Lead-acid battery hi kum zabi 19-na laihawl vela an siam chhuah atang khan energy storage technology-ah lungphum a ni tawh a ni. Heng power source rintlak tak takte hi hmanraw hrang hrangah hman a ni nasa hle. Lead-acid battery hnathawh dan hriatthiam hi an hnathawh that leh an dam rei theih nan a pawimawh hle.
Lead-acid battery hi thil pawimawh engemaw zat a awm a, chungte chuan electrical energy tha taka khawlkhawm leh chhuah tir turin an thawk ho a ni. A bulpui berte chu:
Plate: Lead dioxide (positive plate) leh sponge lead (negative plate) atanga siam niin, hengte hi electrolyte solution-ah an thun a ni.
Electrolyte: Sulphuric acid leh tui inzawmkhawm a ni a, hei hian energy dahkhawmna atana chemical reaction mamawh a ti awlsam a ni.
Separators: Positive leh negative plate inkarah hian insulating material te tak te dah a ni a, hei hian short-circuiting a awm loh nan ionic movement a phalsak bawk.
Container: Casing nghet tak, a chhunga thil awm zawng zawng dahna, a tlangpuiin plastic emaw rubber emaw a chhe thei lo atanga siam a ni.
Terminals: Battery hian terminal pahnih a nei a, positive leh negative te an ni. Sealed terminal hian current discharge sang tak leh service life rei tak a siam thei a ni.
Lead-acid battery hnathawh dan hi plate-a active material leh electrolyte solution inkara reversible chemical reaction awm danah a innghat a ni.
Discharge lai hian a hnuaia thil thleng hi a thleng thin:
Electrolyte chhunga sulphuric acid hian positive (lead dioxide) leh negative (sponge lead) plate pahnih nen an inrem a. He reaction hian plate pahnih ah lead sulfate a siam a, chutih rualin pawn lam circuit hmangin electron a chhuah tir a, electrical current a siam chhuak bawk. Negative plate atanga positive plate-a electron te chu pawn lam load hmanga an kal zel chuan connected device-ah energy a pe chhuak thin.
Charging lai hian he process hi a reverse a ni:
Pawn lam power source chuan battery terminal hrang hrangah voltage a pe a. Voltage hman chuan electron te chu negative plate-ah a hruai kir leh a, chutih rualin lead sulfate chu a awm dan pangngaiah a chantir leh a ni—positiv plate-ah lead dioxide leh negative plate-ah sponge lead. Electrolysis laiin tui molecule a inthen darh chuan sulphuric acid concentration a sang chho zel a ni.
Hetiang cyclical nature hian lead-acid battery te chu uluk taka enkawl a nih chuan a chhe lutuk lovin vawi tam tak recharge theih a ni.
Charging Technique dik tak hman dan tur
Lead-acid battery-a performance tha ber neih theih nan charging practice tha tak neih a pawimawh hle:
Constant Voltage Charging: Hetiang method hmang hian voltage chu constant value-a dahna hmunah charge theih a ni. A thatna chu battery charge state a inthlak ang zelin charging current chu automatic in a adjust thin a ni.
Three-stage Charging: Bulk charge (constant current), absorption charge (constant voltage), leh float charge (maintenance mode) te a huam a, he technique hian battery component-a stress nasa lutuk awm lovin uluk taka recharging a siam thei a ni.
Charging laiin temperature enfiah hi a pawimawh hle a; temperature sang chuan gassing emaw thermal runaway ang chi thil tha lo tak tak a ti chak thei a ni.
Discharge dan tha tak tak te
Battery hriselna tichhe thei discharge thuk tak a awm loh nan discharge cycle te hi uluk taka enkawl tur a ni:
A theih phawt chuan 50% depth-of-discharge aia tam discharge loh tur; deep discharge tam lutuk hian dam chhung zawng zawng a ti tawi hle.
Lead-acid battery hi hmanraw hrang hranga energy dahkhawmna rintlak tak atan a pawimawh hle. An structure leh working principle hriatthiamna hmang hian users te chuan performance an optimize thei a, an dam chhung pawh an ti rei thei bawk. Charging leh discharge monitoring dik tak neih a pawimawh hle. Implementing a ni DFUN Battery Monitoring Systems (BMS) chuan lead-acid battery chu energy storage solution-a thil pawimawh tak a nih reng theih nan a enkawl a ni. He system hian cell pakhat zel voltage, leh multi-cell configuration-a charge/discharge current te a enfiah a, control leh maintenance tihchangtlun nan battery activation leh battery balancing features te a keng tel bawk.
