The differences between power lithium-ion batteries and energy storage batteries are as follows:

Different application fields: Power lithium-ion batteries are mainly used in electric vehicles, electric bicycles, and other electric tools, while energy storage batteries are mainly used in peak shaving and frequency modulation power auxiliary services, renewable energy grid connection, and microgrids.

The battery management system is different: the power lithium battery system is located in high-speed electric vehicles, and has higher requirements for the power response speed and power characteristics of the battery, SOC estimation accuracy, and the number of state parameter calculations. Generally, there is only one centralized or two distributed layer; The scale of energy storage battery systems is relatively large, and the hardware generally adopts a two-layer or three-layer mode. Larger systems tend to have a three-layer management system.

Cost difference: Power lithium-ion batteries face competition from traditional fuel power sources, while energy storage batteries face cost competition from traditional peak shaving and frequency modulation technologies
