Frequently Asked Questions

You can buy PhaseBox directly in the webshop. If you are a company, you can order against an invoice. In that case, send us an email at contact@phasebox.eu.

If you purchase it without installation, we will send it free of charge. If you order with installation, the installer will bring the charger at the time of installation.

No, shipping is included in the price.

It's possible to route the incoming cable through the rear wall of the charge box. Usually it's possible to find a way to make a nice-looking installation. Talk to your installer and prepare the best way to install.

You either order installation in combiantion with the purchase or you contact a qualified electrician.

PhaseBox is most conveniently mounted on a wall. Incoming mains cable can be routed either from below or from the back.

Yes, we recommend lightning protection. Ask the installer about your electrical system and whether it is relevant to supplement with lightning protection.

Yes, of course. PhaseBox is IP66 rated, which corresponds to dustproof and protection against water jets under high pressure. PhaseBox is also impact resistant to IK10, the highest rating available.

You can read the energy consumption on the meter directly through a window on the side of the charger, which is a unique PhaseBox feature. A standard PhaseBox equipped with an energy meter is possibly the best and most flexible solution for those who have to report energy consumption when charging.

MID, Measuring Instruments Directive, means that the meter is approved for accounting and to debit energy.

You can manage your chargers, and you also have access to an overview of chargers and their charging data. If you have the dynamic power management option activated, you can monitor how the system operates in real-time. You can also set parameters for each charger, such as maximum charging current. You can also manage RFID tags in the portal.

You can decide which of your available tags that should be able to start specific charging boxes. In the chargings overview, you can also follow which charges are associated with a particular RFID tag.

You have access to an overview that show all chargings. You can filter data and download in several formats, such as PDF and Excel.

Using the optional power management system in PhaseBox is a smart way to minimise charging time by using all available power. PhaseBox continuously reads how much power the house consumes by metering incoming mains to the building. PhaseBox updates charging power instructions to the car, considering available power. The power management works together with PhaseBox's function for automatic phase selection.

Dynamic power management is a smart way to not have larger mains fuse than required.

The process is monitored continuously, and maximum charging current instructions are sent to the car at approximately five-second intervals.

A meter that measures phase current is installed at the building's incoming mains connection. Power information is sent over WiFi to PhaseBox.

Yes. If PhaseBox is equipped with both power management and automatic phase selection, measurements from the incoming mains connection will be used for phase selection.

Phase selection is useful if, for example, you have a house with known imbalance between phases. Phase selection is also perfect for multi-family garages or company car parks where charging power must be balanced to match available power.

Phase selection works with all cars and is fully automatic to the user. You can choose which phases you want to use. For example, you might want to use specific phases when charging.

It is possible for PhaseBox to use all combinations of phases for charging. We call this a phase strategy.

You can use any of the following straegies:

Fixed three-phase, all phases are connected to the car.
Autimatic two-phase, the two least loaded phases are connected.
Automatic one-phase, the single least loaded phase is connected.
Fixed L1+L2 from the building to L1+L2 in the car.
Fixed L1+L3 from the building to L1+L2 in the car.
Fixed L2+L3 from the building to L1+L2 in the car.
Fixed L1 from the building to L1 in the car.
Fixed L2 from the building to L1 in the car.
Fixed L3 from the building to L1 in the car.


There is also a strategy to automatically detect a car using one or two phases. The strategy measures actual charging for a few seconds and then switches to the least loaded phase or phases.

A number of PhaseBoxes deployed into an area will automatically compensate for imbalances between phases of the distribution network. This will lead to an increase in the local distribution capacity.

The power usually has to be limited in one way or another when charging several cars at the same time. One way is to limit the number of phases to one or two that is provided to each car. To achieve balance between phases when cars randomly start charging, chargers are distributed between phases in a hardwired way. The problem with this approach is obvious; everything is permanently connected and not at all dynamic. The system is therefore easily overloaded.

If the system is based on PhaseBoxes with automatic phase selection, the chargers will automatically connect themselves to the lowest loaded phases. Every charger can also be configured to use any phase strategy.
