A key core know-how of OBRIST Powertrain lies in the design and development of application-oriented HV and LV Li-ion battery systems. It has developed its own highly efficient and cost-optimized solution for use in a serial hybrid vehicle. In general, OBRIST relies on cylindrical 18650 cells. The main advantages of this cell technology are the continuously falling costs (high sales market, for example, in construction machinery and entertainment electronics), the interchangeability (due to continuous development over higher capacities and discharging rates) and manufacturer independence. In addition to battery variants with 18650 cells, concepts with pouch and prismatic cells were also developed through internal and customer projects. OBRIST, as a thermal management expert, also develops cooling concepts at the cell, module and battery level and integrates these into the overall vehicle thermal management concept.
