Ano ang plate ng proteksyon at ang sistema ng pamamahala ng baterya? Ano ang ginagawa nito?

2020-10-14
The battery protection plate can play the role of charge and discharge protection for the series and parallel battery packs, and can detect the overvoltage, overcurrent, overtemperature, undervoltage and short circuit state of each single battery in the battery pack, so as to extend the service life of the battery and avoid damage of the battery due to overdischarge. The protection plate of lithium battery is an indispensable part of lithium battery.



The protection plate of lithium battery also has the function of balanced protection, there are two ways of energy dissipation and energy conversion. Energy-dissipating equalization refers to the use of electrical resistance to dissipate the excess energy in a single cell with high power or voltage in a series of cells. Energy dissipation equalization can be divided into charging equalization, voltage fixed-point equalization and static automatic equalization.





Charging equalization: When charging, the protection plate activates equalization protection when the voltage of any of the batteries is higher than all the average voltages.



Pagpapantay-pantay ng punto ng boltahe: ang plato ng proteksyon ng baterya ng lithium ay naayos sa isang punto ng boltahe upang simulan ang pagpapantay, na isinasagawa lamang sa pagtatapos ng pagsingil ng baterya, at ang oras ng pagpapantay ay maikli.



Static automatic equalization: during charging or discharging, even if the battery is in static shelving state, when the voltage is inconsistent, the lithium battery protection plate will start the equalization protection until the voltage is consistent.



Ang mode na transfer-enerhiya ay upang ilipat ang baterya na may malaking kapasidad sa baterya na may maliit na kapasidad sa paraan ng pag-iimbak ng enerhiya, upang balansehin ang kapasidad ng baterya, na nahahati sa kapasidad na pare-pareho ang balanse at kapasidad na nakapirming-point na balanse.



Sistema ng pamamahala ng baterya



Maaaring sukatin ng System ng Pamamahala ng Baterya (boltahe) ang boltahe ng Baterya, at may kasamang function din ng proteksyon ng Baterya, pagpapaandar ng balanse ng baterya, pag-andar ng baterya, pag-andar sa pagsukat ng enerhiya, pagpapaandar ng komunikasyon sa network at iba pa. Maaaring maiwasan ng system ng pamamahala ng baterya ang mga hindi normal na kondisyon tulad ng sobrang paglabas, sobrang pagsingil at higit sa temperatura.



The existence of the battery management system is to monitor, protect and manage the lithium battery equably, so as to improve the working efficiency of the lithium battery.



Similarities and Differences between lithium battery protection plate and battery management system BMS



Both the lithium battery protection plate and the battery management system protect the lithium battery. The difference between them is:



1. The protection plate of lithium battery is composed of IC, MOS tube, resistor and capacitor elements, which is an important component of lithium battery. The battery management system, which can be edited and comes with battery management software, is relatively more intelligent and ACTS as the brain of a lithium battery.



2. Lithium battery protection plate plays an important role in the field of 3C lithium battery and power battery, while the battery management system is applied in the field of power battery.



3. Ang system ng pamamahala ng baterya ay mas mahusay na nagpapatakbo kaysa sa plate ng proteksyon ng baterya, ngunit ang pagganap nito ay hindi matatag sa mababang temperatura
