TL;DR: In this article, the authors evaluated the performance of four different types of CHP plants to power electric vehicles, as compared to use of electricity from the grid, and found that the lowest abatement costs of 60-190 €/tCO2 are achieved with grid electricity based on a low-carbon electricity mix compared to a business-as-usual electricity mix with marginal emissions of 450-500 gCO2/kW h.

Abstract: A vehicle-mounted power supply system comprises a first storage battery, an automotive generator for generating electrical energy and charging the first storage battery with the generated electrical energy. A second storage battery is connected to an electrical load and a power converter supplies electric energy from the first storage battery to the second storage battery. A controller, or battery-monitoring unit, sets the power converter in a sleep mode when the vehicle engine is stopped, periodically detects the voltage of the second storage battery as a pseudo-open circuit voltage during the sleep mode of the power converter if current of the second storage battery is within a predetermined range, estimates a state of charge of the second storage battery from the detected pseudo-open circuit voltage and sets the power converter in a run mode when the estimated state of charge is lower than a predetermined value.

11 May 2010TL;DR: In this article, the authors proposed a hybrid power system for distributed generation of electric power for stand-alone applications at remote locations, where the main power comes from photovoltaic panels and wind generators, while the fuel cell and batteries are used as backup units.
Abstract: This paper shows the way to design the aspects of a hybrid power system that will target remote users. It emphasizes the renewable hybrid power system to obtain a reliable autonomous system with the optimization of the components size and the improvement of the capital cost. The system can provide electricity for a remote located village. The main power of the hybrid system comes from the photovoltaic panels and wind generators, while the fuel cell and batteries are used as backup units. The optimization software used for this paper is HOMER. HOMER is a design model that determines the optimal architecture and control strategy of the hybrid system. The simulation results indicate that the proposed hybrid system would be a feasible solution for distributed generation of electric power for stand-alone applications at remote locations.
