Batteries are an item that everyone is familiar with and an indispensable part of electronic products.As a means of transportation powered by “electricity”, the battery is the “most important” component of an electric vehicle, which determines the battery life, lifespan, and cost-effectiveness of an electric vehicle. For vehicle owners, if they want to choose a durable electric vehicle, what kind of battery it is equipped with is very important. With the maturity of electric vehicle technology, not only electric vehicles have become rich and diverse, but various smart electric vehicles have also entered the consumer market. There are also more and more abundant batteries in electric vehicles. From the early VRLA of electric vehicles a hundred years ago to the rising stars of lithium cell, many batteries have appeared in recent years, including graphene cell and gel batteries.
At present, the commonly used batteries for electric vehicles are mainly VRLA, lithium cell, graphene cell and gel batteries. And they have their own characteristics, advantages and disadvantages. So, when choosing a battery for an electric vehicle, which one is better? The following is a set of comparisons that I have compiled for you. After reading it, it is clear at a glance.
Comparison of battery life of 4 kinds of batteries.
As a vehicle, battery life is very important. Although the battery life of electric vehicles is generally poor, with the innovation of battery technology, the battery life of many batteries is now very eye-catching, and there are even electric vehicles that can last for 200 kilometers. Therefore, even for some long-distance travel, if you choose the right battery, you can still use electric vehicles to commute. From the perspective of battery life, their order should be lithium cell > graphene cell > gel batteries > VRLA. Among them, lithium cell is used in electric vehicles, and they have the best performance in terms of battery life.
Comparison of the lifespan of four kinds of batteries.
The durability of electric vehicles depends to a large extent on the battery, and the durability of the battery is also criticized. Many electric vehicles have a serious decline in battery life after a year of use, and they need to be replaced with new batteries, which is not only very troublesome, but also costs more. However, not all battery life is this short.
From the perspective of battery life, there are actually big differences between different quality batteries. If you need to sort, my personal experience will be like this, graphene cell > lithium cell > gel batteries > VRLA. Graphene cells are only used in high-end electric vehicles, because the addition of “graphene” metal extends the battery life and can basically be used for more than 5 years. Lithium cell is charged and discharged about 500 to 1000 times, and it can be used for about 3 or 4 years. VRLA is generally within 3 years.
The above are some comparisons that I has listed in detail for you. I believe that you have your own ideas on battery selection in many aspects. Then finally, based on industry experience, I will give suggestions on the selection of these four kinds of batteries.
Suggestion 1: Choose VRLA for cost-effectiveness. In fact, it can be seen from the above that VRLA has no advantages in terms of life and battery life. But it is still the most selected battery, mainly because of its high cost performance. VRLA is economical and affordable, and under the requirements of the new national standard, the battery speed and battery life are limited. VRLA is sufficient for electric vehicles, so it has such a high market share.
Suggestion 2: Choose lithium cell or graphene cell for mid-to-high-end electric vehicles. Mid-to-high-end electric vehicles are generally equipped with high-end battery life as standard. Basically, electric vehicles with a price of more than seven or eight thousand have a battery life of more than 100 kilometers. These electric vehicles need to choose lithium cells or graphene cells, which can give full play to their advantages of speed and battery life.
Suggestion 3: Choose gel battery in cold environment. Many vehicle owners don’t know much about gel batteries. It is a technology imported from Germany. The principle is to improve the liquid electrolyte of the VRLA into a gel electrolyte, and the improved battery has the advantage of low temperature resistance. After the ordinary VRLA reaches 0 degrees, the power storage capacity will drop significantly, while the gel battery can adapt to the environment of minus 25 degrees. Therefore, in some particularly cold northern cities, choosing this type of battery has a great advantage.
In fact, the appearance and application of each type of battery means that it has irreplaceable advantages, otherwise there is no need to appear. Therefore, no matter what the comparison data is, it cannot be denied that a certain type of battery. The more types of batteries, actually give us more choices. Subdivided types of batteries can also help us find a more suitable battery for us. In other words, what suits you is the real deal.
