    Effect of ambient temperature on battery life

    Mar , 01 2023
    1)Temperature will affect battery capacity At different temperatures, the viscosity of the sulfuric acid solution in the battery will be inconsistent. For example, when the battery is at a temperature below 0°C, as the temperature decreases, the resistance of the sulfuric acid solution will continue to increase, which will directly increase the weight of the electrode. The effect of polarization, ...

  • Three-stage charging of lead-acid battery

    Three-stage charging of lead-acid battery

    Apr , 15 2023
    1. What is the three-stage charging of lead-acid batteries? The charging method of lead-acid batteries should be divided into three stages, namely: constant current charging - constant voltage charging - trickle charging. Constant current charging stage: charge to 13.4V with 0.2C10 A current. Constant voltage charging stage: 2.4V/cell, charging time 3h, cut-off current 0.02C10A Trickle charge phas...

    The Role of AC Capacitors in High Speed Circuits

    Aug , 18 2023
    1、Introduction For low-frequency circuits, resistors and capacitors can be analyzed as ideal devices. However, in high-frequency circuits, these two devices will not be "ideal". Today, our main discussion is about the issue of AC capacitors, which are commonly known as AC coupling capacitors. Their main function is to filter out the DC component of the signal, which is symmetrical about the X-axis...
