The go-eCharger PRO is a stationary charging station for public and semi-public parking areas. The charger is designed for use in multistorey car parks and residential buildings, but is also suitable for public and private use.
During development, the emphasis was placed on ease of maintenance and user convenience, as well as a comprehensive range of performance features, with even the basic version being equipped with a premium scope of services. The included highlights are e. g. charging capacity of up to 22 kW, load balancing, several data interfaces, backend software and OCCP.
Type 2 socket
The highlight of the PRO version is the modular design, which allows the charging unit to be simply plugged and secured onto the pre-installed wall unit. This saves time and costs during maintenance.
In addition, the charging box can be equipped with a calibrated meter, 5.5 inch touch display and permanently fixed cable. A standard built-in ultrasonic sensor monitors the parking area and can send information via the standard OCPP.
The Charger PRO is universally applicable for all electric car models approved on the European market.
All electric vehicles in Europe are equipped with the type 2 plug (also called Mennekes plug). Older models, which are still provided with the type 1, can as well be charged by using type 1 to type 2 adapters or cables.
Type 2 forms the basis for CCS (Combined Charging System). The plug, also known as Combo Type 2, is the same as the Type 2, but with two additional contacts for fast DC charging.
The Charger PRO is also available with a permanently installed charging cable. Everything is tidy: the socket serves to store the plug and the cable can be wound around the wall box.
With the Charger a high charging capacity of up to 22 kW can be achieved.
The desired charging power is freely selectable via the app or the button on the box. The charge can be regulated in 1 ampere steps (from 6 to 32 amperes. There are 32 LED’s on the LED-ring of the Charger, each one corresponding to 1 ampere).
With IP54 protection, the Charger is splash-proof and can withstand heavy rainfall.
The IP (International Protection) defines the protection of electrical equipment for different environmental conditions. For example, the ingress of foreign bodies (such as dust) and water.
The high-performance plastic ASA used for our Chargers is extremely break-proof even under extreme weather conditions (hail, heat, cold).
The plastic used is also light-resistant, so the colour is retained for many years (does not fade/yellow).
The wall installation box is installed by an electrician. The charging box can then be attached to the wall installation box by any operator.
This makes it easy to change the charging box (e.g. for service purposes) in a matter of seconds without specialist knowledge.
The quick-change system is also a good idea for use at several residences, as the charging box can simply be carried along and used at the respective location (a second wall installation box is required for this).
Our Charger is optionally available with high resolution 5″ display for detailed information or without display. The screen is easy to read even in sunlight.
The basic setting of the box can be configured via display. In addition, the user receives various charging information. Charging rates and access information can be displayed in the business area. The display can be adjusted in general. For example, advertisements can be placed in best quality.
On the one hand, RFID is used for billing purposes. RFID is used for authorization and identification. This allows billing to take place. With the help of OCPP, a billing system is established with backend services (providers of billing services such as “has to be”).
On the other hand, RFID is used for authorization. For example, for access control in shared car parks (residential building).
In addition, each charging box offers the possibility of creating and managing accounts. This enables you to authorise, check, evaluate and export access to loads as a CSV file in private as well as business environments.
An RFID chip is included in delivery.
In order to offer maximum flexibility, suitable interfaces are built in for all common application areas. LAN/WLAN is standard and therefore of course integrated. GSM always offers the option when no data exchange is possible on the other interfaces.
Used for monitoring the chargers in the entire parking garage or parking area. Different zones can be regulated. All go-eChargers can be controlled universally to optimize the charging process.
In the future (with several e-vehicles per household) it will become increasingly important for charging stations to have load balancing. When charging several vehicles at the same time, normal builing and parking garage connections are overloaded.
go-eChargers avoid that problem with the load balancing function that allows them to communicate together and if available with the go-eController, which will monitor the building load. This ensures efficient and safe power distribution between a nearly unlimited amount of chargers.
When used in multi-storey car parks, load balancing is also suitable for assigning priorities (parking space prioritisation: classification/categorisation of parking spaces that load quickly or less quickly).
Cost-effective charging when the price of electricity is lowest. This is possible with our partner aWATTar. The go-eCharger can dial into the electricity price exchange and see 24 hours in advance how high the electricity price will be the next day.
This ensures efficient and ecological use of electricity-surplus, and therefore contributes to reducing the impact we humans have on our environment. On the same time, it allows you to reduce your electricity bill.
Prerequisite to benefit economically: The end consumer must be an aWATTar customer.
Economically and ecologically elegant: Via Timer it is possible to define the start time for charging. This is optimal, for example, for charging at night or in the early hours of the morning (savings potential through night tariffs).
But this function also pays off in environmental terms, similarly to the Double-Eco function. By not charging at peak times, voltage peaks can be reduced and the excess current can be used at night.
The loading capacity for each RFID card can be read via different accounts. Other settings for personalization can also be made. For example, which colors the LEDs of the charger should have. Whether brighter or more colourful – just as you like it. The locking variants of the box can also be defined individually.
The go-eCharger PRO can communicate with other smart devices/systems in the network and is individually adaptable. For example, Language assistants such as Alexa from Amazon or Siri from Apple, can be used soon.
The network capability also enables communication with the inverter of a photovoltaic system.
The charger can use OCPP to communicate with backend services (providers of billing services such as “has to be”). The main purpose of this function is for billing or error transmission.
OCPP = Open Charge Point Protocol.
OCPP function is only available at an extra charge.
Installing updates is an essential benefit of chargers connected to the Internet. The go-eCharger does not have to be sent to the service because of the update capability. Updates are easy via our app.
OCPP also plays an important role for this application. This allows the setting, that an update is installed at a certain time (e.g. outside operating hours, during the night).
Of course, the go-eCharger PRO has a non-verified electricity meter. This is always necessary for billing electricity.
Currently a calibrated meter according to German calibration law is being worked on. It is to be expected that this will be available at the end of 2019.
The calibrated electricity meter makes it possible to bill electricity in all countries (e.g. Germany). In addition, the customer can obtain information/measurement results on charging processes carried out in the past at a later date (i.e. they can be read off the PRO Box).
The calibrated electricity meter is only available at an extra charge.
The FI protects against electric shocks. To ensure that the RCD installed in the house continues to provide reliable protection even when the charging box is used, an additional RCD for DC faults (type B) must be installed in the charging box or building.
The RCD is particularly important when vehicles generate residual current. Should a fault current occur, the FI switches off the box and thus ensures the highest possible level of safety.
With the go-eCharger you get a system with an open interface (API). This is especially interesting if you want to connect your own applications. For example a photovoltaic system. The open interface ensures that other manufacturers can combine their devices with the go-eCharger.
The go-eCharger can specifically use surplus current from a photovoltaic installation via API (an open software interface) or the go-eController*.
With the go-eController*, photovoltaic overproduction can be used not only for the go-eCharger, but also for other smart devices such as hot water boilers.
But even without the go-eController*, the go-eCharger can communicate with the photovoltaic system using API, if an inverter is available. The well documented API of the charging box for communication between the charging box and the photovoltaic inverter can be downloaded here.
