What is the cause of excessive self-discharge of lithium-ion batteries?
There are two reasons for the excessive self-discharge of lithium-ion batteries: physical micro short-circuit and chemical reaction.
How to design the 18650 lithium ion battery protection circuit board?
The protection function of lithium-ion battery is usually completed by the protection circuit board and current devices such as PTC. The protection board is composed of electronic circuits, which can accurately monitor the voltage of the battery cell and the charging and discharging circuit under the environment of -40℃ to +85℃. It can control the on-off of the current loop in time; PTC prevents the battery from being damaged badly in a high temperature environment.
