# A Review on Standardizing Electric Vehicles Community Charging Service Operator Infrastructure
## 7 Conclusions  
In this paper, we present an exhaustive survey on standardizing EV charging infrastructure considering the taxonomy of charging levels, charging modes, charging standards, and charging technologies based on the different charging types such as conductive charging and wireless charging, and types of vehicle, i.e., 2W, 3W, and 4W. Moreover, we considered a scenario in which the community charging service operator manages the EV charging infrastructure at which users of a particular community can charge their vehicles. For that, we propose an architecture for standardized EV charging infrastructure to provide compatibility of the charging standards for efficient and durable charging. Finally, the research challenges and opportunities of the proposed survey have been discussed in this research area.  
In future work, we can consider one more charging type, i.e., battery exchange to explore more about the power supply, current, and efficiency of EVs. Additionally, we need to highlight one more charging standard, i.e., GB/T, in future to discuss supporting countries and manufacturers for the future. Additionally, we can implement the standardized charging standards in real-time scenarios to enable the adaptability and compatibility for the arriving EVs at a CS across the countries. However, the important aspects of charging cost and charging time need to be considered while implementing the standardized charging infrastructure for reliable charging so that it is affordable for the users. Another scenario needs to be incorporated to verify the adaptability and affordability of specialized CSs for EVs considering the different charging levels and modes such as DC or AC with different phases for charging.
