Do you remember the beginner-level energy storage terminology we shared last week? In this week's article, you can learn more professional terms. Let's take a look at what new knowledge we have this time. 

1. C-rate:Battery charge and discharge rate indicator, e.g., 1C means fully charged/discharged in 1 hour. Excessively high rates accelerate battery aging.

2. SOH (State of Health):Measures the current performance of the battery relative to its factory state, reflecting the degree of aging. 

3. EMS (Energy Management System):manages and optimizes the scheduling of photovoltaic, energy storage batteries, and the power grid, achieving intelligent control and improved energy efficiency.

4. PCS (Power Conversion System):The power conversion equipment in the energy storage system, performing bidirectional inverter control.

5. Parallel Balancing (Passive/Active Balancing):Balances the voltage differences between individual cells within a battery pack to prevent overcharging/under-voltage.

6. Thermal Management System: controls the cell temperature through air cooling/liquid cooling methods to prevent thermal runaway. 

7. BESS (Battery Energy Storage System) is a general term for battery energy storage systems, including battery cells, inverters, control systems, and more.

8. High Voltage Direct Current System (HVDC): Energy storage integrated system suitable for high-capacity transmission, improving efficiency and reducing losses.

9. Latency: The delay time from the energy storage system recognizing a signal to actually supplying power, affecting the effectiveness of emergency backup.

10. Cell-Module-Cluster-System: The structural hierarchy of energy storage batteries, from individual cells to the complete system. 

11. Thermal Runaway: An abnormal rise in cell temperature → a chain reaction of escalating reactions leading to further temperature increase.

12. V2H/V2G (Vehicle to Home/Grid): Technology route for electric vehicle batteries to supply power back to homes or the grid.

13. Electro-chemical Storage: The most common type of energy storage, including lithium-ion, lead-acid, sodium-ion, etc.

14. Solid-state Battery: The future trend in energy storage, with solid electrolytes; safer but more expensive.

15. Fire Class/UL9540A: Fire safety certification for energy storage systems, determining whether they can be installed in residential areas.

16. Black Start Capability: The ability to start supplying power independently without external power, suitable for restarting after a blackout.

17. Hybrid Inverter: A dual-input inverter supporting both photovoltaic input and battery storage, integrated design convenient for home use.

18. Smart Dispatching: Automatically scheduling charging and discharging plans based on peak and off-peak electricity prices/load forecasts to achieve energy savings and cost reduction.

19. Insulation Monitoring: A key safety indicator to detect potential leakage risks in high-voltage systems. 

20. System Integration Level: Measures the coordinated control capability of various system modules, significantly affecting operational stability in the later stage.
