Lithium batteries need to control its charging voltage, limiting the charging current. Usually three-stage battery charging method, pre-charge, constant current and constant voltage electrical width. Lithium battery charging current should normally be limited to 1C (C for the lithium battery capacity) about the monomer charging voltage is typically 4.2V, otherwise it may be due to high electric Cong key will cause permanent damage to the battery. Pre-charge is mainly to complete the over-discharge of lithium battery for repair, if the battery voltage is below 3V, it must be pre-charged, not just the stage can be omitted. This is the most common situation. In the constant current stage, give the battery charger to provide a large constant current to the battery voltage rises when the soul to reach saturation voltage on the battery voltage, then transferred to regret pressure, charging voltage fluctuation should be controlled at less than 50mV, while the charge current reduces When the current is gradually reduced to the required value, to end the charging process. Most of the battery used to power flow and constant pressure in the stage from the charger into the battery. Song the foregoing, the charger is actually a precision power supply, the current and voltage are limited to the required range. |
