Gukoresha umuringa mu binyabiziga bishya

Nk’uko imibare yaturutse mu ishyirahamwe mpuzamahanga ry’umuringa ibivuga, mu mwaka wa 2019, impuzandengo ya kg 12,6 y’umuringa yakoreshejwe kuri buri modoka, ikiyongeraho 14.5% kuva kuri kg 11 mu 2016. Ubwiyongere bw’ikoreshwa ry’umuringa mu modoka ahanini buterwa no gukomeza kuvugurura ikoranabuhanga ryo gutwara ibinyabiziga, bisaba ibikoresho byinshi bya elegitoroniki n’itsinda ry’insinga.

Gukoresha umuringa ibinyabiziga bishya byingufu biziyongera mubice byose hashingiwe kumodoka ya moteri yaka imbere. Umubare munini wamatsinda arasabwa imbere muri moteri. Kugeza ubu, imodoka nyinshi zinganda zikora ingufu ku isoko zihitamo gukoresha PMSM (moteri ihoraho ya magnetiki). Ubu bwoko bwa moteri bukoresha kg 0.1 yumuringa kuri kilowati, mugihe imbaraga zimodoka nshya ziboneka mubucuruzi ziri hejuru ya kilowati 100, naho gukoresha umuringa wa moteri byonyine birenga kg 10. Mubyongeyeho, bateri nibikorwa byo kwishyuza bisaba umuringa munini, kandi gukoresha umuringa muri rusange biziyongera cyane. Abasesenguzi ba IDTechEX bavuga ko ibinyabiziga bivangavanze bikoresha kg 40 z'umuringa, ibinyabiziga bicomeka bikoresha kg 60 z'umuringa, naho imodoka zikoresha amashanyarazi zikoresha kg 83 z'umuringa. Imodoka nini nka bisi z'amashanyarazi zisukuye zisaba 224-369 kg z'umuringa.
