How do I choose a lithium-ion battery pack?
When selecting a lithium-ion battery pack, understanding its voltage characteristics is crucial for ensuring optimal performance and longevity. Three key voltage terms define a battery's operation: Nominal Voltage, Charged Voltage, and Cut-Off Voltage.
What voltage should a lithium ion battery be at?
Most lithium batteries risk permanent damage below 2.5V per cell. For a standard 3.7V lithium-ion cell, voltages under 3.0V indicate deep discharge. Prolonged operation below this threshold degrades capacity, increases internal resistance, and may cause catastrophic failure.
What should you know about lithium ion batteries?
The most important key parameter you should know in lithium-ion batteries is the nominal voltage. The standard operating voltage of the lithium-ion battery system is called the nominal voltage. For lithium-ion batteries, the nominal voltage is approximately 3.7-volt per cell which is the average voltage during the discharge cycle.
What is the SOC voltage chart for lithium batteries?
The SoC voltage chart for lithium batteries shows the voltage values with respect to SoC percentage. A Li-ion cell when fully charged at 100%SoC can have nearly 4.2V. As it starts to discharge itself, the voltage decreases, and the voltage remains to be 3.7V when the battery is at half charge, ie, 50%SoC.
Which lithium ion battery is best?
For devices requiring compact designs and high energy densities, lithium-ion batteries with a higher nominal voltage of lithium-ion are used. For applications requiring low energy densities and higher safety along with long cycles, LiFePO4 cells with a slightly lower nominal voltage are thus used frequently.
What is the nominal voltage of a battery pack?
This value is commonly used to specify battery packs and serves as a general reference for comparing different battery chemistries. For a 3S Li-ion battery pack (three cells in series), the nominal voltage would be 10.8V (3.6V × 3). 2. Charged Voltage: The Maximum Voltage When Fully Charged What Is Charged Voltage?
