Common problems with charging stations are:
- Locked cable
- Charging session that can’t be ended
- Connection lost
All possible problems are described in the manual of the manufacturer.
We offer first line support 24/7 to EV-drivers and owners of a charging station that is connected to the back office of E-Flux. Every charging station that is connected to the E-Flux back office has a sticker with our helpdesk’s phone number. If we cannot solve the problem from distance, then it is probably a hard ware issue. In this case we will contact the installation company through our ticketing system. If needed, the manufacturer will be involved by exchanging the charging station.
If the connection of the Ethernet cable or sim card is blinking green, then the charging station is properly connected to the back office of E-Flux. When you login to the maintenance platform you can search for the charging station number. If the connector status shows “available”, then the charging station is communicating with the back office.
If you are an installer of charging stations we are happy to cooperate with you. Please contact us by sending is an e-mail or giving us a call.
In order to export data a connection must be made between the charging station and the backoffice. This can be a GPRS or an Ethernet connection. At locations with limited reach we advise to use an Ethernet cable. Please take into account that when changing the firewall the connection between E-Flux backoffice and the charging station has to be renewed.
When choosing the right charging station you have to check:
- The power connection (1-phase of 3-phase)
- Diameter of the cable which runs from the fuse box to the charging station.
- Type of car and battery capacity. Charge capacity determines how fast a car can charge.
- Location: for public locations we advise a heavy duty charging station with IK10 grade.
- Limited power available: if this is the case a smart charging grid will be ideal.
With load balancing the available power is divided under the EV’s that are charging. Most Load Balancing systems detect how much power is required to charge the car and how much power there is left in the electricity network. Static load balancing means that every charging car gets the same amount of power delivered. In a Dynamic load balancing situation, the system checks how much power there is left. Other appliances like a heat pump, washing machine, fridge etc. use electricity and therefore limited the available power. An external energy manager measures how much power there is left, and this will be communicated to the E-Flux Management Platform through an API connection. Based on this information, the charging stations will be limited in their power. We call this a Smart Charging Grid. This is ideal for companies and apartment buildings.
A master stations has more functionalities than a slave, and it can connect to a backoffice system. In a master/slave installation only one master is connected to the backoffice, and the other slaves can be online thanks to an Ethernet connection with the master station. This structure can save costs, because a Master station is more expensive. It can be a good solution for a parking lot where you want to put a group of chargers.
AC stands for alternating current. In Europe we use AC for household appliances, and because we have access to a 3-phase electricity network we can use this to charge electric vehicles. On most locations we can use 32A (22kW) or 63A (43kW) power to charge. As long as both the charging stations and the car can handle this power, a battery of 20kW (average EV) can be charged for 80% within 25 minutes.
DC stands for Direct Current. A DC charger requires a transformer to transfer AC to DC current. This involves a lot of power (125A) and is therefore a high cost installation. Because the transformer in the car does not have to transfer the power, it is possible to charge a car faster than with AC current. There are over 600 fast chargers in the Netherlands.
Installed charging stations can only be connected to the E-Flux management platform when they fit the requirements.
Please contact us when you want to connect a charging station. We will provide you with an installation kit that consists a manual, sim card and mobility card. Do you want to connect a charging station of a brand that is not in this list? Please contact us.
Contact us and we will look into your request. First we have to check if the charging station has all the functionalities that are needed to connect to our platform. Please notice that we only can connect our back office system to charging station with OCPP communication.
Charging stations that have the OCPP functionality can be connected to the back office of E-Flux. See an overview of the brands we already have a connection with.
E-Flux doesn’t sell the hardware product. We cooperate with different wholesalers and manufacturers that offer charging stations. This overview shows what brands can be connected to E-Flux.
CPO is short for Charge Point Operator, the organization that is responsible for the management of charging stations. This is different than the owner of a charging station, because the Operator runs the management platform that connect all the charging stations. Also support, payment traffic, invoicing and interoperability are proceedings of an Operator.
A Mobility Service Provider (MSP), provides mobility cards that can be used for charging electric vehicles. With an RFID chip the card makes connection with the charging station. E-Flux is both CPO and MSP.
The IK classification of a product indicates how strong the housing is. By means of a test, the effect of an impact is measured, such as with a hammer. The lowest class is 0, the product is not protected against an impact. The highest class is IK-10, where the casing can withstand a blow of front object with a weight of 5kg at 40cm distance. IK-10 is a requirement for charging stations at public locations. Most charging stations have IK-8 or IK-10.
The IP class indicates how well a housing holds back dust and liquids such as water:
IP 21 drip-proof
IP 22 Touch-safe
IP 23 Rainproof
IP 44 splash-proof
IP 54 Dust-free / splash-proof
IP 55 Dust-free / spray-proof
IP 65 Dust-free / spray water-tight with water from different directions
IP 67 Dust proof / Waterproof

The Smart Charging functionality of E-Flux is applied in a Smart Grid. In addition to dynamic load balancing (external hardware solution), the vehicles are loaded to priority. Our intelligent software ensures that all cars are fully charged during the specified time frame, provided that enough electricity is available. The driver indicates in the E-Flux app when he leaves, which car he has and what the battery status is. On this basis, electric cars are loaded to priority. The customer has the option to set flexibility discounts. The longer the EV driver remains, the cheaper it will be charging per hour.
OCPP is short for Open Charge Point Protocol. A communication protocol specialy designed for charging stations of electric vehicles. Implementing this protocol into charging stations makes it possible to register and handle payments of charging sessions. Charging Stations that can connect to the OCPP protocol are suitable for a connection with E-Flux.
