Long Distance EV Routing

The Long Distance EV Routing service calculates a route between a given origin and destination. The route contains charging stops that have been added automatically based on the vehicle's consumption and charging model.

• Each charging stop results in an additional leg in the route response.
• Each additional leg contains a chargingInformationAtEndOfLeg element in its leg summary.
• Both the route summary and the leg summary include a remainingChargeAtArrivalInkWh element.
• The route summary includes a totalChargingTimeInSeconds element.

The chargingInformationAtEndOfLeg field consists of:

• target battery charge
• charging time
• details about the charging stop

This document assumes familiarity with the Calculate Route service and only describes how calculateLongDistanceEVRoute differs from it.

Prerequisites for Long Distance EV Routing support

There are two important prerequisites needed that differ from the Calculate Route service:

• The Electric Consumption Model must be set.
• At least one chargingMode must be supplied in the Request.

Unsupported calculateRoute features

As opposed to the Calculate Route service, the following features are not supported in Long Distance EV Routing:

• Route reconstruction:
  • Reconstruction of a reference route (given by a supportingPoints section in the POST data) is not supported. Consequently, the parameters minDeviationDistance and minDeviationTime are not supported.
• Waypoints:
  • The locations must contain exactly two points, the origin and the destination. Waypoints, and consequently the parameter computeBestOrder and the option routeRepresentation=none, are not supported.
• routeType values other than fastest are not supported.
• Alternative routes:
  • maxAlternatives and alternativeType are not supported.
• Instructions
  • instructionType and language are not supported.
• arriveAt is not supported.
• travelMode values other than car are not supported.
• computeTravelTimeFor is not supported.
• chargeMarginsInkWh is not supported.
• Long Distance EV Routing only supports json as the content type for its POST payload and encoding for its Response.
