1. Lithium battery ni a "fragility" hpe makawp maga ra ai
Lithium battery ni gaw lawu na masa ni hpe grai hkam sha chye ai:
Overcharge: Lawu tsang hta jan ai Voltage gaw electrolyte hpe jahten kau ai, gas shapraw ai, bawm kapaw ai lam ni pyi byin shangun na re.
Overdischarge: Lawu na shadawn sharam npu na Voltage gaw n kaja ai electrode structure hpe jahten kau na rai nna, battery n-gun hpe n mai gram lajang lu ai attenuation byin wa na re.
Overcurrent/short circuit: N-gun law ai gaw kata na short circuit hpe byin shangun nna, katsi ai hte wan hkru wa na re.
N kaja ai nbung katsi ai lam: N-gun n-gun kaba ai gaw, maga mi de na n-gun ni hpe lawan shangun nna, n-gun n law ai gaw lithium n-gun yawm mat ai (dendritic rawt jat lam) hpe byin shangun chye ai.
BMS a madung lit:
Tengman ai- aten hpe voltage, ya aten, nbung laru ni hpe yu reng ai.
Hkrit tsang hpa masa ni hta charge galaw nna, control circuits (MOSFET switch zawn re ai) ni hpe garan kau u.
Lahkawng{0}} shingkyit/masum(3) hpe makawp maga ai hpung
2. BMS n lu ai a akyu ni: tsin-yam tsindam ni
Battery hkra machyi ai lam: Average langai sha n-gun dat/overdischarge langai a majaw battery hpe n-gun n rawng hkra galaw kau ya lu ai.
Thermal hprawng ai lam: Shor circuit (sh) nbung laru kaba ai gaw, chain reaction byin shangun nna, wan hkru ai (sh) bawm kapaw ai lam byin shangun chye ai (Samsung Note7 mabyin zawn re ai).
Tara upadi hta hkrit tsang hpa ni: Mungdan law malawng gaw shimlam masat masa (UL, CE zawn re ai) hpe shapraw na matu lithium battery arung arai ni ra ai, BMS gaw masat masa galaw ai lam a madung daw langai rai nga ai.
3. "Ra ai" ngu ai BMS a matu mabyin masa ni
Consumer electronics: Mobile phone ni hte laika buk ni hpe htu ra ai{ga law malawng gaw battery pack hta hpawng de da ai) a n-gun hpe n-gun jaw ra ai{0}}in galaw ra ai.
Power battery ni: Wan jak mawdaw ni hte n-gun hpe shinggyin tawn ai ladat ni hta grau sawng ai BMS (balancing functions ni lawm ai) ra ai.
DIY battery packs: Single{0}}}cell 18650 ning na battery ni hpe makawp maga ai board ni hku nna series/parallel hku matut mahkai ra ai.
4. N bung ai lam ni hte sadi maja ai lam ni
Special industrial application ni: BMS hpe grai n law ai masa ni hta n lawm mai ai (aerospace-grade battery ni zawn re ai), raitim kaga redundant design ni hku nna shim lum lam hpe shim lum hkra galaw ra ai.
N kaja ai arung arai ni a hkrit tsang hpa: npu na n-gun n law ai- n-gun n law ai lithium battery ni gaw BMS n lawm ai (sh) npu na daw ni hpe lang mai ai, dai gaw shimlam hpe grai sawng ai hkrit tsang hpa ni hpe shabyin ya ai.
5. BMS hpe gara hku lata na?
Battery parameters: Battery amyu hte maren lata la na (ga shadawn, ternary lithium/lithium iron phosphate zawn re ai), voltage, hte n-gun atsam ni hpe lata la na.
Hkamja lam hte seng ai ra kadawn ai lam ni: madung makawp maga (overcharge/over discharge/short circuit) shing nrai, rawt jat galu kaba wa ai magam bungli ni (balancing, matut mahkai lam, nbung katsi ai lam hpe hkang ai).
Certification madang: UL hte IEC zawn re ai shimlam masat masa ni lawm ai arung arai ni hpe grau ra sharawng ai.
