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.
Common lithium-ion cells typically have a nominal voltage of about 3.6 to 3.7 volts. This range is standard for most consumer applications, including smartphones and laptops. The actual voltage can vary slightly based on the specific chemistry and design of the cell. Most lithium-ion batteries consist of multiple cells connected in series.
Minimum Voltage: Often around 2.5 volts, below which the battery may be considered fully discharged. Discharging a lithium-ion battery below this voltage can lead to irreversible damage. Nominal Voltage: As stated, the nominal voltage for most lithium-ion batteries sits at about 3.7 volts.
Voltage significantly impacts the performance of devices that use lithium-ion batteries. Voltage refers to the electrical potential that drives the flow of current in a circuit. In lithium-ion batteries, the nominal voltage typically ranges from 3.2 to 3.7 volts per cell. When voltage levels are optimal, devices operate efficiently and safely.
Electric Vehicles (EVs): EVs use large battery packs. Let's say each cell has a nominal voltage of 3.7 volts (common for lithium-ion cells). If an EV requires a 400-volt battery pack, you would need about 112 cells in series (400 volts / 3.7 volts per cell). This series configuration increases the voltage to meet the vehicle's requirements.
To simplify, you can think of nominal voltage as a battery’s midpoint voltage – not the highest or the lowest, but somewhere in between. This makes it a helpful point of reference when assessing battery performance during usage. Lithium-ion batteries typically have a voltage range that is crucial for their performance:
