Dynamic load balancing ensures that you can make optimal use of the maximum load capacity of the charger, within the available capacity in the home. It prevents the fuses from blowing. This works as follows.
The charger takes into account the energy consumption in the house. When you switch on a device with a high consumption, and the car is charging at that time, the charger reduces it’s consumption. This way the house capacity is not overloaded. If you switch the device off again, the charger will increase its charge speed.
Dynamic load balancing is possible when the charger supports this and a sensor is placed to report the consumption.
An alternative is to secure the charger at a lower power. This reduces the charging speed.
