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...

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...

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...
