How many kilowatt hours does it take to fully charge a 175 Ah lithium iron phosphate battery?

The voltage of a single lithium iron phosphate battery is 3.2 V. If a 100 Ah 12 V lithium iron phosphate battery is fully charged, the power consumption can be approximately calculated as follows: 3.2 (voltage) x 4 (number of batteries). batteries) x 100 (Capacity) = 1280 (kilowatt hours), or 1.28 kilowatt hours of electricity. This is a rough estimation method, because the battery voltage will continue to increase during the charging process, and considering the charging efficiency, the actual charging consumption will be slightly higher.
