Improved Error Handling
As of software version 1.009.128.0, all errors had been treated in the same way and had
been limited to max. five occurrences. After the fifth occurrence, charging was stopped
permanently and the wall box had to be rebooted again.
One error will be treated differently now, other errors can now be selectively cleared by
unplugging the EV. With the most common errors it is no longer necessary to reboot the wall
The errors are now differently classified
· Permanent internal errors (up to max. five times during one charging session) can
only be cleared by rebooting the wall box. Those errors will be signaled to the EV with
· Errors because of erroneous function of the vehicle or charging chord, e.g.
interlocking error, short circuit at pilot signal, reaction of EV, etc. can be cleared by
unplugging of the charging chord and will be signaled to the EV with +12V.
· Warnings because of erroneous function of the EV will not be limited and are signaled
Authorization – Stopping a Charging Session at the Wall Box
A present charging session can now be stopped with the very same RFID tag with which the
session was initiated. The same function applies to key switch versions of the wall box.
Authorization – Extension of max. RFID tags to up to 20
The new firmware version enables to teach up to 20 RFID Tags.
Authorization – …remains even if errors occur
The improved error handling enables the wall box to monitor the presence of an EV. It can be
ensured that no other EV has been connected since the error, thus the authorization and
consequently the charging session can be kept alive even if errors occur.
