A power supply (1) is for an electrical load in the form of a Notebook computer (2). Power supply (1) includes first terminals (3, 4) which extend from computer (2) for releasably electrically connecting with a first energy storage device in the form of battery (5) during a first interval. A second energy storage device, in the form a second battery (not shown), releaseably electrically connects with terminals (3, 4) during a second interval spaced apart from the first interval. This allows power to be supplied to the load during those intervals. A capacitive energy storage device, designated generally by reference numeral (6), supplies power to the load during a third interval that spans the spacing between the first and the second intervals.

La présente invention concerne une alimentation (1) destinée à une charge électrique sous forme d'ordinateur portatif (2). Cette alimentation (1) comprend des premiers terminaux (3, 4) qui partent de l'ordinateur (2) pour se connecter électriquement et de manière amovible à un premier dispositif de stockage d'énergie sous forme de batterie (5), dans un premier intervalle. Un second dispositif de stockage d'énergie, sous forme de seconde batterie (non représentée), est connecté électriquement de manière amovible avec les terminaux (3, 4), dans un deuxième intervalle espacé du premier intervalle. Ceci permet d'alimenter la charge dans ces deux intervalles. Un dispositif capacitif de stockage d'énergie, généralement représenté par le numéro de référence (6), alimente la charge dans un troisième intervalle qui couvre les premier et second intervalles.
