different EV models have different onboard AC charging limits.

Depending on the vehicle, its AC charging capability may be approximately:

• 3.6 kW

• 7 kW / 7.4 kW

• 11 kW

• 22 kW

• Another manufacturer-specified rating

Therefore, before purchasing or installing a charger, confirm:

• Vehicle make

• Vehicle model

• Model year

• Charging connector

• Maximum AC charging rate

• Single-phase or three-phase AC charging capability

The vehicle manual or manufacturer’s technical specifications should provide this information.

What Is a 7 kW Home EV Charger?

A charger commonly described as 7 kW or 7.4 kW is a popular option for residential charging.

It is often suitable for drivers who park their EV at home overnight.

For example, if a vehicle stays parked for 8 hours, a 7 kW charger can theoretically deliver a substantial amount of energy during that period, although real-world charging will vary.

A 7 kW Charger May Be Suitable If:

• Your vehicle accepts approximately 7 kW AC

• Your property has an appropriate electrical supply

• You normally charge overnight

• Daily driving distance is moderate

• You do not need very rapid home charging

• Available electrical capacity does not justify a larger charger

For many residential users, 7 kW can provide a practical balance between charging speed and electrical-load requirements.

Advantages of a 7 kW Charger

Potential advantages include:

Lower Electrical Demand

It normally places less demand on the property’s electrical system than an 11 kW or 22 kW charger.

Suitable for Overnight Charging

If the car remains parked for several hours every night, maximum charging speed may not be necessary.

May Require Less Electrical Modification

Depending on the existing installation, a lower-power charger may be easier to accommodate.

However, a site assessment is still required.

Compatible with Many EVs

Many electric vehicles support AC charging around this level.

Limitations of a 7 kW Charger

A 7 kW charger may not be ideal when:

• The EV has a large battery

• The vehicle regularly returns home with a very low battery

• Several long trips are made every day

• Faster turnaround between journeys is required

• The customer owns an EV capable of substantially faster AC charging and wants to use that capability

In such cases, an 11 kW charger may be worth considering if the property and vehicle support it.

What Is an 11 kW Home EV Charger?

An 11 kW AC wallbox normally requires a suitable three-phase electrical supply.

It can provide noticeably faster charging than a 7 kW unit when the vehicle is capable of accepting 11 kW AC.

An 11 kW Charger May Be Suitable If:

• Your vehicle supports 11 kW AC charging

• Three-phase power is available

• The property has sufficient spare electrical capacity

• The distribution board can accommodate the required circuit

• You regularly drive longer distances

• You want faster home charging than approximately 7 kW

• The installation complies with current requirements

For some modern EVs, 11 kW is a very practical home-charging level because the vehicle itself may already be limited to 11 kW AC.

Why 11 kW Can Be a Good Middle Option

An 11 kW charger sits between standard overnight charging and higher-capacity 22 kW charging.

It can be attractive because it offers:

• Faster charging than 7 kW

• Lower electrical demand than 22 kW

• Good compatibility with many three-phase-capable EVs

• Practical overnight charging for larger batteries

However, installing an 11 kW charger only makes sense when the vehicle, property supply and electrical system all support it.

What Is a 22 kW Home EV Charger?

A 22 kW AC charger is a higher-capacity residential charging option.

KAHRAMAA’s updated procedures state that residential buildings are limited to AC chargers with a maximum capacity of 22 kW, subject to the applicable approval and installation requirements.

But this does not mean that every villa should install a 22 kW charger.

Nor does it mean every property has enough electrical capacity for one.

When Does a 22 kW Charger Make Sense?

A 22 kW charger may be worth considering when:

• The EV genuinely supports 22 kW AC charging

• Suitable three-phase supply is available

• The property has sufficient electrical capacity

• The distribution board can accommodate the required dedicated circuit

• Higher home charging speed is genuinely useful

• The installation meets current KAHRAMAA requirements

If your vehicle accepts only 11 kW AC, a 22 kW wallbox may still operate with it, depending on charger compatibility, but the car will normally limit charging to its own maximum AC rate.

Therefore:

22 kW wallbox ≠ automatically 22 kW charging.

Is 22 kW Always Better Than 11 kW?

No.

Suppose:

Charger: 22 kW
Vehicle onboard AC charger: 11 kW

The vehicle cannot simply accept 22 kW because the wallbox can provide it.

In that situation, you may pay for:

• Higher-capacity charger

• Larger electrical infrastructure

• Potentially heavier cable requirements

• Higher circuit capacity

• Additional electrical modifications

without receiving faster charging for that particular vehicle.

This is why vehicle specifications should be confirmed before the charger is purchased.

Simple Charging-Time Example

Consider an EV that needs approximately 40 kWh added to its battery.

Ignoring charging losses and vehicle limitations, the theoretical comparison would be approximately:

However, these figures are only theoretical examples.

Actual charging may take longer because of:

• Vehicle onboard charging limit

• Battery-management system

• Battery temperature

• State of charge

• Charger settings

• Electrical supply

• Charging losses

• Vehicle charging curve

The example is useful for understanding the difference between charger ratings, but it should not be used as a guaranteed charging time.

