ENERGY SUPPLY

摘要

The invention relates to a stationary energy store (105) for temporarily storing electric energy in a stationary energy supply network (120) for a vehicle (110) that can be electrically driven, comprising a stationary storage unit (170), a first buck converter (175) for charging the stationary storage unit (170), a first boost converter (180) for discharging the stationary storage unit (170), a second boost converter (185) for charging the stationary storage unit (170), and a second buck converter (190) for discharging the stationary storage unit (170). An energy system (100) comprises the stationary energy store (105) and the vehicle (110) that can be electrically driven, wherein the vehicle (110) comprises a mobile energy store (115) for storing electric drive energy, and the mobile energy store (115) comprises a mobile storage unit (265) configured to be charged from the stationary storage unit (170).
