Series and parallel connection of capacitors

Feb , 23 2024

Capacitor series connection: The total capacity decreases, but the withstand voltage value increases. The withstand voltage value is the sum of the withstand voltage values of two capacitors. Capacitor parallel connection: The total capacity increases, and the voltage withstand value is taken as the voltage withstand value of the smallest capacitor. If two capacitors are exactly the same, the volt...

Choose the Smart UPS between Online UPS vs Line Interactive UPS

Mar , 14 2024

Online UPS vs Line Interactive UPS While both UPS provide full protection from major power problems, such as surges, spikes, sags, blackouts and brownouts, they differ in a few significant areas. Simply put, an on-line UPS offers a higher level of protection than a line interactive at a higher cost. More specific areas where the two types differ include sine wave output, voltage regulation, and do...

Why is lithium battery suitable for UPS battery?

Mar , 22 2024

1. High energy density: Lithium batteries have high energy density, that is, batteries can store more energy per unit mass. This means that the relatively small size and weight of lithium batteries can store more power. For UPS applications, this is important because it means that lithium batteries can provide longer backup times. 2. Long cycle life: The life of lithium batteries is usually longer...

Effect of low temperature on battery performance

Mar , 30 2024

When the lithium-ion battery is in a low temperature state, its available capacity is reduced and the charge and discharge power is limited. If the power is not limited, it will cause the evolution of lithium ions inside the battery, which will lead to irreversible attenuation of the battery capacity, and will bury a safety hazard for the use of the battery. The lower the ambient temperature, the ...

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...
