How to float the battery

  Floating charging operation of battery:

   The battery using floating charging should always be in a fully charged state. The ability of the factory (station) to stop power supply (A.h) and the output voltage level required for the maximum accident load must be met. When the rectifier is powered off and the board is prevented from aging, make sure to provide a DC load.

  He said: “Density batteries that use the floating charging method must be inspected and discharged every three months, and 50 to 60% of them are solar The battery is discharged. 'The stop voltage complies with the manufacturer's rules, and the battery is charged immediately after discharge. If the rectifier device fails during this period, causing the battery to be forced to discharge, it is no longer possible to verify the discharge.

   For floating and operating rechargeable batteries, the constant voltage method is usually recommended. If a constant current method is used, the voltage of a single battery should also be controlled. The upper and lower limits of the floating voltage of a single battery must meet the requirements of the manufacturer's application protection declaration or operating procedures. If it is really impossible to find a clarification book, then the floating voltage of a battery can be controlled between 2.15V and 2.18V.

   The floating charge voltage of the 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 a    density battery is an important indicator to realize the floating charge operation method. The main basis for selecting the floating voltage is that the floating charge current of 2:1 is sufficient to compensate the self-discharge loss of the density battery. (2) When the battery is suddenly discharged, floating charging can make up for the power loss in a short time.

  二.Complete the charge and discharge operation

   Regardless of the battery discharge rate, overdischarge, discharge capacity and stop are not allowed The voltage cannot be lower than the product specification. Batteries using this method should be balanced every 3 months.

  3. Spare battery

   The intention of the standby battery is to ensure that the battery pack For normal operation, the backup battery can be replaced at any time. 'The backup battery should be charged regularly (3 months or 6 months) so that the backup battery always has a higher capacity. The electrolyte density of the backup battery should be maintained at the value specified in the manufacturer's specifications. Contact: 18038382979
