What is pulse charging and output power of a battery?

Oct , 24 2022

What is pulse charging? What is the impact on battery performance? Pulse charging generally adopts the method of charging and discharging, that is, charging for 5 seconds and discharging for 1 second, so that most of the oxygen generated during the charging process will be reduced to electrolyte under the discharge pulse. It not only limits the vaporization of the internal electrolyte, but also fo...

Comparison of N-type and P-type cells for photovoltaic modules

Aug , 18 2023

Photovoltaic cells are classified by substrate material and can be divided into P- and N-type batteries. A P-type battery refers to a battery with a P-type silicon wafer as the substrate, and an N-type battery refers to a battery with an N-type silicon wafer as the substrate. P-type silicon wafers have a simple production process and low cost, while N-type silicon wafers usually have a long life a...
