- Control module 18 main module
- the secondary module 20 module
- step 72 a case distinction is made depending on whether one or more newer firmware updates are available or not. If no newer updates are available, the method ends at end point 74. If at least one newer update is available, the method continues with step 76.
- step 76 associated compatibility data records are called up for the available firmware updates.
- the central control module 18 sends corresponding requests to the server 48 via the external interface 44 and receives the transmitted compatibility data sets.
- the compatibility data records can also be received directly in step 62 together with the data record about the available firmware versions.
- Figures 9a-c show examples of compatibility data sets.
- 9a-b show a respective compatibility data record 78, 80 for the firmware updates for the secondary modules 22, 24 available according to the table in FIG. 7a (version “12.6” for “module 2" and version "1.26” for "module 3") .
- 9c shows one
- Compatibility data record 82 for the further firmware update for the secondary module 22 (version “12.7” for “module 2”), which will be available later according to the table in FIG. 7b.
- the compatibility data records 78, 80 and 82 for the firmware updates of the individual modules are shown in FIGS. 9a-c as a table, the other modules of the charging station 2 in the left column and the associated ones in the right column
- the compatibility of the firmware updates available for the individual modules with the current and available firmware versions of the other modules is checked on the basis of the compatibility data records received.
- Step 88 the firmware updates to be installed are selected on the basis of the previously carried out check.
- the firmware updates that are compatible with the current firmware versions or the remaining firmware updates to be installed for the other modules are selected, so that a set of mutually compatible firmware versions results
- the method ends in end point 92 if no firmware updates have been selected for installation. Otherwise, the selected firmware updates are received by the server 48 in the next step 94.
- the central control module 18 sends corresponding requests via the external interface 44 and receives the firmware updates sent by the server 48.
- the firmware updates received are loaded onto the corresponding modules in step 96.
- the central control module 18 transmits the firmware update for a secondary module via the corresponding one
- Communication link (e.g. communication link 26 for the
- Secondary module 20 to the respective secondary module, so that the firmware update is loaded onto the firmware memory of the corresponding secondary module.
- the central control module initiates a restart of the respective secondary modules in step 98 by issuing a corresponding instruction via the associated one
