State of charge (SoC) is the level of charge of an electric battery relative to its capacity. The units of SoC are percentage points (0% = empty; 100% = full). An alternative form of the same measure is the depth of discharge(DoD), the inverse of SoC (100% = empty; 0% = full). SoC is normally used when discussing the current state of a battery in use, while DoD is most often seen when discussing the lifetime of the battery after repeated use.
This post shows how to control the charging and discharging of an Li-ion (Lithium-ion) battery using SOC (State of Charge) parameters as a decisive factor in limiting the charging and discharging cycles. Do refer the video in case of any queries, and if you still have any doubts, do post them in the comments section and we shall get back to you at the earliest.
Hello sir in this video why after discharging of the battery the graph become constant? and not charging again?
