OBO Ion charging station

Simple. Safe. Considered.

Electro-mobility continues to make progress and revolutionise our world. This applies to vehicles and the associated driving experience, as well as to the charging infrastructure. Our answer: The prewired, ready-for-connection OBO Ion charging station for relaxed, PV-optimised charging of electric vehicles – at home or even for a whole vehicle fleet on a company's site. The impact-resistant housing according to IK08 makes it extremely robust and, with a protection rating of IP66, it can be used in both indoor and protected outdoor areas.

Advantages of the OBO Ion charging station at a glance

Charging according to Mode 3 in accordance with EN IEC 61851-1
Single, dual and triple charging
Charging power can be adjusted dynamically in 1 A steps: 1.4 to 22 kW (factory setting 11 kW)
With a manual switch of the charging power to 11 kW, the charging station can qualify for the KfW subsidy in Germany, for example.
Potential-free enabling contact, e.g. for PV systems: ripple control receiver, timer, RFID module and smart home technology

Modbus RTU protocol via RS-485 interface for bidirectional communication
Permanently installed 5 m charging cable with type 2 connector for all current vehicle types, including cable holder
With Green Zero Switch: 0.0 kW standby consumption
Practical features: Integrated temperature monitoring, DC error current monitoring, status information via LED display

Optional protection against wind and weather: The OBO Ion charging station is intended for indoor areas or protected outdoor areas. A weather protection roof is also available, which provides extra protection and convenience for charging stations in exposed locations.
Available in open or closable versions: It's up to you: The Ion charging station is available with a key or an highly practical pressure switch. In easily accessible car parks, the use of the variant with key switches is recommended. The variant with pressure switch can also be used in private garages or other locations which are reliably protected against unauthorised access.
Optionally with integrated surge protection: For locations with a feed line of more than ten metres in length or without a construction-side surge arrester, OBO can offer a variant of the Ion charging station with integrated type 2 + D1 surge protection for the data cables, in accordance with DIN VDE 0100-443. This means that both the charging point itself and the connected electric vehicle are protected against damage from surge voltages.

Charge electric vehicles sustainably and efficiently

Well-thought-out technology, simple mounting, tailor-made safety: The Ion charging station offers your customers two options for PV-optimised charging.

Static PV excess charging

With this variant, the charging operation of the OBO Ion charging station is controlled by an external unit, which sends an enabling signal from a previously defined PV excess current level. These units include:

Photovoltaic inverter
Ripple control receiver
Timer, key switch / numeric lock / RFID module
Smart home technology

The loading operation switches on automatically on a PV current excess. If there is insufficient PV energy, the charging operation is automatically interrupted. If necessary, a series-connected external switch (e.g. IP44, wall-mounted) allows the switch-over to a charging operation, irrespective of the PV status, at any time.

Example with 10 kW AC solar power system (summer day)

Charging into the car	44	kWh
Pure PV component:	36.025	kWh
Autarchy	81.87	per cent
Charging time	9.25	H
Charging power	5.5	kW

Benefits of static PV excess-current charging

Increase in autarchy by plus 10% to 15%
Financial implementation costs
Refittable in a simple and uncomplicated manner
Compatibility with different inverters/smart meters

Dynamic PV excess-current charging

The Ion charging station can be dynamically activated directly via external Modbus RTU 485 controllers. This means that the following functions can be controlled, amongst others:

PV excess-current charging
Dynamic load management
Digital authentication via web or app

Charging into the car	44	kWh
Pure PV component	41.15	kWh
Autarchy	93.52	per cent
Charging time	8.5	H
Charging power	Up to 9	kW

Benefits of dynamic PV excess-current charging

Maximum autarchy up to plus 30%
Multiple charging programs selectable
Can be used digitally via web or app management
Refittable in a simple and uncomplicated manner
Compatible with various EMS devices

In conjunction with the optional EMS device, the loading operation switches on automatically on a PV current excess and can be adapted in an optimised manner. If there is insufficient PV energy, charging is regulated automatically and interrupted. The programming and setting of the charging times can be carried out individually.

The Ion charging unit variants at a glance

The Ion charging unit is available in four different model variants, meaning that the right charging station can be found for any requirement and any installation environment:

Ion Basic: With pressure switch, without surge protection
Ion Key: With key switch, without surge protection
Ion Basic Protect: With pressure switch and surge protection
Ion Key Protect: With key switch and surge protection

Your Ion charging station is only a click away. We'd like to present the Protect variants to you in more detail, which are only available from OBO:

Here, surge protection is already integrated: The Ion Protect version of the charging station

The VDE 0100-443 standard demands the presence of surge protection. If none exists in the building, at least one type 2 SPD must be erected at the infeed point of the system during the creation of a new circuit. With cable lengths of over ten metres, additional surge protection is recommended on the charging unit, which protects both the charging station and the electric vehicle. Surge protection also applies for the data cable connection between the charging station and, for example, the PV system between the charging station and electric vehicle.

With the Ion charging station, you can meet all these requirements in a simple manner: The Ion Protect version of the charging station has integrated standardised complete surge protection. This is only available from OBO:

To protection current infeed: surge protective device compact module, type 2+3

Surge protection in sub-distributors according to VDE 0100- 443 (IEC 60364- 4- 44)
Arresting capacity up to 60 kA (8/20) in total
Integrated 3+1 solution for TN and TT network systems at 45 mm module width
High-performance varistor systems
