1 INTRODUCTION. Recently, the lithium-breed batteries gradually replace other types of batteries due to their advantages of higher voltage level, long service life, nontoxic and no pollution, and are widespread exist in a variety of hand-held electronics [1-5].As discussed in [3, 6-15], lithium batteries can be damaged by many conditions, such as excessively high or low
Open Circuit Voltage (OCV). They deliver about 3.3V to 3.4V Closed Circuit Voltage (CCV) at nominal currents. So to get higher voltages, configure a series of cells connected positive to negative and so forth. Each cell step in the series contributes about 3.6V OCV to the battery pack (see figures 4 and 5). This is achieved by loading batteries
Hence, most battery pack sizing studies start with the Energy, Power and Working Voltage Range (Inputs to Pack Sizing is a more complete list). The operating voltage of the pack is fundamentally determined by the cell
Whenever possible, using a single string of lithium cells is usually the preferred configuration for a lithium ion battery pack as it is the lowest cost and simplest. However, sometimes it may be necessary to use multiple strings of cells. Here are a few reasons that parallel strings may be necessary:
Therefore, the lithium battery must also be about 58v, so it must be 14 strings to 58.8v, 14 times 4.2, and the iron-lithium full charge is about 3.4v, it must be four strings of 12v, 48v must be 16 strings, and so on, 60v There must be 20 strings in parallel with the same model and the same capacity.
The operating voltage of the pack is fundamentally determined by the cell chemistry and the number of cells joined in series. If there is a requirement to deliver a minimum battery pack capacity (eg Electric Vehicle) then you need to understand the variability in cell capacity and how that impacts pack configuration.
If each cell is 10 amp hours and 3.3 volts, the battery pack above would be 10 amp hours and 26.4 volts (3.3 volts x 8 cells). For this setup, a BMS capable of monitoring 8 cells in series is necessary. Lithium cells can almost always be paralleled directly together to essentially create a larger cell.
Different voltage sizes of lithium-ion batteries are available, such as 12V, 24V, and 48V. The lithium-ion battery voltage chart lets you determine the discharge chart for each battery and charge them safely. Here is 12V, 24V, and 48V battery voltage chart:
However, all of this takes time and hence please use this as a first approximation. The battery pack mass is roughly 1.6x the cell mass, based on benchmarking data from >160 packs. However, there are a number of estimation options and always the fallback will be to list and weigh all of the components.
