Yes, the connection between the charge point and the grid is indeed balanced. Therefore, 3-phase EV chargers typically have balanced loads.  However, a 3-phase connection does not eliminate the possibility of overloading. To ensure this, you may need to install a Dynamic Power Management (DPM) module. This means that the electrical power in your home is distributed evenly among the three phases, preventing overloading and damage to the electrical system. This is important to ensure that the charger works properly and to avoid potential safety hazards. More information about DPM can be found here.
