Electric vehicles are increasingly being adopted due to environmental awareness and competitive technical performance and reducing prices. Their research and development has sometimes relied on the use of standard driving cycles. However, these cycles cannot reproduce the variations of traffic flow in real world. That is why in this paper we develop a software tool able to analyze real-life driving...
Coordination and scheduling the charging of plug-in hybrid electric vehicles (PHEVs) in parking lots integrated with photovoltaic (PV) system presents both unique opportunities and challenges. In most of the cases PHEVs are assumed to stay in the parking lot for several hours. To facilitate the maximum usage of PV power, the charging times of PHEVs have to be scheduled to coincide with the periods...
Aiming to increase the vehicle performance, a method for real time monitoring of critical drive components is presented. Using the example of an interior permanent magnet machine, with gearbox attached, on the rear axle for a hybrid electric vehicle, a lumped parameter thermal model is introduced. Based on this analytic model, which is verified using measurements, a reduced model capable of real time...
This paper presents a new topology of an isolated multilevel inverter that can be used for high voltage and high power applications such as integrating battery storage systems and alternative energy sources to power grid. With reduced number of components the proposed cascaded multilevel inverter requires only one dc source by cascading high frequency transformers. The core building blocks in the...
The paper deals with the electric hybridization of a bow thruster for a river tugboat application. The knowledge gap leads to the full electrical retrofit of a previously high power hydraulic bow thruster system, in the objective of having more electrified subsystems in the boat, leading to an eco-friendly solution. This electrified solution feeding a Permanent Magnet Synchronous motor with on-board...
This paper proposes a program which defines the least costly vehicle following a driving cycle. An exhaustive research is making by the algorithm for find the optimal configuration of the car between the size of the batteries and the powers of the electrical machine and the heat engine. Cost during the life duration and performances are calculated for each configuration in order to determine optimal...
