We're making minor improvements to our OCPP message handling.

Enhancements​

• Improved handling of DeviceTimestamp in disconnect messages to more accurately reflect the actual charger disconnect time.
• Added support for the EVSE component in OCPP 2.0.1 configuration values.

Bug fixes​

• Fixed a rare concurrency issue in charger status handling. WebSocket connection flickers should no longer leave chargers in an inconsistent state.

This update will be rolled out in the coming days. The chargers will not experience any connection drops or downtime because of this change.

We are bringing a bunch of small but requested features with this release to both Connect and APIv2.

New features​

Connect​

• Show charger name on the driver charger access list
• Show charger name and socket name on the charging sessions list and Excel export

APIv2​

• Added externalId and RFID filters to GET /drivers
• Exposed charger name and socket name to GET /transactions
• By default pushIntegrationEnabled is set to true when adding new chargers

We are currently working hard on bringing our tariff engine to Connect, but in the meanwhile we have been able to do a couple of small improvements. New features for this release are listed below.

New features​

• New sessions tabs for site, charger and driver pages. No need to jump between Charging Sessions and the current page anymore!
• Search now supports charging session ids and returns corresponding charging session.
• Other small bug fixes

OCPI 2.2.1 support is out!​

From now on we support OCPI version 2.2.1 for new OCPI integrations! OCPI 2.2.1 is available for new integrations if that is supported by the OCPI partner. If you are currently our OCPI partner and want to move into using OCPI 2.2.1 with us, please open a service ticket and we will handle the rest.

🐛 Bug fixes​

• RFID tokens over 20 characters in length sent over OCPI are now properly handled to prevent rejected remote starts

We are introducing further improvements on the operational side of Connect with the new session page and DLM. With the new session page you have better view of what has actually happened during the session based on different metrics. The same timeline which you have seen on the ongoing sessions is also available in finished sessions now.

DLM is now also available in Connect. Currently the functionalities match the exisiting one from eMabler UI, but we are actively working on bringing new feature to DLM. In Connect the DLM page has received some new features like for example better visibility of how much currents are the subsites using and the history of the charging profiles sent to the chargers. Read more below!

Session page​

New session page is now available under Charging sessions > View on the individual charging session row. On the new session page you can see session details, session cost development, different metrics and the timeline of the session. Cost development contains the energy consumption and the cost development during the session. Metrics show energy consumed, power, state of charge, amperage and voltage changes during the session if charger has provided that information. Timeline shows the different events during the session, which makes it easier to troubleshoot finished sessions if need be.

DLM​

You can now manage your DLM setup from Connect! You can add, edit and remove DLM configurations to your sites to start using our cloud-based load management. In Connect you can see metrics for the used amperage between different phases and also how current is being used between the parent and subsites. External meters, subsites and chargers are all now grouped in the "Circuit" view, so you can more easily see the whole picture where the current is being used at currently. We have also brought the charging profile history to Connect, so you will have more visibility of the decisions the DLM has made when assigning currents to different chargers.

Please note that we are actively developing DLM further, so you can expect to see new functionality for that in the near future, so stay tuned!

Other improvements​

• Added power ratings under socket, so you can add more wattage/amperage/voltage combinations to single socket now
• New filters to OCPP logs
• Fixed bug with consumption estimation being calculated wrong at times for ongoing sessions
• Fixed bug with Operators view not showing all operators if there are more than 100 operators in the list
• APIv2: renamed POST v2/charging-sessions to v2/transactions to better match existing naming scheme
• Other small bug fixes and UX improvements

eMabler has provided Push API for a long time, but before now it wasn't possible to set it up yourself. With Connect you can now setup Push API using Webhook, Kafka or Azure ServiceBus and start receiving different messages directly to your backend without the need to contact our customer support.

We have also heard your feedback regarding the difficulties on finding relevant information about ongoing sessions, so we wanted to address that. In this release we removed the "Ongoing sessions" under "Activity" from Charger page and moved it under a new Socket page. You can now easily see which sockets have ongoing sessions, click on the "View more" and get a more detailed view of the session. Try it out!

Push API​

You can find new settings for Push API under More > Settings > Developers. You can configure Push API to use Webhooks, Kafka or Azure ServiceBus. We support lots of different messages you can receive to your endpoints, for example ChargerState, ChargerBoot or Measurements messages. Instructions on how to take Push API into use can be found here.

Improved ongoing session view​

Ongoing sessions are now available under Socket page (click "View more" on the socket). You can now see an overview of the session with session type (Regular/Roaming/Express), start time, duration, RFID used for authorization, estimated consumption, latest amperage/voltage readings, last state of charge information (if charger provides one) and a chart of total energy consumption during the session. In addition to this you have the timeline of the session available with all status changes and messages from charger during the session. This will hugely improve the visibility of different events during the session, which will make it easier to troubleshoot possible problems.

