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...

Long-term storage methods for lithium batteries and storage requirements for lithium iron phosphate batteries

Apr , 20 2024

What impact will the lithium battery have after being put aside for a long time? When the lithium battery is idle, due to the nature of the battery itself, self-discharge, passivation of positive and negative electrode materials, electrolyte decomposition and other phenomena will occur. The instability of the negative SEI will lead to the rapid decline of the negative active substance, which is ea...

What is the impact of low temperature on lithium batteries and solutions

Apr , 20 2024

The use of lithium batteries in low battery temperature environments is limited. In addition to a severe drop in discharge capacity, lithium batteries cannot be charged when the battery temperature is low. When the battery is charged at low temperature, the lithium ion embedment on the battery graphite electrode and the lithium plating reaction exist simultaneously and compete with each other. Und...

The difference between energy storage converter and grid-connected inverter

Apr , 26 2024

Energy Storage Converter Energy storage converters (PCS), also known as "bi-directional energy storage inverters", are the core components of the two-way flow of electricity between the energy storage system and the grid, and are used to control the charging and discharging processes of the battery, and to perform the conversion of AC and DC currents. In the absence of grid, it can directly supply...

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 ...

How Low Frequency UPS Safeguards Critical Information

May , 11 2024

What is a Low Frequency UPS? A Low Frequency Online UPS is a sophisticated power protection device that utilizes double conversion technology to provide continuous and clean power to connected equipment. Unlike traditional Offline UPS, where the load is directly powered by the mains until a power failure occurs, it continuously powers the load through an inverter, ensuring a seamless transition be...

Lead-acid battery failure model

May , 11 2024

The most common failure modes are: - Softening or shedding of the active material. During discharge the lead oxide (PbO2) of the positive plate is transformed into lead sulfate (PbSO4), and back to lead oxide during charging. Frequent cycling will reduce cohesion of the positive plate material due to the higher volume of lead sulfate compared to lead oxide. Corrosion...
