Shared Charging

SAL researches and develops cost-optimized DC/DC charger hardware for charging of multiple electric vehicles sequentially. This so-called “charging column front-end” is the interface module between the core power distribution system (DC bus) and a number of BEVs. It is also the front-end to the user.

The so-called charging column must:

• take available power from the core system and route and pass a defined power level, based on a top level energy management system, to one of the connected BEVs.
• enable BEV selection and switching during the charging procedure under load
• show highest efficiency and an overall loss of <1% (includes DC/coupling and power multiplexer)
• implement local safety circuitry,
• implement accurate power measurement for billing services,

SAL is in particular responsible for the DCDC converter and its system integration with other power electronic and safety subsystems. A high efficient converter will be main part of the research activities, and finally being packaged for easy system integration.
