1. Memory Effect:

Rechargeable batteries often work under fully charged conditions, and their capacity will quickly or gradually fall below the rated capacity. In the past, some mobile phone batteries were required to be discharged before charging, because nickel-metal hydride and nickel-cadmium batteries have memory properties. Lithium iron phosphate batteries do not have this phenomenon. No matter what state the LFP battery is in, it can be charged at any time. There is no need to discharge the power ALL before charging.


2. Specific Energy:

Also called energy density, it refers to the energy obtained by a unit mass or unit volume of a battery, which is called mass specific energy or volume specific energy.


3. SOC (State of Charge):

Refers to the ratio of the remaining capacity of the battery after a period of use or long-term storage to its fully charged capacity. At present, the SOC of the battery corresponding to the Bluetooth device can be observed in real time on the APP, which generally refers to the current remaining power, expressed as a percentage.


4. SOH (State of Health):

The ratio of the battery's dischargeable capacity to the new battery's rated capacity under certain conditions, which characterizes the current battery's ability to store electrical energy relative to the new battery, and expresses the battery's state from the beginning of its life to the end of its life as a percentage, which is used to quantify Describe the current battery performance status, determine the degree of degradation or aging of the battery capacity, which represents the health status of a battery. Generally, the battery SOH lower than 80% can be regarded as the end of life.


5. Voltage Platform:

When discharging, the voltage change of the battery is not a slope drop. In general, the beginning of the discharge, the voltage drop relatively quickly, over a period of time, with the discharge of the battery voltage is almost no change, or changes very little, which accounted for most of the entire discharge period of time, is discharged Platform voltage. Generally speaking, the nominal voltage is the center voltage of the platform voltage. Near this voltage, the voltage changes slowly during charging and discharging. During constant current charging and discharging, the voltage has a steady process, and this steady value is the charging and discharging platform. For example, the platform voltage of a nominal 3.7V lithium battery is around 3.7V, and the nominal voltage of a 3.2V lithium iron phosphate battery is around 3.2V.
