Why lithium batteries are a life-saving straw for low-speed electric vehicles

Who is the lifeline of a low-speed electric car? The answer is: lithium battery low speed electric car. Recently, the high-speed electric vehicle's fraudulent storm has made the author sigh. In the case of the high-speed electric vehicle problem, almost no one has paid attention to the development and progress of the lithium battery low-speed electric vehicle.

Lithium battery low-speed electric vehicles are very different from traditional lead-acid batteries for low-speed electric vehicles. The main difference is the difference between power batteries. Lithium battery low-speed electric vehicles are made of nationally recognized and supported new energy vehicle production technologies and accessories. It is three kinds of ternary lithium battery, lithium iron phosphate and lithium manganese oxide battery.

All of the above types of batteries have advantages and disadvantages, roughly summarized as:

Ternary lithium battery: advantages: high energy density and high tap density. Disadvantages: poor high temperature resistance and poor life.

lithium iron phosphate battery: advantages: long life, large charge and discharge rate, good safety, high temperature, harmless elements, low cost. Disadvantages: low energy density and low tap density (bulk density).

Manganese lithium battery: advantages: high tap density and low cost. Disadvantages: Poor temperature resistance, lithium citrate temperature rises sharply after long-term use battery life is seriously attenuated (such as Nissan electric car LEAF). (Note: Lithium cobaltate is usually used in 3C products, which is extremely poor in safety and is not suitable for power batteries).

At present, the power batteries of high-speed new energy vehicles in our country are often dominated by ternary lithium batteries and lithium iron phosphate batteries. Because of the support at the national level, most lithium battery manufacturers now have the core production technology of lithium batteries, and their safety, reliability and sustainability have been greatly improved.

The national and local governments have greatly supported the development and application of high-speed electric vehicles, and the effect is self-evident. However, the lithium-ion low-speed electric vehicle is a blank. Here, I will discuss the market prospects and applications of lithium-ion low-speed electric vehicles.

The electric vehicles currently on the market are mainly divided into high-speed and low-speed. The sales price of high-speed electric vehicles ranges from 35,000 to several hundred thousand (subsidized price), but the current low-speed electric vehicles are sold for only 10,000. 40,000, the largest sales volume is about 2W low-speed electric vehicles, and now the price war of low-speed electric vehicles has become hot, manufacturers and dealers are crying sales. (Low speed electric cars have reached the edge of the cliff, comrades should pay attention)

But think about it, high-speed electric cars can use lithium batteries as power batteries why Low-speed electric vehicles can't use lithium batteries as power batteries? I think the reasons are as follows: high manufacturing costs, high procurement cost of lithium batteries, blank market for lithium-ion low-speed electric vehicles, and high technical requirements for lithium-ion electric vehicles. There are no low-speed electric vehicle manufacturers that can meet the requirements.

If you can seize the great opportunity of the development of lithium-ion low-speed electric vehicles, then you can lead the low-speed electric vehicle industry for at least five years. Think about it, now the country sells at least 1.5 million high-speed and low-speed electric vehicles every year. If there is a company that can control the manufacturing cost of lithium-ion low-speed electric vehicles and successfully produce lithium-ion low-speed electric vehicles for sale, it can at least replace 80% of lead-acid battery low-speed electric vehicles.

When the lithium-electric low-speed electric car comes out, who will sell it to buy a lead-acid battery low-speed electric car can eat the first cake in the lithium low-speed electric car market, let us wait and see.
