What is that?
The Rosenberger connector ist eine Multifunktionsverbindung, die bei den 48-V-Modellen verwendet wird. Sie ist magnetisch und daher leicht lös- und verbindbar sowie im Fahrbetrieb schlüssig. Sie wird eingesetzt beim:
- Charger plug
- der Ladebuchse am Unterrohr oben
- dem Akkusockel
- dem Wicket Cable (im Akkufach)
It establishes the following communication links:
- +/− 48-V-Ladepole
- +/- 12 V from the charger to the battery and from the battery to the stromer
- CAN-Bus, Low und High
PIN assignment Plug
Es gibt verschiedene Rosenbergerstecker die sich vor allem in dee Distanz der +/− PIN’s unterscheiden.
PIN assignment acoustic socket / charging socket
If you measure the voltage at the 12 V pins of the Rosenberger connector with the battery removed, you will get a reading of approximately 10 V. This is normal.
Spare parts
The Rosenberger connector and the charging socket in the battery are not available as spare parts from Stromer.
DIY solution
As an alternative, you can get a Wicket Cable (Stromer Art. No. 402336) buy and repurpose it as a charging plug. A possible supplier for the Rosenberger Connectors and Sockets is, for example, Mouser Electronics.
Charging port
The charging port socket on the Stromer down tube (top) is available as a spare partStromer Art. No. 401409).
Charging base battery
The charging port on the BQ batteries is not available separately. However, it should be identical to the charging port.
Contact problems / corrosion
In combination with current flow and moisture, the plug connection tends to corrode and form verdigris. Due to its magnetic properties, it also attracts even the smallest metal particles. These properties can lead to leakage currents or short circuits. The connections must be kept clean.
Clean the contacts/socket with a lint-free cloth or compressed air.
Do not use contact sprays, greases, or the «all-purpose weapon,» WD-40 Multi-Use Smart Straw.
For corrosion on the socket or charging connector, use isopropyl alcohol and a fiberglass brush for cleaning.
If a pin is defective, the socket or the connector must be replaced. The pins on the charging connector and the battery compartment socket are spring-loaded and can be easily and irreversibly damaged by mechanical tools – caution is therefore advised.
If the battery base in the battery compartment is corroded at the bottom, you may need to clean the Removing the battery compartment. When reinstalling, make sure that the base is not "pulled at an angle" by the connecting wicket cable.
