Manual - EV Charging Station NS 2. Description and features 2.1. Description The EV Charging Station NS is an AC charging station for electric vehicles. It delivers up to 22 kW in three-phase mode or 7.3 kW in single-phase mode, with a configurable charging current of up to 32 A per phase. The charging station connects to the local network over WiFi. It is operated and monitored with the VictronConnect app over Bluetooth, in its own web interface, from a GX device, and from anywhere through the VRM portal and VictronConnect-Remote.
In a system with solar, the charging station can charge the vehicle from surplus solar energy once the house batteries are full and feed-in is active, instead of exporting that energy to the grid at a lower price. A programmable RGB light ring around the charging port shows the state of the charging station, with 55 configurable light effects. The tough plastic enclosure withstands harsh weather and can be mounted indoors or outdoors. The default cover is blue; black and white covers are sold separately. 2.2. Features Three operation modes: 1.
Automatic mode to ensure maximum PV system efficiency Thanks to the seamless integration of the EV Charging Station NS with the rest of the Victron installation, it detects when there is a surplus of solar power and uses this exclusively to charge the vehicle or, if desired, adds energy from the grid to cover the minimum power requirement, for example, if there is not enough surplus solar power. Note that this mode requires a GX device in your system and communication between GX device and EVCS enabled. For details, see chapter VictronConnect setup, configuration and operation [23] and GX device setup, configuration and operation [22] .
Instead of losing surplus energy when the batteries are full and, for example, feeding it back into the grid at a lower price, the energy is stored in the EV battery. Seamless integration into the Victron installation Detects when excess power is available and uses only that to charge the vehicle before exporting it to the grid Ensures maximum PV efficiency Battery-powered algorithm (used by default) for automatic mode ensures that automatic mode works even when off-grid How does it work? The EVCS will automatically start charging when the vehicle is connected and the following conditions are met: 1. The current state of charge is above the 'Start charging at backup battery SoC (%) value. 2.
There is enough excess solar power available, with excess solar power calculated as follows: Excess solar power = Total PV production - AC loads (without car consumption) = 1380W (230V x 6A) In the example above, the Min. charge current (from 6A) value has been set to 6A. The required excess solar power increases accordingly if a higher value is set for the Min. charge current (from 6A). Please see the chapter VictronConnect setup, configuration and operation [23] for details on both parameters. 3. Or, if there is not enough excess solar power available to meet the minimum charge current requirement as per 2., it is possible to enable the 'Allow low excess solar power for auto mode' option.
This option supplements the required power with additional power from the grid to meet the minimum current requirement. See chapter VictronConnect setup, configuration and operation [23] for details. 2. Manual mode to configure output current Manual mode allows configurable output current between 6-32A. The charging power is controlled in several ways: By using the web interface via a web browser From a GX device touch screen like the GX Touch 50 & GX Touch 70 . From the Remote Console By using the Controls on the Dashboard of the VRM Portal (requires a GX device) Page 2 Description and features
