Gupima neza ubushyuhe muri sisitemu yo gucunga bateri (BMS) bigena imipaka y'umutekano wa bateri za lithiamu-iyoni ku modoka zikoresha amashanyarazi no mu bubiko bw'ingufu. Ubushakashatsi buherutse gukorwa mu nganda bugaragaza ko hejuru ya 23% by'impanuka z'ubushyuhe bwa bateri zituruka ku guhindagurika kw'ingufu mu miyoboro y'uburinzi.
Gupima ubushyuhe bwa BMS bitanga ubushobozi bwo kurinda umuriro mwinshi, gusohora umuriro mwinshi, no kurinda amashanyarazi make nk'uko byagenwe. Iyo uburyo bwo gupima bwagabanutse, bateri zishobora gukora hanze y'amadirishya akoreramo neza - bishobora gutuma ubushyuhe bugenda nabi. Uburyo bwo gupima bukubiyemo:
- Igenzura ry'ibanzeGukoresha multimetero zemewe kugira ngo harebwe imiyoboro y'amashanyarazi ijyanye n'ibipimo bya BMS. Ibikoresho byo gupima by'urwego rw'inganda bigomba kugera ku buremere bwa ≤0.5%.
- Indishyi z'amakosaGuhindura coefficients za firmware y'ikibaho cyo kurinda iyo ibitandukanye birengeje ibisabwa n'uruganda. BMS yo mu rwego rw'imodoka ubusanzwe ikenera ≤1% by'ihindagurika ry'umuriro.
- Kugenzura ikizamini cy'umuvudukoGukoresha imigendekere y’umutwaro wifashishijwe mu buryo bwa "simulated load cycles" kuva ku bushobozi bwa 10%-200% byemeza ko ubushobozi bwo gupima buhamye mu bihe nyabyo.
"BMS idakozwe mu buryo busanzwe ni nk'imikandara y'umutekano ifite aho icika itazwi," Dr. Elena Rodriguez, umushakashatsi ku mutekano w'amabateri mu kigo cy'ikoranabuhanga cya Munich, agira ati: "Gupima buri mwaka ntibikwiye kuganirwaho ku mikoreshereze y'amashanyarazi menshi."
Uburyo bwiza bwo gukora ibintu burimo:
- Gukoresha ibidukikije bigenzurwa n'ubushyuhe (± 2°C) mu gihe cyo gupima
- Gusuzuma uburyo sensor ya Hall ihagaze mbere yo kuyikosora
- Gutanga inyandiko ku buryo bwo kwihanganira mbere/nyuma yo gupima inzira z'igenzura
Amabwiriza mpuzamahanga y’umutekano arimo UL 1973 na IEC 62619 ubu ategeka inyandiko zo gupima ku mikoreshereze ya bateri ku rwego rwa grid. Laboratwari zo gupima zikora ku rundi ruhande zigaragaza ko zihuta ku kigero cya 30% ku buryo sisitemu zifite amateka yo gupima ashobora kwemezwa.
