Hpa Majaw N-gun hpe n-gun jaw ai kun?
Lithium battery law law gaw anhte a gat de n-gun ja ai cell ni hte bai sa wa ai hpe ngai mu yu sai. Shi hta na 9 lang, madu wa gaw dai hpe n-gun ja ai lead-}acid charger de gang bang nna, hkawm mat wa ai. Overcharge gaw hkum tsup ai LiFePO4 battery hpe sat na matu lawan dik ai ladat rai na re.
Overcharge gaw current gaw cell langai mi hpring sai hpang matut manoi lwi shang wa ai shaloi byin pru wa ai. Lithium iron phosphate cell ni gaw cell langai hta 3.65V grup yin hta grau law ai. 12V battery pack hpe 14.6V hta charge galaw ai hpe jahkring kau ra ai. Dai hpe lai nna nang gaw manghkang hpe hpyi nga ai.
Hpa majaw nga yang, kata de gara lam ni shut mat ai kun?
3.65V hpe lai nna LiFePO4 cell hpe shadut ai shaloi, lithium ions ni gaw gara de mung n sa na. Cathode gaw saturated re. Extra lithium gaw anode ntsa kaw na metallic lithium hku nna pru wa hpang wa ai. Ndai gaw n kaja ai shiga re. Metallic lithium gaw reactive rai nna, plating gaw n mai nhtang wa ai. Na a capacity hkrat mat nna n bai wa ai.
Ngai gaw lai wa sai shaning hta shi a charge controller hpe shut ai majaw shi a nta battery bank hpe 14.8V hta woi awn ai la langai hte tsun shaga ai. Shi a atsam 30% hpe sum mat chye ai. Dai cell ni gaw hkrit tsang hpa n rai tim shi gaw madung hku nna shi jaw ai gumhpraw htam masum hta na htam mi hpe kabai kau ai.
Chargers hte Charge hpe hkang ai ni
Ngai mu mada ai manghkang law malawng gaw, n htap htuk ai arung arai ni kaw na pru wa ai. Lead- ]acid charger ni gaw lithium a matu n bungli galaw ai. 13.6-13.8V hta AGM charger langai mi gaw 14.4-14.7V du hkra manu dan ai. Dai nambat ni gaw lithium specs hte ni htep ai hku mu lu ai raitim charge algorithm gaw tsep kawp shai ai.
Lead-}}}} ai ai battery ni gaw, n-gun kaba ai voltage hta aten galu hkam la lu na matu ra sharawng ai. Lithium battery ni gaw dai hte nhtan shai ai hpe ra sharawng ai. Nang gaw voltage target hpe gap dat ai shaloi nang jahkring kau ai. Lithium charger (sh) lithium profile hte hkrak ai MPPT hpe hkang ai kaja ai hpe san seng hkra daw kau na re. AGM charger langai mi gaw dai kaw hkying hkum law law current hpe shadut ai hku dung na re.
Victron, Renogy, EPver- hta na law malawng gaw ya aten hta lithium presets ni nga ai. Dai ni hpe lang u.
BMS gaw yawng hpe n gram lajang ai
Lithium battery shagu hta battery hparan ai ladat nga ai. Masha law law gaw BMS gaw battery hpe n-gun n jaw ai ngu myit la ma ai. N galaw ai.
BMS gaw shim lum ai backstop re. Voltage grai tsaw wa ai shaloi, pack hpe dawm kau ya ai. Ndai lam gaw thermal hprawng ai hte wan hpe makawp maga ya ai. Raitim, bai galaw ai BMS hkrun lam ni gaw cell ni hpe naw stress naw galaw nga ai. Dai ceiling hpe nang hkra ai shaloi shagu, cutoff kick n shang shi yang, hkra machyi ai lam nkau mi byin wa ai. Battery hpe hkam kaja hkra n galaw ya ai.
15.2V (sh) dai hta jan ai BMS cutoffs ni hte manu n hkrat ai import galaw da ai battery ni hpe mu yu sai. Dai gaw grai hpang hkrat sai. BMS galaw ai aten du wa ai shaloi, cell ni gaw grai law ai masa hta dung nga sai.
Temperature gaw Worse galaw ai
Overcharge hkra machyi ai gaw katsi ai hte grau lawan wa ai. Shi a voltage limit hpe lai nna, katsi ai battery hpe charge galaw ai gaw, nta kata na nbung katsi ai shara hta dai zawn sha galaw ai hta grau sawng ai. Engine rung (sh) n pru ai shara ni hta hka lim ai lam ni gaw grau yak ai aten nga ai. Na a battery bay gaw 100℃hpe ayan hkra yang, na a margin gaw shut ai lam yawm mat ai.
BMS unit nkau mi hta nbung katsi ai lam hpe hka wa ai. Manu n hkrat ai ni law malawng gaw n chye ai.
Mai byin ai lam kaw nna nga nga ai
Na a charge voltage hpe shawng nnan shani kaw nna hkrak hkra tawn da u. LiFePO4 battery law malawng a matu, 14.2-14.4V gaw, n-gun kaba ai charge galaw na matu kaja ai yaw shada lam langai rai nna, 13.6V gaw float a matu re. Na a galaw shapraw ai wa a specs hpe jep yu u, hpa majaw nga yang, brand nkau mi gaw loi mi shai ai. Battle Born gaw 14.4V hpaji jaw ai. Renogy gaw 14.2V ngu tsun ai. Lahkawng yan gaw kaja hkra galaw ai.
Dai charger hpe box kaw na hkum kam. Ngai gaw shut ai lam sha re ai factory settings ni lawm ai brand nnan ni hpe mu yu sai. Multimeter hte minit kru daram jai lang nna, terminal ni hta teng sha hpa byin nga ai hpe jep joi yu u.
Nang solar hpe galaw nga ai rai yang, na a absorb time setting hpe yu u. Lithium battery law malawng gaw 20{3}}30 minutes hta jan nna n ra ai. Setup nkau mi gaw zero absorption time hte kaja hkra galaw ai- voltage hpe hkra nna float de galai kau ai.
Overcharge gaw n yak ai. Voltage hpe gara kaw nga ai hpe tawn da nna battery gaw n-gun rawng na re. N myit mada ai sha, shi a malai lahkawng ning laman pack nnan mari na re.
