EV battery system R&D, custom design, production and maintenance
PMGROW has produced custom battery packs for various EV platforms from class 7-8 buses and trucks to personal mobility vehicles
for 10+ years. Among others, battery packs for large- and medium-sized electric buses are main products today.
PMGROW produces and supplies custom battery packs that are optimized for each EV. Packs are available
with every cell form factor: pouch, prismatic and cylindrical.
