For power batteries, it is actually a type of energy storage battery.However, due to the volume and weight restrictions of the car and the acceleration requirements at startup, power batteries have higher performance requirements than ordinary energy storage batteries. For example, the energy density must be as high as possible, the battery charging speed must be fast, and the discharge current must be large. wait.According to standards, power batteries with a capacity below 80% can no longer be used in new energy vehicles.For energy storage batteries, most energy storage devices do not need to be moved, so energy storage lithium batteries have no direct requirements for energy density.As for power density, different energy storage scenarios have different requirements.There are some differences between power lithium batteries and energy storage lithium batteries, but in terms of battery cells, they are all the same. Both lithium iron phosphate batteries and ternary lithium batteries can be used. The main difference lies in the BMS battery management system and the power response speed of the battery. And power characteristics, SOC estimation accuracy, charge and discharge characteristics, etc. can all be realized on BMS.
