The i-CHARGE car charging stations made by Schrack Technik blaze the trail for climate-friendly mobility. Easy operation combined with intelligent charging logic means effortless, fast and safe charging. Regular software updates and remote maintenance ensure that the installation works reliably and that its safety is always up to standards.
Charging stations from the i-CHARGE Series are the best solution for all electrically powered vehicles currently available (cars, motorcycles, scooters and bicycles) and designed to fit all locations:
To be able to charge the vehicle battery the alternating current (AC) from the power grid is converted to direct current (DC). The conversion is made by the charger, which is either built into the vehicle (on-board) or into the electric charging station. An electronic control system in the vehicle (battery management system, BMS) monitors the charging progress, the cell temperature and the voltage of the power cells. It adjusts the charging process accordingly to optimise charging time and battery life. Power is fed from special power plugs and charging cables, which not only transfer electricity but also data.
Compared to e-cars, power supply requirements are less demanding in case of single-track vehicles, such as e-bikes or e-scooters. Their batteries need lower charging power due to their lower capacity. Therefore, a correctly fused earthed socket is sufficient.
E-vehicles are chiefly charged while at home or at the office. Therefore, estimating an average distance travelled in Austria of about 34 km per day, electric cars are suitable for about 80 % of the population.
Thanks to DC rapid charging stations, where inverter and charger are built into the charging station, electric vehicles can be used for long-haul journeys:
Recharging up to 80 % is possible in less than 30 minutes (depending on the capacity of the vehicle battery and the available charging power - assumption 60 kWh battery with 150 kW charging power).
Charging times vary depending on battery capacity, charger and available mains power. On average, the charging time from "empty" to fully charged for a 60 kWh battery is between 2 hours (mode 3) and 24 hours (earthed socket, mode 1). DC rapid charging (Mode 4 and 50 kW) can be completed within one hour.
HPC chargers (High Power Charger) with a charging power of up to 350 kW, shorten the charging time accordingly. The actual charging times are usually shorter, because the battery is hardly ever completely empty.
i-CHARGE Charging Stations for use in public and semi-public areas can be equipped with different activation and payment systems. Activation can be done by key, RFID card or app. Customers can pay using a coin slot, QR code and direct payment by credit card or settlement via OCPP (via the power utility company or a payment service provider). The charging stations can also be integrated into a parking garage system.
Metering of the amount of electricity used for charging at the charging point is done by fitting them with an MID approved meter. To allow for future even regulations regarding calibration, all i-CHARGE CION Online products are equipped with a meter viewing window.
The standardised communication protocol, OCPP 1.5 or 1.6, allows using products from different manufacturers within a shared charging network. The protocol authorises the charging cards of the clients and, after charging has finished, transfers so-called charging data records (CDR), which contain the charging time and electricity amount. The operator of the charging station can then invoice the charging to the customer. It is also possible for several operators to practice clearing, so that their clients can use the stations of other operators (roaming).
A green light on the CION charging station signals that the charging station is in standby mode. The station automatically detects when a cable is connected. If activation is required, the key switch or a contactless card (RFID) can be used to activate the charge. If no activation is required, charging is activated automatically. During this process, the LED display changes to a green flashing mode. If the authentication has been accepted, charging starts and the LED indicator changes to blue.
The battery management system (BMS) of the vehicle controls the charging process and ensures fast charging and optimised battery life. Pulling out the plug on the vehicle side ends the charging. The charging socket or the charging cable immediately disconnect from the power supply, which reliably prevents any personal injury.
This process is similar with other models. However, the signal colours may vary!
Charging stations with a Schuko or CEE socket have an integrated auxiliary contact. This contact recognises a plugged-in plug and ensures safe switching on and off. A combined current breaker with residual current tripping (RCBO) protects the charging point. The electric vehicle is either connected directly (Mode 1) or with a mobile charger (called "in cable control box", ICCB) (Mode 2).
In contrast to Mode 1 and 2, the charge controller and the entire safety equipment are located in the charging station. The charging cables do not have any additional protection or communication equipment. Typical charging powers are between 3.7 kW single-phase to 43 kW three-phase. The manufacturers of vehicles and charging stations in the EU have agreed on the TYPE 2 charging plug system. In addition to the TYPE 2 socket, a fixed TYPE 2 charging cable can also be used. The charger is located in the vehicle and determines the maximum possible charging power.
Im Gegensatz zu den AC-Ladeverfahren Mode 1 bis Mode 3 fließt bei CHAdeMO und CCS Gleichstrom von der Ladestation in die Fahrzeugbatterie. Das Ladegerät befindet sich in der Ladestation – deshalb sind Größe und Gewicht nicht durch die Platzverhältnisse im Fahrzeug beschränkt. Die Ladeleistung ist wesentlich höher und ermöglicht eine schnelle und sichere Ladung der Fahrzeugbatterie. Abhängig von der Ladeleistung und der Batteriekapazität kann die Batterie in ca. 8 - 30 Minuten auf mindestens 80 % geladen werden.
