Battery pilot line no yɛ abusuabɔ titiriw a ɛda laboratory R&D ne akɛse-scale mass production ntam. Ne botae titiriw ne sɛ ɛbɛhwɛ sɛ nhyehyɛe no betumi ayɛ yiye, agyina pintinn, ne sikasɛm wɔ ɔkwan ketewaa bi so, na ato fapem ama nneɛma akɛse-ayɛ. Ɛsɛ sɛ pilot line nhyehyɛɛ no kari pɛ wɔ mfiridwuma mu nokwaredi ne ɛka a wɔbɔ sohwɛ mu de hwɛ hu sɛ data a wotumi de ho to so na ɛma wonya nnyinaso ma akyiri yi production line optimization.
