The current three-stage battery charger charging method is often used (linear charging mode), ie pretreatment, constant current charging, constant voltage charging. If the battery voltage is below the undervoltage threshold, first enter the preprocessing stage (with a trickle charge mode to charge the battery), if the battery terminal voltage is above the undervoltage threshold, direct normal constant - constant voltage charging way.
Rechargeable lithium hanged constant sustained, this will result in charging the electrode potential rise, lithium-ion is not fully embedded in graphite electrodes, it is difficult to make the battery is fully charged. Using constant current - constant voltage charging mode the capacity of the battery than using a single constant current charging mode last 20% -30% higher.
Lithium battery charging current is too large or just continuing with constant voltage charging, the battery capacity fading faster.
Standard charging current is 0.2C5A, and fast charging current is greater than the standard charging current. Obviously, fast charging is sacrifice battery performance for the price.
Pulse charging is also divided into three phases, with the first two stages of linear charging, once the battery voltage reaches the charge limit voltage charger began to enter the third stage, ie pulse charging phase uses pulse charging the battery can weaken the pole of effect, increasing the maximum value of charging current to shorten the charging time of the battery.
