Application scenarios

  1. Power Grid Peak Regulation and Frequency Modulation

    Adaptation Advantages: A capacity of 3.44MWh can meet the daily peak regulation demand of 15,000 households; liquid cooling technology supports 24-hour continuous charging and discharging, with a response time to grid dispatching instructions of <100ms, helping the power grid meet frequency modulation standards (in line with GB/T 36547 power grid standards); covering "3.44MWh energy storage for power grid peak regulation" and "large-scale BESS for power grid frequency modulation".

  2. New Energy Power Station Absorption

    Adaptation Advantages: It can be linked with 100MW-level photovoltaic/wind farms to store intermittent electric energy and increase the new energy absorption rate by 20%; the 20-foot container design shortens the deployment cycle to 15 days, adapting to the needs of rapid grid connection of power stations; covering "3.44MWh energy storage supporting photovoltaic power stations" and "large-scale energy storage systems for wind farms".

  3. Regional Power Grid Backup Power Supply

     Adaptation Advantages: IP54 protection and (-20℃~50℃) temperature resistance, suitable for outdoor substation deployment; 3.44MWh capacity can support emergency power supply for key loads of regional power grids (such as hospitals, transportation hubs) for 8-10 hours, avoiding large-scale power outages caused by power grid failures; covering "regional power grid backup energy storage" and "large-scale emergency energy storage systems".

 

 

FAQ
Q: What is air cooling?
A:

The basic principle of air cooling technology is to take away the heat generated by battery cells through flowing air, thus keeping the battery temperature within a reasonable range. As a heat transfer medium, air can achieve heat exchange through natural convection or forced convection.

  • Natural convection:Natural convection refers to the phenomenon in which air flows by itself due to the difference in air density caused by temperature differences.In some cases, natural convection can be used to achieve simple thermal management, but this is usually not sufficient to meet high-intensity or high-density energy storage requirements.

  • Forced convection:Forced convection is to accelerate air flow through fans or other mechanical devices, thereby improving heat exchange efficiency.In container energy storage systems, forced convection is usually used to achieve effective thermal management.
