Charging Process of Lithium ion recgargeable batteries
The charging process of lithium-ion battery can be divided into four stages: trickle charging (low voltage precharge), constant current charging, constant voltage charging, and charging termination. The basic requirements of lithium battery chargers are a specific charging current and charging voltage to ensure a safe charging of the battery. Other charging aids are added to improve battery life and simplify the operation of the charger, including trickle charging of over-discharged batteries, battery voltage detection, input current limits, switching off the charger after charging, automatic start-up charging after partial discharge of the battery, etc. The charging method of lithium battery is to limit the constant flow, is controlled by the IC chip, the typical charging method is: first to detect the voltage of the battery to be recharged, if the voltage is less than 3V, to pre-charge...
