The dataset contains high bandwidth voltage and current measurements of the main inverter of an electric vehicle. They were acquired from a Mercedes-Benz E-Vito on a testing ground in many different Operation Points (OP) listed in the following table:

Instructions: 

The dataset consists of 14 hdf5 files containing the measured data. In addition, there are two python examples on how to handle the data and plot same results, and one readme file.
The hdf5 dataset can be accessed with many different tools like matlab, octave or python. If you want to use the python example, you must place the python-file and the dataset in the same folder. A recent version of python (it was tested with Python 3.9.2) with the following packages is needed: h5py; matplotlib; numpy; random; os; sys and scipy.

Python demo:
There are two python example demos to read and plot the hdf5 datasets included:
The first one reads a single operation point and plots the data in the time and frequency domain. (import_hdf5_plot_single_demo.py)
The second one reads one dataset and calculates the short time Fourier transformation of all operations points in the dataset and plots a spectrogram. (import_hdf5_plot_dataset_demo.py)
The demo is made as an example on how to handle the data and can be used for further analysis.
The datasets can also be accessed via matlab/octave, but therefore I refer to the online support.
If you have any further question about the dataset, please contact the author.

 The dataset consists of results of 10 different tests conducted on 8 different types of battery cells. All batteries are designed in 18650, but they differ in manufacturer and composition. The measurements can be divided into three groups: constant load tests, WLTP tests at different temperatures and transient tests. Constant load tests are performed at 0.1C and 1C as a function of battery capacity, both during charging and discharging. During transient tests, a 360s load/charge is followed by a 60s relaxation.

Instructions: 

Please see the attached: Complex_battery_test_18650.docx.

This paper describes the design and practical application of a dual-stage H-Bridge (DSHBR) circuit to reduce the rectification losses and to minimise ripples in piezoelectric energy harvesting. The proposed DSHBR circuit integrates both AC-DC and DC-DC conversion processes using bidirectional switches and a step-up DC-DC converter, which applies to both positive and negative half cycles. One additional feature is that it does not require external power to turn on the bidirectional switches (Vth < 0.3 V).

The data provided here correspond to the TPWRS paper presenting a novel  filter design procedure to optimally split the Frequency Regulation (FR) signal between conventional and fast regulating Energy Storage System (ESS) assets, considering typical Communication Delays (CDs).  The filter is then integrated into a previously validated FR model of the Ontario Power System (OPS) including Battery and Flywheel ESSs, which is used to analyze the impact of these ESSs, CDs, and limited regulation capacity in the FR process in a real system.  The proposed methodology to split the

This dataset contains (1) the Simulink model of a three-phase photovoltaic power system with passive anti-islanding protections like over/under current (OUC), over/under voltage (OUV), over/under frequency (OUF), rate of change of frequency (ROCOF), and dc-link voltage and (2) the results in the voltage source converter and the point of common coupling of the photovoltaic system during islanding operation mode and detection times of analyzed anti-islanding methods.

Instructions: 

The anti-islanding protection relays are included in the "Relay Protection Bus B20 (20 kV)" subsystem.

This dataset was curated for outage management in electricity networks. It is based on a modification of the IEEE 24 bus reliability test system network. The modified network comprises 10 generators, 50 buses, and 40 load zones; supplying 270,000 customers. For illustrative purposes, the network is assumed to span the region between longitudes 13.2989°W and 12.9133°W and latitudes 8.1712°N and 8.4998°N. This region happens to be located in Western Sierra Leone and covers an area of approximately 681 square kilometres.

The dataset comprises:
