Electrical Tara Ngu Ai Hpa Rai Kun?
Wan n-gun npawt tara
Wan jak mawdaw langai a madung daw gaw battery system rai nna, battery system a madung lam langai gaw shi a wan n-gun npawt tara rai nga ai. Wan n-gun npawt tara a architecture design gaw, mawdaw hkrang shapraw ai lam hta, battery system a matu ra kadawn ai lam ni hpe hkan sa na matu madung tawn nna, hkrang shapraw ai lam hpe jahtum tawn ngut ai hpang, battery system a bungli ni hpe dawdan ya ai. Ndai daw hta battery system a wan n-gun hte seng ai machye machyang nkau mi hpe tsun dan na re.
Wan jak hkrang shapraw ai lam
Battery system a wan n-gun hpe gram lajang na matu ra kadawn ai lam gaw battery system a ra kadawn ai lam kaw na pru wa ai re. Battery system a matu mawdaw ra kadawn ai lam hpe asan sha tsun ga nga yang: wan jak mawdaw a matu wan n-gun hpe shim lum ai hte hkang lu ai hku jaw ya na matu. Ndai ga si hta lawm ai madung ga si masum gaw .wan n-gun, hkang lu ai, Hteshim ai. Wan n-gun ngu ai gaw, wan n-gun jaw lu ai battery system kata na, battery module zawn re ai arung arai ni hpe tsun mayu ai. Controllable ngu ai gaw, battery system kata na Battery Control Unit (BCU), contactor (sh) relay, hte n-gun/n-gun hpe hkang lu ai sensor ni zawn re ai arung arai ni hpe tsun mayu ai. Safe ngu ai gaw, battery system kata na system shimlam hte seng ai arung arai ni hpe tsun mayu ai, dai ni gaw fuse hte Manual Service Disconnect (MSD) zawn re ai ni hpe tsun mayu ai. Hkrang 9-1 hta, lawu de tsun lai wa sai daw masum lawm ai, battery system langai a asan sha wan n-gun hte galaw da ai hpe madun da ai. Dai ni hta, battery module ni, Battery Control Unit (BCU), madung kaja ai matut mahkai lam, madung n kaja ai matut mahkai lam, lawan ai hku charge ai kaja ai matut mahkai lam, lawan ai hku charge ai n kaja ai matut mahkai lam, pre-charge relay, pre-charge resistor, current sensor, fuse hte Manual Service Disconnect (MSD) zawn re ai arung arai ni lawm ai.
Hkrang 9-1 hta mu lu ai hte maren, battery system hta Master Control Board 1, Slave Control Board law law, MSD 1, cell law law, n-gun kaba ai Relay, n-gun kaji ai wire shingnip ni, hte matut mahkai ai lam amyu myu lawm ai. Master Control Board gaw, n-gun kaba ai-relay logic hpe hkang ai, n-gun yawng hpe lu la ai, n-gun kaba ai connector hte MSD matut mahkai ai lam hpe yu reng ai, ya aten lu la ai, charge galaw ai hpe hkang ai, mawdaw hte matut mahkai ai lam, slave board shiga ni hpe shinggyin la ai, mara hpe sawk sagawn ai, program upgrad galaw ai zawn re ai magam bungli ni hpe lit la nga ai. Slave Control Board langai hpra hpe cell voltage (0~5V) lu la na matu gram lajang da nna, box kata na battery module langai hpra hta garan tawn da ai nbung n-gun hpe chye na lu ai sensor ni hpe mung bang da ai.
Hkrang 9-1 hta na battery system gaw grai loi ai rai nna, hka katsi ai system, katsi ai system, nbung katsi ai hpe hkang ai zawn re ai subsystem ni hpe n lawm shi ai.
Wan hte seng ai npawt tara ni
Hkrang 9-2 hta battery system langai a wan n-gun npawt tara hpe madun da ai. Ndai sumla kaw na mu lu ai hte maren, battery pack hta kaja ai hte n kaja ai contactor ni, n-gun n-gun n-gun n-rawng ai ni, n-gun n-rawng ai relay ni, MSD, battery hpe hparan ai ladat, ya aten na sensor ni hpe hpawng de da ai. Lawan ai/katsi ai charger hte lithium battery pack kata na contactor ni hpe Battery hparan ai ladat (BMS) hku nna hkang ai, kaja ai myit masa hpe hkan sa na matu hpaji jaw ai. Positive hte negative contactor ni hta karum shingtau ai lam ni hpe bang da nna, bai htang ai lam hpe battery hparan ai ladat de bai sa dat ai.
