E hlahisa phetoho ea phetoho ea Boemo ba 1, 2, le 3 ea Suzhou Yihang Electronic Science and Technology Co., Ltd., moetsi ea ka sehloohong, mofani oa thepa le feme e thehiloeng Chaena. Ha lefatše le ntse le amohela likhetho tse tšoarellang tsa lipalangoang, litsamaiso tsa rona tsa morao-rao tsa ho tjhaja li hlakisa bocha ho ba bonolo, ho sebetsa hantle, le ho ts'epahala ha ho tjhaja koloi ea motlakase. Ka litharollo tsa rona tsa ho tjhaja Level 1, 2, le 3, re khotsofatsa litlhoko tsa mosebelisi e mong le e mong oa EV, ho netefatsa liphihlelo tse se nang moeli le ho fokotsa linako tsa ho tjhaja. Lijaja tsa rona tsa Level 1 li fana ka tharollo e theko e tlaase bakeng sa ho tjhaja lapeng, e lumellang beng ba EV ho hokela motlakase ka har'a motlakase o tloaelehileng.
