Ulalo Wofunika Wolumikizira Mabatire Amphamvu Ndi Magalimoto Amagetsi - BMS (Battery Management System)-1

 

1.Kodi BMS Battery Management System ndi chiyani?

BMS Battery Management System imagwiritsidwa ntchito makamaka pakuwongolera ndi kukonza ma batri mwanzeru, kupewa kuchulutsa komanso kutulutsa mabatire mopitilira muyeso, kukulitsa moyo wa batri, ndikuwunika momwe mabatire alili.

2.Zithunzi za BMS

BMS imapangidwa makamaka ndi BMU master controller, CSC sub-controller, CSU balancing module, HVU high-voltage controller, BTU batire chizindikiro unit unit, ndi GPS kulankhulana module.

3.Mawonekedwe amtundu wa BMS

BatteryManagement System (BMS) ndi gawo lofunikira pamagalimoto amagetsi ndi ma batire ena. Ili ndi udindo woyang'anira ndikuwongolera momwe batire ilili kuti iwonetsetse kuti ikugwira bwino ntchito. Kuzungulira kwa moyo wa aBMSzitha kugawidwa m'magawo angapo:

  • Gawo la mapangidwe: Pagawo la mapangidwe a BMS, ntchito ndi kasinthidwe ka BMS kuyenera kutsimikiziridwa kutengera zinthu monga mtundu wa batri, mawonekedwe ogwiritsira ntchito, ndintchito zofunika. Gawoli limafuna kufufuza kwakukulu ndi kuyesa kuonetsetsa kutiBMS kupangaimakwaniritsa zosowa za batire.

 

  • Gawo Lopanga: Panthawi yopangira BMS, magawo osiyanasiyana a BMS ayenera kupangidwa molingana ndi zomwe amapangidwira ndikusonkhanitsidwa ndikuyesedwa. Gawoli limafuna kuwongolera kokhazikika kuti zitsimikizire kuti mtundu wa BMS ndi magwiridwe ake akukwaniritsa zofunikira za kapangidwe kake.

 

  • Kukhazikitsa ndi kukonza zolakwika: Pa nthawi yaKukhazikitsa kwa BMSndidebugging stage, BMS iyenera kuyikidwa mu batri ndi kuyesedwa ndi kusinthidwa. Gawoli limafunikira chisamaliro chachikulu komanso kulondola kuti kuyika ndi kukonza BMS sikuwononge batri kapena kusokoneza magwiridwe ake.

 

  • Gawo la ntchito ndi kukonza: Pa nthawi ya BMS yogwira ntchito ndi kukonza, kuyang'ana nthawi zonse ndi kukonza kuyenera kuchitidwa kuti zitsimikizidwe kuti BMS ikugwira ntchito bwino. Gawoli limafuna kujambula ndi kusanthula deta kuti mudziwe mwamsanga ndi kuthetsa mavuto ndi kukweza ndi kusunga BMS.

 

  • Kupuma pantchitondisiteji yokonzanso: Panthawi yopuma pantchito ndi kukonzanso BMS, BMS iyenera kusinthidwa kapena kusinthidwa kutengera moyo wa batri komanso momwe batire imagwirira ntchito. Gawo ili likufunikakusanthula detandi kuunika kuti muwone ngati BMS ikufunika kusinthidwa kapena kusinthidwa ndi momwe mungasinthire kapena kusintha BMS.

BMS imayikidwa mu paketi ya batri yamphamvu

4.Ntchito zazikulu za mapulogalamu a BMS

Ntchito yoyezera

(1) Muyezo wa zidziwitso zoyambira: kuyang'anira mphamvu ya batri, chizindikiro chapano, ndi kutentha kwa batire. Ntchito yofunikira kwambiri ya kasamalidwe ka batri ndikuyesa voteji, panopa, ndi kutentha kwa maselo a batri, omwe ndi maziko a mawerengedwe onse apamwamba ndi ndondomeko yoyendetsera kayendetsedwe ka batri.

(2) Kuzindikira kukana kwa insulation: Dongosolo lonse la batri ndi makina othamanga kwambiri amayenera kuyesedwa kuti atsekeredwe ndi kasamalidwe ka batire.

(3) High-voltage interlock discovery (HVIL): amagwiritsidwa ntchito kutsimikizira kukhulupirika kwa dongosolo lonse lapamwamba lamagetsi. Pamene umphumphu wa dera la high-voltage system wawonongeka, njira zotetezera zimatsegulidwa.

Kuyerekeza ntchito

(1) Kuyerekeza kwa SOC ndi SOH: gawo lofunikira komanso lovuta kwambiri

(2) Kulinganiza: sinthani kusamvana kwa SOC x pakati pa ma monomers kudzera pagawo losanja.

(3) Kuchepetsa mphamvu ya batri: mphamvu yolowera ndi kutulutsa batire imakhala yochepa pa kutentha kosiyanasiyana kwa SOC.

Ntchito zina

(1) Kuwongolera: kuphatikiza main +, main-, charger relay +, charger relay -, pre-charging relay

(2) Kuwotcha kutentha

(3) Ntchito yolankhulana

(4) Kuzindikira zolakwika ndi alamu

(5) Opaleshoni yolekerera zolakwika
