Electric vehicle choose lead-acid battery, or lithium battery?

Electric vehicle is our very common means of transportation, in the performance of electric vehicle, range is particularly important, and determine the range of electric vehicle mainly depends on the battery, including the battery category and model, capacity, etc.. At present, the battery of electric vehicle mainly has lead-acid battery and Lithium Battery two kinds, we choose the battery, lead-acid battery is good, or lithium battery is good? Which is more practical? Which one is better? Let me tell you today.

Electric vehicle choose lead-acid battery, or lithium battery?

Batteries are the source of energy reserve for electric vehicles. Although there are a variety of battery markets for electric vehicles, such as graphene batteries, black gold batteries and Lithium Iron Phosphate Batteries, they mainly fall into two categories: lead-acid batteries and Lithium Batteries. Today, we will analyse the real value of these two batteries through their different advantages and disadvantages.

Analysis of the three categories of lead batteries

Lead-acid battery is a particularly common battery in the market at present, accounting for about 75% of the current market, because of its economic benefits, convenient purchase and high safety characteristics, loved by the majority of electric vehicle users.

Lead-acid batteries fall into three sub-categories: regular lead-acid batteries, black gold batteries and graphene batteries, all of which have different ranges and price points for the same model. In general, graphene batteries cost more and regular lead-acid batteries cost less. But the actual usage is the opposite.

For example, graphene batteries have a longer range than standard lead-acid batteries for the same model, but they are also much more expensive, so most users choose standard lead-acid batteries.

Analysis of the three categories of lithium batteries

In recent years, the growth share of lithium batteries has been relatively high. In the early years, the market share of lithium battery was less than 10%, and now it has reached about 25% in some places. Lithium battery mainly includes three types: The market share of these three types of batteries is similar to that of lead-acid batteries above, i.e. the most commonly used three-way lithium-ion batteries account for more market share and are relatively affordable.

Lead-acid batteries are more practical and cost-effective

Why am I so direct about the advantages of lead-acid batteries? Because lead-acid batteries are more practical than conventional Car Batteries, in two ways:

1, lead-acid battery price is more affordable, generally only one-third of the price of the same type of lithium battery.

For electric vehicles, mainly practical and easy to use, ordinary people generally do not require driving range is particularly far, although lithium battery range is far, relatively light weight, but at present most people ride luxury car or small chartered car, volume enough to accommodate the battery, but the price is much lower, naturally is the people more hope.

2. Lead-acid batteries are safer and less prone to spontaneous combustion.

In the past two years, spontaneous combustion caused by Electric Vehicle Batteries, mainly electric vehicles equipped with lithium batteries, because of the high density inside lithium batteries, heat resistance is poor, if overheating, such as summer or charge for too long, over the temperature of the load, it may cause spontaneous combustion. In particular, the safety of inferior lithium batteries should be more cautious. And lead-acid battery stability is relatively high, generally have little spontaneous combustion phenomenon.

3. Lead acid battery is more convenient and valuable.

Although the service life of lithium batteries is generally twice that of lead-acid batteries, but if the time to buy, lead-acid batteries are more convenient, generally lead-acid batteries can be recycled, that is, waste lead-acid batteries can also be depreciated. But if the lithium battery is old, there is little value in recycling.

Lithium-ion batteries last longer, have a longer range and are lighter

Of course, lithium batteries also have advantages, in three aspects:

1. The service life of lithium batteries is longer.

Compared with lead-acid batteries, lithium-ion batteries tend to last twice as long as similar lead-acid batteries, which means a higher value for durability.

2. Lithium batteries have a longer range.

Lithium-ion batteries of the same type have a much higher range than lead-acid batteries, and even graphene batteries, which are relatively expensive among lead-acid batteries, do not necessarily have a higher range than lithium batteries. So lithium batteries are used in many new energy vehicles.

3. Lithium batteries are lighter in weight.

This is more suitable for the users of new energy vehicles and the pursuit of small and lightweight electric bicycles. The choice of lithium battery is more lightweight, and the battery extraction is more convenient.

summarize

Lead-acid battery and lithium battery are currently the two major categories of Electric Vehicle Battery, each has its own characteristics, if from the economic practical point of view, choose lead-acid battery is more practical and cost-effective, but if the pursuit of mileage, the pursuit of durability and portability, or lithium battery is more appropriate, of course, lithium battery price is also higher, but longer service life.
