Lithium battery cycle data analysis with constant voltage charging current and capacity decay curve
Oct , 29 2021
Generally, cycle life testing will generate a lot of data, which can obtain a lot of information. What analysis and processing can we do with these cycle data? The following summarizes some of the data processing, continuation from last week’s article. 1. Constant voltage charging current and time Lithium-ion batteries are usually discharged at different currents during use, and often cannot under...

What is the difference between three-phase current and phase current
Mar , 01 2024
The relationship between line current and phase current is as follows For a star connected motor, the phase current is equal to the line current. For motors with triangular connections, the line current is equal to √ 3 times the phase current, and the line current lags behind the phase current by 30 °. Phase current refers to the current flowing through each phase load in a three-phase power suppl...

Harmonic current
Apr , 20 2024
What does harmonic current mean Harmonic current is a collective term for the sinusoidal components whose frequency is an integer multiple of the original periodic current frequency. A harmonic current with a frequency equal to k times the frequency of the original periodic current is called a k-th harmonic current, and all harmonic currents with a frequency greater than 1 are collectively referre...

Measures to suppress harmonics
May , 11 2024
The fundamental cause of harmonic generation is due to nonlinear loads. When the current flows through the load and does not have a linear relationship with the applied voltage, it forms a non sinusoidal current, resulting in harmonics. The suppression of harmonics in the power system is to reduce or eliminate the harmonic current injected into the system, in order to control the harmonic voltage ...

What are Harmonics
Aug , 17 2024
1. Definition of harmonics In the AC power grid, due to the operation of many nonlinear electrical equipment, the voltage and current waveforms are actually not complete sine waveforms, but non-sine waves with different degrees of distortion. Harmonic refers to the amount of electricity contained in the current whose frequency is an integer multiple of the fundamental wave, and generally refers to...
