Label: How to select the battery type according to the constant power discharge meter The constant power discharge of the battery is the time value from the beginning of the battery discharge, the discharge power does not change, until its terminal voltage drops to the critical voltage. We can select the battery based on this value. Let’s take a look at the constant power discharge characteristic table of the battery: we all calculate with a termination voltage of 1.80V/single cell. For example, the total load power is 1400W, and the actual configuration time of the UPS is 1 hour with 6 12V batteries and full load. In this case, the calculation method is as follows: 6 batteries * 6 cells per battery u003d 36 cells 1400/36u003d38.89 Looking at the above table, we get 12V38AH, and the discharge per cell per hour is 40.9W, so we can choose 6 cells The 38AH battery is used as a backup battery.
