Fremgangsmate og system for a mate elektrisk energi til en forsyningsbuss til et elektrisk kjoretoy, opptaksmedium og kjoretoy for fremgangsmaten

摘要

The method involves controlling step-up rectifier for supplying a DC bus with rectified and increased AC voltage delivered by a terminal, when DC voltage on the bus attains 70 percentage of a maximum intermediate voltage. The disconnection of the bus from the terminal is controlled when the DC voltage on the bus attains 70 percentage of a nominal voltage. The closing of the disconnecting switch is then controlled for connecting the bus to another terminal without passing through a precharge circuit. Independent claims are also included for the following: (1) an information recording medium comprising instructions for executing charging method (2) a DC bus charging system (3) an electric vehicle comprising a DC bus charging system.
