DC screen uses 12V250AHOPZS tubular battery capacity calculation method

DC screen uses 12V250AHOPZS tubular battery capacity calculation methodThe battery capacity problem is the problem that the user is very concerned. The business says that the capacity of a battery is reliable. Today, today's lithium battery manufacturers come with everyone to analyze the battery capacity test method, we can test the battery capacity:


Huizhong - Huizhong brand OPZV tube colloidal battery main components: Polar material 1 # Electrolysis lead, separator is an imported partition for the United States, colloid is German import colloid.
The self-discharge and polarity of the battery are gradually vulcanized by lead-acid batteries, but with the increasingly strict requirements of product materials and processes, such as lead-lead alloys are lead calcium alloys, and gradually become ' Free maintenance is maintenance. Some people are accustomed to using the voltage files that use the voltmeter or the multimeter to check whether the battery's storage is sufficient, which is unreliable. Since even the battery of the power is activated, as long as the discharge is stopped, the positive and negative electrode plate and the electrolyte of the battery can be immediately reached, and the potential difference between them can be restored, each monogram 2.1V, the entire battery is about 12.6V or more. When the voltage is measured on a single measurement, the current is extremely small, so it does not generate a large pressure drop in the inside of the battery, so the display voltage is not low, but if a considerable load, such as a headlight (10 ~ 15A), the speaker (6 ~ 12A), the battery will make the lights, the hoarse, thus showing insufficient storage.

When the electrolyte liquid is too low, the two small balls will fall to the limit position. At this time, the observation holes are in the infinity colorful '(the center is colorless and transparent, surrounded by a red ring), indicating Insufficient electrolyte, indicating that the battery cannot continue to use and must be replaced. If this detection is put on the dry reservoir, distilled water must be added. The English description is marked as 'adddistilledwater'.


Huizhong Valve Control Sealed Lead Acid Battery The voltage of 2V, 4V, 6V, 12V, 24V, 48V, 1.2V, 3V, 3.2V, 3.6V, 3.7V, 11.1V, 12.8V Wait
The battery is a large-scale components that have a long life of 3 to 4 years. It is 1 ~ 2 years, and the more often driving the car (especially long-distance use), the longer the battery life; Cars or buss that are often parked, often discharged but charge, and battery life is shorter.


Among them, Beijing, Tianjin arranged two inspection work groups. Liu Changgen, deputy director of the National Environmental Protection, said that the Ministry of Environmental Protection will also be implemented in the "2 + 26" city, the key task of "2 + 26" cities is committed, and the environmental quality is still prominent. In places where it is not obviously or even worsen, the special inspector of central environmental protection and special inspectors were reported to the Party Central Committee and the State Council was approved. "Compared to inspect and inspections, the power of the central environmental protection of the central environmental protection will be larger, because the local environmental protection inspectors have been fully understood." An official of the Ministry of Environmental Protection expressed its economic reports on the 21st century.
Battery Working Principle: When charging is charged with external electrical energy to regenerate internal active substances, store electrical energy as chemical energy, and then turn chemically converted into electrical energy output when discharging. When the battery is low, the electrolyte density is too low, the blue ball is sinking to the limit position, then the hole is exhibiting 'inner infrared colorless' (the center is red dot, the surrounding colorless transparent ring), indicating the battery The loss is serious, and it must be charged immediately, and the English is specified as 'chargingnecessary'.


Analysis of the daily maintenance method of the battery:


First, measure the floating charge voltage method


Second, the capacity measurement method


Third, internal resistance or conductivity test


Fourth, traditional offline capacity test method


Be
This detection method measures the accurate value of the battery's capacity and can clear whether the battery is a failure battery. However, this method has the following defects:


1. The battery must be separated from the system. If the city is suddenly interrupted during this period, the other set of batteries can be standing? Increase the risk of system paralysis.


2, the bulky electric wire requires multiple people to carry, and at least one person must measure the data.


3. Individual battery-side voltage may suddenly fall below the cutoff voltage during both measurement intervals, resulting in excessive discharge, as shown in Figure 3. The workload is too large, it is difficult to fully carry.


4, the whole set of batteries will take more than 20 hours, sometimes offline rectifiers, and is easy to cause a few batteries.


5, you must consume a lot of electrical energy and thermal energy.
