Ụlọ ọrụ na-akwụ ụgwọ ọha na eze na-aga n'ihu na elekere-kilowatt (ma megidere oge) ịgba ụgwọ, na ndị na-emepụta ga-achọwanye ka ha tinye mita DC agbaziri agbaziri n'ọdụ ụgbọ mmiri ha.
Iji gboo mkpa a, ọkachamara n'ịle eletrik LEM ewebatala DCBM, mita DC bidirectional edepụtara UL maka chaja EV ngwa ngwa.
DCBM “ga-enyere ndị na-eme ụlọ ọrụ chaja EV aka mee ngwangwa asambodo ha maka ihe achọrọ DC metering na-eso asambodo nnwale na Evaluation Professional/National Type Evaluation Program (CTEP/NTEP),” LEM kwuru."DCBM ga-eme ka usoro ndị na-emepụta ihe dị mfe iji ruo eruo ebe ha na-akwụ ụgwọ maka asambodo UL na, maka udo nke uche, ga-enyocha nyocha ọhụrụ kwa nkeji."
Mita ọhụrụ ahụ nwere ike ileba anya ugbu a, voltaji, okpomọkụ na ojiji ike, ma ejiri nchekwa data na mgbanwe n'uche mee ya.DCBM 400/600 na-akwado ụkpụrụ UL 61010 na UL 810 na ngalaba FTRZ maka ngwa EV.Iji nweta asambodo a, mita ahụ ga-agafe ule mkpuchi mkpuchi siri ike, nnwale okpomọkụ nke ihe niile mejupụtara ya na mgbakọ dị iche iche, nnwale maka nchebe megide ujo eletrik, ịdịte aka nke ule akara, ule oke okpomọkụ akụrụngwa na iguzogide ule ọkụ/ọkụ ọkụ.
Emebere DCBM maka chaja DC sitere na 25 kW ruo 400 kW, wee jikọta usoro ịgba ụgwọ mbinye aka dị ka usoro Open Charge Metering Format (OCMF) siri dị.Enwere ike megharịa ya ka ọ bụrụ ọdụ ụgbọ mmiri dị ugbu a, ma nwee ihe ọ̀tụ̀tụ̀ enwere ike iji ya mee ihe n'ụdị ọ bụla nke ụlọ ọdụ chaja.Ọ ziri ezi na okpomọkụ nke -40° ruo 185 Celsius, ma nwee ihe mkpuchi IP20.
Atụmatụ ndị ọzọ gụnyere nkwado Ethernet na mita ike ike bidirectional, nke na-eme ka ọ dakọtara na ngwa V2G (ụgbọ-na-grid) na V2X (ụgbọ-na-ihe ọ bụla).
"Azụmaahịa US na Canada maka EVs na-aga n'ihu na-agbasawanye mana enwere ike igbochi uto a site n'inweta ohere zuru oke n'ọdụ ụgbọ mmiri DC ngwa ngwa," Claude Champion, Onye isi njikwa na LEM USA kwuru."LEM ghọtara kpọmkwem ihe mpaghara ahụ chọrọ ma soro ndị na-emepụta EVCS na ndị na-arụ ọrụ na-arụkọ ọrụ mgbe ha na-emepụta ngwọta dị ka DCBM 400/600."
