Charging station overview

Under Stations, three major components can be created and managed:

  1. Charging station
  2. Charger
  3. Connector

The charging station represents the networking component that can be connected to EV Charge, while the charger represents the hardware component of the charging infrastructure.

Charging Infrastructure Status

Charging station has a status that represents the operational availability of its charging components (chargers and connectors). This is displayed based on the reports from the charging infrastructure.

The broad operational statuses are as follows:

Operational StatusDescription
OperativeCharging component is operating.
InoperativeCharging component not operating.
ClosedCharging component has been discarded and is not in use anymore.

They can be further specified based on the individual state of each charging infrastructure component.

Infrastructure Status

Here’s a detailed overview of each specific status:

AvailableIndicates that the charging infrastructure is available to a new driver.

Preparing / OccupiedIndicates that charging infrastructure is no longer available for a new driver, but there is no ongoing session (yet). Usually indicates that user presented a tag, inserted the cable or vehicle occupies the parking spot.

ChargingIndicates that EV is being charged by the charging device.

Suspended EVSEIndicates that EV is connected to the charger, but the charger is not offering energy to the EV. Reason could be load balancing restriction, local power supply constraints, or other limits.

Suspended EVIndicates that EV is connected to the charger and the charger is offering energy, but EV is not taking any energy.

FinishingIndicates that the charging session has stopped at the charging infrastructure, but infrastructure is not yet available for a new user. It can mean that cable has not yet been removed or the vehicle is still occupying the parking spot.

ReservedIndicates that charging infrastructure is reserved.

UnavailableIndicates that charging infrastructure is not available for use by drivers.

FaultedIndicates that charging infrastructure is not working/set-up properly.

ClosedIndicates that charging infrastructure is not in use any more.


Under Stations, there are two sections, namely:

  1. List view
  2. Map view

List view

Under the list view, a paginated list of all charging stations is shown in a tabular format.

To generate the stations’ list in a spreadsheet, click CSV. To print, click Print, and to copy, click Copy.

Six actions/subpages can be performed/viewed under this section, namely:

Create station

Under stations, to create a station, click Create. Provide a name and code for the charging station.

You can choose whether the charging station should be visible/invisible in the EV Charge - Mobile App. To achieve this, use the Visible toggle switch to enable/disable. This is handy if there is a testing station you do not want end users to see in the EV Charge - Mobile App.

As stated, invisible stations are hidden from the map, but exceptions can be made for the drivers which are station area operator’s private group members. See more.

The Physical address represents the MAC address of your charging station. In EV Charge, it is for information purposes; however, it can be helpful for inventory management.

The Communication protocol, which can be OCPP 1.6 or 2.0, is crucial. It specifies the protocol your charging station uses to communicate.

In addition, assign the charging station to a charging area. This will determine the position of the charger(s) on the map both for you in EV Charge and end users in the EV Charge - Mobile App.

The Boot configuration indicates whether EV Charge needs to execute a basic configuration for the charging station when it boots and connects to EV Charge. It covers charger/connector status synchronization and resets the charging profiles for energy rate limits. Use the Boot configuration toggle switch to enable/disable.

By clicking Save, EV Charge will create a template of the charging station (which represents your charging station).

Details station page

Under stations, to see the full details of a charging station, click Details. It contains the following:

  • Area
  • Serial number
  • Model
  • Vendor
  • Firmware version
  • Modem iccid
  • Modem IMSI
  • WebSocket

The WebSocket links are provided automatically by EV Charge. The WebSocket URL links connect your charging station to EV Charge. It contains a unique identifier assigned by EV Charge for your charging station.

Given the WebSocket URL link:


Breaking down the link:  # Tridens Server IP

/ev-charge/gw-comm/   # endpoint

1-4   # the unique identifier of your charging station assigned by EV Charge

Connecting to EV Charge

The WebSocket URL link (ws:// should be configured into your charging station. Then, your station will send a handshake request to EV Charge to establish a connection; it follows this order:

  1. Your station introduces itself as 1-4 through the handshake request.
  2. EV Charge checks if the unique identifier (1-4) is a valid identifier of a charging station created in its system.
  3. A successful connection is made if it is a valid identifier.

