52 results about "Battery (electricity)" patented technology

A battery is a device consisting of one or more electrochemical cells with external connections provided to power electrical devices such as flashlights, mobile phones, and electric cars. When a battery is supplying electric power, its positive terminal is the cathode and its negative terminal is the anode. The terminal marked negative is the source of electrons that will flow through an external electric circuit to the positive terminal. When a battery is connected to an external electric load, a redox reaction converts high-energy reactants to lower-energy products, and the free-energy difference is delivered to the external circuit as electrical energy. Historically the term "battery" specifically referred to a device composed of multiple cells, however the usage has evolved to include devices composed of a single cell.

A battery swap station operation data reconstruction method based on adaptive truncation and feature correlation repair

PendingCN122332727AData streamEngineering
This invention discloses a method for reconstructing battery swapping station operation data based on adaptive truncation and feature correlation repair, belonging to the field of data reconstruction technology. First, a standardized two-dimensional spatiotemporal discrete model is constructed, and sequence mapping technology is used to align the discrete data stream to the date-time period operation space. Second, a zero-first truncation model based on the continuity of frequency distribution is established to adaptively remove outliers and noise. Then, Latin hypercube sampling and inverse cumulative distribution function transformation algorithms are introduced to fill in missing values ​​while ensuring that the reconstructed data conforms to the original probabilistic characteristics. Finally, the battery swapping frequency-electricity data is dimensionally reconstructed to facilitate the inductive analysis of battery swapping behavior characteristics. Numerical examples demonstrate that the method proposed in this invention effectively restores the statistical usability of the data, fully revealing the bi-peak tidal characteristics of battery swapping load and the distribution law of low-electricity anxiety, providing relatively reliable data support for load forecasting and regulation.

The mini-standalone photovoltaic power station comprises solar panels, an inverter, a step-up transformer, a battery, a magnetic amplifier, a microcontroller, and a rheostat. Solar panels generate DC electricity, which is converted by an inverter to AC and fed to a step-up transformer to power autonomous loads. A separate solar panel powers the magnetic amplifier and charges the battery. A microcontroller controls the magnetic amplifier, regulating the saturation of its magnetic wire depending on the input voltage, battery status, and load. A variable rheostat allows the gain of the magnetic amplifier to be adjusted depending on the current operating mode of the system. Using a magnetic power amplifier powered by a separate solar energy source allows the regulator to operate independently of the main circuit, increasing efficiency, reducing conversion losses, and ensuring output voltage stability under changing solar radiation and load conditions. The technical result consists in increasing the energy efficiency, reliability and stability of the operation of an autonomous photovoltaic station due to the introduction of a magnetic power amplifier with autonomous power supply and microprocessor control.
