The emergence of hydrogen battery, Acer Aspire 1430 battery the battery capacity has improved significantly, but the "memory effect" did not completely eliminate the shortcomings.
In recent years, lithium-ion batteries in notebook computers has been rapidly growing popularity, due to lithium-ion batteries have basically eliminates the "memory effect" problem, it is repeatedly used to restore the depth of battery charge and discharge performance of the method no longer applies. But why the lithium-ion battery capacity will be reduced or the problem? The root cause for this situation, Acer Aspire 2930G battery is used in notebook computers and Yuanzhuang Li-ion battery built-in battery management system caused.
Battery management: current notebook computers, almost all use a "battery management" and "charge and discharge control" two chip-level management system. The "battery management chip" placed in notebook computers, the chip registers in the memory of the computer used in lithium-ion battery capacity, Acer Aspire 2930Z 322G25Mn battery temperature, ID serial number, charge and discharge status, total charge and discharge times and other important information. The data in the course, the need to constantly refresh the actual situation. The battery built-in "charge and discharge control chip," the most important role is to monitor and control the battery charge and discharge process and to the entire record.
Charging: Lithium-ion battery the charging process, divided into "constant current fast charge" and "voltage current charge" in two stages. The so-called "constant current fast charge" refers to just start charging, the charging current and charging voltage fixed to follow the battery terminal voltage is gradually increased until it reaches the nominal voltage charging method. Acer Aspire 5230 Series battery When the battery voltage has reached the standard value, the control chip will be automatically transferred to the "voltage current charge" stage, when the charging voltage will no longer continue to rise, while the charge current to follow the battery capacity is rising gradually decreasing and eventually reach zero, Acer Aspire 5235 Series battery so all will complete the battery charging process.