After a successful connection, the information from the handshake request will be populated in EV Charge. It can include the following:

  • Serial number
  • Model
  • Vendor
  • Firmware version

The charging station then becomes connected/operative in EV Charge.

Disconnecting from EV Charge

Under details station page, to disconnect the charging station from EV Charge, click Disconnect.


Under details station page, specific live configuration parameters/variables with their values can be read from your charging stations. To achieve this, first, click Configuration. Then, on each configuration, click Read from station. In addition, you can change and push back the specific live configuration values.

Update station

Under stations, to update a charging station, first, click Details; it shows the details of the charging station. Then to update, click Update.

Delete station

Under stations, to delete a charging station, click Delete.


The charging station created in EV Charge represents the networking component. Once the charging station is created, a representation of your physical charger and connector can be created. To create a charger in EV Charge, see create charger.

Create charger

Under details station page, to create a new charger, click Create New Charger.

Provide a name and code for the charger. The charger’s name will be visible to end users in the EV Charge - Mobile App. The code is automatically populated; however, it can be modified as long as it is unique for each charger.

The charger’s code is vital in EV Charge. Through the code, you can generate a QR code for the charger. Therefore, end users can start a charging session in the EV Charge - Mobile App using the QR code. For more information, see Scanning a QR code.

Once the QR code is generated for the charger, it can be printed and pasted on your physical charger for end users to scan to start a charging session.

For a charger with two or more connectors that can be used simultaneously, when generating a QR code, the connector code must be included in the charger’s code as part of the text that gets converted to a QR code.

The Physical address represents the MAC address of the charger.

Reservable indicates whether the charger allows reservations. For more information, see Reservations. Use the Reservable toggle switch to enable/disable.

Roaming indicates whether the charger is available for roaming. For more information, see Roaming. Use the Roaming toggle switch to enable/disable.

The Electric current type represents the charger’s electricity flow setup.

The Charging profile limits the charger’s power output based on a fixed schedule. For instance, the charger outputs a maximum of 20kW of power at night. While at day, the output is lowered to 10kW of power. For more information, see Charging Profiles.

The Custom field is a key-value pair, enabling you to include additional information for the charger.

The Custom field can also be used to categorize and parameterize your charging infrastructure.

For instance, suppose the key-value pair for a location category:


By assigning these parameters to the charger as custom fields, in Monetization, when defining the prices that end users would pay, the parameters can be used to affect the price. For example, chargers in the city can be more expensive than those in the suburb.

Create connector

Under create charger, to create a connector, click Create New. Provide a name and code.

The connector types are standardized types that let your end users know in the EV Charge - Mobile App whether or not the connector is compatible with their vehicle.

The Voltage limit represents the connector’s maximum electric voltage limit (Volts).

The Amperage and Wattage limit depicts the connector’s maximum capability. They are used exclusively when EV Charge is performing dynamic load balancing (whether current or power-based dynamic load balancing).

Regardless of the charging area configuration for the area output limit, the amperage and wattage limit configuration will not let the connector exceed the specified value.

For instance, for a 22kW connector, the wattage limit will be configured to 22,000.

In addition, end users in the EV Charge - Mobile App can filter for a connector based on the minimum power a connector can supply. The filtering option is based on the wattage limit configured for the connector.

The Power factor represents the relationship between current and voltage and must be between 0 and 1.

A connector can have a Custom field, which can be used for parametrization and categorization. For example, if you have a charger with two connectors, with one charging faster. The price for the connector with a faster charge rate can be higher.

By clicking Save, the charger is added at the bottom of the details station page. Also, the charger will be visible in the map view in EV Charge. Furthermore, the charger and the connector(s) will also be visible to end users in the EV Charge - Mobile App.
