Overview

The following list shows EV charging station manufacturers, supported by Teleport. Under each manufacturer, you can find more information on supported assets, configuration requirements, and device installation guides. Some assets are compatible off the shelf with the default factory settings, others require changes to their configuration.

Distribution logic

When several EV charging stations (e.g. when packed in an EV charger group) share an allocated power limit, for example one set by the EV power limiter, the available power is distributed over all present connectors (or plugs). A connector could either have a car connected, or no car connected. The distribution logic runs about every 5 seconds. In each cycle, it decides which connector has a car that wants to charge, estimates how much power each car could use, and then distributes the available power.

Most cars don’t report how much power they demand, so the Teleport estimates it from recent consumption. If there isn’t enough power available to satisfy demand, a priority list decides which cars may charge first. Cars are ranked in this order:

  1. Connectors with a car charging for less than 30 minutes, shortest charging first.
  2. Connectors with a car wanting to charge, but blocked from doing so, longest blocked first.
  3. Connectors with a car charging for more than 30 minutes, shortest charging first.
  4. Connectors with no car connected.

The available power is then allocated as follows, where the ranked priority order mentioned above is followed for each step, until the allocatable power budget is gone:

  1. Some chargers go into idle/standby state unless they get at least their minimum operating power (e.g. 1kW to stay turned ‘on’). If this is the case for a specific charger, this minimum power is assigned.
  2. The connectors with a car connected that wants to charge, are assigned the minimum charging power to trigger a charging session (e.g. 5kW).
  3. The remaining power is distributed over the connectors with cars that want to charge, proportionally to their demand.
  4. If there is still remaining power budget left, this is distributed over the other connectors where there is no car connected. This allows for fast ramping at the moment a car connects. However, it is expected that this power will not be drawn by the connector until a car connects.
