    Lithium-ion battery terms explained

    Aug , 18 2023
    I. Battery voltage (V) 1. Open circuit voltage (OCV) The voltage of the lithium battery when it is not connected to an external circuit or load can generally be tested with a multimeter. 2. Operating voltage (WV) The potential difference between the positive and negative terminals of the battery under applied load, that is, when there is current flowing through the battery in the circuit. When the...

  • Why choose gel batteries?

    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...

  • Lead-acid battery thermal runaway failure analysis when the battery is in the state of charge

    Lead-acid battery thermal runaway failure analysis when the battery is in the state of charge

    Sep , 04 2023
    Lead acid battery thermal runaway fault analysis When the battery is charged: There is a cumulative increase in battery temperature. When the heat accumulates to a certain extent during the warming process, the battery terminal voltage will suddenly decrease, forcing the current to increase suddenly, and the phenomenon of high battery temperature and damage to the battery is called thermal runaway...

  • Effect of temperature on the performance of lead-acid batteries

    Effect of temperature on the performance of lead-acid batteries

    Sep , 18 2023
    What are the effects of temperature on the performance of lead-acid batteries? From the chemical reaction equation of lead-acid batteries, PbO2 is on the positive plate, and Pb is on the negative plate. The electrical and physical properties of these two substances vary very little with temperature, so it can be said that the temperature effect of the discharge performance of lead-acid batteries i...
