They store excess energy generated during peak production times for use during high-demand periods. In China, the top BESS integrators include notable companies such as CRRC Zhuzhou Electric Locomotive Research Institute and Sungrow Power Supply, which have made significant contributions to the industry.

Technical Features of BESS

Feature	Description
Capacity	The amount of energy the system can store, typically measured in kilowatt-hours (kWh) or megawatt-hours (MWh).
Discharge Duration	The length of time the system can supply energy at rated power, often expressed in hours.
Efficiency	The ratio of energy output to energy input, indicating how much energy is retained after storage.
Chemistry	Common chemistries include lithium-ion, lead-acid, and flow batteries, each with unique performance characteristics.
Scalability	The ability to expand the system’s capacity by adding more units without significant redesign.

Exploring Battery Management Systems (BMS)

Battery management systems (BMS) are critical for monitoring and managing rechargeable batteries within energy storage systems. They ensure optimal performance, safety, and longevity of the battery packs. The market for BMS in China is expanding rapidly, driven by the increasing demand for electric vehicles and renewable energy storage solutions.

Technical Features of BMS

Feature	Description
Monitoring	Real-time tracking of voltage, current, and temperature of individual cells within the battery pack.
Balancing	Ensures all cells within a battery pack charge and discharge evenly to prolong battery life.
Protection	Prevents overcharging, over-discharging, and short-circuiting to enhance safety.
Communication	Interfaces with external systems to relay data and receive commands, often using protocols like CAN or RS485.
Integration	BMS can be integrated into battery packs, allowing for compact designs that save space and weight.

Types of Battery Systems

Battery systems can be categorized based on their application and chemistry. Below are the primary types of battery systems utilized in China:

Comparison of Battery Types

Type	Description
