With the improvement of people's living standards, electric vehicles have become a more popular means of transportation, especially for short-distance travel. The convenience of electric vehicles exceeds that of cars. However, if you ride long distances, electric vehicles are a bit weak. This is inseparable from the choice of battery. At present, electric vehicle batteries are nothing more than lead-acid and lithium batteries. Many people know that electric vehicles have a short range and that lithium batteries are more durable, but they still choose the more common lead-acid battery . Among them, there are 3 major Pain points cannot be ignored!
Lithium batteries installed in electric vehicles are more durable and have longer battery life.
Everyone is familiar with lithium batteries. The correct term for them should be called lithium-ion batteries . They are widely used in the field of mobile phones and are relatively mature, but they are not used in electric vehicles. It is still in its infancy, especially in electric two-wheelers . Before 2019, although there were lithium electric vehicles and electric vehicles, most of them on the market were lead-acid electric vehicles. After 2019, the introduction of the new national standard for electric vehicles has placed lightweight requirements on electric bicycles, so the energy density is higher High-quality lithium batteries have gradually entered the public eye.
Electric bicycles are required to weigh no more than 55kg, the battery does not exceed 48V, and the motor does not exceed 400W. If ordinary lead-acid batteries are used, the battery life of the electric bicycle will be greatly reduced, and if lithium with higher power storage and lighter weight is used, Batteries, when meeting standards, can greatly improve the battery life of electric vehicles. It is for this reason that lithium electric vehicles now have a place and are gradually expanding the market.
Car owners prefer lead-acid batteries, and there are these 3 reasons
Although there are gradually more and more electric vehicles equipped with lithium batteries, which are very in line with actual needs, the reality is that more car owners still prefer lead-acid electric vehicles, lead-acid Batteries still maintain an absolute leading position and occupy most of the market. Kankan asked some car owners, coupled with feedback from netizens, and summarized the following three reasons that cannot be ignored. Many car owners also made it clear that if these problems are not solved, the lithium batteries will be used in vain.
1. The price of lithium electric vehicles is generally high
Electric vehicles are not a luxury product. The first thing many people look at when buying a car is the price, and the price of lithium electric vehicles is very high. Most electric bicycles equipped with lithium batteries are priced at 3,000 yuan. Going up, the main reason is still the high price of lithium batteries. Because lithium batteries lack core technology, important components such as separators, electrolytes , positive electrode materials, and negative electrode materials, as well as technology and equipment, are very dependent on imports, so the price of lithium batteries is generally high.
2. There is a risk of fire and explosion in lithium batteries
The structure of lead-acid batteries is relatively simple, consisting of positive and negative lead plates and electrolyte. The electrolyte is water and sulfuric acid, so it is not only cheap, but also less susceptible to accidents. If it catches fire, it will not explode. At most, it will cause bulges and crystallization.
Lithium batteries are different. They use electrolytes to isolate the positive and negative electrodes, and they are organic matter. Therefore, once exposed to external impact or high temperature, the organic matter may catch fire and explode. Although lithium batteries now have insurance measures such as BMS, and have undergone diaphragm puncture and other experiments before leaving the factory, theoretically there is still a risk of fire and explosion.
3. There are many inferior lithium batteries, which are prone to accidents.
Electric vehicle lithium battery explosions have occurred in many places. After investigation, most of these lithium batteries are inferior lithium batteries. So what are inferior lithium batteries? Nowadays, the recycling requirements for lithium batteries are very strict, so there are very few formal recycling companies. Those low-quality lithium batteries refer to illegally recycled used batteries, which are refurbished by unqualified small factories or handicraft workshops and then sold as new batteries.
There have been many accidents involving inferior lithium batteries, and the public has mistakenly believed that lithium batteries are unsafe, so everyone has chosen the more reliable lead-acid batteries.
talks about
To be honest, the application of lithium batteries in electric vehicles is indeed good, but the above three problems cannot be ignored. After all, the public rides electric vehicles for convenience, affordability, and safety. If lithium batteries are still so expensive, Inferior products are still rampant, even though cheap and safe lead-acid batteries will still be the main force in the future.
