Abstract: A method for predicting a state-of-power, SoP, of an electric energy storage system, ESS, comprising at least two battery units electrically connected in parallel. The method includes obtaining operational data from the at least two battery units of the ESS during operation of the ESS; computing the state-of-power of the ESS based on the obtained operational data and by using an algorithm based on a system-level model of the ESS, wherein the system-level model of the ESS takes into account on one hand each one of the at least two battery units of the ESS, and on the other hand at least one electrical connection between the at least two battery units, and wherein the system-level model of the ESS further takes into account a dynamic parallel load distribution between the at least two battery units.

Abstract: A juice extractor and a feeding apparatus thereof are provided. The feeding apparatus includes a feed channel, a feed body connected to an upper port of the feed channel, and a cover plate assembly. The cover plate assembly includes a cover plate and an accommodating cavity with a large capacity. A shape of the cover plate matches an inner wall of the feed body and the cover plate is provided with a feed inlet, and the cover plate is rotatably provided on the inner wall of the feed body. The accommodating cavity with a large capacity is provided on a top surface of the cover plate, and has a sectional area greater than an area of the feed inlet, and is formed by an enclosure plate that surrounds the feed inlet. Upon inversion of the cover plate assembly, an opening of the accommodating cavity with a large capacity can be made to face the feed channel, and fruits and vegetables contained in the accommodating cavity with a large capacity are put in the feed channel.