Pre-charge circuit gaw mawdaw a n-gun kaba ai -n-gun hpe charge galaw ya nna, pre-charge n-gun gaw n-gun n-gun rai nga ai. Battery hparan ai ladat a madung board a n-gun jaw ai lam gaw .ON power, live wire hte charge galaw ai hpe n-gun jaw ai. Dai hpe ON power hte n-gun dat ai shaloi, charge galaw ai shaloi shinggan na charge power source hte n-gun dat ai. Battery hpe hparan ai ladat hta insulation hpe ninghkap ai lam hpe chye lu ai hte busbar voltage hte current hpe chye lu ai bungli ni nga ra ai. Ya aten hpe sawk sagawn ai hta shunt (sh) Hall ya aten sensor ni hpe lang mai ai. Battery hpe hparan ai ladat hta insulation hpe ninghkap lu na matu hte mara ni hpe hparan lu na matu htap htuk ai ladat ni nga ra ai. Insulation hpe ninghkap ai lam hpe sawk sagawn ra ai lam ni hpe battery design input sheet hta hkan nna ra kadawn ai lam ni hta hkrak tup tsun da ai. Battery hparan ai ladat a main board gaw mungdan ting na charge galaw ai madang hte maren charge galaw ai hpe hkang ai hte CC/CP/CC2 hpe madi shadaw ai signal ni hpe mu lu na matu rai ra ai. AC charge galaw ai ladat ni hpe mungdan madang hta lawm ai Charging Mode 3 Connection Method B ngu ai laksan control pilot circuit npawt tara hte maren galaw ra ai, nta kata na 16A socket hte AC charge galaw ai pile hku nna AC hpe charge galaw lu na matu ahkang jaw ra ai. Power battery pack a lapran kaw gram lajang ai switch hte n-gun kaba ai-fuse hpe tawn da ra ai. Battery pack gaw split-box system rai yang, box langai hte langai a wan n-gun lapran shara hta gram lajang ai switch hte n-gun kaba ai-fuse hpe bang na matu hpaji jaw da ai. MSD hte matut mahkai ai cable lapran na high-voltage matut mahkai ai lam gaw battery pack kata kaw interlock circuit langai mi hpe hpaw ra ai, dai matut mahkai ai lam hpe battery hparan ai ladat hku nna mu lu ai. Power battery pack a n-gun yawng hte n kaja ai n-gun yawng a matu n-gun kaba ai n-gun rawng ai n-gun rawng ai n-gun rawng ai n-gun rawng ai n-gun rawng ai n-gun rawng ai n-gun rawng ai n-gun rawng ai n-gun rawng ai n-gun rawng ai n-gun rawng ai n-gun rawng ai n-gun rawng ai (PCU) hte motor hpe Vehicle Control Unit (VCU Control Unit) hku nna mu lu ai.
Battery hpe hparan ai ladat gaw master-slave htingnu hpe hkap la ai. Madu uphkang hpung hte mayam uphkang hpung ni a lapran matut mahkai lam gaw CAN bus hku nna galaw ai re. Hkrang 9-3 hta battery system a kata na CAN bus hkrang hpe madun da ai.
Hkrang 9-3 kaw na mu lu ai hte maren, module langai hte langai hta Mayam Hkringmang Board langai mi hpe bang da ai. Slave Control Board hpe module hte hpawng de da ai majaw, platform ra kadawn ai lam ni hpe hkan sa lu na matu, n-gun rawng ai hku gram lajang lu ai, n-gun rawng ai module ni hpe galaw lu ai. Dai wan jak hkrang shapraw ai lam hta madung hku nna battery pack a high-voltage circuit hkrang shapraw ai lam hpe madung tawn nna, 2019 ning a rawt jat galu kaba lam ni hpe mung lawm ai.n-gun kaba ai wan n-gun shimlam, shawng-charge circuit, n-gun kaba ai-cable lata ai lam, MSD, hte ya aten na sensor ni hpe lang ai.
