Optimization of Charging Infrastructure for Fleet Customers

2024-26-009201/16/2024

In a rush to move towards a sustainable future, the number of electric vehicles has risen significantly in recent years. With this, the need for power to charge those vehicles has also increased. In any electric vehicle fleet location, there could be a large number of vehicles with different arrival and departure times and energy requirements, which might vary every day. Depending on the geographical location, the available solar energy might differ. The electricity costs might change on an hourly basis. This in total can affect the charging costs. In addition, a non-optimal sizing of the energy components could result in an under-sized system, where the energy demands are not met, or it could result in an over-sized system, where the owner has to invest more than required. Based on all the information related to vehicle charging load, electricity charges, energy intensity profile of renewable energy generation like solar and wind, an optimal size of components, operational cost, and

Connecting sensors

OFHAPR07_0304/01/2007

Suppliers and road construction OEMs have teamed to develop an application profile for sensor interfaces. In most road construction equipment, operators need similar types of measurement data from sensors, including position, level, machine speed, distance, roughness, material core temperature, mass flow, and climate data. The sensor controller, a programmable device that processes the sensor values, normally collects the sensor information. In the European research project OSYRIS (Open System for Road Information Support) the participating companies chose the CANopen application layer. Supported by the European Asphalt Pavement Association, the pre-developed profile specification has been handed over to the international users and manufacturers group CAN in Automation (CiA) for further development and maintenance. To improve the sensor interfaces, several CiA members have developed the CiA 415 CANopen sensor system application profile for road construction equipment. One of the

Integrated Communications Architecture for Road Transport Informatics

91283910/01/1991

The field of Road Transport Informatics (RTI) has spurred a substantial interest in the development and adaptation of a diverse range of technologies for vehicle-infrastructure communications. Candidate technologies for early implementation include FM RDS-TMC, short-range beacons and cellular mobile radio GSM. This paper reviews some of the major characteristics of these systems and debates some of the issues influencing the design and integration of communications technologies for RTI. Next, a possible integration framework which essentially acts to decouple RTI applications from communications networks is described. The aim is to facilitate end-to-end communications between any two application systems which need to communicate, regardless of the network to which each is attached. This concept leads to the notion of a virtual RTI network and is currently under investigation to determine its viability and applicability.

Fast Replacement or Heavy Maintenance

53025001/01/1953

FAST replacement - with maintenance reduced to the lowest point consistent with safety - is the theme presented by this author. On the basis of TVA fleet policies, he argues the case for fast replacement. He follows up with an analysis of the question: when is fast replacement fast? He cites high job-shop overhead costs, which makes unit replacement of accessories, and early replacement of vehicles, economically inviting - except for large, special trucks. He proposes mass-production overhaul of components on large-volume, nationwide basis. He emphasizes the need for balanced component designing, looking forward to a future when all components in one vehicle will wear out together.
