The 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:
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’.
Wuxi Huizhong Weiye Electric Co., Ltd. has a large sealed lead-acid battery capacity: 2V200AH, 2V250AH, 2V300AH, 2V350AH, 2V600AH, 2V800AH, 2V1000AH, 2V1800AH, 2V2000AH, 2V2500AH, 2V2000AH, 2V2500AH, 2V3000AH, 2V4000AH.
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.
[Abstract] Since 2008, it has been brewed. At the end of last year, the Environmental Protection Tax Law (“Environmental Protection Tax Law” (hereinafter referred to as the “Environmental Tax Law”) was constructed, and finally stepped into the countdown stage. The Times Weekly reporter Gao Yang sent from Guangzhou since 2008, the “Environmental Protection Tax Law” adopted by the Standing Committee of the National People’s Congress last year, finally stepped into the countdown stage. On August 22, Director of the Ministry of Environmental Protection Policy, Director, said, in the routine reporter meeting of the Ministry of Environmental Protection, the implementation of the Regulations on the Drafting Law Protection Law, three departments (Ministry of Finance, Taxation, Ministry of Environmental Protection) have been implemented. Notice, requires all places to prepare for taxation.
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
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.
V. Traditional online capacity test
At present, Datong County has filed a penalty for related enterprises and ordends the relevant departments to seriously rectify. Wang Guosheng came to Datong County Jiefang Road construction bridge to see the situation of sediment deposition, river dredging and water quality in Beichuan, etc. Rectification progress. Wang Guosheng pointed out that the party committees and relevant departments at all levels must strictly implement national environmental laws and regulations, increase the key areas, key industrial law enforcement inspections, and severely crack down on various types of behaviors that destroy the ecological environment, and the discharge. Resolutely shut down, it is necessary to ban the environmental protection requirements after rectification, and truly enable the ecological red line into an environmentally friendly high voltage line of illegal violations.
