Mulithium bhatiri masisitimu, iko kurongeka kweSOC (State of Charge) chiyero chakakosha cheBattery Management System (BMS) kuita. Pasi penzvimbo dzakasiyana dzetembiricha, basa iri rinowedzera kunetsa. Nhasi, tinonyura mune yakapusa asi yakakosha tekinoroji pfungwa-zero-drift current, iyo inokanganisa zvakanyanya SOC fungidziro yechokwadi.
Chii chinonzi Zero-Drift Current?
Zero-drift ikozvino inoreva chiratidzo chenhema chazvino chinogadzirwa muamplifier wedunhu kana painezero input current, asi nekuda kwezvinhu zvakadaikuchinja kwekushisa kana kusagadzikana kwekupa magetsi, iyo static inoshanda nzvimbo yeamplifaya inochinja. Shanduko iyi inokwidziridzwa uye inoita kuti chinobuda chisuduruke kubva pane chayakada kuti zero kukosha.
Kuti uzvitsanangure zviri nyore, fungidzira chiyero chekugezera chedhijitari chinoratidza5 kg yehuremu munhu asati ambotsika pairi. “Chipoko” uremu ihwohwo hwakaenzana ne zero-drift current — chiratidzo chisipo.
Nei Iri Dambudziko reLithium Bhatiri?
SOC mu lithium mabhatiri anowanzo kuverengerwa uchishandisacoulomb counting, iyo inobatanidza ikozvino nekufamba kwenguva.
Kana zero-drift ikozvino irizvakanaka uye zvinopfuurira, zvingadarokusimudzira zvenhema SOC, kunyengedza sisitimu kuti ifunge kuti bhatiri rinochajiswa kupfuura zvariri chaizvo-zvichida kubvisa kuchaji nguva isati yakwana. Ukuwo,negative driftzvinogona kutungamirira kuyakaderera SOC, zvichikonzera kudzivirira kwekutanga kubuda.
Nekufamba kwenguva, izvi zvikanganiso zvakawedzera zvinoderedza kuvimbika uye kuchengetedzeka kwebhatiri system.
Kunyangwe zero-drift ikozvino isingakwanise kubviswa zvachose, inogona kudzikiswa zvinobudirira kuburikidza nemusanganiswa wenzira:
- Hardware optimization: Shandisa yakaderera-kudonha, yakakwirira-chaiyo op-amps uye zvikamu;
- Algorithmic muripo: Shandura zvine simba kudhirivha uchishandisa chaiyo-nguva data senge tembiricha, voltage, uye zvazvino;
- Thermal management: Gadzirisa marongerwo uye kupisa kupisa kuderedza kupisa kusaenzana;
- High-precision sensing: Kuvandudza iko kurongeka kweakakosha parameter yekuona (sero voltage, pack voltage, tembiricha, ikozvino) kudzikisa fungidziro zvikanganiso.
Mukupedzisa, kunyatsojeka mune yega microamp inoverengera. Kubata zero-drift ikozvino inhanho yakakosha yekuvaka yakangwara uye yakavimbika bhatiri manejimendi masisitimu.
