With the increasing number of electronics loads dedicated to both security (ABS, ESP …), comfort (air conditioning) and entertainment (DVD) in vehicles, it has become critical to study the interactions between them. The transient phases due to on/off switching of electric loads can generate variation of the DC voltage that can influence loads behavior. It has then become important to develop a complete model of the embedded electric network to study loads interactions. First this goes through developing accurate models to help the designers in the sizing of the on-board power system as soon as the first steps of the new vehicle life. In this paper we present (i) the modeling of several components of a 14V automotive network (alternator and loads), and (ii) the experimental network that was set-up to validate the models. Finally, simulation results and measurements are compared and analyzed for transient events (load steps).Index Terms -on-board electrical network, automotive, modeling, alternator, light bulb, load step.

Throughout the history of the automotive industry, the average load on the electrical system has been increasing model year by model year. The main driver of this trend has been the increasing use of electric power due to the increasing level of equipment on the average vehicle. The electric power system of a modern vehicle has to supply enough electrical energy to drive numerous electrical and electronic systems and components. Usually, the electric power system of a vehicle consists of two major components, an alternator and a battery, with supplementary control systems sometimes used to aid system operation. For vehicle power supply analysis, a detailed understanding of the operational characteristics of the major components and how they interact as a part of the electric power system, including environmental and road conditions, is essential if the analysis is to aid system optimization. In this study, a simulation tool has been developed using SABERA® to enhance the process of vehicle electrical power system design, development, and optimization, which is becoming important as more electrical features are added to future vehicles.

Electrical power requirements for vehicles continue to increase. Future vehicle applications require the development of reliable and robust power supply strategies that operate over various ambient temperatures and driving conditions. Insufficient charge balance is one of the major concerns for conventional lead-acid battery systems when operated with limited charging times during short journeys or extreme climate conditions. For vehicle power supply analysis, a detailed understanding of the operational characteristics of the major components and how they interact as a part of the electric power system, including environmental and road conditions, is essential if the analysis is to aid system optimization. This paper presents a model based technique that enhances the process of vehicle electrical power system design. Vehicle system optimization using virtual prototypes has become critically important as more electrical features are added to future vehicles. Real vehicle data has been used to validate the models performance against specific design acceptance criteria. The validation measurements have been performed for different battery and ambient temperature conditions in order to demonstrate the accurate prediction of the simulation and modeling approach.
