18650 battery charging method
18650 battery charging method is a systematic
problem: capacity, currents and their relationship, charging method used,
selection of chargers, which will affect the 18650 applicability
of battery charging methods, let us select from the charger to start.
In accordance with the 18650 structural
characteristics of lithium-ion batteries and charging system of national
standards, should select less than power the smaller volume of 1/5 The
current charger ( For small-capacity 18650 battery
pack, we can select 0.5C charging current ) On the
market, 18650 battery capacity 1800~2600mAh Between
selected lithium battery charger should be in 350~500mAh between
the charger is the right choice, you can avoid high current damage to the
battery, is also up for grabs in the context of security makes the shortest
charging time, from this point of view, select charger is 18650 first
important battery charging method.
Selected on the charger, 18650 battery
charging method is divided into two steps: first, constant current and constant
voltage. The first step is to constant current charging voltage up to 4.2V near,
the second step is to set values into constant voltage charging voltages up to
charger, constant voltage charging, voltage is not changed, the current
decreases, current decreases to 0.02C stop charging.
Without protection panels 18650 the
battery, you need to improve 18650 battery charging method in order to form a
long-term mechanism for improving battery performance, specifically: for new or
long-term shelving 18650 two or three times the depth of the lithium
ion battery charging and
discharging, which helps cells in the cathode to form a protective film to
prevent battery "passivization", and for battery protection board,
you do not need.
Because lithium-ion batteries have no memory effect, in
theory, can be recharged at any time feel free to discharge, but is plenty of
power for a long time without charging or battery always effective. 18650 battery charging method is one of the most
important and therefore are not battery just to 20~30% when
they rush to charge, which is equivalent to a full four or five shallow
discharge, tests showed that shallow discharge the end result is: the frequent
discharge of 18650 battery charging method could offer would be
less than the total electricity volume normal (power 85%~90%) discharge 18650 battery
charging method can provide total electricity, an average of nearly 1/4, method of judging the normal fill time is
also very simple, as long as 18650 battery charge reaches that point, using equipment will
send a signal.
By 18650 introduction of charging methods, we know 18650 battery
charger selection criteria, see 18650 battery charging are constant current and
constant voltage mode, and how to select the charging time in accordance with
the 18650 battery charging method, I believe your
battery power lasts, destruction will never come.
