1. Basic Concepts 1. DOD (Depth of Discharge) DOD refers to the percentage of the battery’s capacity that has been discharged during use, typically expressed in Aยทh or as a percentage (%). The calculation formula is: DOD = (Discharged Amount / Rated Capacity) ร 100% This parameter describes the extent to which the battery has … Read more
1. What is SOC? SOC (State of Charge) refers to the “remaining battery charge,” similar to the fuel gauge in gasoline vehicles, reflecting how much charge is left in the battery (usually expressed as a percentage, e.g., 80% SOC means 80% of the charge is still available). For new energy vehicles, the accuracy of SOC … Read more
High-precision magnetic modulation current sensors are primarily used in the lithium battery industry for the precise measurement of current during the charging and discharging processes of batteries. These sensors utilize the principle of electromagnetic induction to determine the current flowing through the sensor by measuring the changes in magnetic flux within the battery circuit. During … Read more
