Muyezo wolondola wapano mu Battery Management Systems (BMS) umatsimikizira malire achitetezo a mabatire a lithiamu-ion pamagalimoto amagetsi ndi malo osungira mphamvu. Kafukufuku waposachedwa wamakampani akuwonetsa kuti kupitilira 23% ya zochitika zotentha za batri zimachokera ku kusuntha kwa ma calibration m'mabwalo achitetezo.
Kuwongolera kwaposachedwa kwa BMS kumatsimikizira kuti pakufunika kuti pakhale zochulukira, kutulutsa kwambiri, komanso chitetezo chafupipafupi monga momwe zidapangidwira. Kulondola kwa kuyeza kumatsika, mabatire amatha kugwira ntchito mopitilira mazenera otetezedwa - zomwe zitha kupangitsa kuti kutentha kutha. Njira ya calibration imaphatikizapo:
- Kutsimikizika kwa BaselineKugwiritsa ntchito ma multimeter ovomerezeka kuti mutsimikizire mafunde atsatanetsatane motsutsana ndi kuwerenga kwa BMS. Zida zoyezera magawo a mafakitale ziyenera kukwaniritsa ≤0.5% kulolerana.
- Kulipira ZolakwaKusintha ma coefficients a firmware a board board pamene kusagwirizana kumaposa zomwe wopanga amapanga. BMS yamagiredi yamagalimoto nthawi zambiri imafuna ≤1% kupatuka pano.
- Kutsimikizika kwa Stress-TestKugwiritsa ntchito mizere yoyezera katundu kuchokera ku 10% -200% mphamvu yovotera kumatsimikizira kukhazikika kwanthawi yayitali pansi pa zochitika zenizeni.
Dr. Elena Rodriguez, wofufuza za chitetezo cha batri ku Munich Technical Institute anati: “BMS yosawerengeka ili ngati malamba othyoka osadziwika bwino. "Kusintha kwamakono kwapachaka kuyenera kukhala kosagwirizana ndi mapulogalamu amphamvu kwambiri."
Njira zabwino kwambiri ndi izi:
- Kugwiritsa ntchito malo oyendetsedwa ndi kutentha (± 2 ° C) pakuwongolera
- Kutsimikizira kuyanjanitsa kwa masensa a Hall musanasinthe
- Kulemba zololera za pre/post-calibration for audit trails
Miyezo yachitetezo chapadziko lonse lapansi kuphatikiza UL 1973 ndi IEC 62619 tsopano ikulamula kuti ma calibration ajambule ma batire a grid-scale. Ma labu oyesa a gulu lachitatu akuwonetsa ziphaso zofulumira 30% zamakina omwe ali ndi mbiri yotsimikizika yotsimikizika.
