MORE ENERGY – LESS WEIGHT

OBRIST Powertrain batteries for PHEV and BEV applications are designed to fulfill customer expectations mostly related to increased specific energy and reduced costs. The most significant factors are the low costs and flexible battery pack design using cylindrical or pouch cells. Our module aluminum housing works as a temperature heat sink, eliminating internal heat exchangers. In addition, the whole system was designed with a strong focus on excellent component integration to reduce complexity and material costs. The battery architecture has been tailored to automated production to achieve an extra level of reliability.
