Improving the service life of lead-acid batteries has a very practical meaning, through the analysis of the above-mentioned factors affecting the service life of lead-acid batteries, in order to improve the service life of lead-acid batteries, it is necessary to do the following:
1) Strictly control the quality of battery ordering. In the process of battery selection and procurement, it is necessary to fully understand the manufacturer's production process, production process and quality control methods, as well as technical characteristics, etc., and if necessary, the manufacturer can be required to conduct the initial capacity test to select the battery with small differences.
2) Reasonable selection of charging equipment. BecauseSwitching power suppliesWith real-time monitoring and intelligent management functions, the sealed battery can always operate in the best state, so it is necessary to choose high qualitySwitching power suppliesas a charging device. High frequencySwitching power suppliesThe system should adopt a modular design, when the module is faulty, it should be able to immediately exit the operation, without affecting the normal operation of other modules, and the standby module should be able to take the initiative to ensure that the battery is not over-discharged due to module failure.
3) Pay attention to the quality of the device. The quality of the device includes many aspects such as storage, device, and capacity experiment, so care should be taken not to bump in the process of transportation and storage.
4) Be sure to replenish the power before putting it into use. Generally, the factory date of the electric bicycle battery is long to the first time, and the sealed battery will inevitably lose a lot of capacity through long-term self-discharge, and it is difficult to rely on a simple floating charge to achieve its initial capacity. In addition, because of the difference in the size of the self-discharge of the single battery, the specific gravity and terminal voltage of the battery are unbalanced, and the single battery will be further expanded into a backward battery or even show a reverse polarity phenomenon if it is not recharged before it is put into use.
5) Improve the quality of protection.
The protection personnel should engage in protection operations under the premise of fully understanding the common sense of VRLA batteries and improve the quality of protection.
The ambient temperature has a great impact on the discharge capacity, life, self-discharge, internal resistance and other aspects of the batterySwitching power suppliesIt has a temperature compensation function, but its sensitivity and adjustment fluctuations are limited. Therefore, the battery room should be equipped with air conditioning equipment and the temperature should be controlled between 22 and 25. This not only extends the life of the battery, but also allows the battery to have an optimal capacity.
Once a month, you should check whether the operating parameters of the charging equipment are within the qualified range, and there is a disease. In any case, the floating charge voltage of the battery should not exceed the float charge given by the manufacturer.
Carefully protect, use the method of pulse charging to charge the "backward battery", and promote the activation and improvement of the battery.
The battery cell voltage and terminal voltage should be measured once a month. The terminal voltage is an important parameter that reflects the good working condition of the sealed battery.
In order to ensure that the battery has sufficient capacity, a capacity test (i.e., large charge and large discharge) should be carried out once a year to activate the activated substances in the battery, and the capacity of the battery.
Regularly check the appearance of the battery for abnormal deformation and heating.
When the battery needs to be replaced due to insufficient capacity of a single piece, it can only be replaced at one time, and the battery with insufficient performance indicators can not be replaced alone, otherwise it will affect the play of the whole group of batteries due to the imbalance of the internal resistance of the battery, and shorten the service life of the whole group of batteries.
Do not add or reduce the load of several single batteries in the battery pack alone, this will form an imbalance in the capacity of the single battery and an inconsistency in charging, and reduce the battery life.
In short, it is necessary to pay attention to the protection of lead-acid batteries, according to the different characteristics of lead-acid batteries, for the main elements that affect the service life of lead-acid batteries, and constantly improve the level of protection, to achieve the purpose of improving service life.
