Peak avoidance mode
Charging at high speeds (high current) can impose significant costs on the user due to the capacity tariff. A user charging at the highest current (32A) for one quarter-hour increases his monthly capacity tariff to 7.4 kW in a single-phase system and up to 22 kW in a 3-phase system.
This mode optimises the charging speed of the car to charge the car as quickly as possible without significantly increasing the month peak.
A peak avoidance mode will be most noticeable because the average grid off-take will always be located around the current month peak. This takes the current home load, solar production and battery into consideration. FlexiO will modulate the EV charger to compensate for this, but with sudden large changes in solar production or home load the month peak can still increase.
In the in this example, the month peak is 5.000 W, and you can see that the grid power averages 5.000 W over the entire charging period; therefore, the month peak is not increased and the car is charged as quickly as possible.
