The difference between industrial batteries and energy storage batteries.
2025-02-13
The main differences between industrial batteries and energy storage batteries lie in their application scenarios, technical requirements, and system composition.
Application Scenarios
Energy Storage Batteries: Widely used in grid energy storage, home energy storage, commercial and industrial energy storage, communication base stations, and other fields. The design of energy storage batteries is mainly optimized for energy density and long-term storage to meet the needs for large capacity and durable energy storage. Since energy storage devices usually do not need to be moved, there is no direct demand for energy density, but there are different requirements for power density.
Industrial Batteries: Mainly used in the transportation-related industries such as new energy passenger vehicles and commercial vehicles. Industrial batteries focus more on power density and high power output in a short time to meet the needs for rapid acceleration and long mileage in electric vehicles.
Technical Requirements
Energy Storage Batteries: In terms of battery technology, commercial and industrial energy storage typically uses energy-type batteries, which have relatively low requirements for response time and simpler system functions. The Battery Management System (BMS) provides basic protection functions and voltage balancing, and parameters can be configured and data monitored through backend software.
Industrial Batteries: The power battery system is on high-speed moving electric vehicles, requiring higher demands for battery power response speed, power characteristics, and the number of state parameter calculations. The BMS needs to achieve higher regulation functions to ensure that the battery pack safely and reliably provides power output for electric vehicles.
System Composition
Energy Storage Battery System: Mainly composed of battery packs, BMS, EMS (Energy Management System), PCS (Energy Storage Inverter), and other electrical equipment. In terms of cost composition, the battery is the main part, accounting for 60%; followed by the inverter, accounting for 20%; EMS accounts for 10%; BMS accounts for 5%; and others account for 5%.
Industrial Battery System: The PACK (battery module, battery management system, thermal management system, electrical system, and structural system) cost is composed of comprehensive costs including cells, structural parts, BMS, enclosures, auxiliary materials, and manufacturing costs, with cells accounting for about 80% of the cost, and PACK costs accounting for about 20% of the total battery cost.
Cost Composition
Energy Storage Battery System: The cost is mainly composed of batteries, inverters, and EMS, with batteries having the largest share (60%), followed by inverters (20%), EMS (10%), BMS (5%), and others (5%).
Industrial Battery System: Cells account for about 80% of the cost, and PACK costs account for about 20% of the total battery cost.
