CAN bus matut mahkai lam gaw hpa rai ta?
Bus Bus hte matut mahkai ai lam
Controller Area Network (CAN) gaw, tengman ai- aten hta jai lang ai serial matut mahkai lam hpe hkan sa ai bu hpun langai mi re. Dai gaw, twisted{2}}}}}air cable hpe lang nna signal ni hpe htawn tsun lu ai. Shi a bungli galaw ai lam grai law ai, kam hpa mai ai lam grai law ai, tengman ai- aten grai law ai majaw, mungkan hta grau nna jai lang ai fieldbus langai mi tai wa sai. CAN matut mahkai lam gaw ya aten hta battery hparan ai ladat (BMS) hta madung matut mahkai ladat rai nga ai. Dai hpe mungdan kata hte mungkan ting hta, mungdan kata hte mungkan ting na BMS data matut mahkai ai madang ni hta mung, hpaga lam hte seng ai wan jak BMS masa law law hta grai law hkra hkap la nga ai. RS232 hte RS485 bus ni hpe mung BMS masa kata na kata lam matut mahkai lam nkau mi hta lang ai.
Hkrang 8-26 hta san seng ai wan jak mawdaw a matu battery hparan ai ladat hpe madun da ai. Dai ni hta, RS232 gaw madung hku nna, main control board hte host computer (sh) lata hte lang ai jak lapran na matut mahkai lam hpe chye na la nna, main control board hte detection board a parameter amyu myu hpe masat da ai lam hpe ngut kre hkra galaw ya ai; RS485 gaw madung hku nna, madung hkang zing ai board hte sawk sagawn hpung lapran na matut mahkai lam hpe chye na nna, master hte mayam board lapran na battery data hte detection board parameters ni hpe htawt sit ai lam hpe ngut kre hkra galaw ai; CAN matut mahkai lam hpe CAN1 hte CAN2 ngu ai lam lahkawng hku garan nna tsun ai. CAN1 gaw madung hku nna mawdaw main controller hte matut mahkai nna, mawdaw ting ra ai battery{9}} hte seng ai shiga ni hpe ngut kre hkra galaw ai; CAN2 gaw madung hku nna mawdaw arung arai hte mawdaw n re ai charger ni hte matut mahkai nna, battery data ni hpe garan gachyan ai lam hpe chye na na matu hte charge hpe hkang na matu data npawt nhpang jaw ai.
Mawdaw galaw ai ladat hta battery hparan ai ladat (BMS) a hkrang hpe sumla 8-27 hta madun da ai. BMS a central control module gaw CAN1 bus hku nna mawdaw hkang ai hte mawdaw hkang ai wa hpe tengman ai- aten hte ra kadawn ai battery status hte seng ai shiga ni hpe matut mahkai ya ai, dai gaw bungli galaw ai bungli ni hpe atsawm sha ngut kre hkra galaw lu na matu hte battery prat hpe galu kaba wa hkra grau nna myit sawn sumru mai ai hkang zing ladat ni hpe hkap la lu na matu galaw ya ai. Dai hte maren, BMS (central control module) gaw, n-gun ja ai CAN2 bus hku nna, onboard monitoring system de, battery pack shiga ni hpe hkrak tup tsun dan ai, battery status data hpe madun dan ai hte, mara shagun ai lam ni hpe jaw ya ai majaw, battery hpe gram lajang na matu hte galai na matu npawt nhpang langai mi hpe jaw ya ai.
Hkyak hkyak charge galaw ai ladat hta BMS a hkrang hpe sumla 8-28 hta madun da ai. Dai charger hpe wan jak hte hkum hkrang hku matut da ai. Ndai aten hta, ntsa na high{5}}}speed CAN2 Bus gaw charger node hte matut mahkai nga ai, kaga lam ni gaw n galai shai ai sha naw nga ai. charger gaw, aten dep battery status hpe chye na na matu, manu jahpu hpe shim lum ai hku charge galaw lu na matu, charge ladat hpe gram lajang na matu, tsaw ai{7}}speed CAN2 bus hpe lang ai.
