If charging does not start properly, check the most common errors as follows:
Excessive other consumption in the installation
Minimum current is too low
Scheduling
Rotated from measurement device to charging box
Settings
Excessive other consumption in the installation
As a partner you can see this if you go to the power meter under the menu item "power meter". There you can see the consumption graphs for the last 24h and the last 7 days. Take the time of the charging session when the customer experienced problems and see what the consumption was at the time. Also review in general if the customer has high consumption and possibly suggest upgrading the main fuse.
As an end user, you can ask your partner to get access to see the graphs from your power meter and see the consumption in your facility.
Minimum current is too low
All cars have a minimum current they can charge at the lowest point. This differs between car models. If the load balancer is set to a lower limit than the car can handle, charging will not start.
Scheduling
If charging does not start during scheduling, the reason may be as follows:- The charging box loses connectivity and cannot retrieve the scheduling information from the Charge Amps Cloud.
You have a Volvo charging hybrid. Volvo has a problem with their plug-in hybrids not waking up during scheduling.
For older Volvo plug-in hybrids that are Sensus-based, you can schedule in the Volvo on call app.
If it is a Google-based plug-in hybrid, this is unfortunately not possible. You can work around this problem if you have an iPhone with this function. Automate a shortcut to open the Volvo app at certain times of the night to "wake up" the car.
Make sure the socket is set to schedule. The symbol shows a red bell.
Rotated from measurement device to charging box
It is common that something has rotated either in the system or during installation. You can troubleshoot this by deactivating the load balancing and then going to the charging box and setting it to 1-phase. Then start a charge on L1. Then look under the measurement device at the 24h graph and see that the graph for L1 rises in line with the charge. Repeat the procedure for L2 and L3. If the correct graph rises in comparison with the phase you have chosen where charging should take place, everything is correct. However, should a different phase rise than the one where charging takes place, it is rotated somewhere.
Check that incoming L1, L2 and L3 correspond to incoming L1, L2 and L3 in the charging box.
Also check that the current transformers for the current device are on the correct phase and that they are correctly placed in the terminal block.
Settings
Make sure that nothing is ticked that should not be.
Make sure that the socket is "on" and not "off" and that the schedule is off if it should not be activated.
Make sure the RFID lock is not on if it should not be.
If RFID should be enabled and the charging box is load balanced, make sure that RFID is correctly configured in the admin interface. RFID must be linked to a user and a charging station.
