When diesel buses are converted to electric or hydrogen drive, operational processes and the requirements on the IT systems change. Flexibility and independence in the selection of manufacturers of ITCS, depot or load and charging management systems is the top priority.
PSI was the first provider to develop an interface for data exchange between depot (DMS) and charging management system (LMS) in a project with Hamburger Hochbahn AG that is unique in the country to date. It has already proven itself in use by various electric vehicle and charging station manufacturers in productive bus operations and is now in the publication phase as VDV Specification 463.
The standard describes, among other things, the exchange of information between DMS and LMS and defines the data format and transport protocol for this. Both charging in the depot and on the route are taken into account.
In the Depot Management System (DMS), the processed operational data is evaluated taking into account the disposition, supply and maintenance of the respective vehicles and the calculated charging requirement is transferred to the Load and Charge Management System (LMS). Conversely, the LMS provides information on vehicles, charging infrastructure and charging management to the DMS in an up-to-date and correctly prepared form so that the DMS can reliably carry out operational planning.
For many years now, we have been pursuing the goal of converting interfaces into a standard in order to ensure competitiveness and investment security and to enable our customers to freely select their suppliers. Through this extensive experience in the field of interface development, we can guarantee that all systems can be integrated.