Charger Details page with Sockets now shows ongoing sessions directly. No need to go to a separate page anymore. Click View more for further details about the socket.

New ongoing session view contains overview of the session and the complete timeline. Timeline contains all charger events that occured during the session with details provided by the charger.

Other improvements​

• Latest errors, going offline, reboots and network issues widgets in dashboard now show also charger name, not only charger id.
• Charger data tables now have EVSE ID column available
• Charger data tables have links to chargers also on the charger name column, so you can hide charger id column if you want
• Renamed Activity page under Charger to Events which now only contains Charger events. Ongoing sessions can be found under Socket > View more

Charger and driver imports via Excel are here! No more need to manually add chargers and drivers one by one for larger sites, which improves the operations efficiency even further. This and other improvements with this release are found below

Charger & driver imports​

New bulk imports for chargers and drivers with Excel are now available! Please find corresponding Excel templates for importing data in bulk under More > Import. Charger and driver imports work on a site level, so if there is a need for importing data to multiple sites, you need multiple Excel files.

Other improvements​

• OCPP logs can be exported to Excel
• Fixed site config manager not finding configuration values
• Other small fixes

Following our previous release which contained comment fields, we are further improving the operational workflows with sites and chargers with this release. Find everything for this release from below:

Charger installation details​

New fields available for chargers: "installation date", "parking place", "service company", "service contact person", "service email", "service phone number" and "notes"! By using these fields it is easier to keep track of the age of the charger and service company information.

We are also introducing new "parking place" field for sockets. Some charger setups are configured to report chargers as separate sockets, so this new field can be used to identify the physical location of that charger.

All of the new fields are also available through APIv2.

Site service details​

You don't want to keep track of service company information on the charger level? No worries, you can also do that on the site level. We are also introducing new fields for sites: "service company", "service contact person", "service email", "service phone number" and "notes".

All of the new fields are also available through APIv2.

Charger labels​

You can now add labels to chargers. These labels are visible under charger information and can also be viewed on Chargers list. Labels support a handful of different colors, so you they provide a versatile way of adding new information to chargers.

Note for our API users: labels use the "custom properties" field of the charger under the hood, so they are available through there.

Personal preferences​

We are introducing personal preferences under Settings. You can save your personal preferences such as language, time zone, country and currency which will be used to customize the user interface accordingly. Corresponding fields will also show your preference as the first option to make things extra easy!

Other improvements​

• Added column options for data tables. You can now reorder and hide columns as you wish and the settings will be saved.
• Charging remote starts can be initiated with a free text RFID now. By default a randomized RFID will be used, but you can manually change the RFID to which ever you want. No more need for drivers for more simple use cases.
• OCPP logs are now by default minified. You can expand the OCPP logs row-by-row by clicking "Expand", which will format the logs into a more readable format than before.
• Added "Select all" option when adding site access to operators and drivers.
• Changed date pickers to support free text inputs as well, so you can write the wanted date instead of having to click through the calendar when more appropriate.

🐛 Bug fixes​

Charging session handling​

• Improvements for consumption time series calculation when meter values are not aligned with transaction and themselves. Now total consumption in time series and transaction is set to be same (that was not always the case previously).
• If total consumption is going to be huge (> 500 kWh), it is set to 0 and no price is calculated.
• When total consumption differs from received meter values, the difference is now added to the last 15min slot that has consumption (not just to the last one).

Thank you everyone for the feedback regarding Connect beta release! The reception has been greater than we could have even anticipated, which is awesome to see.

Next we are releasing a new commenting feature to Connect, which makes internal communication much easier when doing operational work. We are also releasing success rate metric to dashboard and other small improvements on the platform.

Comment fields for sites, chargers and drivers​

You can now leave comments under sites, chargers and drivers. Comments allow you to document made changes in an easy way. Comment fields are available under sites, chargers and drivers.

Success rate for dashboard​

Our first step towards bringing better tooling to monitor your charger infrastructure performance is the success rate. Success rate is the key metric to see the percentage of successful charging sessions. We will be working on bringing you better tools to compare success rates between different manufacturers and charger models in the future.

Other improvements​

• Added manufacturer and model filters to Chargers page
• "Chargers" and "Subsites" columns now show the number of all chargers and subsites (including subsites) on the Sites page
• Data tables now handle loading state in a more graceful way, no more blocking loading animation if data is found from cache
• Fixed canceling user details update making Connect error
• Added missing "Clear charging profiles" and "Request diagnostics" charger actions
• Added links to Chargers page with corresponding status filters in "Sockets" in Dashboard
• Made site explorer more versatile under individual site and charger pages
  • Added links to previous and next sibling site
  • Added button for bringing focus back to the currently active site next to the search bar
