1.Passive equalization

Ho leka-lekanya ka mokhoa o sa reroang ka kakaretso ho ntša betri ea lithium-ion e phahameng ka ho ntša motlakase, ho ntša matla ka mokhoa oa mocheso ho reka nako e eketsehileng ea ho tjhaja libeteri tse ling. Ka tsela ena matla a sistimi eohle a fokotsoa ke betri e nang le matla a fokolang. Nakong ea ho tjhaja, libeteri tsa lithium-ion ka kakaretso li na le boleng ba voltage ea tšireletso ea moeli oa tefiso, ha mohala oa libeteri o fihla boleng bona ba motlakase, boto ea ts’ireletso ea betri ea lithium-ion e tla khaola potoloho ea ho tjhaja ebe e emisa ho tjhaja. Haeba motlakase oa ho tjhaja o feta boleng bona, boo hangata bo tsejoang e le overcharge, betri ea lithium-ion e ka chesa kapa ea phatloha. Ka hona, liphanele tsa ts’ireletso ea betri ea lithium-ion hangata li na le ts’ireletso ea ho tjhaja ho feta tekano ho thibela betri hore e se ke ea lefisoa ho feta tekano.

Molemo oa ho leka-lekanya feela ke theko e tlaase le moralo o bonolo oa potoloho; ‘me bothata ke hore masala a fokolang a betri a sebelisoa e le tekanyo ea ho lekana, kahoo ho ke ke ha khoneha ho eketsa matla a betri ka masala a fokolang,’ me 100% ea matla a lekanang a senyeha ka mokhoa oa mocheso.

2. Ho lekana ka mafolofolo

Ho lekana ho sebetsang ke ho lekana ka phetisetso ea matla ka katleho e phahameng le tahlehelo e tlase. Mokhoa o fapana ho tloha ho moetsi ho ea ho moetsi ‘me hona joale ho lekana ho fapana ho tloha ho 1 ho ea ho 10? A. Litheknoloji tse ngata tse sebetsang tsa ho leka-lekanya tse fumanehang hona joale ‘marakeng ha li e-s’o hōle, e leng se lebisang ho tsoa ho feteletseng le ho senyeha ha betri ka potlako. Boholo ba ho lekanngoa ka mafolofolo ‘marakeng ho sebelisa molao-motheo oa ho feto-fetoha ha motlakase, ho itšetlehile ka lichelete tse theko e boima tsa baetsi ba li-chip. ‘Me ka tsela ena, ho phaella ho chip ea equalization, empa hape le li-transformer tse theko e boima le likarolo tse ling tsa peripheral, tse khōloanyane le tse theko e boima.

Melemo ea ho lekana ka mafolofolo e hlakile: ts’ebetso e phahameng, matla a fetisetsoa, ​​tahlehelo ke feela tahlehelo ea coil ea transformer, e ikarabellang bakeng sa karolo e nyenyane; ho lekana hona joale ho ka etsoa ho fihlela li-amps tse seng kae kapa esita le boemo ba 10A, phello ea ho lekana e potlakile. Ho sa tsotellehe melemo ena, ho lekana ka mafolofolo ho boetse ho tlisa mathata a macha. Ntlha ea pele, mohaho o rarahane, haholo-holo mokhoa oa transformer. Mokhoa oa ho rala matrix a switjha bakeng sa libeteri tse ngata kapa tse makholo, le mokhoa oa ho laola mokhanni, kaofela ke hlooho e bohloko. Hona joale theko ea BMS e nang le ts’ebetso e sebetsang ea ho lekana e tla ba e phahameng haholo ho feta ea passive equalization, e leng eona e fokotsang ho phahamisa ts’ebetso ea BMS e sebetsang ho feta kapa ka tlase.

Passive equalization e loketse lisebelisoa tse fokolang tsa lithium-ion battery pack, ha ho lekanngoa ka mafolofolo ho loketse lisebelisoa tse phahameng tsa matla a matla a lithium-ion betri pack. Bakeng sa BMS, ntle le ts’ebetso ea ho lekana ke ea bohlokoa haholo, leano la ho lekana ka morao le bohlokoa ho feta.

Melao-motheo ea ho lekana ha betri ea lithium-ion

Mekhoa e tloaelehileng ea ho tjhaja tekano e kenyelletsa ho tjhaja ha shunt resistor equalization charging, on-off shunt resistor equalization charger, average cell voltage equalization charger, switched capacitor equalization charger, buck converter equalization charger, inductor equalization charger, joalo-joalo Ha u tjhaja libeteri tsa lithium-ion ka letoto la lihlooho. ka lihlopha, betri e ‘ngoe le e’ ngoe e lokela ho netefatsoa hore e tjhajiloe ka ho lekana, ho seng joalo ts’ebetso le bophelo ba betri kaofela li tla ameha nakong ea ts’ebeliso.
