VDV 463 (Charging Management Interface)
Standardized interface for data exchange between depot/ITCS “pre-systems” and charging management, so charging and preconditioning can be planned and synchronized for e-bus depots.
Technical Details
VDV 463 defines the data exchange process and format (intended to remain extensible as a configurable “variability point” for future formats). It includes dedicated structures for preconditioning, such as AutomaticPreconditioning (preconditioning request, ambient temperature, requested finish time), ManualPreconditioning (start times and auxiliary power setpoints), and PreconditioningInfo (time and energy needed for HV-battery and vehicle preconditioning, referencing VDV 261).
Fleet Applications
Improves operational reliability by planning charging together with preconditioning effort (time + kWh) and by aligning finish times with depot workflows (“unplug by” time). Supports both automatic and manual preconditioning scenarios, including unplanned trips.
