The current EU regulation on emissions for cars is the strictest worldwide. Along with further restrictions the thresholds cannot be met with conventional cars only anymore. One alternative technology, reducing the local emissions, are electric vehicles (EVs). For a successful market penetration, a functioning infrastructure is necessary. Customers rank inadequate access to charging stations as the third most serious barrier to EV purchase, after price and driving range ( Mckinsey, 2018 ). Therefore, public charging systems for electric vehicles support the electrification of urban mobility systems. While price and driving range improves each year, chargers can be of different power ranges and charging technologies. In addition, they can be smartly integrated into the local grid and provide information about the system for customers, operators and other stakeholders. For the user experience, it is recommended to include a payment and authentication system, which facilitates the access and enhances the transparency of the charging process. It is also an issue of access to charging stations, as charging is performed while the car is parked, and the possibility to book parking spots (adjacent to the charging station) is legally challenging in many countries. Dedicated parking spots for EV’s only do not solve the issue, as another (fully charged) EV can park for long term on the spot for which one account for charging after arrival.

Most cars are idly parked 90-95% of the time. With an accelerated shift to using electric vehicles (EVs), batteries of EVs offer enormous potential in terms of using their vast collective storage capacity as a flexible solution to support the grid, which can be taxed with an intermittent renewable energy supply. Bi-directional electric vehicle charging (V2X) refers to EV chargers that allow not only for charging the battery of the EV but also for taking energy from the car battery and pushing it back to the grid when needed. There are two primary receivers of power from an EV: the grid (V2G) and the electricity from a home or building (V2H). Bi-directional charging creates greater synergy between the clean transport sector and renewable energy sources, as the car batteries can store excess energy created by variable renewable sources, such as wind and solar, and then provide power to the grid or home when demand is high or energy production is low. This reduces curtailment, lowers the need for grid infrastructure investments and allows for higher renewable energy integration. In addition, V2H charging can act as an emergency power source during power outages, and V2G can provide vehicle owners with extra income through arbitrage of time-variable energy prices.

Citizen engagement is defined as the two-way interaction or communication between citizens and the government. This process is continuing to play an instrumental role in the way human settlements are being governed. Decision-making processes are enhanced by engaging those most affected and intimately connected with societal challenges. As much as traditional means such as public forums, town hall meetings, etc. still have relevance, more innovative and convenient forms of citizen engagement are advancing the ways in which citizens can partake in governance procedures. Despite the variations in the form in which citizen engagement may take place, it should ideally be characterized by a clear purpose and goal, clear structure and process, documented influence on decision-making processes, and present opportunities for inclusive and continuous representation. The major components of citizen engagement are illustrated in the figure below. Main Design Components of Citizen Engagement ( Daher E., 2021 )
