EV charging devices and their sensory technology
EV charging devices may require authorisation by RFID or NFC identifier in order to function.
The EV public charging points generally require authorisation in order for the user to be able to start charging up. This authorisation is made by RFID or NFC identifier card or tag. Depending on the location, the card or tag identifier can be ordered in advance (e.g. from "Virtapiste" charging stations) or collected, e.g. from the lobby/info- or cashdesk at a company offering charging services (a fee may be charged).
The devices equipped with sensory technology can give a breakdown of diverse charging data with the aid of the back-end system.
On the basis of the data accumulated, the provider of the charging services is able to monitor e.g. the total monthly consumption of their charging device and if desired, can price their charging services according to the actual electricity consumption.
EV charging by RFID or NFC identification on a Keba charging device
Using a charging device equipped with sensory technology as just as simple as using a charging device that operates without authorisation functions. The devices give clear light and sound signals and/or text notification when the charging starts up successfully.
1. Device is ready for use
There is generally a light on the charging device that indicates the device status. The colour of the light may vary according to the different make of device.
For example, the blue led light in the Keba charging device in this photo flashes every 3 seconds when the device is ready for use, awaiting identification by RFID or NFC sensor.
2. Authorisation of device by sensor
Charging is authorised on the device using an RFID/NFC card or tag. The device may give an audio signal to indicate acceptance of the authorisation, depending on the model.
Some charging devices may require authorisation by sensor card or tag for opening the cover. This serves as authorisation to the charging device at the same time.
The charging cable can be connected to the Keba in this example also before authorisation is given. In this case charging will be initiated only after authorisation.
3. Connect the cable to the charging device
In order to charge up from a public charging point, the EV motorist should have a Type 2 charging cable, with which the car is connected to the encased charging device.
In the case of a Keba charging device, after authorisation the EV motorist has one minute to secure the charging cable to the device and to the car.
4. Connect the cable to the vehicle
When the charging cable is connected to the device, the other end is connected to the car. Charging starts automatically as long as the device has been authorised before the charging cable is connected.
If authorisation has not yet been given, it is possible to do so at this point.
5. Charging is on
The device light indicates the charging status. For example on the Keba device shown here, a green light flashes every 2 seconds during charging .
The colour of the light also varies depending on the device.
6. Charging is complete
When charging has finished, the charging cable should be removed from the car. It is then necessary to wait for the charging cable lock to be released from the charging device (this may take a moment) and the cable is disconnected from the charging device.
Charging devices requiring a sensor card or tag for opening the cover: the cover should be opened by sensor before the cable is disconnected.