The Question Most Homeowners Should Ask

Instead of asking:

“What is the fastest charger I can buy?”

A better question is:

“What charging capacity do I actually need for my daily driving?”

For example, a customer who:

• Drives moderate distances each day

• Returns home in the evening

• Parks for 8–10 hours

• Charges regularly overnight

may not need the highest possible charging rate.

A properly designed 7 kW installation may be completely adequate.

Another customer who:

• Drives long distances

• Has limited charging time

• Owns an EV supporting 11 kW AC

• Has suitable three-phase capacity

may benefit from an 11 kW charger.

A 22 kW charger becomes more relevant when both the vehicle and property can actually make use of it.

Step 1: Confirm the Vehicle Connector

Before EV charger installation in Al Waab, confirm the vehicle’s charging connector.

The charger plug and vehicle inlet must be compatible.

Do not select a wallbox based only on:

• Price

• Advertised kW rating

• Appearance

• Mobile application features

Vehicle compatibility comes first.

Send Electrician Doha:

• Vehicle make and model

• Vehicle model year

• Photo of charging port if required

• Charger brand/model

• Charger datasheet or rating label

This allows us to better understand the proposed installation before the site assessment.

Step 2: Confirm Single-Phase or Three-Phase Supply

The available electrical supply significantly affects charger selection.

A site inspection should confirm whether the property has:

• Single-phase supply

• Three-phase supply

• Appropriate main electrical capacity

• Suitable distribution-board arrangement

An 11 kW or 22 kW charger should not be promised simply because three-phase wiring is visible somewhere in the property.

The actual supply and available capacity must be assessed.

Step 3: Assess Available Electrical Load

An EV charger is a significant electrical load that may operate continuously for several hours.

Before installation, the electrician should assess the property electrical system.

This can include:

• Main incoming supply

• Main breaker

• Existing connected loads

• Air-conditioning loads

• Water heaters

• Cooking equipment

• Other high-load equipment

• Available DB capacity

• Phase distribution

• Proposed charger rating

A spare breaker space does not automatically mean the property has enough electrical capacity for a 22 kW charger.

Electrical load and circuit capacity must both be considered.

Step 4: Inspect the Distribution Board

The distribution board is an important part of the EV charger assessment.

The technician may need to inspect:

• DB condition

• Breaker arrangement

• Available space

• Incoming supply

• Earthing arrangement

• Existing cable condition

• Phase arrangement

• Proposed EV circuit connection

• Signs of previous overheating or modifications

If the existing DB is not suitable, additional electrical work may be required before installing the charger.

Step 5: Inspect the Parking Location

Choosing the wallbox position is also important.

The technician should check:

• Where the vehicle is normally parked

• Vehicle charging-port location

• Available wall or mounting surface

• Distance to the distribution board

• Exposure to outdoor conditions

• Potential vehicle impact

• Pedestrian pathways

• Cable reach

• Accessibility for future servicing

The charging cable should reach the vehicle comfortably without becoming a regular trip hazard.

Step 6: Measure and Plan the Cable Route

Cable distance can significantly affect the installation.

Possible routes include:

• Surface conduit

• Electrical trunking

• Ceiling/service areas

• External walls

• Existing service routes

• Underground routes where appropriate

The electrician needs to consider:

• Total distance

• Installation method

• Ambient conditions

• Protection from physical damage

• Cable capacity

• Voltage drop

• Wall penetrations

• Required finishing

A 5-metre installation and a 50-metre installation should not be treated as the same job.

Step 7: Plan a Dedicated EV Charging Circuit

A fixed home wallbox should be planned as a dedicated electrical load.

The installation may require:

• Dedicated electrical cable

• Suitable circuit breaker

• Appropriate isolation

• Required electrical protection

• Earthing

• Cable containment

• Outdoor-rated accessories where necessary

• Circuit identification and labels

The exact protective arrangement should be selected based on:

• Charger specifications

• Manufacturer requirements

• Electrical system

• Current electrical regulations

• Current KAHRAMAA requirements

KAHRAMAA’s technical specifications require EV installations to comply with the latest applicable Electricity Wiring Code and relevant electrical standards.

Current KAHRAMAA Requirements Are Important

This is particularly important for homeowners planning an EV charger now.

KAHRAMAA announced updated EV-charger installation procedures on 28 October 2025.

According to that update:

• Prior approval is required.

• Installation must follow KAHRAMAA’s official procedure.

• Applications are to be submitted through a certified electrical contractor.

• Residential properties are limited to AC chargers up to 22 kW.

• Charging devices are required to connect to KAHRAMAA’s smart platform after installation.

• The property owner remains responsible for charger operation and maintenance.

Therefore, the approval pathway and latest requirements should be confirmed before installation begins.

Do not assume that a charger can be purchased and installed immediately simply because the property has enough electrical capacity.

7 kW vs 11 kW vs 22 kW: Which Would We Normally Consider?

