Lapud nilasus milyon so mobile phone ed interon mundo, say pakagamor na kaligenan et mankaukolan na kulang ya sakey ed kada sanlasus milyon ya failure rate. Balet, say inkagba na saray circuit board et kaslakan ya mas atagey nen say sakey ed sanlasus milyon. Kanian, say desinyo na sistema na baterya et nepeg ya walaan na ag-onkulang ed duaran linya na depensa. Say kaslakan ya lingo ed desinyo et say direktan pangikarga ed battery pack panamegley na adapter. Saya so mangiyan ed amin a responsabilidad parad proteksion ed sobran karga ed proteksion a board ed battery pack. Anggaman abeba so bilang na ag-inkayadyari na protection board, anggano sakey ed kada milyon, wala nin siansia so insabog ya inagew-agew ya nagagawa ed interon mundo. No say sistema na baterya et mangiiter na duaran linya na depensa sumpad overcharge, over-discharge, tan overcurrent, ya kada depensa et walay failure rate ya sakey ed kada samploran libo, say duaran linya na depensa et makapangibawas na failure rate ed sakey ed sanlasus milyon.
Battery Pack Function: Current Limiter. No alaen so sakey ya alimbawa na sistema na baterya na mobile phone, say sistema na proteksion ed overcharge et manguusar na output voltage na charger ya aka-set ed manga 4.2V pian nadampot so unonan layer na proteksion. Diad onian paraan, anggano onkapuy so protection board ed battery pack, ag-onsobra so karga na baterya tan magmaliw ya delikado. Say kumadwan proteksion et say overcharge protection function ed protection board, ya kaslakan ya aka-set ed 4.3V. Kabaliksan na saya ya agla kaukolan ya putoten na protection board so charging current; onkiwas labat itan no say boltahe na charger et abnormal ya atagey. Say proteksion ed overcurrent et aasikasoen na protection board tan current limiter, ya mangiiter na duaran layer na proteksion sumpad overcurrent tan external short circuits. Lapud say over-discharge et nagagawa labat legan ya uusaren so elektronikon produkto, say circuit board na elektronikon produkto so kaslakan ya mangiiter na unonan layer na proteksion, bangta say protection board ed battery pack so mangiiter na komadua. No say elektronikon produkto et makanengneng na boltahe na suplay ya abeba nen 3.0V, nepeg ya automatikon onsara. No ag-inlaktip iyan function ed desinyo na produkto, isara na protection board so discharge circuit no onleksab so boltahe ed 2.4V.
