Battery EfficiencyBattery efficiency, also known as round-trip efficiency, is the charging and discharging efficiency of the battery or the loss degree of the battery in use. According to the laws of physics, the transfer of energy from one form to another results in energy loss. In this case, the b…

A: Open circuit voltageWhen the battery is not charged and discharged and there is no load, the potential difference between the two poles of the battery is called the open circuit voltage.The open circuit voltage of the battery will vary according to the materials of the positive and negative elect…

When the battery is discharging, the voltage drops to the lowest working voltage value that the battery is not suitable to continue discharging. According to different battery types and different discharge conditions, the requirements for the capacity and life of the battery are also different, so the specified discharge termination voltage of the battery is not the same.

When the LiFePO4 battery is charged, the lithium ion Li + in the positive electrode migrates to the negative electrode through the polymer separator; during the discharge process, the lithium ion Li + in the negative electrode migrates to the positive electrode through the separator. The lithium ion battery system is named because lithium ions migrate to each other during charge and discharge.

No matter what state the LiFePO4 battery is in, it can be charged at any time. There is no need to discharge the power before charging.
