Fast photovoltaic array reconfiguration for partial solar powered vehicles

Published: 11 August 2014 Publication History

Abstract

This paper demonstrates that a partially solar powered EV can significantly save battery energy during cruising using innovative fast photovoltaic array (PV) reconfiguration. Use of all the vehicle sur- face areas, such as the hood, rooftop, door panels, quarter pan- els, etc., makes it possible to install more PV modules, but it also results in severe performance degradation due to inherent partial shading. This paper introduces fast online PV array reconfigura- tion and customization of the PV array installation according to the driving pattern and overcomes the partial shading phenomenon. We implement a high-speed, high-voltage PV reconfiguration switch network with IGBTs (insulated-gate bipolar transistors) and a controller. We derive the optimal reconfiguration period based on the solar irradiance/driving profiles using adaptive learning method, where the on/off delay of IGBT, CAN (control area network) delay, computation overhead, and energy overhead are taken into account. Experimental results show 25% more power generation from the PV array. This paper also introduces two important design-time optimization problems to achieve trade-off between performance and overhead. We derive the optimal PV reconfiguration granularity and partial PV array mounting by the car owner's driving pattern, which results in more than 20% PV cell cost reduction.
