eSolutions Annex ePro Wallbox
INTRODUCTION
Dynamic Power Management (DPM) is a smart function that allows you to recharge
your electric vehicle using only the power available at home, modulating the
charging power and avoiding unpleasant blackouts. If you are using other
appliances during the charging session, the system can modulate the charging
power towards the car, even suspending temporarily the charging session. As
soon as the other domestic appliances are switched off, the session will
resume at maximum power.
Load unbalance detection, is a specific function for power management.
According to relevant standards for specific countries, the current unbalance
among the phases must not differ by more than a fixed value (different for
each country). This function avoids single phase on board chargers to
withdrawn from the grid an unbalanced current higher than prescribed by local
regulation.
Do not try to install the Power Meter if you are not qualified as a professional electrician. Such behavior can cause serious danger and harm to you and to the people, things or animals around you.
The wall box can work without Dynamic Power Management.
In this case, the installation of a dedicated Power Meter is not necessary,
but avoidance of blackouts is not guaranteed.
