The differences and connections between power batteries and energy storage batteries
Due to different application scenarios, the performance requirements of the battery are also different. Most of the energy storage devices do not need to move, so the energy storage lithium battery does not have a direct requirement for energy density. Compared with power lithium batteries, energy storage lithium batteries have higher requirements for service life. In terms of cost, power lithium batteries face competition with traditional fuel power sources, and energy storage lithium batteries need to face the cost competition of traditional peak adjustment and frequency adjustment technology. The battery is used to store electricity. In terms of application, it is energy storage. Therefore, it can be said that all lithium batteries are energy storage batteries. Later, in order to distinguish applications, it is divided into consumer batteries, power batteries, and energy storage batteries. Three types. Consumer applications are consumer products such as mobile phones, laptops, and digital cameras. Power applications are applied to electric vehicles, and energy storage applications are applied to energy storage power stations.

Power batteries are actually a type of energy storage battery. They are mainly used in electric vehicles. Due to the volume and weight of the car, and the requirements for starting acceleration, power batteries have higher performance than ordinary energy storage batteries than ordinary energy storage batteries. It is required that if the energy density should be as high as possible, the charging speed of the battery should be fast, and the discharge current must be large, but the requirements of ordinary energy storage batteries are not so high. According to the standard, the capacity of the power battery cannot be used in new energy. The car, but a slight transformation, can be used in the energy storage system.
From the perspective of application scenarios, power lithium batteries are mainly used in electric vehicles, electric bicycles, and other electric tools. The energy storage lithium battery is mainly used for peak -regulating frequency and frequency power auxiliary services, renewable energy grids and networking and networking. Micro grids and other fields.
Due to the different application scenarios, the performance requirements of the battery are also different. First of all, as a mobile power supply, the power lithium battery is as high as possible under the premise of safety (and quality) energy density as much as possible in order to achieve a longer -lasting battery life. At the same time, users also hope that electric vehicles can be safely charged. Therefore, power lithium batteries have high requirements for energy density and power density. It is only because of safety considerations, energy batteries that are generally used at about 1C.
Most of the energy storage devices do not need to move, so the energy storage lithium battery does not have a direct requirement for energy density. As for power density, different energy storage scenarios have different requirements.
It is used for power -based peak adjustment, network -type photovoltaic energy storage or user -side peak valley price difference energy storage scenarios. Generally, energy storage batteries are required continuousCharging or continuous discharge for more than two hours, so it is suitable for using a capacity battery of 0.5C; for the energy storage scenarios of power frequency adjustment or smooth renewable energy fluctuations, energy storage batteries require energy storage batteries from seconds to minute -level time. The section is quickly charged and discharged, so it is suitable for the application of the 2C power battery; and in some application scenarios that need to be responsible for frequency adjustment and peak adjustment at the same time, energy batteries will be more suitable. Of course, in this scenario Use capacity batteries together.
Compared with power lithium batteries, energy storage lithium batteries have higher requirements for service life. The life of new energy vehicles is generally 5-8 years, while the life span of energy storage projects generally wants to be greater than 10 years. The number of cycles of power lithium batteries is 1,000-2000 times, while the number of cycles of energy storage lithium batteries generally requires greater than 3500 times.
In terms of cost, power lithium batteries face competition with traditional fuel power sources, and energy storage lithium batteries need to face the cost competition of traditional peak adjustment and frequency adjustment technology. In addition, the scale of energy storage power stations is basically the level of MGV level or even a hundred MW. Therefore, the cost of energy storage lithium batteries is lower than the cost of power lithium batteries and higher safety requirements.
There are some differences between power lithium batteries and energy storage lithium batteries, but from the perspective of the battery cells, they are the same. They can use lithium iron phosphate batteries and ternary lithium batteries. The main difference is that the BMS battery management system can be used. The power response speed and power characteristics of the battery, the SOC estimation accuracy, the charging and discharge characteristics, etc., can be implemented on the BMS.
