Maintenance of car battery
For example, the battery used in the car (commonly known as the battery) is a 12V battery pack with 6 lead-acid batteries connected in series. The relationship between the voltage of the car’s 12V lead-acid battery and the remaining power is shown below Table 0% Internal Resistance and Capacity The relationship between battery internal resistance and capacity, which has two meanings, the relationship between battery internal resistance and rated capacity. And the relationship between the internal resistance of the same type of battery and the state of charge. More than ten years ago, people tried to use the change of internal resistance (or conductance) of VRLA batteries to detect battery capacity and battery life online. But it failed; people have put forward higher and higher requirements for the high-current discharge capability of power batteries. This requires reducing the internal resistance of the battery as much as possible, so this article will further and clarify the internal relationship between the internal resistance and capacity of some commonly used batteries. Valve-regulated and sealed lead-acid batteries with valve-regulated and sealed lead-acid batteries have gradually taken the lead-acid batteries with flowing electrolyte.
So after discharging, be sure to charge it immediately. If the discharge state is left alone, the lead sulfate will form stable white crystals (this is the vulcanization phenomenon described in the literature). Even if it is charged, there is no active material on the plates. When the white lead sulfate battery is discharged, lead sulfate (PbS04) is produced at the anode and cathode plates at the same time, if they are allowed to discharge. Does not charge. Then it will form stable white lead sulfate crystals (even if it is recharged, it is difficult to restore the original active material). This state is called white vulcanization. The temperature during discharge is when the battery is discharged. The internal impedance is significant, so the battery temperature also rises. Theoretical capacity Theoretical capacity is also known as the calculated capacity is determined by the amount of active material contained in the battery plate. The electrochemical equivalent of lead-acid batteries is ·h/g for Pb, and ·h/g for 2 and ·h/g for Pb02. How much is the battery price in Dongguan?
If the pointer rotates clockwise, the pole touched by the red pen is positive, if the pointer rotates counterclockwise, the pole touched by the red pen is negative. How to measure the battery level To use the watt-hour meter method to measure the battery power, use an electro-hydraulic hydrometer to check the size of the electro-hydraulic specific gravity to detect that the battery power has occurred. How much is the battery price in Dongguan?
When using , you should open the plug of the single battery and place the hydrometer in the electric hydraulic cylinder to measure the specific gravity of the electric hydraulic cylinder. When the power is sufficient, the specific gravity of the electro-hydraulic should be. If the specific gravity of the electro-hydraulic is, the discharge capacity of the battery has reached 50%. At this time, the battery should be charged before use.
