What are the characteristics of a battery pack?
Part 4. Voltage and capacity Voltage and capacity are fundamental characteristics of any battery pack. In Li-ion batteries, the voltage per cell usually ranges from 3.6V to 3.7V. By connecting cells in series, you can increase the overall voltage of the battery pack to meet specific needs.
What determines the operating voltage of a battery pack?
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.
What is battery capacity?
So, let’s start learning about the very important concept of “Battery Capacity”. Battery Capacity is defined as the product of the electric current flowing in or out of the battery in amperes and the time duration expressed in hours. Battery Capacity influences the time for which a device can operate without using power from any other sources.
What is the difference between battery capacity and chemical capacity?
The battery capacity is the current capacity of the battery and is expressed in Ampere-hours, abbreviated Ah. Chemical Capacity – full storage capacity of the chemistry when measured from full to empty or empty to full. This is normally defined at a given C-rate and maximum and minimum voltages.
What is the difference between battery capacity and voltage?
For example, a battery pack with four cells in series would have a nominal voltage of around 14.8V. Capacity, on the other hand, is measured in milliamp-hours (mAh) or amp-hours (Ah) and indicates how much energy the battery can store. A higher capacity means longer runtimes between charges.
What determines the energy capacity of a cell pack?
Variation in cell capacity and resistance along with number of cells in series and parallel will determine the actual energy capacity of any pack. Temperature management of the cells and variations across the pack will influence power and energy.
