The models of lead-acid batteries used in automobiles are named according to certain standards. The battery models used in the domestic market are mainly named according to national standards, Japanese standards, German standards, and American standards.

A.Taking the battery model 6-QAW-54a as an example, the national standard battery for the first project is explained as follows:

1.6 represents a composition of 6 single cell batteries, each with a voltage of 2V, i.e. a rated voltage of 12V;

2. Q represents the purpose of the battery; Q represents the automotive starting battery; M represents the motorcycle battery; JC represents the marine battery; HK represents the aviation battery; D represents the electric vehicle battery; F represents the valve regulated battery;

3. A and W represent the types of batteries; A represents dry load batteries; W represents maintenance free batteries; if not marked, it represents ordinary batteries;

4.54 indicates that a battery with a rated capacity of 54Ah is capable of being fully charged, and the amount of electricity output by the battery is discharged at a rate of 20h at room temperature for 20h;

5. The corner mark a represents the first improvement to the original product, followed by the corner mark b represents the second improvement, and so on. Note: ① Adding D after the model indicates good low-temperature starting performance, such as 6-QA-110D; ② Adding HD after the model indicates high vibration resistance; ③ Adding DF after the model indicates low-temperature reverse installation; and so on, such as 6-QA-165DF

B.In 1979, the Japanese JIS standard battery model was represented by Nippon's N in Japan, followed by the size of the battery compartment, which was represented by a number close to the rated capacity of the battery, such as NS40ZL

1. N represents the Japanese JIS standard;

2. S represents miniaturization, which means that the actual capacity is less than 40 Ah and is 36 Ah;

3. Z indicates good starting and discharging performance under the same size, while S indicates that the pole terminal is thicker than the same capacity battery, such as NS60SL; Generally speaking, the positive and negative poles of a battery have different diameters to avoid reversing the polarity of the battery

4. L indicates that the positive pole is working on the left end, R indicates that the positive pole is working on the right end, such as NS70R. From the direction away from the battery pole to 1982, the Japanese standard battery model was implemented according to the new standard. For example, 38B20L is equivalent to NS40ZL. 1.38 indicates the performance parameters of the battery. The larger the number, the more electricity the battery can store. 2. B indicates the width and height code of the battery. The width and height combination of the battery is determined by 8 One of the letters represents A to H, and the closer the character is to H, the greater the width and height of the battery. 3.20 represents a length of approximately 20cm. 4. L represents the position of the positive terminal. When viewed from a distance from the battery pole, the positive terminal is labeled R at the right end and L at the left end

C. The German DIN standard battery takes the battery model 544 34 as an example, and the explanation is as follows:

1. The first 5 indicates that the rated capacity of the battery is below 100Ah; The beginning 6 indicates that the battery capacity is between 100Ah and 200Ah; The beginning 7 indicates that the rated capacity of the battery is above 200Ah. For example, the rated capacity of the 544 34 battery is 44Ah; The rated capacity of the 610 17MF battery is 110 Ah; The rated capacity of the 700 27 battery is 200 Ah.

2.The last two digits of the capacity indicate the battery size group number.

3. MF represents maintenance free type.

D.The BCI standard battery in the United States is an example of a battery with a model of 58 430 and a capacity of 12V 430A 80min. The explanation is as follows:

1.58 represents the battery size group number 

2.430 indicates a cold start current of 430A

3.80min indicates that the storage capacity of the battery is 80min

4. American standard batteries can also be represented in this way. 78-600 represents the battery size group number, 600 represents the cold start current of 600A, indicating the minimum current that can be obtained in a specific sense under the conditions of -17.8 ℃ and -28.9 ℃. This indicator compares the starting capacity of the battery to the engine displacement, compression ratio, temperature, starting time, and technical status of the engine and electrical system The minimum voltage used for ignition, which is an important variable, refers to the minimum current that a fully charged 12V battery can supply when its terminal voltage drops to 7.2V within 30 seconds. The cold start rating gives the total current value. ② The reserve capacity is used to determine the RC. The approximate time that a car can operate at night by igniting the battery and providing the minimum circuit load when the charging system is not working can be specified It is expressed as the discharge time of a fully charged 12V battery at 25 ± 2 ℃ at a constant current of 25A until the battery terminal voltage drops to 10.5 ± 0.05V
