Battery hpe hkang ai ladat

Battery hpe atsawm sha hkang lu na matu jai lang ai Battery Management System (BMS) ngu ai ladat hpe tsun ai re. Wan jak mawdaw ni a matu, kaja wa-hpan da ai BMS hardware hte software gaw, mawdaw gau ai shara hpe kaja wa jat ya lu ai, battery pack a prat hpe galu shangun lu ai, bungli galaw ai manu hpe shayawm ya lu ai, power battery pack a shimlum lam hte kam hpa mai ai lam hpe hkam la lu ai. Power battery hpe hparan ai ladat gaw wan jak mawdaw ni a matu n mai malap ai madung daw langai byin wa sai. Ndai daw hta, power battery hparan ai ladat a npawt nhpang, bungli galaw ai lam ni, bungli galaw ai ladat ni hpe tsun dan na re.

System gawgap ai lam

Battery hpe hparan ai ladat (BMS) a hardware hta madung hku nna Battery hpe hparan ai ladat (BMU), Cell hpe hparan ai ladat (CMU), sensor ni, wiring harnesses ni lawm ai. ladat, hte system manu, kam hpa mai ai lam, n-gun rawng ai hte gram lajang na matu loi ai, shadawn shadang hkrak ai lam ni hpe hkra machyi shangun ai. BMS kata na controller ni a lapran na topology hpe madung tawn nna, BMS ni hpe galu kaba ai hku garan ginhka mai ai: hpawng de da ai hte garan gachyan ai.

1. Hpungdim BM .

Integrated BMS ngu ai hpe single-unit BMS ngu nna mung shamying ma ai, dai gaw core controller (BMU) hte cell controller (CMU) hpe langai sha tai hkra hpawng de da ai BMS hpe tsun mayu ai rai nna, core controller gaw data hpe hkap la ai, galaw ai, hkang ai bungli ni hpe hkrak galaw ya ai. Integrated BMS a topology hpe sumla 8-1 hta madun da ai.

 

Integrated BMS ni gaw n-gun n law ai, n-gun ja ai anti-hkap la ai atsam nga ai, on-board hta lawan ai matut mahkai lam hpe jaw ya ai majaw, synchronous data ni hpe lu la na matu loi ai. Dai hta n-ga, BMS magam bungli yawng hpe package langai hta sha galaw lu ai majaw, manu jahpu hpe shayawm ya lu ai. Raitim, hpawng de da ai BMS ni hta gaw, grai sawng ai matut mahkai lam ni hte wiring harness ni nga ai majaw, system a shara shagu hta short circuit byin wa ai shaloi, battery system hpe makawp maga na matu yak hkak nga ai. Battery module kaji ni a matu sha htuk manu ai rai nna, scalability hte gram lajang ai lam n kaja ai.

 

2. Garan gachyan ai BMS .

 

Integrated topologies ni hte n bung ai sha, garan gachyan ai htingnu gawgap ai lam ni gaw BMS a magam bungli hpe mainboard BMU hte slave CMU law law hku garan nna galaw ai. Modular hkrang gaw module hpe shinggyin la na matu asan sha galaw ya ai, sampling harness layout hpe grau kaja hkra galaw ya ai, voltage hkrat sum ai lam ni hpe shadawn sharam sha tawn da ai hte shayawm ya ai. N kaja ai lam ni hta manu grau tsaw ai hte grau sawng ai matut mahkai lam hte hkang zing ai hkrang masa ni lawm ai. Distributed BMS matut mahkai ladat amyu myu hpe madung tawn nna, shanhte hpe matut nna masum hku garan mai ai: shagan matut mahkai (Sumla 8-2 hpe yu u), Bus matut mahkai, daisy-chain matut mahkai.

