Hardware-type protection board: Use special lithium battery protection chip, when the battery voltage reaches the upper limit or lower limit, the control switch device MOS tube cut off the charging circuit or discharging circuit, to achieve the purpose of protecting the battery pack. Characteristics: 1.
When the lithium battery is used in PACK, it is more likely to over-charge and over-discharge, which is caused by the consistency difference of the cell. If the charging and discharging process is not properly controlled, it will be further increased, resulting in the phenomenon of over-charging and over-discharging of part of the cell.
Because of the material characteristics of the lithium battery itself, it can not be over-charge, over-discharge, over-current, short-circuit and ultra high or low temperature charge and discharge, so the application of lithium battery always needs a protection circuit.
Lithium manganate(LMO) series: Cut-off voltage ≤4.2V, discharge cut-off voltage ≥2.7V Term: Over-charge: The charging voltage exceeds the upper limit voltage. Over-discharge: The discharge cut-off voltage is lower than the lower limit voltage. What are the consequences of lithium-ion battery over-charge and over-discharge?
The over-current capacity of the protective board is determined by the over-current capacity and quantity of the MOS tube. The MOS tube accounts for most of the cost of the protective board. Generally speaking, the charging current is smaller and the discharge current is larger.
As with the single cell, in the multi-cell protection circuit, the protection board must also be able to provide over-charge, over-discharge, over-current, short circuit protection against the cell. Below is system schematic of software-type protection board:
