1、 The battery capacity of energy storage container and battery is different
In the case of all new batteries, test the battery capacity with a discharge meter. Generally, the capacity of power lithium battery is about 1000-1500mAh; The capacity of lithium battery pack for energy storage is more than 2000mAh, and some can reach 3400mAh.
2、 The application industries of energy storage containers and batteries are different
Power lithium battery is used for driving power supply of electric vehicles, electric bicycles, electric motorcycles, electric equipment and tools; It is used for transmission and transformation power stations and provides closing current for power units; Lithium battery packs for energy storage are mainly used in hydropower, thermal, wind and solar power stations and other energy storage power stations, peak shaving and frequency modulation power auxiliary services, digital products, power products, medical and security, and UPS power supplies.
3、 The BMS position of the energy storage container and the energy storage battery is different
In the energy storage system, the lithium energy storage battery only interacts with the energy storage converter at high voltage, and the converter takes power from the AC power grid to charge the battery pack; Or the battery pack supplies power to the converter, and the electric energy is converted into AC through the converter and sent to the AC power grid; The BMS of electric vehicles has an energy exchange relationship with motors and chargers at high voltage; In terms of communication, there is information interaction with the charger during the charging process. In all application processes, there is the most detailed information interaction with the vehicle controller.
4、 Different types of cells are used for energy storage containers and energy storage batteries
Considering the safety and economy, lithium iron phosphate batteries are often used when selecting lithium battery packs for energy storage power stations, and lead acid batteries and lead carbon batteries are more often used in energy storage power stations; The current mainstream battery types of power lithium battery electric vehicles are lithium iron phosphate battery and lithium ternary battery.
5、 The performance and design of energy storage container and battery are different
Power lithium battery is more focused on charging and discharging power and other aspects, requiring fast charging rate, high output power and vibration resistance, especially high safety and high energy density, which have reached the endurance capacity, as well as lightweight requirements in weight and volume; The preparation of lithium energy storage battery emphasizes the battery capacity, especially the operation stability and service life. More consideration should be given to the consistency of battery modules. In terms of battery materials, attention should be paid to the expansion rate and energy density, and the performance uniformity of electrode materials, in order to pursue the long life and low cost of the overall energy storage equipment.
6、 The nature of energy storage container is different from that of energy storage battery
Power lithium battery refers to the battery that provides power for transportation vehicles, generally compared with small battery that provides energy for portable electronic equipment; The ordinary energy storage lithium battery is a kind of primary battery which uses lithium metal or lithium alloy as the anode material and uses non-aqueous electrolyte solution. It is different from rechargeable lithium ion battery and lithium ion polymer battery.
With the extensive application of the container project of energy storage power station in new energy power generation, grid side, industrial and commercial user side, electric auxiliary services, microgrid, optical storage charging station, energy internet, smart energy, data center, energy-saving transformation, shore power transformation and other fields, and the scale of the container power station of energy storage power station is gradually promoted to megawatt level, tens of megawatt level and even hundreds of megawatt level, It marks a key step in the application of lithium battery energy storage power station container system in the field of grid side. With the continuous breakthrough of lithium battery technology in the future, the cost of energy-storage containers is expected to be significantly reduced, and the prospect is worth looking forward to.
