Phase utilisation

INFO

Damage to the electric vehicle is possible when switching phase usage

The Wallbox includes the option to switch phases whilst charging is in progress.

As some vehicles currently on the market are not compatible with a phase change whilst charging is in progress, automatic switching may, in isolated cases, cause significant damage to the vehicle.

Please check with your car manufacturer to confirm whether your vehicle supports this function. If not, please disconnect the vehicle from the Wallbox before a phase switch can be carried out.

When switching automatically between 1-phase and 3-phase charging (dynamic phase switching), the switching time can be adjusted via the ENECTOR G2 wallbox web interface under Settings > General > Phase Switching Pause if required.

By default, this is set to ‘short’ (2 minutes), which is supported by most vehicles. Changing this to longer or shorter intervals is not recommended, as this could lead to malfunctions in the control system of the PLENTICORE G3 with MDC.

Selecting the ‘immediate switching without pause’ setting is strongly discouraged, as this may cause damage to the vehicle. Liability for any damage resulting from the use of this setting is excluded – to the extent permitted by law.

• Off: Phase switching is carried out immediately without a pause
• Short: Switching time 2 minutes (standard / pre-configured)
• Medium: Switching time 6 minutes
• Long: Switching time 10 minutes

Selection of phase usage

Select here the maximum number of phases you wish to use to charge your electric vehicle.

• Standard (3-phase)
  A three-phase electric vehicle can be charged at a power output of between 4.1 and 11 kW. However, you can use this setting to charge all electric vehicles, whether single-phase, two-phase or three-phase. The maximum charging power is determined by the electric vehicle.
• Single-phase
  The electric vehicle can be charged at a power output of between 1.4 and 3.7 kW.
  For three-phase electric vehicles, you can use this setting to switch the number of phases from three-phase to single-phase charging, thereby reducing the charging power to 1.4–3.7 kW. This is useful, for example, if you wish to use Solar Pure Mode but do not have sufficient solar energy available (e.g. in spring or autumn). In this case, the vehicle can be charged using solar energy alone from as little as 1.4 kW of surplus power.
• Automatic
  With automatic phase switching, the wallbox automatically switches between single-phase (1.4–3.7 kW) and three-phase (4.1–11 kW) charging. This makes the entire charging range from 1.4 kW to 11 kW available for charging the electric vehicle. In Solar Pure charging mode, this means that, for example, if the surplus PV output is between 1.4 and 4.2 kW, a charging session can be started in single-phase mode. If the surplus PV power rises above 4.6 kW during the charging process, the charging is automatically switched to three-phase. When the system switches phases, the active charging process is always interrupted first and only then restarted with the new phase setting.
  
  Automatic phase switching procedure:
  When the charging process starts, the system checks whether the surplus PV power is sufficient for three-phase charging. If this is the case, the charging process starts in three-phase mode. Otherwise, it starts in single-phase mode. Every 15 minutes, the system checks whether it is possible to switch to three-phase charging. For this to happen, the available charging current must be 7 per cent above the minimum charging current required for three-phase charging. If this condition is met, the system switches over. If three-phase charging is no longer possible – for example, because the PV output is insufficient due to cloud cover – the system attempts to switch to single-phase charging after five minutes. If the available surplus power is insufficient for this as well, the charging process is paused.
