Lithium-ion batteries - Knowledge about charging

1. Really is the bigger the charging current, charging the faster? For constant current charging nickel-based batteries, so to speak, and corresponding lithium ion battery, this is not entirely correct. Painted painted for lithium ion battery charging, within a certain range of current ( 1. 5 c ~ 0。 5度) Way, enhances the constant current constant voltage charging the constant flow of current value, and can't shorten the time of the charge lithium ion battery. 2. Fill continuously target output current is equal to the charging current? This will discuss phone charging ways, charging for management in mobile phones, set a straight charger (same Should really be called power adapter) The output of such as: 5. 3V 600mAA. Charging management is switch mode ( High frequency pulse width adjust PWM mode) , the charging mode, mobile phone has not completely using the output ability of imitation, fill continuously work at constant pressure, the output of 5. 3 v, the real charging current adjustments by the mobile phone charge management, and must be less than 600 ma, ma is in commonly 300 ~ 400. This time, we see straight filling the output current is not charging current of the phone. Many of such as MOTOROLA straight filling the output is 5. 0 v 1 a, really for the battery is used in the 500 ma is enough, because the cell phone battery capacity is 580 mah. U then fill continuously the output current is not equal to the actual charging current marked on B. For pulse charging management way, the way of charging, the phone completely through the direct current limiting current, is to use the 600 ma on the battery, this time, the direct filling of the output current is the charging current. Of course the above refers to the constant current phase in the lithium ion battery or nickel metal hydride battery charging. If the phone without charging management, moved to the running of the charge to fill continuously, such as many of the CDMA mobile phone, this have nothing to say, its output to write clear, such as output: 4. 2 v500ma, this is the lithium ion battery constant current constant voltage two data. Lithium-ion batteries, electric vehicles, lithium battery manufacturer, storage battery manufacturer scooter battery manufacturers, product by the supervision and inspection institute of guangdong province, through international CE certification, by the ping an insurance company of China national group, two years warranty, the first in the New Year.
