Self-discharge measurement of lithium batteries: resting and dynamic measurement methods

Jun , 14 2023

The measurement methods of self-discharge of lithium-ion batteries are mainly divided into two categories: 1) static measurement method, which obtains the self-discharge rate by standing the battery for a long time; 2) Dynamic measurement method to realize the parameter identification of the battery in the dynamic process. Static measurement method At present, the mainstream self-discharge measure...

Why choose gel batteries?

Aug , 22 2023

The colloidal lead-acid battery is an improvement of the ordinary lead-acid battery with liquid electrolyte. The sulfuric acid electrolyte is replaced by a colloidal electrolyte, and the safety, power storage, discharge performance, and service life are improved compared with the ordinary battery. The colloidal lead-acid battery adopts a gel-like electrolyte; no free liquid is inside. Under the sa...

Working principle of lead-acid battery

Dec , 23 2023

1. The generation of electromotive force of lead-acid batteries After the lead-acid battery is charged, the positive plate lead dioxide (PbO2), under the action of water molecules in the sulfuric acid solution, a small amount of lead dioxide and water produce dissociable unstable substances - lead hydroxide (Pb (OH) 4), hydroxide ions in the solution, lead ions (Pb4) remain on the positive plate, ...

What is the meaning of float charging for intelligent three‐stage charger in battery charger?

Jul , 12 2024

Float charging: Keep constant voltage charging, the charging current continues to decrease, and the battery is charged with maintenance type. When the charging current decreases to the set value or the charging time reaches the set value, the red light of sufficiency will be on, and the time will be about 2H, charging 10% of the power. Ordinary chargers are old‐fashioned chargers, charging, whethe...

Effect of electrolyte density and discharge on lead-acid batteries

Nov , 29 2024

(1) Electrolyte density under different geographical and climatic strips. Whether the electrolyte density is high or low, it is necessary to make a specific analysis for the specific situation. Winter temperature is low, the viscosity of the electrolyte is large, it is not easy to penetrate the inside of the plate, the end voltage and capacity of the battery will decline, especially in the strong ...
