In May 2019, the International Renewable Energy Agency released "Electric Vehicle Smart Charging - Innovation Outlook." As an EV Vacuum Pump Factory, let's share some information with you.
Policy Summary: The emergence of electric vehicles (EVs) is expected to change the world's transition to sustainable energy, especially renewable energy. There are several reasons for this. Most notably, with the transformation of the transportation industry, electric vehicles provide a viable opportunity to introduce a higher proportion of renewable energy into the overall power generation structure.
Charging an electric car generates a lot of extra power demand. This can be achieved with renewable energy sources, including solar and wind. These developments offer an attractive prospect—especially for cities—while reducing traffic carbon emissions while reducing air and noise pollution, reducing dependence on fuel imports, and adopting new urban transport options.
The steady decline in the cost of renewable energy generation has made electricity an attractive low-cost source of fuel for the transportation sector. Expanding the deployment of electric vehicles also represents an opportunity for the development of power systems, potentially increasing the much-needed flexibility of power systems and supporting the integration of a high percentage of renewable energy.
From a power system perspective, electric vehicles are a unique innovation because they are not developed for the power sector and are not the primary solution for grid flexibility. Instead, their main purpose is to meet mobile needs. Therefore, to achieve the best use of electric vehicles, it is necessary to carefully study which use cases are most suitable for these two departments. Ideally, renewable energy-driven electric vehicles can bring a wide range of benefits to the grid without negatively impacting transportation functions.
Cars, including electric cars, typically have a 95% life cycle in the parking lot. These idle periods, combined with the storage capacity of the battery, can make electric vehicles an attractive and flexible solution for power systems. Each electric vehicle can effectively become a miniature grid-connected storage unit with the potential to provide a wide range of services to the system. At the same time, however, uncontrolled charging may increase the peak pressure on the grid, forcing the distribution network to upgrade.
The emerging innovations in smart charging for electric vehicles not only span the technology sector but also span the business model and regulatory framework (IRENA, 2019a). This is critical for integrating renewable energy while avoiding grid congestion. In addition, this innovative vision discusses the potential impact of anticipated mobile disruptions, including “mobile-as-a-service” and the widespread adoption of fully automated vehicles in the next two or three decades.
