Lithium iron phosphate battery voltage

1. Lithium iron phosphate battery voltage refers to the potential difference within the lithium iron phosphate battery, one of the key factors to consider when using lithium iron phosphate batteries is the voltage, the voltage of lithium iron phosphate batteries is different from the voltage of the traditional lead-acid batteries, lithium iron phosphate batteries have different discharge curves, mainly because of the stable chemistry of lithium iron phosphate batteries, lithium iron phosphate batteries provide a nominal battery voltage of 3.2V, the traditional The nominal voltage of traditional lead-acid battery is 3.6V to 3.7V.

2.JMHPOWER brand Li-FePO4 batteries have a service life of more than 10 years, and can be widely used in various fields, such as solar energy storage, off-grid power systems, home backup power, etc. The batteries have high temperature resistance, which allows them to operate safely and efficiently. Moreover, JMHPOWER brand also operates solar energy system, which can charge LiFePO4 batteries and provide electricity for household use.

Charging Parameters of Lithium Iron Phosphate Battery

Charging parameters of LiFePO4 batteries are crucial to achieve the best performance of the battery, LiFePO4 batteries can be charged well under specific charging conditions, and understanding the charging parameters of LiFePO4 batteries can help prolong the service life of the batteries. The following table shows the charging parameters of 3.2V, 12V, 24V, 48V lithium iron phosphate batteries.

Lithium iron phosphate battery charging voltage type

Lithium iron phosphate battery has different voltage stages, including full charge voltage, floating voltage, equalization voltage, different charging stage voltage will be different, to understand the charging voltage stage of lithium iron phosphate battery can improve the performance and service life of the battery, as described below:

1. Full charging voltage

That is, the charging voltage, usually in the initial stage of charging lithium iron phosphate batteries, this voltage level is used for rapid charging until the battery power reaches 80% to 90% of the capacity.

2. Float charging voltage

Float voltage refers to the voltage maintained by the battery when it is fully charged and not loaded, keeping the battery in a fully charged state without overcharging. Different batteries have different floating voltages, mainly due to the different designs of battery manufacturers and battery management systems, the floating voltage of lithium-ion batteries is higher than that of lithium iron phosphate batteries. The floating voltage of LiFePO4 battery is usually between 3.3V and 3.4V per cell, and the floating voltage of Li-ion battery is 4,2V per cell, so LiFePO4 battery has a lower floating voltage, which helps to prolong the service life of the battery and improve the safety of the battery.

3. Equalization charging voltage

Equalization is used to balance the charge between each cell in the battery pack, to ensure that each cell gets the same charge, the equalization voltage is usually higher than the charging voltage, about 3.8V to 4V, this higher voltage ensures that the battery pack cells are fully charged, to prevent imbalance.
