During this session, the Preh team will explore hit pioneering HV Booster that enables 800 V electric vehicles to charge at 400 V charging stations, in series since 2019 with Porsche Taycan.

Preh HV Booster features a resonant converter that “boosts” 400 V electrical power to 800 V allowing, with its 150 kW nominal power, the charging of 80% of the battery in just over 35 minutes. Its special topology achieves a very high efficiency (over 97%) and the in-house customized software guarantees a full interoperable use at all DC charging stations available worldwide.

Dr. Edoardo Morra is Head of Preh E-Mobility Product Management and Business Development works in close contact with Preh E-Mobility Customers worldwide, supporting innovative product developments in the area of Battery Management Systems and Power Electronics.

Martin Estala is Engineering Manager at Preh Novi, Michigan, responsible for all eMobility engineering activities for US customers.
