Layered equalizing circuit system based on series battery stack and hybrid control method

The invention discloses a layered equalizing circuit system based on a series battery stack and a hybrid control method, and belongs to the technical field of battery energy storage systems. A bottom layer of the architecture adopts an adjacent cell-cell (C2C) structure, and is divided into different battery packs. A top layer adopts a transformer coupled multi-directional multi-port converter, and bidirectional energy flow among arbitrary battery packs of the bottom layer is realized. The layered architecture can reduce the amount of equalizing circuits working simultaneously, so that the repeated charging and discharging problem of the batteries in the equalizing process is avoided, and the health status of the batteries is improved. According to the hybrid control method, during the standing of the batteries, the equalizing current required for each battery cell is obtained by calculating SOC, so that an equalizing system is controlled; when the batteries work, each equalizing circuit is controlled by calculating SOC change rate, so that a potential unequalizing tendency is forecasted in advance and is corrected, and real-time equalizing for each battery is guaranteed. Moreover, according to the layered architecture and the control method, the rated current required for the equalizing circuit can be reduced, so that the system cost is reduced, and the energy loss is reduced.

Method for preparing natural sunscreen and skin whitening components in cosmetics by utilizing fruits

The invention discloses a method for preparing natural sunscreen and skin whitening components in cosmetics by utilizing fruits. Fruits sold on the market are cleaned twice with tap water; after the fruits are diced and weighed, carbohydrate which accounts for 5-30% the weight of the fruits and water which accounts for 1-3 times the weight of the fruits are added to completely dissolve sugar; the solid-liquid mixture is placed in a sterile fermentation tank and is subjected to controlled temperature fermentation for 90 days at room temperature of 20-39 DEG C; unsealing is performed after a fermentation period is due, and fermentation stock solutions are filtered and extracted in a sterile chamber. After the fermentation stock solutions undergo sterility detection, the fermentation stock solutions of different fruits are used independently or mixed proportionally, and natural perfume is added; and after the sterile test of the fermentation stock solutions is passed, filling is performed to obtain sunscreen components of the cosmetics. The sunscreen components are prepared by natural fermentation of fruit plants, and the sunscreen components have no artificial color and chemical functional components and have no adverse irritation to the skin.

Urban traffic health indicator system evaluation method based on complex network theory

The invention provides an urban traffic health indicator system evaluation method based on the complex network theory. The method mainly comprises the following steps: A: establishing a reliability indicator R of an urban traffic network; B: establishing a brittleness indicator B of the urban traffic network; C: establishing an elasticity indicator S of the urban traffic network; based on obtainedactual urban traffic operation data, importing seepage analysis to calculate the size of a functional sub-group of the urban traffic network under a given threshold, and establishing the reliabilityindicator R of the urban traffic network; mining a key road in the urban traffic network, analyzing a road set collapsing the functional sub-group of the urban traffic network to a certain proportion,and establishing the brittleness indicator B of the urban traffic network; and finally, establishing the elasticity indicator S of the urban traffic network through a whole process of generation-evolution-dissipation. The establishment of the urban traffic health indicator system can provide a support for the assessment of the actual operation state of the urban traffic, the development of targeted traffic management measures, and the improvement of the urban traffic health.

Hatching egg incubation illumination regulating and controlling method and illumination regulating and controlling device, with side-direction light supply

The invention discloses a hatching egg incubation illumination regulating and controlling method and an illumination regulating and controlling device, with side-direction light supply. Egg supports loaded with hatching eggs are placed on each layer of turnable egg stands, LED lamps are mounted above one side or multiple sides of each layer of the turnable egg stands and parallel to the turnable egg stands, and the LED lamps can turn along with the turnable egg stands; or the LED lamps are horizontally, or vertically or obliquely mounted on one side or multiple sides outside three-dimensional egg stands, and the LED lamps do not turn along with the turnable egg stands. After light enters, the hatching eggs perform diffuse reflection on the light, so that the light tends towards uniformity; when the hatching eggs are incubated, the LED lamps are regularly switched on, the light transmits egg shells of the hatching eggs, embryos mutually influence through squirm, and concurrent work and rest rhythm and hormone level are formed, so that the health state of the embryos is increased, the growth of the embryos is promoted, the incubation time is shortened, and the incubation rate of the hatching eggs, and the development and the stress resistant capacity of internal organs of chicks are improved. The hatching egg incubation illumination regulating and controlling method and the illumination regulating and controlling device disclosed by the invention are used for regulating and controlling illumination in the process of incubating the hatching eggs, the design is simple, the structure is reasonable, and the use rate of light energy is greatly increased.
