Stationary and mobile energy storage system Drive Power Solution from SEW Eurodrive

The stationary and mobile Drive Power Solution energy storage system from SEW-Eurodrive stores electrical energy directly in the drive application and releases it again immediately when required. The storage system can be scaled to suit the application and project. It consists of an energy coupler, the energy management system and innovative storage units based on double-layer capacitors. The energy management system is an integral part of the 'Movi-PLC' local drive control system. It calculates the amount of energy and power required in advance, depending on the driving cycle. This data is used to control the energy coupler, which uses DC/DC conversion to determine the charging and discharging cycle of the storage system and monitors it at the same time. In stationary drives with a continuous mains supply, the storage system is used in power mode. According to the manufacturer, applications with a cyclically changing load profile save up to 48% of the energy requirement by storing regenerative braking energy and feeding it back to the drive during motor operation. In mobile applications, industrial trucks or shuttle vehicles can absorb energy in the shortest possible time by means of energy traces via contact-based or inductive energy transfer while on the move in order to then navigate through space independently of fixed paths.
