EV Charging Software: The Backbone of Charging Infrastructure

EV charging software is a digital solution that helps e-mobility service providers and charging operators to monitor, manage, and optimize all operations and aspects of EV charging. This tool is designed to get insights into the complexities of EV charging hardware and contributes to making EV charging an effective, fast, and convenient experience. EV charging software exhibits multiple benefits, for instance, it helps in efficient energy management, easy payment processing, and addresses network issues and charger faults. As a result, this software has emerged as an ideal solution for both EV drivers and site owners and operators, as it plays a crucial role in offering efficient charging experience along with improving operational management.

Assessing Best-in-class EV Charging Solutions Available in the Market

Allied Market Research states that the EV charging software market is expected to account for $11.1 billion by 2032 from $1.1 billion in 2023, citing a CAGR of 28.9% from 2024 to 2032. This revenue growth is majorly fostered by factors such as rapid development of EV charging stations, especially in urban areas and along highways, and increase in penetration of EVs. As per a recent study published by the International Energy Agency, a Paris-based autonomous intergovernmental organization, the first quarter of 2024 witnessed sale of approximately 3 million EVs, around 25% higher as compared to 2023.

Furthermore, industry experts assert that of all the passenger cars sold in the U.S., EVs are estimated to account for 25-30% of these by the end of 2030. Furthermore, integration of AI is enhancing the capabilities of charging management software. According to a recent study published in IEEE Transactions on Smart Grid—a highly regarded, peer-reviewed academic journal published by the Institute of Electrical and Electronics Engineers (IEEE)—AI-driven approaches in energy management is anticipated to improve efficiency by up to 15%, thus enabling smarter, more sustainable charging solutions.

EV charging and infrastructure software fall into three major categories, including vehicle-based software, charging point software, and backend/infrastructure software. Vehicle-based software is integrated into EVs to manage and maintain the service life of battery, notify the driver about the remaining charge, estimates driving range, and locate nearby charging stations. It is developed by EV manufacturers or sourced from specialized vendors and integrated into vehicles during production. On the other hand, traditionally developed by charger manufacturers, charging point software is developed by ecosystem partners to reduce costs and support evolving standards. While EVs can be charged from basic outlets, smart charging stations use charging point software to match battery needs and connect to back-end systems. Moreover, it manages charging sessions by starting, monitoring, and ending the flow of electricity to the EV depending on the needs of vehicle and driver inputs. In addition, it ensures safe operation by examining temperature, voltage, and current to prevent overloads or faults. Back-end/infrastructure software is a cloud-based software that handles the backend operations such as  energy regulation, session management, station deployment, payments, and billing. Its main goal is to deliver a seamless user experience, regardless of charger type, location, or currency.

EV charging stations themselves are categorized by charging level, including level 1 chargers, level 2 chargers, and level 3 chargers. Level 1 chargers plug into standard outlets and provide the slowest charge of up to 20 hours for 120 miles. They are mainly used for plug-in hybrids or emergency charging due to their limited output. Contrarily, level 2 chargers are the most common public charging stations. They use higher voltage of about 208–240V. This enables faster charging up to seven times faster than level 1. They require a special connector, SAE J1772 and can also be installed at home for quicker charging. Furthermore, level 3 chargers, or DC fast chargers, provide the fastest charging. These use direct current and can charge a battery much more efficiently. Depending on the vehicle and region, they are available in different plug types such as SAE Combo, Tesla connector, and CHAdeMO. Overall, modern EV charging software must be hardware-agnostic and compatible with Open Charge Point Protocol to ensure interoperability across diverse charger types and networks.

Final Remarks

EV charging software has emerged as a fundamental solution for charging infrastructure as it ensures charging stations operate efficiently. Moreover, it helps to streamline operations and save energy costs, thus serving as the digital backbone of reliable, efficient, and sustainable EV charging infrastructure. Vehicle-based software, charging point software, and backend/infrastructure software together create a smooth, connected system that helps vehicles, chargers, and the power grid work well, making charging more reliable and efficient.
