Electric lirthei te hian thianghlim leh boruak humhalh hi an ngaihtuah fo thin a ni. Energy crisis leh oil man sang chho zel nen hian electric lirthei hi a hmangtute chuan an duh zual hle. Electric lirthei hi a tlangpuiin lithium battery hmanga siam a ni a, cell pakhat tam tak chu series-ah an inzawm khawm a, power source atan battery pack an siam a ni. Mahse, series cell tinte characteristic chu a inang tlang vek tur a nih loh avangin, charging leh discharging speed te chu current inang hnuaiah a danglam dawn a ni. Balancing intervention tih a nih loh chuan battery life chu nasa takin a tawi dawn a, chuvangin cell tinte state leh total voltage chu real time-a enfiah a ngai a ni. Total current, battery charge leh discharge equalization dinhmun, leh charge leh discharge balance, equilibrium state pawh real time-a hmuh tur a nih avangin electric vehicle Battery Energy Management System (EMS) a awm bawk. Practice chuan EMS hian electric lirthei battery life a ti rei thei tih a finfiah a, electric lirtheia management system pawimawh tak a ni tih a finfiah bawk.
EMS-ah hian information lakkhawmna module, charge leh discharge equalization module, information centralized processing module, leh display module te a awm ber a ni. Figure 1-ah hian Self-Developed Electric Vehicle Battery Energy Management System (EMS) structural diagram a awm a. Information acquisition module hian a bul berah chuan battery pack real-time collection leh battery pakhata voltage, temperature, current leh status dangte a tifel a, battery pawh real time-in a enfiah bawk. Equalization module hawn leh khar theihna tur a ni. Equalization module hian a bik takin battery characteristics danglamna a compensate a, acquisition module-in information a khawn dan a zirin battery dinhmun a tichiang a, battery pakhatah charge leh discharge equalization a ti bawk a, chu chuan state characteristics inmil tak a nei thei a ni. Information centralized processing module hian data khawlkhawm (SOC, etc. ang chi) te chu process, analysis, leh chhut a, equalization module hnathawh enkawl te, control te, display module nena inbiak te, system pum puia role play te a ni. Mihring pakhat chauh-computer interaction interface a nih angin, display module hian a hmangtu hnenah data leh device status zawng zawng chu real time-in a keng tel vek mai bakah, a hmangtu chu battery status leh EMS work effect chu a hmuh theihin a hmu thei bawk a, a hmangtu tan EMS control communication a pe bawk. Interface hian user chu parameters set theihna a siam a, EMS te working status a thlak theih nan real-time supervision leh control a nei thei bawk.
Display module a awm loh chuan miten battery leh EMS information an hmu thei lo. EMS alarm emaw prompt information emaw chu customer hnenah hriattir theih a ni lo. Alarm status thenkhat chu a hun takah process theih a ni lo a, chu chuan battery a tichhia ang a, chu chuan electric vehicle control a hloh phah ang. accident na tak a ni ta. Chutiang bawkin customer te pawhin an dinhmun azirin EMS an adjust leh control thei lo a, EMS role pawh an play kim thei lo bawk. Display module-a mihring-computer interaction function hi EMS-a thil pawimawh tak a ni tih a hriat theih. Display module-in a mamawh function atanga touch screen hmuh hi duhthlan tur tha tak a ni. Mahse, market-a touch screen lei a nih chuan, display content chauh ni lovin, touch screen-a display function-in a tihkhawtlai mai bakah, display design-a flexibility leh display quality a nghawng bawk a, market-a touch screen man a sang tlangpui a, hei hian product-ah hian a tam zawk a belhchhah a ni. Cost, chu chuan rinhlelh rual lohvin products market competitiveness a ti tlem hle ang. Hetiang dinhmun a\\ang hian he paper hian control core atan STM32F103 microcontroller hmanga LCD touch screen hman tlanglawn tak design scheme a rawt a ni.
