What is the difference between energy storage battery and power battery

　　1、 The operating voltage varies.

　　The lithium battery production company found that in the battery production field, when the operating voltage increases, the relative output voltage also increases, so that the power lithium ion battery pack can consider some mechanical equipment with higher power; The direct harm of the series connection method is to advance the current of the full battery pack, which endangers the capacity. Current appears, so the immediate effect of the series connection is to let the lithium ion battery work. With the advance of capacity, the capacity of batteries connected by this method will become larger, which is called capacity lithium ion battery.

　　The power battery is a key technology for energy storage. Its capacity is regular, its service life is regular, and its lithium ion battery life is short. When using pneumatic tools, the battery is small. Do not show power output, but show power output.

　　2、 The materials used are different.

　　The operating voltage of some large and medium-sized mechanical equipment is relatively high. Since small power batteries cannot operate normally, power lithium ion batteries need to be selected. For example, the electric cars widely used by us generally need 48V operating voltage. Compared with some situations in our daily life, the 48V value is quite large. Therefore, power lithium-ion batteries must be used to ensure the operation of electric cars. Everyone usually goes to some large shopping malls or shopping malls, some indicator lights and backup power supplies. Because the power consumption of this kind of machinery and equipment is not very large, everyone generally uses the bulk lithium ion battery, which is different in product application.

　　The power lithium battery is a lithium-ion battery used in BYD sedan powered trams and new power vehicles. It can be divided into three types according to its characteristics: switching power supply type, electric power type, switching power supply type and electric power type. The important feature of power lithium-ion battery is that it is suitable for charging polymer cells, generally up to 10C, and the basic parameters are special for use (W/kg). The important feature of such kinetic energy is its high energy density (WH/kg). For example, the volume type is a marathon runner, which requires a certain amount of physical strength, that is, large volume, and generally does not use the charging and discharging characteristics of large current; The output type is the weight lifter, who must have a certain amount of physical strength, otherwise the size is small and the running is very close.

　　What is the difference between hard pack lithium battery and soft pack lithium battery

　　Soft shell lithium-ion batteries are 40% and 20% lighter than steel shell and aluminum shell lithium-ion batteries. In terms of weight, soft lithium-ion battery is much lighter than hard lithium-ion battery, but the proportion of important weight still depends on the weight of the box.

　　Soft packed lithium ion batteries are 10% to 15% higher than steel and aluminum batteries, and 5% to 10% higher than steel and aluminum batteries. Although the capacity of soft package lithium-ion battery is not much higher than that of hard package lithium-ion battery, there is still a gap between them. In regions with high capacity requirements, the use of soft package lithium-ion batteries is still higher than that of hard package lithium-ion batteries.

　　As the internal battery of soft lithium-ion battery is liquid, its shape can generally have a variety of shapes, which has great advantages over hard lithium-ion battery in the field of specific requirements for the shape of lithium-ion battery.
