If charging does not start properly, the most common errors are as follows:
- Other consumption in the installation is too high
- Minimum current is too low
- Rotated from measurement device to charging box
Other consumption in the installation is too high
As a partner, you can see this if you go to power meters under the menu item "power meters". 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 look at whether the customer has high consumption in general and possibly suggest upgrading the main fuse.
As an end user, you can ask your partner to have access to view the graphs from your power meter and see the consumption of your site.
Minimum current is too low
All cars have a minimum current they can charge at. This differs between car models. If the load balancing is set to a lower limit than the car can handle, the charging will not be able to start.
Rotated from measurement device to charging box
It is common that something has been rotated either in the plant or during installation. You can troubleshoot this by disabling the load balancing and then go into the charging box and set 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, if a different phase rises than the one on which charging takes place, it is rotated somewhere.
Then check that the incoming L1, L2, L3 matches the incoming L1, L2, L3 in the charging box.
Also check that the current transformers for the current meter are on the correct phase and that they are correctly placed in the terminal block.
