Abstract

Electric vehicles (EVs) and hybrid electric vehicles (HEVs) are growing in popularity. Onboard photovoltaic (PV) systems have been proposed to overcome the limited all-electric driving range of EVs/HEVs. However, there exist obstacles to the wide adoption of onboard PV systems such as low efficiency, high cost, and low compatibility. To tackle these limitations, we propose to adopt the semiconductor nanomaterial-based luminescent solar concentrator (LSC)-enhanced PV cells into the onboard PV systems. In this paper, we investigate methods of accelerating the reconfiguration algorithm for the LSC-enhanced onboard PV system to reduce computational/energy overhead and capital cost. First, in the system design stage, we group LSC-enhanced PV cells into macrocells and reconfigure the onboard PV system based on macrocells. Second, we simplify the partial shading scenario by assuming an LSC-enhanced PV cell is either lighted or completely shaded (Algorithm 1). Third, we make use of the observation that the conversion efficiency of the charger is high and nearly constant as long as its input voltage exceeds a threshold value (Algorithm 2). We test and evaluate the effectiveness of the proposed two algorithms by comparing with the optimal PV array reconfiguration algorithm and simulating an LSC-enhanced reconfigurable onboard PV system using actually measured solar irradiance traces during vehicle driving. Experiments demonstrate the output power of algorithm 1 in the first scenario is 9.0% lower in average than that of the optimal PV array reconfiguration algorithm. In the second scenario, we observe an average of 1.16X performance improvement of the proposed algorithm 2.
