Charging Station
As the adoption of electric vehicles (EVs) continues to rise in Germany, the demand for fast charging infrastructure is also growing. To meet the needs of long-distance drivers, there are plans to establish an advanced fast-charging station along the highways in Germany. This station will be equipped with four high-performance fast chargers, each with an output power of 240 kW. The goal is to provide rapid and efficient charging services, reduce charging wait times, and enhance the user experience.
Project Overview
Available Only Through Renon Power
Local Situation
Charging Station Power Supply Challenges
The existing power grid infrastructure limits the ability to supply power directly. According to the assessment, the maximum power supply capacity of the grid at this location is 400 kW, which is far below the 960 kW total power required for the simultaneous operation of four fast-charging units. Upgrading or modifying the grid to increase its power supply capacity is an expensive and time-consuming project that involves complex planning and approval processes, resulting in high costs.
Battery Energy Storage Solution
Achieving Efficient Charging Services and Addressing Grid Power Supply Bottlenecks
To overcome the local power supply limitations and avoid the high costs of upgrading the grid, the project has decided to use a Battery Energy Storage System (BESS) as a buffer. The system will charge the batteries using the surplus capacity of the grid during off-peak hours. During peak hours, when vehicle charging demand is high, the batteries will support the grid to ensure that the charging units can continuously provide 240 kW of power output.

Core Component Selection
Renon Power Specialization
Battery System Selection
Selection: 8 x 240kWh Lithium Battery Energy Storage Systems
Rationale: Each energy storage system has a capacity of 240kWh. To meet the total requirement of 1680kWh during 3 hours of peak demand (accounting for efficiency losses), we selected eight systems, totaling 1920kWh. This larger capacity ensures redundancy and stable operation, providing sufficient backup even during high-demand periods.
Charging Power: Each system has a charging power of 125kW, enabling the grid to charge the batteries quickly during off-peak hours and ensuring they can deliver adequate auxiliary power during peak times.
Advantages: Lithium batteries are ideal for this application due to their high energy density, long cycle life, and rapid response capabilities. They can endure frequent charge and discharge cycles, ensuring long-term stability and efficiency in high-demand situations.
PCS (Power Conversion System) Power Configuration
Rationale: The Power Conversion System (PCS) is a critical component connecting the batteries to the grid, responsible for regulating current and voltage during charging and discharging. Given that each energy storage system has a charging power of 125kW, the PCS power configuration must match this capacity to ensure overall system stability and efficiency. This ensures that both the charging and discharging processes are conducted efficiently and safely.
Advantages: Advanced PCS units provide bidirectional power flow, maintaining high efficiency during charging and precisely controlling output during discharging. This ensures smooth energy exchange between the grid and the batteries, enhancing system performance and stability.
Fast Charging Stations
Selection: 125kW Fast Charging Stations
Configuration: Each Estand integrated unit includes a 240kW dual-gun charging station, allowing a single charger to simultaneously provide fast charging for two electric vehicles.
Advantages: The high power output significantly reduces charging times, enhancing the user experience. The dual-gun design improves the utilization rate of the charging station, minimizing wait times for users.
This solution integrates a battery energy storage system that intelligently absorbs energy from the grid and solar system during off-peak hours, storing it for use during peak demand periods. This approach effectively smooths the power demand curve, reducing instantaneous power demand on the grid.
