How does the charger's load balancing work?
When several charging robots are connected on the same circuit, all available energy will be dynamically divided between the units.
The total load will therefore never exceed the limit set during the installation. For load balancing against the main fuse, you can add an Equalizer to the installation.
Depending on which product variant you are using, you can connect up to 3 Easee Home chargers to the circuit. Alternately, you can scale the infrastructure for larger sites using Easee Charge.
All connected cars can be charged simultaneously and the available charge current is automatically shared between them, provided that there is enough power available on the circuit. If there is not enough power available, the cars will be put in the queue.
For all cars to charge simultaneously we recommend:
- 25 chargers for a 63A fuse on a 400V TN-system
- 15 chargers on a 63A fuse on a 230V IT/TT-system.
Load balancing occurs through proprietary wireless technology, which does not require any additional infrastructure, cloud-connection or even the Internet.
Local WiFi is not required but it is recommended. This will increase stability and functionality.
More technical information is available at Installing the Equalizer.
Can my car charge on 3 phase?
It depends on the type of car you have and the type of electric grid you are on.
- If you are connected to a TN-system (400V), many EVs will be able to charge with 3-phase.
- If you are connected to a IT-system (230V) it may be limited by what car models you have.
Contact your car dealer for full information regarding your specific car.
We always recommend asking the electrician to select a 3-phase cable when installing your Easee charger whenever possible. This will make sure your installation is future-proofed.
If you have an IT-system
There are not many cars that support conventional 3-phase charging on IT-systems. For this reason, the charger is set to not allow 3-phase charging under 11 A when wired to an IT-system.
That means if your fuse is 10 A, or your Equalizer is limiting the available power to the charger, the charger will only offer 1-phase charging. (The minimum amperage for 1-phase charging is 6 A.) Not all cars can be charged with 3-phase on an IT system, so please check with your car dealer before changing phase mode.
If your car is limited to 1-phase charging on IT, you can lock the charger for 1-phase in the phase mode settings. If nothing is specified, we recommend setting Phase mode to Automatic inside the Easee App. On Automatic, most cars will be able to communicate with the charger about which phase to use.
This function needs to be activated manually. The factory default setting is single-phase once an IT-grid is detected.
Can I decide which phase to use if I have an Equalizer?
When using the Equalizer, the charger will use the least loaded phase. If the limit for one phase is exceeded the charger will automatically change to the least loaded phase.
