When we look at the data, the picture is quite clear.: The number of electric vehicle users in Türkiye has increased 5.5 times in the past four years. With this incredible rise, we became one of the top 10 countries selling the most electric vehicles worldwide and ranked 8th in world market share. The biggest reason for this rapid climb is the rapid development of the infrastructure required for electric charging stations. As of November, 15,327 AC (Alternating Current) and 9,769 DC (Direct Current) charging points are in service in our country.
Beyond power level differences, charging performance is heavily influenced by battery management system (BMS) strategy and cell chemistry. Lithium-ion batteries follow a constant current–constant voltage (CC-CV) charging profile. During the initial phase, high current can be applied safely, but as the state of charge increases, the charging current must gradually decrease to prevent lithium plating and thermal stress. This means that even if a charger is rated at 350 kW, the vehicle may only accept that peak power for a limited portion of the session. Real-world charging curves, not just nameplate values, determine user experience. There are two main types of electric vehicle charging:
AC (Alternating Current) Charging: It usually occurs in homes or places parked for a long time. The battery is charged thanks to the charger inside the vehicle. When charging with an AC charging station, the electrical grid connects to the in-car charger and provides communication. The station tells the vehicle how much current it can draw and prevents the grid from being overloaded. Its power is usually up to 22 kW, and the charging time is relatively long. It is quite common in homes thanks to its low cost and easy installation.
DC (Direct Current) Charging: Provides faster and higher power charging. The DC charging station converts AC current directly into DC current and sends this current to the vehicle’s battery. Since DC chargers deliver direct current to the battery, they disable the vehicle’s own charger and can charge the battery in a much shorter time. Power levels typically start from 50 kW and can go up to 350 kW. This high power provides a great advantage, especially on long journeys or in situations where time is limited.
Grid impact becomes a critical issue as high-power DC chargers multiply. A single 350 kW charger operating at full capacity can draw as much power as dozens of residential apartments combined. When multiple fast chargers are installed at highway service areas, local distribution transformers and feeder lines must be reinforced. In some cases, medium-voltage connections and dedicated substations are required. Without proper load planning and demand management strategies, rapid charger deployment can create voltage fluctuations and peak demand stress on urban grids.
Rapid Development of Charging Infrastructure
High-power charging efficiency is not solely about conversion performance inside the station. Thermal management plays a decisive role. At power levels above 300 kW, liquid-cooled charging cables are commonly used to prevent overheating and maintain safe conductor temperatures. Similarly, vehicle battery packs require active cooling to sustain repeated fast-charging sessions without accelerated degradation. The coordination between charger control algorithms and vehicle thermal systems directly affects charging speed consistency and long-term battery health.
The number of charging stations in Türkiye increased by an impressive 235 percent in 2024. The main reason for this increase was the elimination of “charging anxiety”, which was one of the biggest concerns of users considering purchasing an electric vehicle. In the past, charging times that lasted for hours were seen as a major disadvantage compared to internal combustion engine vehicles. However, new generation fast charging systems have completely changed this perception. SICHARGE D high-power fast charging station, which comes with 400 kW charging power, clearly demonstrates the technological progress in this field by offering one of the highest rates in the market with a maximum efficiency value of 96 percent. It reduces charging time to 15 minutes, and this space-saving system with its compact structure also contributes to global CO2 targets.
One of the biggest factors in the growth and self-improvement of charging stations is undoubtedly the development in battery technologies. The speed and efficiency achieved by today’s charging stations are directly supported by developments in battery technology. Batteries are no longer just elements that provide energy transfer. They emerge as systems that are smart, easily integrated and prepare themselves according to changing conditions.
Smart Charging Management with Battery Management Systems (BMS)
Smart urbanization introduces another layer: energy management integration. Charging stations are increasingly connected to backend platforms that monitor occupancy rates, power consumption, and grid conditions in real time. Load balancing systems can dynamically distribute available power among multiple vehicles to avoid exceeding contractual demand limits. In advanced deployments, chargers communicate with distribution operators and respond to demand response signals. During peak grid stress, charging power can be temporarily reduced; during renewable generation surplus, charging can be incentivized. Electric vehicles thus become flexible grid assets rather than passive loads.
Battery packs are formed by connecting hundreds or even thousands of small battery cells in series and parallel. In theory, all of these cells should have the same capacity and properties. However, due to various factors such as manufacturing tolerances, temperature differences, internal resistance changes or charge/discharge cycles, small differences may occur between cells over time. These differences mean that some cells charge faster or discharge earlier than others; well cell imbalance emerges. BMS systems serve as an interface to battery systems. By instantly monitoring the voltage, current and temperature values of each battery cell within milliseconds during charging, BMS instantly detects and corrects any cell imbalance. These balancing mechanisms ensure that all cells of the battery are charged equally, preventing capacity loss and extending the overall life of the battery.
Vehicle-to-Grid (V2G) capability represents a transformative step for Türkiye’s energy ecosystem. In bidirectional charging architectures, electric vehicles are not only consumers but also temporary energy storage units. During high demand periods, aggregated vehicle fleets can feed stored energy back into the grid, supporting frequency stability and peak shaving. Technically, this requires compatible power electronics, communication standards, and regulatory frameworks that define compensation mechanisms. If implemented at scale, V2G could convert the rapid growth of electric mobility into a distributed energy resilience advantage for urban infrastructure.
Future Strategies and Urbanization Plans: How Can Smart Grids Be Integrated into Daily Life?
Electric vehicles and charging infrastructure are among the critical elements that will shape the future of cities, not only for individual users. Increasing city population and environmental problems have made it necessary to make the transportation infrastructure more efficient, sustainable and smart. Electric vehicles are at the heart of this change. In the future, smart grids and smart charging solutions will be indispensable in city planning to establish an integrated transportation system. Smart grids will not only manage the charging of electric vehicles, but will also optimize the city’s energy ecosystem by integrating with renewable energy sources. Electric vehicles will be used as part of demand management strategies; For example, when the load on the grid is high, vehicles will be able to return energy (V2G – Vehicle to Grid). This two-way energy flow will enable both charging stations and the city’s energy infrastructure to become more flexible and durable. In addition, smart charging stations, which will become widespread in cities, will be supported by user-friendly software. Mobile applications will provide information such as real-time charging status, station occupancy rate and payment options. Thus, drivers will be able to easily find charging points and charge comfortably even during busy hours. All these developments herald a future in which transportation and energy systems are intertwined, carbon footprint is reduced and more livable cities are built. These strategies developed for cities; It will revolutionize not only the use of electric vehicles, but also in areas such as energy saving, traffic regulation and environmental sustainability. As smart grids become integrated into our daily lives, it seems inevitable that modern cities will move towards a “smarter and cleaner” future.
The rapid development of electric vehicles and charging infrastructure will radically transform not only transportation, but also energy management and city life. Growth in this field in Türkiye is supported by innovative technologies and strong infrastructure investments. In the future, more environmentally friendly, efficient and user-friendly solutions will come into our lives thanks to smart grids and fast charging systems. Additionally, this dynamic sector creates a huge market opportunity for investors and leads to the emergence of new business models. In this regard, it can be said that we are witnessing the birth of a new sector in the e-mobility ecosystem.
