In recent years, electric bicycles have become a popular means of transportation for commuters and a beautiful scenery in people's lives. As is well known, a good electric vehicle must have a good battery to ensure its driving range. However, some numbers and letter symbols on the battery often confuse car owners, such as the "6-DZM-20" on the Tianneng battery. What does that mean? The explanation on the manual is also somewhat understood. Today, we will popularize the size and model of electric vehicle batteries to help consumers choose good batteries.
Firstly, let's talk about the classification of battery models. Generally, electric vehicle batteries are divided into four types: 24V, 36V, 48V, 60V, and 64V, with 36V and 48V being the most common.
36V is commonly used in two types: 36V10AH and 36V12AH, with some also using 36V14AH, 36V17AH, and 36V20AH.
The commonly used 48V are: 48V10AH, 48V12AH, 48V14AH, 48V17AH, 48V20AH.
So how do you know the size and model of your electric vehicle battery? Generally speaking, there are two methods. Just look at the output current of the charger and compare the following parameters to determine the type of battery:
Prompt, check the output voltage * * VDC * * A on the charger
The output voltage of 36V is 36V-42VDC * * A.
If it is 1.5A, then it is 10AH.
If it is 1.6A, then it is 12AH.
The output voltage of 48V is 48V-59VDC * * A.
If it is 1.7A, it is 48V10AH.
If it is 1.8A, it is 48V12AH.
If it is 2.0A, it is 48V14AH.
If it is 2.3A, it is 48V17AH.
If it is 2.5A, it is 48V20AH.
The first method sometimes doesn't work because some poor chargers don't even indicate these parameters, so we have to use the second method. This method is the simplest, most direct, and most practical, which is to open the battery box and count how many batteries there are. If it is three, then generally it is 36V.
Once the voltage is determined, determine the capacity. If the battery is labeled as 6-DZM-10, then it is 10AH; if it is 6-DZM-12, then it is 12AH, and so on.
Of course, there are also some small manufacturers who have the phenomenon of electric vehicle battery size being falsely labeled, such as 6-DZM-14, which is actually a national standard of 10-12AH, and 6-DZM-20, which is actually a national standard of 17AH. Therefore, it is recommended that when purchasing batteries, you choose a reputable battery manufacturer
