Against the backdrop of global energy transformation, the combination of photovoltaic power generation, energy storage systems and electric vehicle EV chargers is becoming an important part of the future energy structure. The construction of an integrated system of solar, battery energy storage and EV chargers is a major test of technical integration capabilities. Many companies fail due to technical barriers and integration difficulties when they try to deploy this system. However, SCU has successfully integrated the three systems seamlessly through its many years of energy storage and EV charger technology experience and customized services, ensuring efficient coordination between the systems. SCU has demonstrated excellent integrated solution capabilities, whether it is the absorption of solar power generation during the day or the intelligent scheduling of energy storage and EV chargers.
Background
The German user has already installed a photovoltaic system on his roof. The user hopes to use self-generated renewable energy to charge electric vehicles and maximize energy efficiency. To achieve this goal, SCU designed and deployed an energy management system integrating photovoltaics, energy storage system and EV charger.
The energy storage system provided by SCU for this project can store electricity during the peak period of solar power generation during the day, and release energy during peak electricity price periods or periods of insufficient sunlight for EV chargers and other load equipment. In this way, it can not only effectively reduce the pressure on the power grid, but also help users save energy costs significantly. In addition, the equipped intelligent management system can monitor and optimize energy use in real-time to ensure the efficient operation of the entire system.
Solution
SCU provides GRES-75-50 (BESS)+ Wallbox DC EV charger to form an integrated solar ESS EV charger system.
Core advantages of SCU Solar BESS EV charging System
Optimized scheduling of energy storage system
The energy storage system provided by SCU has flexible energy management functions. The system can perform peak-valley arbitrage operations according to the real-time needs of users and the dynamics of power grid electricity prices, store electricity when electricity prices are low, and release energy during peak hours to maximize the economic benefits of users. In addition, when solar power generation exceeds the actual needs of users, the energy storage system will store excess electricity for use at night or on cloudy days when solar power is insufficient, to achieve efficient use of energy.
Efficient and reliable charging solution
In response to the needs of electric vehicle users, the EV chargers provided by SCU are equipped with an intelligent control system that can be linked with photovoltaic and energy storage systems to flexibly allocate charging power. During the day, users’ electric vehicles can be directly charged using photovoltaic power generation, and at night they are powered by energy storage systems, thus realizing an all-weather green charging solution. This not only improves the energy efficiency of electric vehicles but also reduces dependence on traditional fossil energy, further promoting the popularization of green travel.
Reliability and redundancy design
The system has a redundant design to ensure that when a certain link fails, other parts can continue to operate stably. For example, when photovoltaic power generation is insufficient or the power grid fails, the energy storage system can be used as a backup power supply to maintain the normal operation of the EV charger. Through intelligent management, the system can quickly detect and isolate the faulty module to ensure the stability and reliability of the overall operation of the system.
System collaborative management: Energy Management System (EMS)
EMS is responsible for the intelligent scheduling of the entire system, balancing photovoltaic power generation, energy storage charging and discharging, and electric vehicle charging needs, achieving dynamic optimization and load balancing, and avoiding energy waste. The system integrates real-time data collection functions, which can analyze energy usage patterns, vehicle charging needs, and photovoltaic power generation, and provide data support for subsequent system optimization. EMS has energy demand forecasting functions, based on weather forecasts, historical data and real-time information, predicts future photovoltaic power generation and energy storage needs, and optimizes power dispatching.
Economic benefits and sustainable development
SCU’s solar energy storage EV charger integrated system brings significant economic benefits and sustainable development advantages to users. First, by making rational use of the difference in peak and valley electricity prices, users can effectively reduce electricity costs. Secondly, through intelligent regulation, the system optimizes the utilization rate of self-generated electricity, and reduces dependence on the power grid, thereby reducing carbon emissions and achieving environmental protection goals. In addition, the system’s energy storage scheduling function provides users with sufficient backup power to ensure the continuity and reliability of electric vehicle charging.
Outlook
The solar energy storage EV charger integrated system successfully built by SCU for German users not only demonstrates SCU’s technical strength and innovation capabilities in the field of renewable energy, but also provides an excellent demonstration case for the transformation of the global energy structure. In the future, SCU will continue to be committed to providing global users with efficient, stable and green energy solutions, promoting the deep integration of photovoltaics, energy storage and electric vehicle charging, and helping the world move toward the goal of sustainable development.
