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:Be
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.

Common imported batteries include: Sanyo battery, Panasonic battery, LG battery, Samsung lithium battery.
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.
The article said, in addition, China's power grid transformation is not in the construction speed of the solar power plant and wind farm, causing a lot of energy waste. At the same time, China's manufacturers are like most manufacturers in the world, and they feel the slowdown in the growth of hedge global energy demand, which is increasingly urgently needed to reduce costs and improve efficiency. Although there is the above obstacles, technological innovation should help China's manufacturers have improved productivity, saving consumers. According to the report of the McKinsey Global Research Institute, by 2035, the article said that such cost savings, but also depends on the adoption of new technologies, but also depends on whether policy makers and enterprises can adapt to the new environment, but * important It depends on China.
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
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.
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
On September 3, the news report said that the Shandong Provincial Economic and Information Commission has issued the "Reply to the Development of Shandong Refining Energy Group Co., Ltd." on September 1st. Refining Enterprises forms Shandong Refining Energy Group Co., Ltd. The group was initiated by the backbone enterprises such as Shandong Dongming Petrochemical Group Co., Ltd., Shandong Qingyuan Group Co., Ltd., which was obtained from import crude oil. In February 2016, China Petroleum Purchasing Alliance jointly initiated by 14 local refinery companies and the provinces outside Shandong Province were formally established. The procurement alliance is a platform for Pacific Commercial Holdings Co., Ltd. to which Tin Ming Petrochemical is a platform, and organizes imported crude oil in an imported crude oil quota. The main purpose is to strengthen international market voice and bargaining.
