Although the electric vehicle is small and the price is low, it is in the ownership, China's first most means of transportation, according to the data, China's car ownership is about 300 million, and the ownership of two-wheeled electric vehicles, has been about 370 million, China's electric vehicle ownership, production, sales are the forefront of the world.
At the same time as the development of electric vehicles, one of its industrial chain members of the battery, in our country also has a good development, according to the data show that China's lead-acid battery production accounted for about 1/3 of the world's total output, China is a lead-acid battery production country, a big consumer, an export power.
Huge consumer market, can always give birth to some super brands, China's lead-acid battery field, there are already big brands such as Tianneng, Chaowei, Camel, Nandu, etc., but for the process of choosing batteries for two-wheeled electric vehicles, in fact, it is still more common to Tianneng and Chaowei These 2 major brands are more common, some netizens asked, electric vehicles replace batteries, Tianneng and Chaowei choose which will be more durable? Insiders use data to tell you, so that you don't have to choose the wrong one again.
What kind of battery will be more durable?
Before understanding who will be more durable, we must understand what parameters the battery is mainly based on, because the small connoisseurs have seen a lot of related big V, shared the judgment of this topic, but many people still mainly rely on experience, subjective awareness, and such judgment, there will always be a little lack of objective factors, so in order to ensure "fairness", small connoisseurs try to "quantify" parameters.
First of all, it is very important that the quality, including the quality of the battery material, the manufacturing process, whether there is a "cadmium" element, and the first-line brands such as Tianneng and Chaowei, if it is a battery of the same price grade, in fact, in this regard, the gap is not large.
The second is the number of charge and discharge, the so-called number of charge and discharge, refers to the number of charge and discharge cycles that the battery can complete during use, once the number of charge and discharge times of the battery is exhausted, the battery will also fail, therefore, the number of charge and discharge is the core factor that determines the length of battery life, in the case of the same use environment.
Finally, the weight of the battery, although the number of cycle charge and discharge is the key factor affecting the battery, but this number is more or less publicized by the merchant, the owner can not be verified, and the main weight of the battery is the lead plate, so the heavier the battery, the more sufficient the lead plate, then, the higher the battery density, such a battery will be more durable, this judgment method, the owner can take it to distinguish themselves.
With the above method of judging whether the battery is durable, below, the small connoisseur is for the Tianneng battery and chaowei battery, data comparison, which is more durable at a glance, in order to avoid the difference in quality and material, we only compare the ordinary lead-acid batteries of chaowei and tianneng, including: chaowei no. 1, tianneng L3.
Data on the number of charge and discharge times of Tianneng batteries and Chaowei batteries
Electric vehicles are generally equipped with batteries, mainly based on 48V and 60V battery voltage, and the size of the battery is mainly based on 12AH, 20AH, 32AH these 3 kinds of capacity, we take the 20AH specifications of the battery as an example, the above figure Tianneng L3 battery clearly stated, the number of charge and discharge cycles is 400-600 times.
The chaowei lead-acid battery, in the description of the lead-acid battery, does not indicate the number of charge and discharge, but the small connoisseur through the query, its official website of the superwei superconducting graphene battery, clearly compared its own graphene battery and ordinary battery charge and discharge times, of which, superconducting graphene battery is 1000 times, while the ordinary lead-acid battery is 500 times.
Weight data of Tianneng batteries and Chaowei batteries
In lead-acid batteries, nearly 80% or so are lead materials, and the more lead is enough, the more "real materials" the battery, the longer its life will be, also with 20AH battery specifications, to compare the difference between Tianneng and Chaowei batteries.
Chaowei battery is actually in 20AH, will be slightly larger, its standard is 20.2AH, battery size 181×77×167mm, weight of 6 kg per battery, while 48V for 4 groups of 12V batteries, its weight is 6×4 = 24 kg, and 60V for 5 groups of batteries, its weight is 6×5 = 30 kg.
Tianneng battery is a standard 20AH battery, the battery size is 181×77×169mm, slightly higher, and this high is also reflected in the data, its battery weight per group is 6.25 kg, 48V20AH battery weight is 6.25×4 = 25 kg, 60V20AH battery weight is 6.25×5 = 31.25 kg.
Conclusion: In summary of the battery capacity and weight data, the number of charge and discharge times of Tianneng battery and Chaowei battery is within a range, and in terms of weight, Tianneng battery will be higher than Chaowei battery, then, on the basis of exactly the same quality, process materials and usage habits, the L3 lead-acid battery of Tianneng Battery will be more durable than the battery of Chaowei No. 1.
Of course, small connoisseurs are not saying that Chaowei's battery must not have the durability of the tianneng battery, after all, we are only comparing one of their several brands of products, today here, mainly to teach everyone to learn to judge the battery durability of the method, so that when the electric vehicle replaces the battery, you can judge on your own, see which batteries will be more durable, do not worry about changing to the battery that is not durable.
So, which do you think will be more durable, Tianneng or Chaowei? Welcome to comment and exchange, pay attention to electric vehicle experts, and share electric vehicle related information and views every day.
