Why Are Vehicle Charging Station Inseparable From Energy Storage System?
With growing global environmental awareness and the rapid development of the electric vehicle industry, new energy vehicles are gradually becoming a mainstream means of transportation. As critical infrastructure to ensure the normal operation of new energy vehicles, charging stations are becoming increasingly important. In their daily operations, charging stations often face real challenges such as power supply fluctuations and high electricity prices. To address these challenges, the introduction of energy storage systems is becoming a key means for charging stations to improve operational efficiency, control costs, and enhance stability.
Charging peaks place a burden on the power grid; energy storage mitigates power surges.
When multiple new energy vehicles are connected to fast charging equipment simultaneously, charging power fluctuates significantly and instantaneously, placing significant pressure on the power grid. For example, a station equipped with 20 fast charging stations, each with a power of 120KW, and just 10 vehicles charging simultaneously could generate a transient load of up to 1200KW. This sudden load can easily cause voltage fluctuations and frequency anomalies, and even threaten power supply security.
Xindun's lithium battery energy storage system can be flexibly deployed in various commercial and public charging stations. The Xindun energy storage system boasts millisecond level response capabilities, rapidly discharging to share the load during peak charging power levels and reversely charging to store energy during low load periods. This ensures stable and smooth power output at charging stations, extending equipment life and guaranteeing safe grid operation.
Energy Storage Systems: The "Energy Regulator" of Charging Stations
Modern energy storage system, comprised of battery modules, bidirectional converters, and an intelligent control platform, can flexibly respond to fluctuating charging loads. When a charging station enters a high load operating state, the energy storage unit rapidly replenishes power, reducing reliance on utility power. During periods of low charging demand, the system utilizes excess grid power for charging, preparing for the next peak period.
This "peak shaving and valley filling" operation smoothes the charging station's power curve and avoids high frequency shocks to the grid and equipment. Data shows that stations equipped with energy storage can reduce power fluctuations by over 50%, effectively ensuring power supply system stability and equipment safety.
Utilizing time of use electricity pricing, energy storage helps reduce costs and increase efficiency.
Currently, most regions in China have implemented a time of use electricity pricing system: electricity prices are higher during peak hours and relatively cheaper during off peak hours. Energy storage systems can take advantage of these price differences, charging when prices are low and discharging when prices are high, thereby optimizing electricity costs.
Based on daily average discharge For example, with a 500 kWh electricity consumption and a 0.8 yuan difference between peak and off peak electricity prices, the Xindun energy storage system can save 400 yuan in electricity bills per day, or over 10,000 yuan per month. For operators, this means lower operating expenses and higher profit margins; for users, it offers the opportunity to enjoy more affordable charging prices, increasing station loyalty and frequency of use.
Enhancing User Experience and Boosting Competitiveness
In the increasingly competitive charging market, charging stations equipped with energy storage systems are particularly attractive to users. They offer more stable charging capabilities, lower service prices, and faster response times, effectively reducing queues and improving overall service quality, especially during peak electricity consumption periods such as holidays and rush hours.
Stations equipped with energy storage also have the opportunity to participate in power ancillary services such as peak shaving, frequency regulation, and backup power, providing valuable services to the grid and generating additional revenue. This diversified profit model not only broadens revenue channels but also enhances companies' ability to adapt to changes in the electricity market.
