The main differences between AC and DC charger station?
DC charger station
- faster (50 kW and more), bigger and very expensive
- from 20% to 80% capacity in 1h, from 80% to 100% capacity could take another 1h (because of overheating protection of battery, current is decreased)
AC charger station
- smaller dimension, slower
DC chargers should be located along the highways. For residential / commercial / office locations AC chargers should be installed.
|AC Charger station||DC charger station|
|Maximum charging power||3.6 kW – 22 kW||up to 150 кВт|
|Phases||1-phase or 3-phases||–|
|Limitation||Electric vehicle chargers have different limitations||Different standards
CCS, CHAdeMO, Tesla
|Время заряда (50 кВт)||5 – 20 hrs||1 – 1,5 hrs|
The availability of fast-charging stations in Ukraine have been improved, which is good news for long-distance drivers. However, the problem is still the insufficient number of public charging stations in cities. In particular, look at housing estates where residents do not have own their garages. But also public car parks, areas in front of shopping centers, restaurants, school facilities, and so on.
LUMiCHARGER – AC charger station – 22 kW
Charging stations are available from many vendors, but the main obstacle is non-existence of suitale power cabling. This can be added (if local transformer capacity allows), but the cities are reluctant to dig through the roads and pavements. SEAK can use the existing public lighting network and integrate these public charging stations into omnipresent lamps. The citizens will be able to charge their cars at the place where it is parked (work, housing …).

Power control for Charging Station
Integration with public lighting SEAK SMART CITY
EV chargers mounted on lamp poles communicate with SEAK SMART CITY lighting control system to negotiate the power available for EV charging. During the day, street lighting remains in standby mode and we use full line capacity for EV charging. At night, part of the capacity is used for lighting, the rest for cars. Intelligent dimming of luminaires (in times and places where no 100% intensity is required all night) increases even more the maximum power we can deliver to vehicles.
Day: Luminaires at 0%
Night: Luminaires at 80%
Charging conditions and payment
Electricity for EV charging is very cheap compared to petrol: the price of electricity for 100 km is about 2 EUR. Therefore, charging is often provided free of charge (as support for the development of clean transport). However, it is not sustainable for massive deployment and car charging should be paid. We work with multiple payment gateways, which work in similar way for user
The driver first unlocks the charger by using the mobile application by scanning the QR code, touching the RFID card or sending SMS.
Operator of payment gateway will issue an invoice for the used electricity to individual users and collect the payments (typically via credit card).
The city receives the payment from the gateway operator and is therefore not loaded with any additional administration.
We can integrate the system with existing EV charging payment systems and local chip card systems
Connection charging station to electric vehicle
Type 2 connector (Mennekes) is most used in European countries an it has three pins for three phases and two control pin. LUMiCHARGER has Type 2 connector (Mennekes).
This standard designed dor charging station for electric vehicles to charge alternating current through both 3 phases (Tesla) and 1 phase (Nissan LEAf, Hunday KONA)
January 2013 IEC 62196 Type 2 connector was chosen by European Commission as an official charger for European Union. Since then, it has been adopted as the recommended connector in some countries outside Europe.
