Frequently Asked Question

The fundamental difference between AC and DC charging systems lies in where the energy conversion takes place.

AC Charging
Energy conversion is performed by the onboard charging unit (OBC) inside the vehicle.
It has a more economical infrastructure.
It is more advantageous in terms of battery health.
It is generally in the 7.4 kW – 22 kW range.

DC Charging
Energy conversion takes place inside the charger.
Provides much faster charging.
Includes high-power electronics.
Used in commercial fast charging stations.

No. AC charging is one of the healthiest charging methods for the battery.

This is because the energy conversion takes place through the control systems within the vehicle, and the battery operates under lower stress.

AC charging is especially recommended for overnight charging, daily use, and long-term battery health.

Yes. The device only draws the maximum power it supports.

Example:

22 kW device + 11 kW vehicle → 11 kW charging
22 kW device + 7.4 kW vehicle → 7.4 kW charging
Therefore, 22 kW devices are compatible with all AC vehicles.

Compatible with all electric vehicles with Type 2 (IEC 62196-2) socket standard.

Examples of vehicle brands:

TOGG
Tesla
BMW
Mercedes-Benz
BYD
Renault
Peugeot
Hyundai
Kia
Porsche
Other Type 2 supported electric vehicles

Some vehicles have 22 kW AC OBC.

Example models:

Renault Zoe
TOGG T10X
BYD Atto 3
Some versions of Nissan Ariya
Some commercial electric vehicle models
Many vehicles are limited to 7.4 kW or 11 kW.

A 22 kW OBC is a larger, heavier, and more expensive system.

Therefore, many manufacturers prefer the 11 kW level in their vehicles.

Charging time depends on the following criteria:

Battery capacity
Vehicle OBC power
Network infrastructure
Temperature conditions
For example, a vehicle with a 66 kWh battery and a 22 kW OBC can be charged in approximately 3 hours.

Yes. An AC 22 kW charging station can be used at home.

However, a three-phase electrical infrastructure is recommended. If a single-phase infrastructure exists, this should be reported to the manufacturer. The device should be purchased and used as a single-phase device.

Note: Three-phase and single-phase devices are different.

A professional site survey should be conducted.
The electrical installation must be suitable.

The installation infrastructure varies depending on whether the device is three-phase or single-phase.

Recommended Three-Phase Infrastructure

• 3 Phase / 400V AC
• 40A fuse
• 40A residual current device
• 5x6 mm² copper cable
• Strong grounding line

Recommended Single-Phase Infrastructure

• 1 Phase / 220V AC
• 20A or 25A fuse
• 25A residual current device
• 3x6 mm² copper cable
• Strong grounding line

Grounding is essential for safety in electric vehicle charging systems.

• It provides protection against electrical leaks.
• It ensures user safety.
• It is one of the fundamental requirements of IEC standards.

If there is no grounding, the device will not start the charging process for safety reasons.

The recommended grounding voltage is ≤ 5 Ω.

In some sensitive systems, a leakage potential difference below 2.5V is targeted.

Installation costs depend on the following factors:

• Cable spacing
• Electrical infrastructure
• Panel condition
• Construction work
• Protective equipment

In Turkey, typical AC 22 kW installations, excluding appliances but including infrastructure, generally have mid-to-high-end electrical installation costs.

A site survey is recommended for an exact price.

The main standards are:

• IEC EN 61851-1
• IEC 62196-2
• IEC 60364-7-722

The devices are designed according to international safety criteria within the scope of Electrical Engineering.

Yes. Leakage current protection is required.

Recommended protection:

• Type A RCCB 300 mA

Surge protectors are especially recommended for outdoor installations.

SPDs protect the device against the following risks:

• Lightning strikes
• Sudden voltage surges
• Mains voltage fluctuations

OCPP (Open Charge Point Protocol) is the communication protocol between the charger and the central management software.

This allows the management of the following operations:

• Remote control
• User management
• Mobile application
• Energy management
• Reporting
• Roaming
• Payment systems

The following OCPP versions are supported in modern systems:

• OCPP 1.6 J
• OCPP 2.0.1

Next-generation systems can utilize Plug & Charge, advanced cybersecurity, and intelligent energy management features.

Advanced models are compatible.

Yes. Device management can be done via the mobile application.

Actions that can be performed with the mobile application:

• Starting charging
• Stopping charging
• Energy monitoring
• Viewing history
• User management
• RFID identification
• Remote control

The charging process is initiated with the following steps:

1. The cable is connected to the vehicle and the charging station.
2. The device verifies the connection.
3. The device displays a turquoise color when connected to the cable and a blue color when connected to the vehicle.
4. Authorization is performed via RFID or mobile application.
5. The RFID card is brought close to the symbol on the front of the device, and beeps are heard.
6. The vehicle sends a charging request, and charging begins.
7. The device's diffuser color changes to a green heartbeat.

Possible reasons for charging not starting include:

• The cable is not properly seated.
• The RFID tag is not identified.
• The vehicle's OBC system is disabled.
• The vehicle is in fault mode.
• The cable capacity is insufficient.
• There is a grounding fault.

A fast red signal may be seen on the device in case of a grounding fault.

In this situation, there is communication between the vehicle and the device, but the vehicle is not sending a charging request.

Possible causes:

• Vehicle lock
• OBC sleep mode
• Cable problem
• Vehicle software
• Door being open in some vehicles
• Door not being locked in some vehicles

The motor-lock system locks the cable for safety reasons.

In this case, the following steps can be applied:

1. First, push the plug firmly into the device.
2. Turn off the fuse and try to pull the plug out.
3. If it still doesn't come out, push the plug into the device again.
4. Turn on the power.
5. Start charging the vehicle and finish charging with the circuit board.
6. When you see the diffuser turn fuchsia, you can safely remove the plug.

In some cases, a pinch may occur due to cable tension, mechanical pressure, or premature pulling.

In modern charging stations, LED colors provide information about the device status.

• Turquoise: Cable connected to the station.
• Dark blue: Vehicle and device are communicating.
• Green: Charging has started.
• Yellow: Charging paused or battery full.
• Fuchsia: Charging terminated.
• Red: Malfunction.

A rapidly flashing red light usually indicates a grounding fault or high earth resistance.

A slow red flash usually indicates a missing phase connection or phase loss.

Yes. Periodic maintenance is recommended.

Recommended maintenance procedures:

• Annual electrical check
• Connection tightness check
• Software update
• Insulation check
• Leakage current test

Important considerations during device cleaning:

• Pressurized water should not be used.
• Solvents and chemicals should not be applied.
• Microfiber cloths should be preferred.

The device should not be used in the following situations:

• If the cable is damaged
• If the connector is wet
• If there is frost
• If there is a burning smell
• If excessive heat is felt
