Koj puas tau xav li cas aBMSpuas tuaj yeem tshawb xyuas qhov tam sim no ntawm lub lithium roj teeb pob? Puas muaj multimeter ua rau hauv nws?
Ua ntej, muaj ob hom roj teeb tswj Systems (BMS): ntse thiab kho vajtse versions. Tsuas yog cov ntse BMS muaj peev xwm xa cov ntaub ntawv tam sim no, thaum lub hardware version tsis.
A BMS feem ntau muaj kev tswj hwm kev sib koom ua ke (IC), MOSFET keyboards, ntsuas ntsuas tam sim no, thiab ntsuas ntsuas kub. Qhov tseem ceeb ntawm cov ntse version yog tswj IC, uas ua raws li lub hlwb ntawm kev tiv thaiv. Nws yog lub luag haujlwm rau kev saib xyuas lub sijhawm ntawm lub roj teeb tam sim no. Los ntawm kev sib txuas nrog lub ntsuas hluav taws xob tam sim no, tus tswj IC tuaj yeem tau txais cov ntaub ntawv hais txog lub roj teeb tam sim no. Thaum qhov tam sim no dhau qhov kev txwv kev nyab xeeb preset, tus tswj IC sai sai ua kev txiav txim siab thiab ua rau muaj kev tiv thaiv zoo.
Yog li, tam sim no nrhiav tau li cas?
Feem ntau, Hall effect sensor yog siv los saib xyuas tam sim no. Qhov no sensor siv kev sib raug zoo ntawm magnetic teb thiab tam sim no. Thaum tam sim no ntws los ntawm, ib tug magnetic teb yog generated nyob ib ncig ntawm lub sensor. Lub sensor outputs ib tug coj voltage teeb liab raws li lub zog ntawm magnetic teb. Thaum tus tswj IC tau txais cov teeb liab voltage no, nws suav qhov loj tam sim no siv cov algorithms sab hauv.
Yog tias qhov tam sim no tshaj qhov kev nyab xeeb ntawm preset, xws li overcurrent lossis luv luv tam sim no, tus tswj IC yuav ceev ceev tswj cov MOSFET keyboards txiav tawm txoj kev tam sim no, tiv thaiv ob lub roj teeb thiab tag nrho cov kab hluav taws xob.
Tsis tas li ntawd, BMS tuaj yeem siv qee qhov resistors thiab lwm yam khoom siv los pab saib xyuas tam sim no. Los ntawm kev ntsuas qhov hluav taws xob poob thoob plaws ib qho resistor, qhov loj tam sim no tuaj yeem suav.
Qhov no series ntawm complex thiab meej Circuit Court tsim thiab tswj mechanisms yog tag nrho cov tsom rau kev soj ntsuam cov roj teeb tam sim no thaum tiv thaiv overcurrent xwm txheej. Lawv ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev nyab xeeb ntawm kev siv roj teeb lithium, txuas ntxiv roj teeb lub neej, thiab txhim kho kev ntseeg tau ntawm tag nrho cov roj teeb, tshwj xeeb hauv LiFePO4 daim ntawv thov thiab lwm yam BMS series systems.
