Briefly describe the difference between power lithium batteries and energy storage batteries

1. The voltage is different. In the battery industry, the voltage increases, and the corresponding output voltage will also increase, so that the power-type lithium-ion battery pack can meet some high-power equipment; the result of the direct effect of the parallel connection is The current of the entire battery pack increases, and the capacity is affected by the current at the output end, so the direct use of parallel connection is to increase the capacity of the lithium-ion battery pack. The capacity of the battery pack connected in this way tends to be relatively large. This is the so-called capacity type lithium-ion battery pack. Power lithium batteries are mainly used for energy storage, with large capacity requirements, long life requirements, and low self-discharge. The capacity of power tool batteries is not large, and do not provide high-power output; while energy storage batteries are mainly used for power supply and require high-power output. 2. Different products are used. Some large-scale equipment requires higher voltage values u200bu200bbecause of low power. The battery pack can not run with the battery, so it is necessary to choose the power type lithium-ion battery pack. For example, for the electric bicycles we usually use, the required voltage value is often 48V. Compared with some situations in our lives, 48V is not small. Therefore, it is necessary to use power-type lithium-ion battery packs to ensure the operation of electric bicycles. And we usually go to some large supermarkets or shopping malls, some sign lights and backup power supplies. Because these devices do not consume a lot of power, they generally use capacity-type lithium-ion battery packs. The difference between the two is in product application. different. The lithium-ion batteries used in BYD electric cars and new energy vehicles are all power lithium-ion batteries, which are divided into power type, energy type and power-energy type according to their characteristics. The power type is the important feature of the power lithium-ion battery you are talking about. It supports high-rate charge and discharge, which is generally as high as 10C or more. The important parameter to consider is the specific function (W/kg). The important characteristic of energy type is higher specific energy (Wh/kg). For example, the capacity type is a marathon runner. To have endurance, it means that the capacity is large, and the requirements for high-current discharge performance are generally not high; the power type is a sprinter who fights for bursting power, but also has endurance, otherwise the capacity is too large. You can't run far when you are young. Disclaimer: Some pictures and content of articles published on this site are from the Internet. If there is any infringement, please contact to delete.