Choose Around 7 kW When:

• The vehicle supports around this charging rate

• Overnight charging is sufficient

• Daily mileage is moderate

• A suitable electrical arrangement is available

• Higher charging capacity is unnecessary

Consider 11 kW When:

• The vehicle supports 11 kW AC

• Three-phase supply is available

• Property capacity is sufficient

• Faster home charging would be useful

Consider 22 kW When:

• The vehicle supports high-rate AC charging

• The property can support the electrical load

• Suitable three-phase infrastructure exists

• Faster AC charging genuinely provides a benefit

• The proposed installation meets current requirements

What If I May Buy Another EV Later?

Future vehicle plans can influence charger selection.

For example, your current car may accept only 7 kW AC, but you may expect to purchase another EV later that supports 11 kW.

In that situation, it can be sensible to discuss future requirements during the initial site survey.

Possible considerations include:

• Charger capacity

• Cable route

• Circuit design

• Distribution-board capacity

• Load management

• Future second EV

• Future second charger

However, installing oversized infrastructure “just in case” is not always the most economical solution.

The decision should balance present needs, realistic future plans and site capacity.

What About Two Electric Cars?

If a household expects to charge two EVs, the installation requires additional planning.

Questions include:

• Will both vehicles charge simultaneously?

• What are their AC charging limits?

• Is there enough property capacity?

• Would load management be required?

• Will there be one charger or two?

• How are the parking spaces arranged?

• Can both cable routes be installed cleanly?

Two 22 kW chargers should never simply be assumed to require or receive 44 kW simultaneously.

The complete electrical system and charging strategy need to be designed appropriately.

Smart Chargers and Load Management

Some EV chargers provide smart functions such as:

• Adjustable charging current

• Charging schedules

• Mobile application control

• Usage monitoring

• User access control

• Dynamic load management

• Solar integration on compatible systems

These features may be useful, but they should not distract from the basic electrical requirements.

The priority order should remain:

1. Vehicle compatibility

2. Electrical capacity

3. Safe circuit design

4. Current regulatory requirements

5. Appropriate installation

6. Then smart features

A charger with an advanced mobile application is not automatically the right charger for the property.

Common Mistakes When Buying a Home EV Charger

Mistake 1: Buying 22 kW Because It Is the Biggest

A 22 kW charger provides little charging-speed benefit if your vehicle accepts only 7 or 11 kW AC.

Mistake 2: Buying the Charger Before Checking the Property

The existing electrical supply may not support the selected charger rating without modification.

Mistake 3: Ignoring the Vehicle’s Onboard Charger

The car—not just the wallbox—determines the maximum AC charging rate.

Mistake 4: Ignoring Cable Distance

A long route between the DB and parking space can significantly change the installation requirements.

Mistake 5: Assuming a Spare DB Space Means Capacity Is Available

Physical breaker space and available electrical load are different things.

Mistake 6: Selecting the Charger Without Checking Current Approval Requirements

KAHRAMAA’s updated procedures require approval before EV charger installation.

Frequently Asked Questions

Is a 22 kW EV charger allowed at a home in Qatar?

KAHRAMAA’s October 2025 updated procedure permits residential AC chargers up to a maximum of 22 kW, subject to prior approval and the applicable installation requirements.

Is 22 kW better than 11 kW?

Not necessarily. If your vehicle supports only 11 kW AC charging, a 22 kW wallbox will not make that vehicle charge at 22 kW.

Is 7 kW enough for home charging?

For many drivers who charge overnight, 7 kW can be sufficient. The decision depends on battery size, daily driving, parking duration and vehicle charging capability.

Does an 11 kW charger require three-phase electricity?

11 kW residential AC charging is normally associated with a suitable three-phase supply. The actual property supply and charger requirements should be checked before installation.

Does a 22 kW charger need three-phase supply?

22 kW AC wallboxes normally rely on a suitable three-phase electrical arrangement. The specific charger and property supply must be confirmed.

Can I install a 22 kW wallbox for a car that charges at 7 kW?

It may be technically compatible in some cases, but the vehicle will still limit its AC charging rate. Buying a larger wallbox therefore does not automatically provide faster charging.

Can you tell me which charger to buy?

We can review the vehicle specifications, charger rating and site conditions before recommending an appropriate installation approach. The final choice should also consider manufacturer specifications and current regulatory requirements.

Can you install a charger that I have already purchased?

The charger should first be checked for its connector, rating, specifications and suitability for the vehicle, property and applicable requirements.

Can you give the final price from photos?

Photos can help with an initial assessment. A final quotation may require site measurement, DB inspection, load assessment and confirmation of the proposed installation route.

Which Charger Should You Choose for Your Al Waab Home?

There is no single charger size that is best for every EV owner.

For many properties:

7 kW offers practical overnight home charging.

11 kW can provide a useful speed increase when both the car and property support three-phase charging.

22 kW is appropriate only where the vehicle, electrical capacity, supply and current requirements allow the additional charging capability to be used effectively.

The best approach is therefore:

Vehicle → Property → Electrical Load → Charger → Installation

—not simply buying the largest wallbox first.
