Introduction
Battery backup power to emergency supply system failure is a major risk to security, how to prevent a sudden failure of the battery is a maintenance technology of the battery in a challenge. At the moment, the battery showed an unexpected failure in the unpredictable nature of battery failure warning technology to study the driving force. Hp laptop battery The key to reaching the battery fault warning is to find the best parameters of early warning, of course, the parameters of early warning should be better to have three characteristics, namely the lack of high correlation of the battery may be repeated measure nature of comparability.
Battery aging theory is to guide the design of the battery and manufacture and improve the theoretical basis, but the theory of aging primarily for the integrity of the battery, but a battery failure is the main difference on the battery The battery aging theory does not apply to batteries sudden failure analysis of hair, it does great performance in a variety of battery failure on the idea of early warning program. A variety of practical engineering of existing programs, both program voltage single voltage or current loop + alone program or programs or fast program high intensity discharge test capabilities, are all parameters Implicit in battery capacity as a warning, but in fact, neither have the battery capacity of direct, HP Presario M2000 Battery(compaq m2000 battery), HP Presario V2000 Battery(compaq v2000 battery), HP pavillion zx5000 Battery(HP hp zx5000 battery), repeated measurements (for example, to test the ability of periodic discharge), or with repeated measurement of indirect (by for example, by measuring the voltage or the computing capacity of resistance). Theory of aging of the battery to the battery warning ideas on the chains of the urgent need to review the battery from a perspective of new security measures in order to find the best early warning parameters established theoretical basis is the theory of cell damage must be resolved.
A mechanism of cell damage
1.1 The definition of battery damage
Interpretation of "over-charging or battery discharge harmful," the caution common to others: over charge or discharge current will cause the reaction energy storage outside the irreversible electrochemical reaction, this conception is linked outside the irreversible damage response capacity storage battery power structures existing. (HP hp zx5000 battery), This can damage the batteries as follows: "a battery against overload and lower structure and storage capacity can be caused by damage to natural regeneration. "
Superficially, this definition of aging theories and battery and battery application of common sense is not significantly different, however, the definition would lead naturally to two questions really significant:
A) a practice of art in the current standard to avoid damaging the battery, it?
2) damage to the battery, the battery has left, what kind of reproducible measurements can be compared to each other physical changes?
1.2 "Sound of the current system standard" defined
Battery failure can come from human error, equipment failure can come of these reasons are not cell injuries learning theory, the theory of cell damage is more concerned about the inevitability of failure battery itself.
As to exclude all factors other than interest, first necessary to define a "good of the current standard system." (compaq v2000 battery), A good system of existing standards should include at least: one of the technical indicators are fully qualified food real, a point of order by the only qualified in accordance with the battery connected real well with qualified management and the maintenance staff in the implementation of a rigorous maintenance procedures, in a word that should be faultless, but in reality it is a standard system.
