The balanced working principle of the lithium battery protection board
The lithium-ion battery protection board is the charge and discharge protection of the series lithium-ion battery pack; When fully charged, the voltage difference between each single battery can be guaranteed to be less than the set value, and the uniform charging of each single battery of the lithium-ion battery pack is realized, which effectively improves the charging effect under the series charging mode. At the same time, the over-voltage, under-voltage, over-current, short circuit and over-temperature states of each single battery in the battery pack are detected to protect and prolong the service life of the battery; Under-voltage protection prevents each single cell from being damaged due to over-discharge when it is discharged.
The commonly used equalization charging technologies include constant shunt resistance equalization charging, on-off shunt resistance equalization charging, average battery voltage equalization charging, switching capacitor equalization charging, step-down converter equalization charging, inductor equalization charging, etc.
When the group of lithium-ion batteries is charged in series, it is necessary to ensure that each battery is charged equally, otherwise the performance and life of the whole group of lithium-ion iron phosphate batteries will be affected during use. The existing single-cell lithium-ion battery protection chip does not have the equalization charge control function, and the equalization charge control function of the multi-cell lithium-ion battery protection chip needs to be connected to an external CPU; Through serial communication with the protection chip, the complexity and design difficulty of the protection circuit are increased, the efficiency and reliability of the system are reduced, and the power consumption is added.
According to the application requirements, the equalization principle of lithium-ion battery protection board can protect and evenly charge the power lithium-ion battery pack of any structure and voltage level after changing the type of protection chip and the number of series, the power level of switching devices and energy consumption components in the circuit.
During the charging process of lithium-ion batteries, each lithium-ion battery is equipped with a equalization circuit, and the voltage of each battery is controlled by the equalization circuit of the lithium-ion battery protection board during charging, so that each string of batteries is kept in the same state to ensure the performance and life of the lithium-ion battery
