About the battery charge acceptance
1 Introduction
Acceptance of battery charging for Dell Inspiron B120 battery performance is a significant indicator of battery charge on behalf of its intuitive performance standards high and low, but the introduction of the internal battery and traction batteries last bike power, which do not charge acceptance capacity requirements can be found in practice for the VRLA battery to charge voltage limiting mode, and traction system, working environment deep cycle, the level of charge acceptance for the battery capacity and cycle life, a film more important as.
Battery charge acceptance ability to limit testing in different conditions, ranging from its mean it is. Under specified conditions, such as processing 1Ah active substance, how much current is transformed Ah, that is to say that although the capacity of the battery charge acceptance, but rather should be “under provisions in charging acceptance “most people are used to load acceptance capacity specified in the provisions of the environment, the value of a constant amount of time to detect the load value of loop current that the size of the charge acceptance, of course, is also a charge acceptance of representation but in the VRLA hp F4486B battery charging system, the ability to accept more good presentation.
Because the battery to a different depth of discharge, charge temperature, current limit depressed pricing to accept different in some laboratory tests very good battery, but unable to stand the test of the relevant market loader is to load because different settings, leading to huge differences in the dissemination of results. The final product is to penetrate the market, the batteries occupy the market to survive, they must learn to adapt to the living environment in this market. Therefore, the burden of acceptance testing is simulated in any market for electric bicycle charger control, indicated both in the absence of special agreement refers to “the battery at 100% depth of discharge 14.8V constant voltage, current limit is not more than 0.2 C, termination conditions are charging circuit current less than 0.03C, which were filled with the output ratio of the total electricity consumption of total capacity, the capacity charge acceptance. ”
2 The acceptance and the capacity of the life cycle of the association
Under the agreed acceptance load test methods to detect than the sony VGP-BPS2 battery of different formulations and participate in several electric vehicle manufacturers data life cycle of the battery test, the load capacity and acceptance cycle Life has shown the tendency of the three basic types.
With the ability to accept charge, battery capacity and cycle life were increased, indicating acceptance of the VLA capacity of the battery cycle life were directly related to the corresponding.
3 Acceptance support lifecycle factors influencing
Acceptance of burden and trends of the life cycle of accepting charge of the three categories in terms of volume measured immediately after the expiration of batteries for the qualitative detection and found that three types of failure have a certain pattern .
apple M8403 battery capacity class after the break, the loss of water from the battery positive plate less intact, no obvious grid corrosion, negative sulfate serious, apparently because of poor charge acceptance, resulting cell cycle have failed each time sufficient electricity, lead sulfate has continued to increase, leading to the cathode sulfate severe pressure drop in the polarization of the cathode, so that the battery charge and discharge are not normal, the failure of the battery.
classes battery capacity after the failure, loss of water from the battery is high, positive plate intact, plaque remove some corrosion sulfate significantly negative, the situation is the gradual accumulation of sulfate negative, so the battery negative terminal of the polarization ability to continue to decline, causing the battery to water loss increases gradually, many times in the 6.0 cycle, the capacity is failing.
Class battery capacity and cycle testing of more than 200 Re-cycle all have better performance, loss of water from the Dell Inspiron 6400 battery by about 7%, slightly to the corrosion of plates, negative no obvious signs of sulfation.
Tired of the other three cycles and the results of qualitative tests look, capacity VRLA battery charge acceptance and life cycle right there is a direct actor, poor charge acceptance of lead-acid batteries can not completely charged, the negative electrode plate in dozens of cycles would seriously sulfate battery failure between the imposition of a lack of absorptive capacity to charge batteries in the tens of cycles, we started electricity may not be quite enough, so that the negative plate sulfation build slowly corrosion of the battery positive and negative polarization of water loss has continued to increase at a certain cycles on the battery performance is clearly inadequate, and bands by nature deteriorates rapidly as the official home of a good battery in detecting more than 200 cycles in the overall performance of the battery are good, are dehydration negative plaque status better rarely, and the performance of cells maintained in good condition, no downward trend in major.
Overall, can influence the acceptance of responsibility corrosion cells positive, negative sulfate, water loss of battery charge efficiency and whether or not the power quite properly, the capacity fade sooner or later, and the rate of occurrence of a turning point, and so on, thus affecting the battery capacity and cycle life.
