Notifications Setup Guidelines in General
Charging providers usually want to enable the notifying features, so they can inform the EV drivers about the status of their charging session or to inform themselves about the status of the charging infrastructure.
This section can serve as a guide on the options which can be utilized for the notifying. Base general steps for configuring the notifications can be found in Notifications section.
See the following references to find notifications setup technologies:
Notifying EV Drivers
EV drivers (also end users, end customers), usually want to be notified about the status of the charging sessions. Setup of these kind of notifications differs based on the session handling configuration, as described in Sessions - Session Rating Settings. Full list of available notification actions is described in Notifications Scopes and Actions.
The most used actions for notifying the EV drivers during the session by using the push notifications or SMS for mobile devices are the following:
Charging end - Indicating that session’s charging has ended, but parking fees may apply after. You can notify the driver that the charging process is done and prompt them to remove the vehicle.
Battery percentage limit - Indicating that certain amount of battery percentage (configurable) has been breached for the session, if reported by the charger. E.g., EV battery achieved 85%.
Energy limit - Indicating that certain amount of energy in kWh (configurable) has been spent for the session so far. E.g., EV session’s energy consumption achieved 40 kWh.
Charge time limit - Indicating that certain time for charging (configurable) has been spent for the session so far. E.g., EV session charging duration achieved 30 minutes.
Park time limit - Indicating that the certain parking time (configurable) has been spent for the session so far. E.g., EV session in parking mode duration achieved 15 minutes. Prompt driver to remove the vehicle and release the spot.
Park time threshold breach - Indicating that the parking time spent for the session has achieved the configured rating threshold of the EV charging session. From this point, parking time fees may apply. Based on configuration of Sessions - Session Rating Settings.
Monetary limit - Indicating that certain amount of money (configurable) has been spent for the session so far. E.g., EV session charging cost achieved 25€.
For the cases of notifying EV drivers by an email, the following actions may be useful:
Session end - Indicating that the charging session has ended and summary can be published.
Session refused - Indicating that the charging session didn’t succeed, as initial authorization of customer’s resources didn’t succeed.
Notifications are headed to the session’s driver/customer, when an action is related to the specific customer and notification rule’s receiver of type ‘Customer’ is selected. See Fig. 1 below. Applies for the session related actions, as these are customer related. Customer’s primary contact info is used for it, so push notification reference, email or phone number for SMS is taken from there.
See Notifications - Create Notification Rule section.

Content formatting definition example:
Charging session ${object.contents.session.id?c!'/'} ended.
Consumed ${object.contents.session.totalEnergy?c!'/'}kWh for the cost of ${object.contents.session.usedAmount?c!'/'}€.
Results in:
Charging session 9718 ended. Consumed 29.33kWh for the cost of 8.28€.
Notifying the Operators
Operators may be interested in being notified when significant changes appear on the charging infrastructure. Informing can be done by an email, SMS, logging or API call. Full list of available notification actions is described in Notifications Scopes and Actions.
Actions which can be especially helpful to operators:
Station connected - Indicating that the charging station has established a connection with the central system of Tridens EV Charge. If re-connections are happening, the station may need an urgent review.
Station disconnected - Indicating that the charging station has been disconnected from the central system of Tridens EV Charge. May need an urgent review, as connected station is necessary for availability of operations.
Station booted - Indicating that charging station has sent the boot notification. If the boot was not intentionally triggered, it may need a review.
Status changed - Indicating that the charger’s or connector’s status has changed. Advised to use notification for the transition to the ‘faulted’ status, as it usually needs to be troubleshooted.
Fault time limit - Indicating that certain fault time (configurable) has been spent for the charging session so far. E.g., EV session in fault mode duration breached 5 mintues. Needs operator’s review.
Operator related notifications are usually headed to the specific address (i.e. email), hence notification rule’s receiver of type ‘Base’ is usually selected with the contact populated. See Fig. 2 below.
Alternativelly, email sender (from) can be determined on email template as well.
See Notifications - Create Notification Rule section.
Fig. 2: Example of notification rule configuration headed to the specific operator’s email address when the charging station device disconnects from the central system and the occasion needs to be reviewed.
Content formatting definition example:
Charging station ${object.contents.charging_station.name!'/'} has disconnected from the central system. Id:${object.contents.charging_station.id?c!'/'} Code:${object.contents.charging_station.code!'/'} Address: ${object.contents.charging_station.address!'/'} ZIP: ${object.contents.charging_station.zip!'/'} City: ${object.contents.charging_station.city!'/'} Country: ${object.contents.charging_station.country!'/'} Latitude: ${object.contents.charging_station.latitude?c!'/'} Longitude: ${object.contents.charging_station.longitude?c!'/'}
Results in:
Charging station Tridens Building has disconnected from the central system. Id:5274 Code:f1db01db-3f7c-4804-9d9a-e54cb1037040 Address: Titova 2a ZIP: 2000 City: Maribor Country: SI Latitude: 46.56007700000001 Longitude: 15.6510651.
