What are the differences between lithium-ion battery power lithium battery and energy storage technology battery?

1. The size of the working voltage is different. Lithium-ion battery manufacturing companies have found that in the battery field, when the working voltage rises, the relative output voltage will also rise, so that power lithium-ion battery packs can consider some high-power machinery and equipment; The immediate hazard of the series method is to increase the current capacity of all battery packs, and the volume is affected by it. E output current, so the immediate effect of series connection is to make lithium-ion battery packs. With the increase in volume, the volume of the battery connected in this way tends to be larger, that is, the blunt volume lithium-ion battery. Power lithium batteries are mainly used for energy storage technology, with large volume requirements, long service life, and low lifespan of lithium ion batteries. The battery for pneumatic tools has a small volume and does not need to show a high-power output, while the battery is key to show power and must have a high-power output. 2. The products used are not the same. Some large and medium-sized machinery and equipment must have a higher working voltage value. Since low-output batteries cannot work, power lithium-ion batteries are selected. For example, people generally use electric vehicles, and generally require a working voltage of 48V. Compared with some situations in your daily life, 48V is not very large. Therefore, power lithium-ion batteries must be used to ensure the operation of electric vehicles. People usually go to some large shopping malls or shopping malls, some sign lights and backup power sources. Since the power consumption of this kind of machinery and equipment is not very large, so people generally use lithium-ion batteries, which are different in the use of goods. of. The lithium-ion batteries used in BYD's electric trams and new energy vehicles are power lithium batteries, which are divided into three types according to their characteristics: switching power supply types, electric energy types, and switching power supply and electric energy types. The important feature of power lithium-ion battery is that it is suitable for battery charging with polymer cells, generally reaching 10C, and the basic parameter is special purpose (W/kg). The key feature of the kinetic energy category is the high energy density (WH/kg). For example, the volume type is a marathon runner who must have physical strength, that is, a large volume, and generally does not require high current charge and discharge characteristics; the output power type is a weightlifter, fighting for an outbreak, but also physical strength, otherwise the volume is small and running very close. 3. The internal resistance is different. The internal resistance of the power lithium-ion battery is smaller than that of the large-volume lithium-ion battery. Taking 18650 as an example, manufacturers with good 3-times charge-discharge rates generally have PDC with an internal resistance of about 40, and manufacturers with 5 times charge-discharge rates generally do not have PDC internal resistance of about 20%.
