Three Core Knowledge Areas You Must Master

Area 1: Technical Route and Core Components (Understanding the Structure of an Energy Storage System)

An energy storage system (especially electrochemical energy storage) is like a person:

Cell -> Heart: The core unit that stores energy. Currently, the mainstream is the LFP battery due to its safety and long lifespan.

Battery Pack -> Body: Made up of many cells, plus structural components and heat sinks.

BMS -> Brain: Constantly monitors the health of each cell (voltage, temperature), preventing overcharge and over-discharge to ensure safety.

EMS -> Commander-in-Chief: Responsible for formulating economic strategies. It knows when to charge when electricity prices are low and when to discharge when prices are high, maximizing profits.

PCS -> Muscle/Converter: Responsible for converting between AC (grid power) and DC (battery power), controlling charging and discharging.

Area 2 : Main Application Scenarios (Where is energy storage used?)

Generation Side:

Renewable Energy Storage: Energy storage is installed alongside wind farms and photovoltaic power plants.

Grid Side: Power grid companies construct storage systems for peak shaving and frequency regulation, maintaining grid stability.

User Side - This is currently the most mainstream application:

Commercial and Industrial Energy Storage: Factories, shopping malls, etc., install energy storage primarily to save huge amounts of money on electricity bills by taking advantage of peak-valley price differences.

Residential Energy Storage: Combined with rooftop photovoltaic systems, it enables households to achieve self-sufficiency in electricity.

Area 3: Safety – The Absolute Red Line

Thermal Runaway: This is the greatest threat to battery safety. It refers to the phenomenon where a battery's temperature rises cascadingly due to short circuits, overheating, or other reasons, ultimately leading to fire and explosion.

Safety Design: Excellent energy storage systems prevent and mitigate thermal runaway through multiple aspects, including cell selection (LFP is safer), real-time BMS monitoring, fire suppression systems (fire extinguishing gases such as heptafluoropropane), and structural design.
