battery charging

"Battery is not bad but the charge with the bad", this is simply not an alarmist, battery charger on the battery life good or bad performance, and the use of performance play a decisive role, we must attach importance to.

1, battery charging process on the requirements of IBM ThinkPad T41 Battery

Understanding of battery charging process on the basic requirement is to analyze the basis for charging technology. Dell Latitude C600 Battery, Battery on the charge of the basic requirements are: the charge current should be less than or equal to the battery charge current can receive. Otherwise, the excess of current liquid too quickly cause electrolysis of water consumed to produce the following hazards: increased battery water loss rate, increase the maintenance workload for the maintenance-free batteries,Dell Latitude C600 Battery, Dell Latitude C610 Battery, Dell Latitude C640 Battery, Dell 1691P Battery, can cause early battery failure; produce mist, resulting in environmental pollution, health hazards to workers health; to reduce the charging efficiency, resulting in a serious waste of energy.
Charging process is the reverse electrochemical reaction discharge reaction process, if the rechargeable electrochemical reaction process carried out in an ideal state, this process should be mutually reverse reaction, that is filled into the electricity and the release of electricity should be almost equal. However, in a serious analysis of gas state, the effective charging energy consumed in the electrochemical reaction process not reach 40% of the total electricity consumption, that is a waste of electricity over 60%.

Gases within the porous electrode gathered in the batteries, reducing the electrolyte and porous electrode contact area, that is, charging the electrochemical reaction interface is drastically reduced, so that chemical reaction speed reduced charge, the charge is very difficult to extend the charging time.Gassing serious damage batteries: IBM ThinkPad R60 Battery  IBM ThinkPad T60 Battery
① a large number of gases to the electrode active materials are scouring effect, so that active substances that can loose and shedding.

② In the high polarization voltage, the positive plate grid will produce severe corrosion, generate Pb02, the corrosion and electrochemical survival Pb02 is completely different, which is not reversible oxide, conductive poor, enable grid deformation, embrittlement, loss of the role of skeleton and conductivity.Dell Latitude C610 Battery, Therefore, in the charge should be possible to prevent the overcharge.

Less than the long-term charge, no reaction of active substances leads to irreversible high-positive large particles PbS04 grain (ie, irreversible sulfate) to enable the battery capacity decline in resistance increase, charging more difficult, resulting in early damage to batteries. Therefore, as far as possible to ensure adequate battery power, to prevent irreversible sulfation.

2, charging the choice of frequency

Battery charge cycle life on the great influence on the depth of the basic exponential change. This is because the positive active material for Pb02, the combination of fastness is not high, discharge into PbS04, charging Shiyou into Pb02, andThe volume ratio of about 2:1. Therefore, positive plate, the active material expands and contracts will be repeated so that the connection between particles gradually fall off, so that loss of battery discharge characteristics of active materials as "anode mud" so that battery performance degradation until the end of life. The deeper depth of discharge,Dell Latitude C600 Battery, Dell Latitude C610 Battery, Dell Latitude C640 Battery, Dell 1691P Battery, expansion contraction the greater the damage to the active material binding the larger the shorter life expectancy; and vice versa the longer cycle life.

In theory, should try to avoid the use of deep battery discharge, should be placed shallow ground charge, provided there is a special match matching charger. But the actual use, due to battery charging performance and battery by the charger and charge their own habits and discrete charging speed of impact than those in the higher voltage charger, charging more or less existed. In particular, charge mostly in the night time is generally 6-10 hours, an average of 8 hours or so, if the shallow discharge, the charging will soon reach the end of charge efficiency changed when low, will have been charging. Over relatively long charging time, coupled with frequent charging, battery life would make a greater impact due to charge being.
Optimal charging request according to the actual circumstances, to refer to normal operating frequency, mileage situation, Dell Latitude C640 Battery, the instructions provided storage battery factory, as well as supporting the development charge charger performance parameters such as frequency. According to the vast majority of the user's situation, battery to discharge a depth of 50% -70% of the best to recharge a battery so that battery life can achieve the best results. When converted into the actual use of riding mileage on one charge when needed.

3, the impact of temperature on the charge

Battery is running in the hot season, the main problem existed charge. Dell Inspiron 9200 AC Adapter   Dell Inspiron 9300 AC Adapter Battery when the temperature increased, the activity of all active substances increase in oxygen evolution potential of a decline in positive and negative oxygen evolution potential is also reduced (negative down), so charging charging reaction speed, charge current, charge needed to charge voltage is low. In order to prevent excessive charge voltage, battery temperature should be reduced to ensure good heat dissipation, to prevent sun exposure after charging, and should be away from heat.

Battery at low temperatures, the various active substances to reduce the activity of its dissolution on the electrode becomes difficult, charging hard to be replenished after depletion, the charge current significantly decreased, when the positive plate at -20 ℃ charge acceptance of current is only at room temperature for 70%, while the negative effects of charging by the expansive agent, low-temperature charge acceptance of a lower, -20 ℃ to accept the charging current of only 40% at room temperature. Therefore, the main charge under the conditions of existence of low-temperature charge acceptance ability is poor, Normal 0 7.8 磅 0 2 false false false MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:普通表格; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin:0cm; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-fareast-font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;} Dell Inspiron 630m AC Adapter  Dell Inspiron 6400 AC Adapter  ,charging the problem of insufficient, calling for improvements to extend the charging voltage and charging time. To improve the low temperature performance of the main set should be negative. Antifreeze should be taken to use low-temperature thermal insulation measures, in particular charge should be placed in a warm environment,Dell 1691P Battery, conducive to ensure adequate electricity, to prevent the irreversible production of sulfuric acid to extend battery life.

During the storage and use of batteries can be activated periodically charging the so-called equalizing charge, which is irreversible sulfate to prevent the battery is very good for battery life is very good, worth advocating.
