Edison Motors and Semisysco will collaborate in the sales of electric trucks and buses, the pair said on Friday.
They will use their motor, battery management system, and light car body technologies to expand their portfolio in electric vehicles and SUVs, they said.
They will also continue advance the light electric car model EV Z.
Edison Motors said it was the largest supplier electric buses to Seoul. It will launch a 1-tonne electric truck this year to expand the market for electric vehicles further, the company said.
Semisysco was founded in 2000 and offers semiconductor and OLED solutions. It launched its first electric vehicle EV Z, a two-seater, last year.
