Technical parameter
Application scenarios
Peak-shaving and valley-filling for industrial and commercial use
Value points: Large capacity of 232kWh, which can store electricity at night when electricity prices are low and release it during peak hours in the daytime, reducing enterprises' electricity expenses (with a price difference of 0.5 yuan per kWh, the annual electricity cost saving is about 100,000 yuan); box-type integrated design, no debugging required, deployment can be completed in 3 days, without affecting factory production.
Emergency backup power supply on the grid side
Value points: Supports off-grid switching within 10 seconds (referring to the technology of the same brand), 107kWh capacity can support emergency power supply for key equipment in substations and data centers for 4-6 hours; IP54 protection (speculated to be the standard of the same brand), strong weather resistance for outdoor deployment, coping with extreme weather such as heavy rain and high temperature.
Supporting integration of wind, solar and storage
Value points: Can be linked with 10MW-level photovoltaic/wind farms to store intermittent wind and solar energy and stabilize output fluctuations; modular design supports parallel connection of multiple units (for example, 2 units of 232kWh can meet the demand of 464kWh), adapting to the capacity expansion of new energy projects.
Identify short-circuit situations.
-
Current detection:The BMS identifies short-circuit conditions by continuously monitoring the current changes of the battery pack. When an abnormally high current is detected, a short circuit may have occurred.
-
Voltage monitoring:In the case of a short circuit, the voltage of the affected battery cell or the entire battery pack may suddenly drop. The BMS identifies this abnormal situation through vltage monitoring.
-
Temperature monitoring:A short circuit will cause a sharp rise in local temperature. The BMS detects abnormal temperature rises through temperature sensors to determine whether a short circuit has occurred.
Implement protection measures.
-
Cut off power supply:When a short circuit is detected, the BMS will immediately cut off the connection between the battery pack and the external circuit through relays or switches to prevent the current from continuing to flow and avoid excessive discharge or heating of the battery.
-
Alarm and record:Trigger the alarm system to send a warning signal to the operator and record relevant information such as the time and location of the short circuit occurrence for subsequent investigation and handling.
-
Isolate faulty units:If the short circuit occurs in a certain battery cell rather than the entire battery pack, the BMS can isolate the cell to prevent it from affecting other normal battery cells.
