Role and application of multilayer graphene in lead-acid batteries

Jan , 26 2024

Early capacity loss of lead-acid batteries (PCL-3) - irreversible sulfation of the negative electrode The research shows that: At different discharge rates, the distribution of PbSO4 generated by the negative electrode is different. At low discharge rates (< 0.5C20), PbSO4 crystals are uniformly distributed inside the plate, and the crystal particles are relatively coarse, while at high dischar...

Why do PCS need to match the lithium battery BMS protocol?

Feb , 03 2024

First, what is the main role of the BMS protocol? In simple terms, the BMS protocol is a set of rules and standards for coordinating and managing interactions between various components inside a lithium battery. It can ensure the safe use of the battery and prevent the occurrence of dangerous situations such as overcharge, overdischarge and overheating. At the same time, the BMS protocol can also ...

Zero line electrification poses the following hazards

Feb , 03 2024

(1) When the zero line is disconnected, due to load asymmetry, the neutral point drift is caused, and the voltage of one phase of the light load will increase. When it exceeds the rated voltage of the electrical equipment, it will shorten the service life of the equipment. If it exceeds the rated voltage too much, it may even damage the equipment and cause a "group explosion" of household applianc...

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...

The relationship between temperature and battery

Mar , 22 2024

High ambient temperature greatly affects the battery service life. When the temperature rises, the corrosion of the battery plate will increase, and more water will be consumed, thus shortening the battery life. The battery can obtain a long life at 25 ° C, and the service life is reduced by about half if the long-term operating temperature is increased by 10 ° C. The storage battery should be pla...
