Charging Voltage: When you recharge a battery, the charging voltage is the amount of voltage applied to push current back into the battery. This voltage is typically higher than the nominal voltage to ensure the battery reaches a full charge.
State of Charge (SOC): A fully charged battery will have a higher voltage than a battery that’s running low. When you charge a battery, the voltage gradually increases until it reaches a safe maximum level. Temperature: Temperature can also play a role in battery voltage.
Nominal Voltage: This is the battery’s “advertised” voltage. For a single lithium-ion cell, it’s typically 3.6V or 3.7V. Open Circuit Voltage: This is the voltage when the battery isn’t connected to anything. It’s usually around 3.6V to 3.7V for a fully charged cell. Working Voltage: This is the actual voltage when the battery is in use.
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:
For a fully charged battery, aim for 3.65 volts. Here’s a quick reference for charging levels: When charging, use a bulk charge process first to reach the target voltage quickly. After that, a float charge is used to maintain the battery without overcharging, usually around 3.4 V per cell.
Load Voltage: This is the voltage a battery delivers when it is powering a device or under load. It tends to be lower than the OCV because the battery’s internal resistance causes some energy loss. Charging Voltage: When you recharge a battery, the charging voltage is the amount of voltage applied to push current back into the battery.
Lithium Battery Voltage Chart
For example, a fully charged lithium-ion cell typically has a voltage of 4.2V, while a discharged cell may have a voltage of 3.0V or lower. Monitoring voltage is crucial for maintaining lithium batteries, as overcharging or over-discharging can damage the cells and reduce their lifespan.