 

(1) Shagan matut mahkai lamShagan matut mahkai ai lam hta, mainboard BMU gaw ginjaw kaw nga ai rai nna, CMU module langai hpra gaw BMS mainboard hte harness hku nna hkrak matut mahkai nga ai. Shagan matut mahkai lam ni gaw point-to-point hpe hkang lu na matu loi shangun ai, CMU node langai hkrat sum mat ai gaw system hpe grai n hkra ai. Raitim, module ni law wa ai hte maren, shagan matut mahkai lam hta matut mahkai lam ni a yak hkak ai lam gaw grai law wa ai majaw, gram lajang na matu yak hkak wa nna, scalability hpe mung shadawn sharam sha galaw lu ai. BMS mainboard port ni a shadawn sharam ai majaw, CMU module ni hpe ra sharawng ai hku n mai bang ai majaw, -madang kaba ai application ni hta grai n law ai.

 

(2) Bus hte matut mahkai ai lamBus- hpe madung tawn ai system gawgap ai lam gaw, sumla 8-3 hta madun da ai hte maren, modular hkrang shapraw ai lam hpe loi shangun ai. BMS hpe laksan hku nna, BMU, CMU, hte Battery Join Box (BJB) ngu ai hkang zing ai daw law law hku nna garan nna galaw ai. BMU, CMU, BJB ni hpe CAN (sh) kaga Bus network ni hku nna matut mahkai nga ai. BMU gaw battery hpe hparan na matu core algorithm bungli ni hpe galaw ya ai; CMU gaw cell voltage hpe lu la ai, rap ra hkra galaw ai, nbung katsi ai hpe shadawn ai lam ni hpe galaw ai; BJB gaw, n-gun kaba ai, n-gun, n-gun n-gun hpe lu la ai, contactor hpe mawdaw gau ai hte ana jep ai lam ni hpe galaw ya ai, battery pack a matu insulation hpe sawk sagawn ai lam ni hpe galaw ya ai; isolation gaw wan n-gun hpe garan ginhka ya ai, circuit board hpe wan nat kau na matu backflow hpe pat shingdang ya ai hte n-gun n-gun hpe pat shingdang ya ai.

 

Bus- hpe madung tawn ai htingnu gawgap ai lam gaw grau htuk manu ai matut mahkai lam ni hpe jaw ya nna, n-gun ja ai scalability hpe jaw ya ai, hardware htingnu gawgap ai lam hpe grai asan sha galaw ya ai, modularity hpe lu la ai, system hpe jai lang mai ai hte htaw sa mai ai lam ni hpe grau kaja hkra galaw ya ai. Shi a madung hkra machyi ai lam gaw, manu grai law ai majaw re.

 

Daisy-chaining ngu ai gaw, lai wa sai shaning ni hta byin pru wa ai, grai nnan ai matut mahkai ladat langai rai nga ai. Ndai interface gaw 1Mb/s du hkra hkum tsup ai-duplex SPI signal ni hpe n bung ai signal ni de galai shai ya lu nna, twisted-pair cable hte asan sha re ai, manu n law ai transformer hku nna shalai ya lu ai. Ga shadawn, Linear Technology a AFE jak ni (LTC6811) hpe shada da matut mahkai nna BMS langai hpe galaw mai ai. Kaji ai, manu n law ai-transformer langai mi gaw data isolator a shara hpe la ai. Madung hkang ai microprocessor maga de, adapter kaji IC (LTC6820) gaw madung hkang ai interface hpe jaw ya ai. Unidirectional daisy-chain networking gaw asan sha rai tim, gara node mung hkrat sum mat yang, system ting a matut mahkai lam hpe hkra machyi shangun chye ai. Dai majaw, sumla 8-4 hta madun da ai zawn, grau kaja ai ring daisy-chain hpe Tesla zawn re ai n-gun nnan mawdaw kaba galaw shapraw ai company kaba ni a BMS arung arai ni hta gyin shalat nna jai lang wa sai. CAN bus matut mahkai lam ni hte shingdaw yu yang, daisy-chaining gaw manu n law ai hte n-gun kaji ai raitim, scalability n kaja ai, node law dik htum n law ai, n-gun kaba ai n-gun hpe shinggyin tawn ai system ni zawn re ai grau sawng ai masa ni hta battery hparan ai lam hpe hparan na matu yak hkak ai.
