What is the relationship between voltage and charge in a lithium-ion battery?
The relationship between voltage and charge is at the heart of lithium-ion battery operation. As the battery discharges, its voltage gradually decreases. This voltage can tell us a lot about the battery's state of charge (SoC) – how much energy is left in the battery. Here's a simplified SoC chart for a typical lithium-ion battery:
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.
