The integration of solar photovoltaic(PV) into the electric vehicle(EV) charging system has been on the rise due to several factors, namely continuous reduction in the price of PV modules, rapid growth in EV and concerns over the effects of green house gases. Despite the numerous review articles published on EV charging using the utility(grid) electrical supply, so far, none has given sufficient emphasis on the PV charger. With the growing interest in this subject, this review paper summarizes and update all the related aspects on PV–EV charging, which include the power converter topologies, charging mechanisms and control for both PV–grid and PV-standalone /hybrid systems. In addition, the future outlook and the challenges that face this technology are highlighted. It is envisaged that the information gathered in this paper will be a valuable one-stop source of information for researchers working in this topic.

This paper reviews the PV–grid and PV-standalone EV charging methods proposed in various papers .It is noted ,among the two structures, the PV–grid is more popular due to its flexibility and its interruption-less operation . Also in this paper, the main hardware components, i.e. the dc–dc converter with MPPT ,bi-directional inverter and bi-directional dc charger are evaluated. Due to the rapid development, it is not possible to cover all aspects related to the EV charging infra structure in a single work. Other topics—for example , the economic and environmental impacts of PV and grid powered EV charging are addressed elsewhere [9,86]. Further- more, issues such as the stability, reliability and PV–EV interactions require detailed analysis that may not be feasible for inclusion. For the energy management systems, researchers are highly relaying optimization algorithms and soft computing. However ,it seems that the heuristic rule based charging strategies is a good solution for quick and accurate energy management as already been adopted by . But, there is still a need to devise more accurate techniques for better utilization of available PV energy.
