The battery charging voltage ranges between 3.6 to 4.2 volts. Like lead-acid batteries, lithium-ion batteries have different stages of charging. Lithium-ion batteries require a constant voltage to charge safely. The constant current and the constant voltage are required in this type of battery.
Charging batteries is simple (in theory) – put a voltage across the terminals and the battery charges. If safe charging, fast charging and/or maximum battery life are important, that’s when things get complicated.
The battery charging voltage for a lead-acid battery varies with the type, charging method and purpose of the battery. Usually, the charging voltage ranges from 2.25 to 2.45 volts. Upon charging, a lead-acid battery passes through three stages; bulk, absorption and float. This also leads to a variation of voltage in these stages.
The specifications of battery chargers may vary with different battery types. They often specify the voltage and current output that can affect the charging process. A charger with low output voltage may not be able to charge a battery to its full capacity. On the other hand, a higher voltage output could damage the battery or shorten its lifespan.
There are several types of voltage charging methods, including the following: The constant voltage method keeps a constant voltage during the charging process. However, there is a gradual decrease in current as the battery charges. The charging process stops after this current reaches a certain level.
Key Parameters in Lithium-ion Battery Charging Several crucial parameters are involved in lithium-ion battery charging: Charging Voltage: This is the voltage applied to the battery during the charging process. For lithium-ion batteries, the charging voltage typically peaks at around 4.2V.
