The invention relates to a method for operating a supercharger having an electrically operable compressor (8,8',62) in an engine system (1) having an internal combustion engine (2). The method comprises the following steps: determining (S2,S3,S4;S12,S13,S14) a particular system state when the internal combustion engine (2) is shut off; forming (S5;S15) a purge path between an air supply system (4) and an exhaust gas system (5) of the engine system (1); activating (S6;S16) the electrically operable compressor (8,8',62) as a function of the determined system state. 本发明涉及种用于运行在具有燃烧发动机（2）的发动机系统（1）中的、具有可电运行的压缩机（8，8'，62）的增压装置的方法，具有以下步骤：-确定（S2，S3，S4；S12，S13，S14）在停止的燃烧发动机（2）下的确定的系统状态；-形成（S5；S15）在发动机系统（1）的空气供给系统（4）和废气系统（5）之间的冲洗路径；-依据被确定的系统状态激活（S6；S16）可电运行的压缩机（8，8'，62）。
