Several methods of battery floating charge operation

   Battery floating charging operation:


   The battery using floating charging should always be in a fully charged state, and the actual capacity must meet the requirements of a complete shutdown of the plant (station), and should be abruptly The power supply capacity (Ah) and output voltage level required to accept the maximum accident load. 'To ensure that when the rectifier loses power, it needs to provide a DC load and prevent the board from aging.


   Perform nuclear discharge every 3 months, discharge 50%-60% of the battery, stop boosting to the manufacturer’s regulations, and charge the battery immediately after the discharge is over. Operate the battery according to the float charging method, and conduct a nuclear discharge every three months. If the battery is forcibly discharged due to the failure of the rectifier device during this period, the nuclear discharge can no longer be performed.


  The battery pack is usually operated by the constant voltage method. If the constant current method is selected, the voltage of the single cell should also be controlled. The upper and lower limits of the floating charge voltage of a single battery are necessary to comply with the manufacturer's application protection specifications or operating procedures. If the statement cannot be found, the floating charge voltage of a single battery can be controlled between 2.15V and 2.18V.


   The floating charging voltage of a battery is based on a certain ambient temperature (such as 20°C, 25°C, etc.). If the room temperature of the battery violates the reference temperature for a long time, the floating charge voltage should be adjusted according to the manufacturer's regulations.


   The floating charge voltage of the battery is one of the important indicators for implementing the floating charge operation method. The main basis for selecting the floating charge voltage is 2: The floating charge flow is sufficient to compensate for the self-discharge loss of the battery. When the battery is completely discharged, the floating charge can make up for the lost power in a short time.


  2. Full charge and discharge operation


   Regardless of the battery discharge rate, the discharge capacity and stop voltage cannot be lower than the product Rules in the specification. The battery using this method of operation is charged once every 3 months.


  3. Spare battery


   The intention of the spare battery is to replace the battery pack with a spare battery at any time to ensure The normal operation of the battery pack when the battery pack fails. 'The spare battery should be charged regularly (3 months or 6 months) so that the spare battery always has an ambitious capacity. The electrolyte density of the backup battery should be maintained at the normal value stated in the manufacturer's statement. Contact: 18038382979
