What do you need to pay attention to when replacing lead acid with lithium in UPS applications?

Mar , 22 2024

Understand battery characteristics: Before you start switching, be sure to understand the characteristics and operating requirements of lithium batteries. Compared with lead-acid batteries, lithium batteries have a higher energy density and faster charging speed. However, they are also more sensitive and require special charge and discharge management. Select the right lithium battery: Select the ...

Advantages of Solar Gel batteries

Apr , 02 2024

Are Gel Batteries Better For Solar? The modern gel battery was invented in 1957. Gel batteries are one of two sealed lead acid batteries, the other being an AGM battery. Sealed lead acid batteries are distinct from other lead acid batteries in that they are maintenance-free What’s in a gel battery? A gel battery is a dry battery since it doesn’t use a liquid electrolyte. In a gel battery, the elec...

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...

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 ...

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...
